Compound Interest Calculator

How It Works:

A Compound Interest Calculator helps you calculate the interest earned on an initial amount of money, where the interest is added to the principal periodically. Here’s how it works:

This tool purpose is only for mathematical calculation and education.

  1. Inputs:
  • Principal (P): The initial amount of money you invest.
  • Rate (R): The annual interest rate (as a percentage).
  • Time (T): The time the money is invested for, in years.
  • Compounds Per Year (n): How often the interest is compounded (e.g., annually, monthly).
  1. Formula:
    The compound interest formula used is [A = P × (1 + r/n)^(n × t)]
    where:
  • A = Total amount after interest
  • P = Principal amount
  • r = Interest rate (decimal form, so divide by 100)
  • n = Number of times interest is compounded per year
  • t = Time period in years

Compound Interest is then calculated as: A – P

  1. Result:
    The calculator will show both the Compound Interest and the Total Amount (Principal + Interest).
