What is Annuity Payout?
The Annuity Payout calculation tells you your annual payout from a few simple inputs. The figure you are solving for here is the annual payout, expressed in INR.
The Annuity Payout formula
The core formula is:
Annual payout = Annuity principal × (Annual interest rate ÷ 100) ÷ (1 - (1 + Annual interest rate ÷ 100)^(-Payout period))Here is what each input means:
- Annuity principal — a money amount. Example: ₹10,00,000.
- Annual interest rate — a percentage, such as an annual rate. Example: 6%.
- Payout period — a value you set on the slider. Example: 20 years.
How to calculate it step by step
- Write down the annuity principal (for example, ₹10,00,000).
- Write down the annual interest rate (for example, 6%).
- Note the payout period (for example, 20 years).
- Apply the formula above to get your annual payout.
- Double-check the result with the Annuity Payout Calculator.

Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
- Annual rates must be converted to the period you are calculating for (for example, divide an annual rate by 12 for a monthly figure).
