Compound Interest Calculator

Interest growth with flexible compounding frequency.

The Power of Compound Interest

Calculate compound interest wealth growth across flexible compounding frequencies including monthly, quarterly, or annual schedules.

Compound Interest Formula

A = P × (1 + r/n)^(n×t)

Where: A is maturity amount; P is principal; r is annual interest rate; n is compounding frequency per year; and t is tenure in years.

How Compounding Frequency Accelerates Growth

More frequent compounding periods (e.g. monthly vs annually) add earned interest back into the principal faster, resulting in higher effective annual yields.

Simple vs Compound Interest Comparison

Simple interest calculates returns strictly on original principal, whereas compound interest earns interest on previous interest accumulations, yielding exponential growth.

The Rule of 72 for Estimating Money Doubling

Divide 72 by your annual compound interest rate to quickly approximate how many years it will take to double your initial capital investment.

Frequently Asked Questions (FAQ)

What is compounding frequency?

It refers to how often earned interest is credited to the principal balance (e.g., daily, monthly, quarterly, or annually).

Why does monthly compounding yield more than annual compounding?

Monthly compounding reinvests earned interest 12 times a year, increasing the principal base on which subsequent interest is calculated.

How do I calculate compound interest maturity?

Input your principal amount, rate of return, tenure, and compounding frequency into our tool to view principal vs interest breakdowns.
