About this digital tool
The savings goal calculator tells you how long it will take to reach a target amount, for example a house deposit, a car or a trip. Enter the target amount, what you already have, how much you save each month and the interest rate, and the tool calculates the number of months or years needed, splitting the total between your own money and the interest earned.
The calculation uses monthly compounding, so the earlier you start, the more the interest works for you. You can also use it in reverse: try different monthly amounts to see how the time shortens. The result is an estimate, because bank rates and inflation change over time.
How to use
- Enter the amount you want to reach and how much you have saved so far.
- Enter how much you will deposit each month and the annual interest rate.
- See the time needed and the split between your contribution and interest.
Frequently asked questions
How is the time to reach the goal calculated?
Each month, monthly interest (annual rate ÷ 12) is added to the balance and then the monthly deposit, until the target amount is reached.
Does it take interest into account?
Yes. If you enter an interest rate, the calculator compounds it monthly; if you leave it at 0, it counts only your savings.
How much should I save each month to reach a goal?
Divide the target amount by the months you have available, then subtract the expected interest. In the calculator, enter the monthly amount and see how many months it takes; adjust until the timeline suits you.
Does interest affect the savings time?
Yes. With a positive rate, the interest portion reduces the number of months needed, especially over a long period. At a 0% rate the calculation is simply division.
Why can the result differ from reality?
Because interest rates, inflation and the amount you actually save change in practice. Treat the result as a guide and recalculate from time to time.
