What is the Interest Calculator?

An interest calculator helps estimate how money grows or how much interest is payable over time. It can be used for savings, deposits, loans, education examples and comparing simple interest with compound interest.

Simple interest is calculated only on the original principal. Compound interest is calculated on the principal plus accumulated interest, which means the amount can grow faster when interest is compounded over multiple periods.

The calculator is helpful for understanding the effect of principal, rate and time. A small change in rate or duration can produce a noticeable difference, especially when compounding is involved.

How we calculate the result for Interest Calculator India

Formula: Simple Interest = P x R x T / 100; Compound Amount = P x (1 + r/n)^(n x t)

For simple interest, P is principal, R is annual interest rate and T is time in years. The interest is added once and does not earn additional interest.

For compound interest, r is the annual rate in decimal form, n is the number of compounding periods per year and t is time in years. More frequent compounding can increase the maturity amount because interest is added to the principal more often.
