How to calculate compound interest
UtilNexo's compound interest calculator shows the growth of a value when interest applies to both the capital and the accumulated interest — the famous 'interest on interest'.
The formula is M = C × (1 + i)^t. If you invest $1,000 at 1% per month for 12 months, the amount is 1,000 × (1.01)^12 ≈ $1,126.83.
Compound interest is the basis of long-term investments, financing, and debt correction. The longer the term, the greater the exponential growth effect.
Examples
- 1000; 1; 12 → 1126.83.
- 10000; 10; 3 → 13310.00.
Limitations
- The rate and time must be in the same unit (for example, % per month and months).
- The result does not account for taxes, management fees, or contributions and withdrawals during the period.
How to use the compound interest calculator
- 1Enter the initial capital.
- 2Type the interest rate and the period.
- 3See the final amount.
Frequently asked questions
What is compound interest?
It is interest that applies to both the capital and the already accumulated interest, generating exponential growth.
How do I calculate it manually?
Use M = C × (1 + i)^t, where i is the rate in decimal and t is the number of periods.
Why does the term make such a difference?
Because the exponential effect amplifies gains (or costs) as interest accumulates over time.
