Savings Goal Calculator
Find how long it takes to reach a savings target, or the monthly amount you need to hit it by a deadline.
Calculate
Your goal
Calculated in your browser as you type. Nothing is uploaded.
Reaching or passing the goal ends the count. Assumes steady deposits at the end of each month and a constant return.

How to calculate a savings goal
Enter your goal
Type the amount you are saving toward and how much you have set aside already.
Add a return
Enter the annual return you expect on the balance, or leave it at zero for plain saving.
Pick what to solve
Choose time to reach the goal and set a monthly amount, or choose the monthly amount and set a deadline.
Read the result
The finish line, total contributed, and interest earned update instantly, with a year-by-year table below.
Why use this tool
Two questions, one tool
Solve for the time to reach a goal from a fixed monthly amount, or the monthly amount needed to hit a deadline. Switch between the two with a single toggle.
Compounding built in
The balance grows each month at the return you set, so interest earned starts earning too. The result separates what you contributed from what compounding added.
Year-by-year breakdown
A scrollable table shows the contributed total, interest earned, and running balance at the end of every year until the goal is met.
Honest edge cases
If your current savings already meet the goal, or grow past it before the deadline, the calculator says so instead of showing a misleading zero.
Runs entirely in your browser
Everything is calculated on your device as you type; nothing is uploaded and there is no signup.
About this tool
A savings goal calculator answers the two questions people actually have about a target: how long will it take, and how much do I need to set aside. Enter the goal, what you have saved so far, an expected annual return, and either a monthly contribution or a deadline. The tool grows the balance month by month with compounding and reports the finish line, the total you put in, and the interest earned along the way.
Switch between the two modes at the top. In time mode you fix a monthly amount and see how many years and months it takes to cross the goal, with the exact balance the month you get there. In deadline mode you fix a date and the calculator solves for the monthly deposit that lands you on the target, rounded up to the nearest cent so a rounding error never leaves you short. A year-by-year table shows the running split between contributions and interest, so the effect of compounding is visible rather than hidden inside one number.
Use it to sanity check a house deposit, an emergency fund, or any medium term target where regular saving does the heavy lifting. It works in plain numbers, so the result is in whatever currency you type, and it assumes a steady rate and unbroken deposits, so treat the output as a plan to compare against rather than a guarantee. For the pure growth side without a target, the compound interest calculator projects a balance forward, and the loan calculator works the same math in reverse for money you owe. Everything runs in your browser and nothing is uploaded.
Frequently asked questions
- How does the savings goal calculator work?
- It grows your current savings and each monthly deposit forward one month at a time, adding the return you set and then the deposit at the end of the month. In time mode it counts the months until the balance crosses your goal; in deadline mode it solves for the monthly deposit that lands on the goal by your date.
- How is the required monthly contribution worked out?
- From your goal, current savings, return, and deadline, the calculator finds the deposit whose compounded value plus the growth of your starting balance equals the goal. It rounds that figure up to the nearest cent, so rounding never leaves you a little short of the target.
- What if I already have enough saved?
- If your current savings already meet the goal, the calculator tells you the goal is reached rather than showing zero. In deadline mode, if your starting balance grows past the goal on its own before the date, it reports that no monthly contribution is needed.
- Which currency does it use?
- None in particular. The calculator works in plain numbers, so the result is in whatever currency you type. Values are formatted with thousands separators and two decimals but no currency symbol.
- How accurate is the projection?
- It assumes one constant annual return and unbroken deposits for the whole period, with interest compounded monthly. Real returns vary year to year and can be negative, so use the result to compare plans, not as a guarantee. Horizons longer than 100 years are treated as out of reach.
- Is my data uploaded anywhere?
- No. Everything runs in your browser; nothing is sent to a server.
