How Compound Interest Works

Understanding compound interest is key to building wealth. Learn how it works and how you can take advantage of this powerful financial concept.

What is Compound Interest?

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. It's often referred to as "interest on interest."

Time is Your Greatest Asset

The longer your money is invested, the more time it has to grow. Even small contributions can turn into significant sums over time due to the power of compounding.

How to Maximize Returns

Start investing early, contribute regularly, reinvest your earnings, and take advantage of tax-advantaged accounts to maximize the benefits of compound interest.

The Compound Interest Formula

A = P(1 + r/n)^(nt) + PMT × {[(1 + r/n)^(nt) - 1] / (r/n)} × (1 + r/n)

A

Future Value of the Investment

P

Principal Investment Amount

r

Annual Interest Rate (decimal)

n

Number of Times Interest Compounded Per Year

t

Time the Money is Invested For (years)

PMT

Monthly Contribution

This formula calculates the future value of an investment including both the initial principal and any accumulated interest. The formula takes into account the frequency of compounding, the interest rate, the time period, and any regular contributions.

The first part of the formula, P(1 + r/n)^(nt), calculates the future value of the initial principal. The second part, PMT × {[(1 + r/n)^(nt) - 1] / (r/n)} × (1 + r/n), calculates the future value of regular contributions.

Using our calculator, you can easily determine how your investment will grow over time by inputting your initial investment, monthly contributions, interest rate, compounding frequency, and investment time period.
