Welcome to our Compound Interest Calculator, the easy-to-use tool that helps you determine how your investments or savings will grow over time. Whether you’re saving for retirement, a big purchase, or simply want to understand the power of compound interest, our calculator makes it easy to estimate your financial future.

What is Compound Interest?

Compound interest is the interest on a loan or deposit that is calculated based on both the initial principal and the accumulated interest from previous periods. Unlike simple interest, compound interest allows your savings to grow faster because the interest earned in one period is added to the principal for the next period, earning interest itself.

In other words, you earn interest on the interest! This is why compound interest is often referred to as the “eighth wonder of the world” for its ability to significantly increase the value of your investments over time.

How Compound Interest Works

Compound interest can be calculated using the following formula:

A = P × (1 + r/n)^nt

Where:

• A is the amount of money accumulated after interest.
• P is the principal amount (the initial investment).
• r is the annual interest rate (decimal).
• n is the number of times interest is compounded per year.
• t is the time the money is invested or borrowed for, in years.

Our online compound interest calculator uses this formula to help you calculate the future value of your investments based on your initial deposit, monthly contributions, annual interest rate, and the frequency of compounding.

Compound Interest FAQ

• What is the difference between simple interest and compound interest?
  Simple interest is calculated only on the principal amount, while compound interest is calculated on both the principal and the accumulated interest.
• How often should I compound my interest?
  The more frequently interest is compounded, the faster your investment will grow. For example, daily compounding typically yields higher returns than monthly or annual compounding.
• What is the best compound frequency for maximizing growth?
  Daily compounding generally provides the highest returns, but monthly or annual compounding might be more realistic depending on the type of investment.
