What Is Compound Interest?


Compound interest is the secret ingredient behind long-term wealth building. Unlike simple interest, which only pays you on your original deposit, compound interest rewards you for both your initial investment and all the interest you've already earned. This means your money can grow much faster, especially when you give it time to work its magic.


Why Compound Interest Matters for Your Financial Goals


Whether you're saving for retirement, planning for your child's education, or just looking to grow your savings, compound interest can help you reach your goals faster. The earlier you start, the more you benefit—thanks to the "snowball effect" of earning interest on interest.


Did You Know?


  • Monthly compounding grows your money faster than annual compounding.
  • Even a small increase in your interest rate or investment period can make a big difference in your future value.
  • Compound interest works for you in savings—but against you in debt, like credit cards!

Experiment with different values above to see how your money can grow. Our compound interest calculator is designed to help you make smarter financial decisions and visualize your investment growth with confidence.

Frequently Asked Questions

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.
How is compound interest calculated?
Compound interest is calculated using the formula: FV = PV × (1 + r/n)^(nt), where PV is the principal, r is the annual interest rate, n is the number of compounding periods per year, and t is the number of years.
What are common compounding frequencies?
Common compounding frequencies include annually, semi-annually, quarterly, monthly, weekly, and daily. The more frequently interest is compounded, the greater the future value.
Why does compounding frequency matter?
A higher compounding frequency results in interest being calculated and added to the principal more often, which increases the total amount of interest earned over time.
