About This Tool
Why use Investment Return Calculator?
US banks advertise savings returns as APY (annual percentage yield), which already includes the effect of compounding. High-yield savings accounts, CDs and money market accounts at FDIC-insured banks are covered up to $250,000 per depositor, per insured bank, for each account ownership category.
For long-term goals, tax-advantaged accounts such as a 401(k), traditional IRA or Roth IRA can matter as much as the rate itself, because growth is tax-deferred or tax-free. Interest earned in a regular savings account is taxed as ordinary income, and investment returns in the stock market are not guaranteed, so model a range of rates rather than a single optimistic one.

Investment Return Calculator FAQs
What is the difference between APY and APR on savings?
APR is the simple annual rate, while APY includes compounding within the year. For savings, APY is the figure to compare because it shows what you actually earn over a year.
Is my money insured in a US savings account?
Deposits at FDIC-insured banks are protected up to $250,000 per depositor, per insured bank, for each account ownership category. Credit unions have similar coverage through the NCUA. Investments such as stocks and mutual funds are not deposit-insured.
What return should I assume for long-term investing?
No return is guaranteed. Many people test a conservative figure and a more optimistic one, then plan around the lower result. Remember that inflation reduces the real value of future balances.
Is interest on savings taxable in the US?
Yes. Interest from ordinary savings accounts and CDs is generally taxed as ordinary income in the year it is earned. Growth inside a 401(k) or IRA is tax-deferred, and qualified Roth withdrawals are tax-free.
Which currency does this investment return use?
Amounts are shown in US Dollars (USD). The formulas are the same everywhere, so you can switch to another country version if you need a different currency.
