Frequently asked questions

What is the compound interest formula?

A = P × (1 + r/n)^(n × t), where P is the principal, r the yearly rate as a decimal, n the number of times interest is compounded per year and t the time in years. Compound interest = A − P.

How is compound interest different from simple interest?

Simple interest is earned only on the original amount. Compound interest is also earned on interest already added, so money grows faster over time.

Does more frequent compounding give more interest?

Yes, slightly. Monthly or daily compounding earns a bit more than yearly compounding at the same rate.

Can I enter part years?

Yes. You can enter time like 2.5 years.

Can I use this for loans too?

Yes, it shows how much a debt would grow if no payments were made. For loans with monthly EMIs, use our EMI Calculator.
