What Is Compound Interest?

With compound interest, earned interest is added back to the principal each period. This snowball effect means that even small regular contributions can grow significantly over time.

Formula

Monthly rate = Annual rate ÷ 12
Monthly PMT = FV × r ÷ ((1+r)^n − 1)

r = monthly rate, n = months

常见问题

What if I enter 0% interest?

With 0% interest the tool uses simple division: Monthly = Goal / Months. Total equals deposited amount since no interest is earned.

Which interest rate should I use?

Enter the annual gross rate. Taxes and fees will reduce your net return. Using the net annual yield of your savings account gives the most realistic result.

Can I adjust for inflation?

To account for inflation, use the real rate: Real rate = ((1 + nominal) / (1 + inflation)) - 1. For example, 6% nominal and 3% inflation gives a real rate of about 2.9%.
