The formula, without interest
Monthly savings = (goal − what you have) ÷ months. It’s the right sum for most short-term goals, because over a few months interest changes little.
| Item | Value |
|---|---|
| Goal | $10,000 |
| Already saved | $1,000 |
| Still needed | $9,000 |
| Time | 12 months (1 year) |
| Monthly savings | $750 |
With interest: let your money work too
If you keep your savings somewhere that pays interest, you need a little less each month. In the example, at 4% APY you set aside $733.32 a month: you put in $9,799.84 and interest adds about $200.19. The calculator uses the effective annual rate (the APY most savings accounts show); if you only have a nominal rate, convert it with the compound interest calculator.
How long will it take?
Sometimes you don’t have a deadline but an amount that fits your budget. With $500 a month, starting from $1,000 and the same rate, you reach $10,000 in 18 months (1 year and 6 months) (ending with $10,315.46). Pick “How much I can save a month” in the calculator to run this one.
Typical goals and how much to set aside
| Goal | Amount | Time | Per month |
|---|---|---|---|
| Emergency fund (3 months of $2,500 expenses) | $7,500 | 18 months (1 year and 6 months) | $416.67 |
| Vacation | $3,000 | 10 months | $300 |
| Car down payment | $5,000 | 24 months (2 years) | $208.34 |
| New laptop | $1,200 | 6 months | $200 |
The emergency fund comes first: 3 to 6 months of your essential expenses, so a surprise doesn’t turn into debt.
How to hit your goal
- Save as soon as you get paid, not what’s left at the end of the month: there’s rarely anything left.
- Keep it separate, in another account, so you don’t spend it by accident.
- Automate it: a scheduled transfer on payday.
- If it’s hard to get going, try the 52-week savings challenge or split your paycheck with the 50/30/20 rule.

Frequently asked questions
What rate should I enter if I don’t know what I earn?
Leave it at 0. The calculator then tells you what to set aside without counting on interest, which is the safest option. If you later keep the money in an account that pays, you’ll get there a little sooner.
What if the monthly amount is too much for me?
You have three levers: a longer deadline, a smaller goal, or starting with something you already have. Try “How much I can save a month” with what really fits your budget and see how long it takes.
Where should I keep the money for a goal?
Apart from your everyday account, so you don’t spend it without noticing. For short-term goals a savings account or a deposit you can withdraw in time works well; avoid risking money you’ll need in a few months.
Does inflation change my goal?
Yes. If the goal is to buy something a year or more from now, it will probably cost more. Add what you think the price will rise to your goal, or review it every few months.
