Saving for a house down payment, a car, a wedding, or just a number that makes you feel safe? Answer either question: how long will it take at my pace — or how much per month to hit my deadline?

Assumes monthly compounding at the stated APY with deposits at the end of each month. For goals under ~2 years, the APY barely matters — consistency does.
It works in two directions. "How long will it take?" mode takes your goal, current savings, and monthly amount and projects the months until you arrive, with interest compounding along the way. "How much per month?" mode flips it: give it a deadline and it solves for the exact monthly deposit required, using the standard future-value annuity formula.
For goals under about two years, APY barely moves the needle; showing up every month does. For longer goals, parking the money at 4%+ instead of 0.01% shaves real months off the timeline — compare rates' effect with the savings interest calculator. If your goal has a fixed far-off date, a CD ladder can lock rates for the whole journey.
Whatever monthly number the calculator gives you, automate it — a standing transfer the day after payday. Goals fail in the gap between intention and transfer, not in the math. And don't raid your emergency fund to hit a goal faster; they serve different jobs.
Saving $400/month at a 4% APY, about 24 months from zero. At $250/month, about 38 months. Enter your own numbers above — a starting balance or higher APY shortens the timeline.
Work backwards from the goal: target amount ÷ months to deadline, minus what interest contributes. The 'How much per month?' mode computes it exactly. A common budgeting anchor is 20% of take-home pay toward savings overall.
Yes for multi-year goals — at 4%+ APY, interest can cover a meaningful slice of the target. For short goals, treat interest as a bonus and plan on deposits alone.
For goals within ~5 years, insured cash: a high-yield savings account, or CDs matched to the goal date if you won't need it early. Money for goals further out than that is where investing conversations start.
