Simple Interest Formula
The basic formula for simple interest is:
Simple Interest = (Principal × Rate × Time) / 100
This formula is used when interest is calculated only on the original principal amount.
You can also use our Simple Interest Calculator for dedicated simple interest calculations.
Compound Interest Formula
Compound interest is calculated on both the principal and previously earned interest.
Compound Amount = P (1 + R/100)^T
Where:
P = Principal
R = Rate
T = Time
Compound interest helps your money grow faster over time.

Example of Interest Calculation
Suppose you invest $1,000 at an interest rate of 5% per year for 3 years.
Simple Interest:
(1000 × 5 × 3) / 100 = $150
Total Amount = $1,150
Compound interest would give a slightly higher return.
You can calculate this instantly using our free interest calculator.
