The method
How it is worked out
FV = P(1+r)N + C × ((1+r)N − 1) ÷ r
- P
- Starting balance
- C
- Monthly saving
- r
- Monthly interest rate
- N
- Months
Savings Calculator
Project a savings balance from a starting amount, regular deposits, interest rate and saving period. The result updates as you type so you can compare scenarios quickly.

- InflationThe balance is shown in nominal future money.
Use the calculator to compare scenarios rather than as a guaranteed forecast.
About the Savings Calculator
Forecast a savings balance when you have an opening amount and expect to add money regularly. It can help you set a contribution target for an emergency fund or compare how a different rate and saving period affect the amount available later.
How it works and an example to tryShow less
How to use the result
Enter the opening balance, regular deposit, assumed annual interest rate and duration. The model accumulates deposits and compounds growth to show the projected total and your own contributions separately. It assumes a steady rate and does not account for withdrawal restrictions, account charges, tax or inflation reducing the future purchasing power of the balance.
Example to try
Try putting 150 a month into a rainy-day fund for three years. Compare the outcome with a smaller contribution rather than choosing an unrealistically high interest assumption. If you have a fixed target, check whether the projected cash balance meets it before considering any tax or fees.

Who uses it, and when
Households building an emergency fund, people saving for a wedding, a car or a deposit, and anyone deciding between a regular-saver account and a lump-sum deposit.
Mistakes worth avoiding
- Setting a monthly amount you cannot sustain and then abandoning the plan.
- Ignoring withdrawal restrictions and bonus rates that fall away after twelve months.
- Measuring the target in today's money while the cost of the goal rises with inflation.
