Pension commutation calculator
For central government pensioners. Enter your basic pension and your age next birthday. The factor comes from the official commutation table, which covers ages 20 to 81, and Dearness Relief stays on your full pension.
Applied for with your pension papers, commutation becomes absolute the day after retirement, so retiring at 60 means age next birthday 61. The pension is cut from the day the lump sum is paid, and the full pension returns 15 years later.

How commutation is worked out
Under the Central Civil Services (Commutation of Pension) Rules, 1981, a central government pensioner can give up (commute) up to 40% of the basic pension for a one-time lump sum, called the commuted value of pension:
Lump sum = pension commuted per month × 12 × commutation factor
The factor depends on your age next birthday on the date commutation becomes absolute. If you apply with your pension papers, that is the day after you retire, so someone retiring at 60 uses age 61 and a factor of 8.194. The table, used for every commutation that became absolute on or after 2 September 2008, is based on LIC mortality tables and an 8% interest rate, so the factor falls as age rises. It stops at age 81.

Which date fixes your age
- Applied with your pension papers: commutation becomes absolute the day after you retire.
- Applied in Form 1 within a year of retiring: it becomes absolute on the day your Head of Office receives the form.
- Applied more than a year after retiring: you need a medical examination, and it becomes absolute on the day the medical authority signs its report. The authority can add years to your age if your health is poor, which lowers the factor, and you can then withdraw the application within 14 days.
Any fraction of a rupee in the pension commuted is ignored, and the lump sum is rounded up to the next rupee.
What happens to your monthly pension
- The basic pension paid drops by the amount commuted, from the day the lump sum is paid.
- Dearness Relief stays on the full pension. DR is worked out on the basic pension before commutation, so the cut applies only to the basic part.
- The commuted part is restored 15 years after the cut starts, and the full basic pension is paid again from then on.
- Family pension is not affected. It is worked out on the last pay, and nothing is recovered from the family if the pensioner dies before restoration.
Is commuting worth it?
That depends on what you would do with the money and on how long you expect to draw pension. Some numbers help:
- At age 61 the monthly cuts add up to the lump sum in about 8 years 3 months, ignoring interest. The cut then continues until restoration at 15 years.
- Seen as a loan repaid by 180 monthly cuts, commuting at 61 works out at about 9.0% a year. You can compare that with the interest on a loan you would repay with the money, or with what the money could earn safely.
- The lump sum is tax-free for government pensioners, the cut stops if the pensioner dies (the family repays nothing), and family pension is unaffected.
This calculator does not give advice. Your pension office or a financial adviser can help you decide. For the tax side, read tax on gratuity, leave encashment and commuted pension.

Frequently asked questions
How much pension can I commute?
Up to 40% of your basic pension. You can choose a smaller percentage. Dearness Relief is never commuted.
When is commuted pension restored?
After 15 years, counted from the day your pension was first cut, which is the day the lump sum was paid. From then on, the full basic pension is paid again, with Dearness Relief on it as before. Pensioners' bodies have asked for a shorter period, but the 15-year rule has not changed, and courts have upheld it.
Is Dearness Relief paid on the commuted part?
Yes. DR is calculated on the full basic pension before commutation, so commuting does not reduce your DR.
Is the commutation lump sum taxable?
Not for central or state government pensioners: the commuted value is fully exempt from income tax. The monthly pension you keep is taxed as salary.
Does commutation reduce family pension?
No. Family pension is worked out on the last pay drawn, without any cut for commutation.
