Introduction
Compound interest lets your savings grow quicker since you earn interest on interest. Our calculator helps you see how much your investments could grow over time. Plan for retirement, education, or just see how wealth builds with quick, precise estimates.
What Is Compound Interest?
Compound interest means earning interest on your initial money plus the interest it has already earned. So, your money grows faster than with simple interest, which only pays interest on the starting amount.
For instance, if you put $1,000 in an account with a 10% annual interest rate, you’d get $100 after a year. In the second year, though, you’d earn interest on $1,100, not just the original $1,000. That’s the beauty of compounding!
How the Compound Interest Calculator Works
Our Compound Interest Calculator uses this formula: A = P (1 + r/n) ^ (n × t)
Here’s what each part means:
A = Final amount
P = Starting amount
r = Yearly interest rate
n = Times interest is added per year
t = Number of years
Just put in your starting amount, interest rate, how often it compounds, and the time and you’ll quickly see your total and interest earned.
