What is Interest Rate Formula?
- The interest rate formula is used to calculate the amount of money that must be repaid on a loan as well as the interest earned on fixed deposits, mutual funds, and other investments.

- The following formula can be used to calculate the compound interest rate for a given amount:
- Compound Interest Rate = P (1+i)t –P
Interest Rate Formula
- In terms of simple interest, the interest rate formula is:
- Interest Rate = (Simple Interest × 100)/(Principal × Time)
- In terms of compound interest, the interest rate formula is:
- Compound Interest Rate = P (1 + i)t –P
- Here,
- P = principal amount
- i = r = rate of interest
- t = time period
