What Is an Annuity Income Calculator?
An annuity income calculator computes the exact monthly or annual pension you receive when investing a lump sum retirement corpus into an annuity policy.
When retiring in India, investors convert accumulated wealth from the National Pension System (NPS), EPF, or mutual funds into guaranteed lifetime income through insurance providers like LIC of India, HDFC Life, ICICI Prudential, and SBI Life.
This calculator factors in annuity option types (Life Annuity vs Return of Purchase Price vs Joint Life), payout frequencies, and deferment periods to project guaranteed regular income.
Annuity Pension Calculation Formula
Annuity payouts are calculated based on the purchase price and the prevailing headline annuity rate offered by the life insurance company at the time of policy purchase.
Annual Pension Formula
Annual Pension = Purchase Price × (Effective Annuity Rate / 100)Monthly Pension Formula
Monthly Pension = Annual Pension / 12Worked example: Rs 1 Crore corpus invested at 7.0% annuity rate with Return of Purchase Price (0.95x option adjustment = 6.65% effective):
Immediate vs Deferred Annuity Plans
Immediate annuity plans begin paying monthly income immediately upon policy inception. Deferred annuity plans allow your corpus to compound during a 1 to 10 year deferment window before monthly income commences.
| Feature | Immediate Annuity | Deferred Annuity |
|---|---|---|
| Income Start Date | Next month after payment | After 1 to 10 years deferment |
| Ideal Target Audience | People retiring today (Age 60) | Early retirement planners (Age 45-55) |
| Annuity Rate Benefit | Rate locked at purchase | Higher rate due to compounding |
Income Tax on Pension Annuities in India
Unlike SWP withdrawals from equity mutual funds which enjoy LTCG tax relief, monthly annuity income received from life insurance companies or NPS is classified as Income from Other Sources under the Income Tax Act.
Annuity payouts are added to your total annual taxable income and taxed at your applicable slab rate under both the Old Tax Regime and New Tax Regime.
