Savings Goal Calculator — How Long to Save
The fixed-budget view: instead of asking what to save, you tell it what you can save and it solves the timeline. Depositing $520 a month toward $20,000 from a $2,000 start at 4% APY takes 33 months — about 2.8 years. It is the right direction to solve when the monthly amount is the hard constraint and the date is flexible, and it reports honestly when a plan never gets there.

Breakdown
Solves the deposit or timeline from the goal, balance, and APY you enter, compounding monthly. Savings rates change over time, so treat the result as a planning estimate — not financial advice or a rate offer.
When the budget is fixed and the date floats
The simulation deposits your amount monthly, compounds the balance, and counts months until the goal is crossed. Timelines respond sharply to the deposit: at $400 a month the same $20,000 goal takes about 42 months, at $520 it takes 33, and at $700 it drops near 25. Seeing the curve makes the trade between lifestyle and deadline concrete.
One edge case matters: with no deposit and no interest the goal is unreachable, and the calculator says so rather than returning a fake timeline. The practical floor for any plan is a deposit that meaningfully outpaces what you expect from interest alone.
Questions
- How long does $20,000 take at $520 a month?
- From a $2,000 starting balance at 4% APY, 33 months — roughly 2.8 years, with $17,160 of deposits and about $1,180 of interest.
- Why does the result jump in whole months?
- Deposits land monthly, so the calculator reports the first month-end at which the balance crosses the goal rather than interpolating a partial month.
