Frequently Asked Questions
What is compounding frequency?
It's simply how often the interest is added to your account. This could be daily, monthly, or once a year. The more often it's added, the faster your money grows, because you start earning interest on your new interest right away.
Why is compounding so powerful?
Compounding is powerful because it helps your money grow faster over time. When you earn interest, that interest gets added to your balance. Then, you earn interest on the larger balance, creating a snowball effect that turns small savings into bigger amounts if left alone.
Does inflation matter?
Yes, inflation means that things cost more over time, so your money might not buy as much in the future. To really grow your wealth, you ideally want your interest rate to be higher than the rate of inflation.
Can I include monthly contributions?
This particular calculator focuses on a starting amount left to grow on its own. However, adding money every month is a great habit, and there are other calculators out there that can help you see how regular deposits speed up your savings growth.
