Productivity Linked Bonus

Productivity Linked Bonus is the annual Diwali bonus for Railways, Posts and defence production staff, computed on a Rs. 7,000 monthly emoluments ceiling.

Updated 17 July 2026 · Reviewed by Salary-Calculator.in

Productivity Linked Bonus (PLB) is an annual bonus paid to central government employees in the departments where output can be measured against a fixed target, chiefly the Railways, the Department of Posts, the defence production units, and the Employees’ Provident Fund Organisation, with the number of days announced each year and the amount computed on a monthly emoluments ceiling of Rs. 7,000. It is sanctioned by the Ministry of Finance and the administrative departments through annual orders, typically before Dussehra and Diwali.

This article covers the whole bonus framework for a government employee: what PLB is and which departments run a scheme, how the number of days is fixed and paid, the Rs. 7,000 calculation ceiling and the 30.4-day divisor that turn a number of days into a rupee figure, the worked examples that most employees look for, the eligibility and pro-rata rules, the distinct treatment of casual labour, the difference between PLB and the non-productivity-linked ad-hoc bonus that everyone else receives, the tax position, and the standing demand to lift the ceiling.

Bonus is one of the few payments in the government pay packet that does not scale with rank once the ceiling bites. A senior clerk and a junior one, both earning above Rs. 7,000 a month, receive exactly the same bonus for the same number of days, because the sum is worked out on a notional Rs. 7,000, not on their actual pay. That single design choice, more than any other, shapes how the bonus is felt and why it is the subject of a long-running grievance.

What PLB is, and where it applies

PLB rewards measured productivity. In a department whose output can be counted, freight and passenger traffic on the Railways, mail and financial-services volumes in the Department of Posts, production in the ordnance factories and naval dockyards, or claims settled and accounts maintained in the Employees’ Provident Fund Organisation, the government negotiates a formula that links a number of days of bonus to the productivity achieved in the accounting year. When productivity rises, the number of days can rise; when it falls, the days can fall. The bonus is therefore not a fixed festival payment but a variable one, tied in principle to what the workforce produced.

The departments and undertakings that run a PLB scheme include:

The Indian Railways , the largest single block of PLB recipients, covering non-gazetted railway staff across zones and production units.
The Department of Posts , covering postal and RMS staff.
The defence production units, the ordnance factories (now the Ordnance Factory Board successor companies), the naval dockyards, and the workshops and depots under the Army, Navy and Air Force, along with the quality-assurance organisations.
The Employees’ Provident Fund Organisation and the Employees’ State Insurance Corporation, which run their own PLB schemes.

Employees in the general central secretariat, the attached and subordinate offices, and every other department without a measurable-output scheme do not receive PLB. They receive the non-productivity-linked ad-hoc bonus instead, discussed below. The line between the two is the existence of a productivity-measurement scheme, not the seniority or the pay of the employee.

Origins: the 1979-80 railway scheme

The Indian Railways was the first departmental undertaking of the central government to adopt a Productivity Linked Bonus, from the year 1979-80. The formula was conceptualised in November 1979 by an agreement between the Ministry of Railways and the two recognised staff federations, the All India Railwaymen’s Federation and the National Federation of Indian Railwaymen, and was approved by the Cabinet. It was introduced deliberately as an alternative to a bonus on the lines of the Payment of Bonus Act, 1965 , the reasoning being that the Railways, as infrastructure central to the economy, should reward the workforce for measured output rather than pay a profit-share bonus under the Act.

The Act does not apply to the Railways, but its broad principles were borrowed for two specific purposes: the definition of “wages” or “salary” for the calculation, and the idea of a wage or pay ceiling. That borrowed ceiling is the ancestor of the Rs. 7,000 figure in use today. The scheme was designed to be reviewed every three years, so the productivity formula and the terms are periodically renegotiated between the Railway Board and the federations.

A change in 1995-96 widened the reach of the scheme. From that year, all Group C and the erstwhile Group D railway employees were paid PLB without any wage ceiling on eligibility, so the wage ceiling survives only as a calculation ceiling, not as a bar to who may draw the bonus. The other PLB schemes, in the Department of Posts, the defence production units, and the Employees’ Provident Fund Organisation, were introduced later on the railway model, each with its own productivity measure and its own annual number of days.

The railway productivity formula

The railway scheme measures productivity by relating the traffic the Railways carried to the staff who carried it. The output is taken as the net tonne-kilometres of goods traffic plus the passenger-kilometres converted to an equivalent goods-traffic figure, and this is set against the average staff strength for the year. When output per employee rises, the formula can yield more days of bonus; when it falls, fewer. In practice the number has settled at 78 days for several consecutive years, which is why the railway bonus now behaves much like a fixed annual payment capped at the ceiling rather than a sharply variable one.

The other schemes use measures suited to their own work: mail and financial-services throughput in the Department of Posts, physical production in the ordnance factories and naval dockyards, and claims and accounts volumes in the Employees’ Provident Fund Organisation. Each scheme converts its productivity measure into a number of days through its own negotiated formula, and each is put up for approval before the festival season.

How the number of days is fixed

The number of days of PLB is decided afresh each year. For the Railways, the largest scheme, the number is worked out under a productivity formula that the Ministry of Railways and the staff federations negotiated, and it is then put to the Union Cabinet for approval before it is paid. The Cabinet’s approval is the step that makes the annual bonus news: the announcement of “78 days” or “so many days” of railway bonus each autumn.

For the accounting year 2023-24 the Cabinet approved 78 days of PLB for eligible non-gazetted railway employees. Seventy-eight days has been the railway figure for several consecutive years, which tells its own story: the notional formula has in practice settled at a stable number, and the bonus behaves more like a fixed annual payment capped at the ceiling than like a genuinely variable productivity reward. The Railway Board issues the operative order each year, for 2023-24 through its Railway Board circular of 2024.

Each PLB scheme fixes its own number of days, so the Posts figure and the defence-production figures need not match the railway figure. What they share is the calculation method that converts the days into money, which is common across the schemes and across the ad-hoc bonus.

The Rs. 7,000 ceiling and the 30.4 formula

Two numbers do all the work in a bonus calculation: the calculation ceiling and the daily divisor.

The calculation ceiling is Rs. 7,000 of monthly emoluments. The bonus is worked out on the average emoluments in the year, or on Rs. 7,000, whichever is lower. So for anyone whose average monthly emoluments exceed Rs. 7,000, and that is almost every regular employee under the 7th Central Pay Commission pay scales, the bonus is computed as though they earned Rs. 7,000 a month, however much they actually earn. The ceiling was raised to Rs. 7,000 from Rs. 3,500 with effect from 1 April 2014, by the Department of Expenditure Office Memorandum No. 7/4/2014-E.III(A) dated 29 August 2016, and it has stayed at Rs. 7,000 since.

The daily divisor is 30.4, the average number of days in a month. The bonus for one day is the monthly emoluments figure, capped at Rs. 7,000, divided by 30.4. That daily figure is then multiplied by the number of days announced.

Putting the two together, the bonus for an employee earning above the ceiling is:

Bonus = (Rs. 7,000 divided by 30.4) times the number of days

The one-day rate on the ceiling is Rs. 7,000 divided by 30.4, which is Rs. 230.26. The table below turns that into the figures an employee actually receives:

Number of days announced	Calculation on Rs. 7,000 ceiling	Bonus (rounded to nearest rupee)
30 days	7,000 times 30 divided by 30.4	Rs. 6,908
60 days	7,000 times 60 divided by 30.4	Rs. 13,816
78 days (railway PLB)	On the Rs. 7,000 ceiling	Rs. 17,951 (government-announced maximum)

The 30-day figure of Rs. 6,908 is the one most central government employees see, because 30 days is the standard ad-hoc bonus. The 78-day figure is the railway PLB, for which the government announces a maximum of Rs. 17,951 per eligible employee on the Rs. 7,000 ceiling. All payments are rounded to the nearest rupee.

A worked example makes the ceiling concrete. Take a railway technician whose basic pay plus dearness allowance is Rs. 55,000 a month, and a PLB of 78 days. Because the actual emoluments of Rs. 55,000 exceed the Rs. 7,000 ceiling, the calculation uses Rs. 7,000, not Rs. 55,000, so the technician receives the announced maximum of Rs. 17,951. A colleague earning Rs. 90,000 a month receives the identical Rs. 17,951, because both are computed on the same notional Rs. 7,000.

Employees below the ceiling

The ceiling only caps the calculation; it does not set a floor. An employee whose average monthly emoluments are below Rs. 7,000 is paid on their actual emoluments, not on the ceiling, because the rule is “average emoluments or the ceiling, whichever is lower”. Under the 7th Central Pay Commission pay matrix the minimum basic pay is Rs. 18,000, so a regular employee is effectively always above the ceiling, and the below-ceiling rule now matters mainly for casual labour.

Casual labour

Casual labourers with a sufficient record of service are eligible for the ad-hoc bonus, on a separate and lower ceiling. A casual labourer who has worked for at least 240 days in each year for three years or more, in an office on a six-day week, or 206 days a year for three years in an office on a five-day week, qualifies. Their bonus is computed on a ceiling of Rs. 1,200 a month, so 30 days works out to Rs. 1,200 times 30 divided by 30.4, which is Rs. 1,184. Where a casual labourer’s actual monthly emoluments fall below Rs. 1,200, the lower actual figure is used instead.

Eligibility and pro-rata

The eligibility conditions are common to PLB and the ad-hoc bonus. An employee must satisfy two tests:

In service on the last day. The employee must have been in service on 31 March of the accounting year for which the bonus is paid.
Six months of continuous service. The employee must have rendered at least six months of continuous service during that accounting year to draw the full bonus.

An employee who has served between six months and one year in the year receives a pro-rata bonus, worked out in proportion to the period served. An employee with less than six months of continuous service is normally not eligible, though there are specific relaxations for those who retired, died in service, or were discharged after completing the qualifying period. The bonus is confined to non-gazetted employees; group A officers and gazetted group B officers are outside both PLB and the ad-hoc bonus.

Certain periods and events are treated specially when the six-months test is applied:

Retirement, death, and discharge. An employee who retired on superannuation, died in service, or was discharged after having rendered the qualifying six months of continuous service in the accounting year is eligible, and in the case of death the bonus is paid to the family.
Deputation and transfer. An employee who moved between eligible offices during the year generally carries the continuous-service credit across the move, so a transfer does not by itself break the qualifying period. An employee who moved from a PLB department to a non-PLB one, or the reverse, is dealt with under the order of the department paying the bonus.
Leave and dies-non. Regular leave counts as service for the qualifying period, but a period treated as dies-non, and certain periods of unauthorised absence, do not count and can reduce the continuous service below the threshold.
Resignation. An employee who resigned before the last day of the accounting year is normally not eligible, because the in-service-on-31-March test is not met.

New entrants who joined during the year and have not completed six months of continuous service by the end of the accounting year do not qualify for that year, and draw their first bonus in the following cycle once the qualifying period is complete.

When and how it is paid

The bonus is timed to the festival season. The railway PLB and the ad-hoc bonus are both released before the Dussehra and Puja holidays, so the money reaches employees ahead of Diwali, which is why it is known popularly as the Diwali bonus. The Cabinet approval of the railway figure, and the Finance Ministry order for the ad-hoc bonus, are issued in September or early October each year for this reason.

Payment is made by the drawing and disbursing officer as a single credit to the salary account, in the accounting year following the one for which it is earned. So the bonus for the accounting year 2024-25 is paid in the second half of 2025. It is a one-time annual payment, not a monthly one, and it is shown as a distinct line in that month’s pay, over and above the regular salary. Tax is deducted at source on it in that month along with the rest of the pay, which is why the take-home in the bonus month can look different from a normal month even though the annual position is unchanged.

PLB versus the ad-hoc bonus

The two bonuses are easy to confuse because they are paid at the same time of year, use the same ceiling and the same divisor, and land in the same bank accounts each Diwali. The difference is what they are paid for and who receives them.

Productivity Linked Bonus goes to the departments with a productivity-measurement scheme, and the number of days is meant to reflect measured output. The railway 78 days is the flagship figure.
Non-productivity-linked ad-hoc bonus goes to the remaining Group C and non-gazetted Group B central government employees, who are not covered by any PLB scheme, at a flat 30 days in recent years. It is called “ad-hoc” precisely because there is no productivity formula behind the number; the government simply fixes a number of days, and 30 has been the figure for years.

Both are sanctioned by annual orders. The ad-hoc bonus order for a given year is issued by the Department of Expenditure, for the accounting year 2024-25 through Office Memorandum F. No. 7/24/2007-E.III(A), granting 30 days at Rs. 6,908 for those above the ceiling. The railway PLB is issued by the Railway Board. Both extend, by their own terms, to the eligible employees of the central paramilitary forces, the armed forces, and the Union Territory administrations that follow the central pattern of emoluments.

Not the Payment of Bonus Act

A common error is to read the government bonus against the Payment of Bonus Act, 1965 . The Act governs bonus in factories and other establishments in the private sector and in public-sector enterprises, setting a minimum bonus of 8.33 per cent and a maximum of 20 per cent of wages, on its own wage ceiling. It does not apply to a civil servant. Bonus for central government employees is paid under separate executive PLB schemes and the annual Finance Ministry and departmental orders, so the Act’s percentages, its allocable-surplus mechanics, and its wage ceiling are all irrelevant to a government servant’s bonus. The only feature the two share is the idea of a calculation ceiling, and even there the figures differ.

The tax position

The bonus is fully taxable. It is part of salary income in the year of receipt, no provision of the Income-tax Act exempts it, and it is added to gross salary and taxed at the applicable slab rate. The drawing and disbursing officer deducts tax at source on it along with the rest of the salary. Because it is paid in a single month, it can push that month’s tax deduction up, but over the year it is simply part of the taxable salary, as the income tax for government employees article explains. It also forms part of the figure an employee sees in the take-home salary for the month it is paid.

Bonus does not count as emoluments for pension or gratuity. Retirement benefits are worked out on basic pay and dearness allowance , and the bonus, being neither, does not enter the gratuity or pension calculation.

The demand to lift the ceiling

The Rs. 7,000 ceiling is the heart of the grievance over government bonus. It was last revised in 2014, and the pay of every regular employee has since risen far above it under the 7th Central Pay Commission, so the bonus has been frozen in real terms while pay has climbed. An employee earning Rs. 60,000 a month receives a bonus computed on Rs. 7,000, less than a ninth of their actual monthly emoluments.

The staff side of the national council has pressed for the ceiling to be removed, so that both PLB and the ad-hoc bonus are computed on actual emoluments of basic pay plus dearness allowance rather than a notional Rs. 7,000, and has put the demand to the 8th Central Pay Commission . Whether the ceiling is raised or removed is a matter for the government and the pay commission, and no revised ceiling can be stated as fact until an order issues. Until then the position is the one set out above: a Rs. 7,000 ceiling, a 30.4 divisor, and a number of days fixed each year.

Frequently Asked Questions (FAQs)

What is Productivity Linked Bonus and who gets it?

Productivity Linked Bonus (PLB) is an annual bonus paid to central government employees in departments where output can be measured against a target, mainly the Railways, the Department of Posts, the defence production units such as the ordnance factories and the naval dockyards, and the Employees’ Provident Fund Organisation. Employees in departments without a measurable-output scheme instead receive the non-productivity-linked ad-hoc bonus.

How is Productivity Linked Bonus calculated?

The number of days is announced by the government each year for each department. The daily rate is the average monthly emoluments, or the calculation ceiling of Rs. 7,000 whichever is lower, divided by 30.4. That daily figure is multiplied by the number of days announced. For an employee whose emoluments exceed Rs. 7,000, thirty days of bonus works out to Rs. 7,000 times 30 divided by 30.4, which is Rs. 6,908.

Why is the bonus capped at Rs. 7,000 when my salary is much higher?

The bonus is computed on a notional monthly emoluments ceiling of Rs. 7,000, not on actual pay, for anyone earning above that figure. The ceiling was set at Rs. 7,000 with effect from 1 April 2014, raised from Rs. 3,500, by the Department of Expenditure Office Memorandum of 29 August 2016, and it has not moved since. This is why a well-paid employee and a junior one who both cross Rs. 7,000 receive the same rupee bonus for the same number of days.

How many days of Productivity Linked Bonus do Railway employees get?

It varies year to year with the productivity achieved. For the accounting year 2023-24 the Cabinet approved 78 days of PLB for eligible non-gazetted railway employees, calculated on the Rs. 7,000 emoluments ceiling, so an eligible railway employee earning above that ceiling received about Rs. 17,951 for 78 days.

What is the difference between PLB and the ad-hoc bonus?

PLB is paid in departments where productivity can be measured against a target and the number of days reflects that productivity. The non-productivity-linked ad-hoc bonus is paid to the remaining Group C and non-gazetted Group B employees, at a flat 30 days in recent years, precisely because their output cannot be measured the same way. Both use the same Rs. 7,000 ceiling and the same 30.4 divisor, so only the number of days and the covered group differ.

Who is eligible for Productivity Linked Bonus?

An employee must have been in service on 31 March of the accounting year and must have rendered at least six months of continuous service during that year. Those with service between six months and one year receive a pro-rata amount. The bonus is normally confined to non-gazetted employees; group A and gazetted group B officers are usually outside it.

Is Productivity Linked Bonus taxable?

Yes. The bonus is part of salary income and is fully taxable in the year of receipt. No provision of the Income-tax Act exempts it, so it is added to gross salary and taxed at the applicable slab rate, with tax deducted at source by the drawing and disbursing officer.

Is government PLB paid under the Payment of Bonus Act, 1965?

No. The Payment of Bonus Act, 1965 governs bonus in factories and establishments in the private and public-enterprise sector. Bonus for central government servants is paid under separate executive Productivity Linked Bonus schemes and the annual Finance Ministry and departmental orders, not under that Act, so the Act’s minimum and maximum bonus percentages do not apply to a government servant.
