This tool helps you estimate your annual income from your pension pot.

Pension Pot Annuity Calculator

Use this calculator to estimate your monthly annuity payment from your pension pot. Simply enter the total amount in your pension pot, the expected annual interest rate, and the number of years over which you wish to receive payouts.

How It Works

The calculator uses the following formula to compute the monthly annuity payment: [PMT = P times frac{r(1 + r)^n}{(1 + r)^n – 1}]


  • P is the principal amount or the pension pot
  • r is the monthly interest rate (annual interest rate divided by 12)
  • n is the total number of payments (years multiplied by 12)

After calculating the monthly payment, the result is displayed in the “Result” field.

How to Use It

  1. Enter the total amount of your pension pot in the “Pension Pot Amount (£)” field.
  2. Enter the expected annual interest rate in the “Annual Interest Rate (%)” field.
  3. Enter the number of years over which you wish to receive the payments in the “Years to be Paid Out” field.
  4. Click on the “Calculate” button to see the monthly annuity payment in the “Result” field.


This calculator provides an estimate only. The actual annuity payments you receive may vary based on changes in the interest rate, fees, taxes, and other factors not accounted for by this calculator. It is recommended to consult with a financial advisor for precise planning.
