Commuted Pension Calculator — Tax-Free Lump Sum

Commuted pension is a one-time lump sum amount that a government employee can receive by surrendering a part of their monthly pension at retirement. Central government employees can commute up to 40% of their monthly pension as a lump sum. Formula: Lump sum = Percentage commuted × Monthly pension × 12 × Commutation factor. The commutation factor is published by the government in actuarial tables based on age at retirement. At age 60, the factor is 8.194. Example: if monthly pension is ₹50,000 and you commute 40%: Commuted amount = 40% × ₹50,000 × 12 × 8.194 = ₹19,66,560. The remaining 60% (₹30,000) continues as monthly pension.

The commutation factors (from official government actuarial tables) for different ages in 2026 are: Age 55 = 11.546, Age 56 = 11.139, Age 57 = 10.722, Age 58 = 10.294, Age 59 = 9.856, Age 60 = 9.407, Age 61 = 8.950, Age 62 = 8.483. These factors represent the present value of ₹1/month pension commuted. A lower factor means less lump sum for the same pension — so commuting at a younger age gives more money. However, you must be very sure about commuting a large portion, as the monthly pension reduces permanently (until restoration at 15 years).

The commuted portion of pension is restored — i.e., added back to the monthly pension — after 15 years from the date of commutation. If you retired at 60 and commuted 40% of your pension, at age 75 your full monthly pension is restored. The restoration is automatic — you don't need to apply. After restoration, you receive the full pension amount that you were getting before commutation. Since DA is calculated on the full pension (not the reduced pension), the DA relief continues to be calculated on the full pension throughout. This is an important benefit.

Yes. For central government, state government, local authority employees, and employees of statutory corporations, commuted pension received is completely exempt from income tax under Section 10(10A)(i) — with no monetary limit. There is no upper ceiling on the tax-free commuted pension amount for government employees. For private sector employees, commuted pension is tax-free only up to one-third of the total pension (if they receive gratuity) or half of the pension (if no gratuity). After restoration of commuted pension at 15 years, the monthly pension received is taxable as income.

Whether to commute pension or not depends on your financial situation and life expectancy. Arguments for commuting: you get a large lump sum immediately (tax-free), useful if you have debts, home loan, or need capital; you can invest the lump sum and potentially earn more than the pension foregone. Arguments against commuting: you permanently reduce monthly income for 15 years; the break-even (when cumulative pension foregone equals lump sum received) is usually around 10-12 years — so if you live 15+ years post-retirement, not commuting is better financially. Many financial planners suggest commuting only 20-25%, not the full 40%, to balance both lump sum and monthly income.
