Frequently Asked Questions
What is compound interest?
Compound interest is the interest on your deposit, plus the interest on the interest you've already earned. It enables your money to grow exponentially.
How often should I compound?
Most savings accounts compound monthly or daily. Investment market returns are often calculated annually. The more frequent the compounding, the higher the return.
Does this account for inflation?
This calculator shows the nominal future value. To account for inflation, you can subtract the inflation rate from your expected interest rate.
What is a good interest rate to use?
The historical average return of the stock market (S&P 500) is about 7-10% annually. High-yield savings accounts might offer 4-5%.
Is the formula accurate?
Yes, we use the standard financial formula: A = P(1 + r/n)^(nt). For contributions, we assume they are made at the end of each compounding period.
