Frequently Asked Questions

What interest rate should I use?
Use the APY (Annual Percentage Yield) advertised by your savings account or HYSA. As of 2025, high-yield savings accounts typically offer 4–5% APY. For investments, a 6–8% long-run average is commonly used.
Why does the time change so much when I adjust the rate?
Compound interest is exponential. A higher rate means your balance grows faster each month, dramatically shortening the time to reach your goal, especially for larger targets over longer periods.
What if I want to know how much to save each month?
Try adjusting the monthly contribution until the time-to-goal matches your target date. This effectively solves for the required monthly deposit.
