How compound interest works
Compound growth means that each period's interest is added to the balance, so later interest is calculated on both your deposits and earlier growth. This tool divides the nominal annual rate by 12 to obtain the monthly rate and assumes contributions are made at the end of each month.
What this estimate includes
Enter a starting amount, a regular contribution, an illustrative annual rate and a time period. The result separates the money deposited from the modelled growth so you can compare scenarios clearly.
What it does not predict
Markets and savings rates can change. This calculator does not model withdrawals, account charges, inflation, tax, exchange rates or investment risk. Use it for planning scenarios rather than a promise of performance.
