What is a Compound Interest Calculator?
A Compound Interest Calculator is a financial tool used to determine how much interest will accumulate on an investment or loan over time, taking into account the effects of compounding. Unlike simple interest, which is calculated only on the principal amount, compound interest grows on the principal as well as the interest already earned.
How Does a Compound Interest Calculator Work?
Compound interest calculators work by applying the formula for compound interest to your input data. By entering your initial investment amount, annual interest rate, and compounding frequency, the calculator computes how much your investment will grow over a specified period.
Formula for Compound Interest Calculation
The formula for calculating compound interest is:
[ \text{Compound Interest} = P \left(1 + \frac{r}{n}\right)^{n \times t} – P ]
where:
- ( P ) is the principal amount,
- ( r ) is the annual interest rate (decimal),
- ( n ) is the number of times interest is compounded per year,
- ( t ) is the time in years.
Types of Interest Calculations
- Simple Interest: Calculated only on the principal amount using the formula:
[ \text{Simple Interest} = P \times R \times T ]
where ( P ) is the principal, ( R ) is the rate, and ( T ) is the time. - Compound Interest: Calculated on both the principal and accumulated interest using the compound interest formula.
- EMI Interest: Used for calculating monthly payments on loans. The formula is:
[ EMI = \frac{P \times r \times (1 + r)^n}{(1 + r)^n – 1} ]
where ( P ) is the loan amount, ( r ) is the monthly interest rate, and ( n ) is the number of months.
