This tool helps you calculate the monthly income you’ll receive from your pension annuity.

## How to Use the Pension Annuity Calculator

## How It Calculates the Result

The calculator uses a compound interest formula with additional contributions to determine the future value of your pension annuity:

`Future Value = P*(1 + r)^n + PMT * (((1 + r)^n - 1) / r)`

Where:

- P is the initial amount
- PMT is the annual contribution
- r is the annual interest rate (as a decimal)
- n is the number of years

## Limitations of the Calculator

Please note that this calculator assumes the interest rate remains constant over time and contributions are made at the end of each period. Additionally, it does not account for taxes, fees, or any other deductions which might influence the actual amount.
