Compound interest is probably the most smartest investment you can come up with because you make your investment compound. Whether you're planning for home loans, car loans, or investments like fixed deposits, understanding compound interest is crucial. This calculator helps you determine returns using principal, interest rate, compound rate and time-of-compounding.
What is a Compound Interest Calculator?
A compound interest calculator is an online financial tool that computes the future value of an investment. It calculates the compound interest accrued over time, based on user inputs like principal, rate of interest, time period, and compounding frequency (annually, semi-annually, quarterly, or monthly). Unlike simple interest where interest is calculated only on the principal amount, compound interest generates returns on both principal and accumulated interest.

How Does Compound Interest Work?
Compounded interest pays you back with earned interest so the interest grows in real terms. Compound interest is:
A = P (1 + r/n)^(nt)
- A: Maturity Amount
- P: Principal Amount
- r: Annual Interest Rate (in decimal)
- n: Number of Compounding Periods per Year
- t: Time in Years

| 10,000 | 5 | 10 | Quarterly | 16,470.09 |
