Savings Goal with Interest Calculator
See how compound interest shrinks your monthly savings. Compare the with-interest plan against saving with no growth.
Monthly savings targets are worked out in your browser; your goals and balances never leave your device.Try: Target amount=20000, Already saved=4000, Annual rate=4, Months left=36 → $20,000.00, $4,000.00, 4%, 36, $405.72, $444.44
How to use
Beyond the usual goal, current savings, and months, add a realistic annual rate. The calculator shows what you would save each month if that money compounds, next to the no-growth figure.
Rates vary; a high-yield savings rate is a fair number to try. The gap between the two lines tells you how much growth is doing the work.
FAQ
Why does interest lower my monthly amount?
Money already in the account earns more over time, so each dollar you add grows. That growth covers part of the goal, leaving less for you to contribute.
What rate should I enter?
Use a realistic savings rate — often 1% to 5% a year. The 4% shown is a gentle example; a high-yield account rate is a good stand-in.
Is the "without interest" line useful?
It shows the gap. If interest only saves you a few dollars a month, a no-growth plan may be simpler to think about.
