Savings Goal Calculator
Two ways to plan a savings goal: find the monthly amount that hits a target by a date, or find how long a set monthly amount will take. Both can include interest.
1. How much to save each month
Set a target and a deadline; the calculator works out the monthly amount.
2. How long a fixed amount will take
Set how much you can save each month; the calculator works out the time.
Making the plan stick
- Automate it. Set a standing transfer for the day after payday so the money moves before you can spend it.
- Keep goal money separate. A dedicated account stops it blending into everyday spending.
- Match the account to the timeline. For goals within a couple of years, a high-yield savings account keeps the money safe and liquid. Longer horizons are where people take on investment risk for a higher expected return.
- Revisit after a raise. Increasing the monthly amount when your income rises shortens the timeline sharply.
- Mind inflation. If your goal is years away, the thing you are saving for may cost more by then — build in a margin.
How the maths works
The calculator steps through the goal one month at a time. Each month it adds one twelfth of the yearly interest rate to the balance, then adds your contribution. For plan 1 it solves for the contribution that lands exactly on the goal at the deadline; for plan 2 it counts the months until the balance passes the goal. With a 0% rate this is just the goal minus current savings, divided by time or by the monthly amount.
Frequently asked questions
How much should I save each month to reach my goal?
It depends on the target, how much you already have, how long you have, and any interest earned. Enter those below and the calculator solves for the monthly amount. As a rough check without interest: (goal − current savings) ÷ number of months.
What interest rate should I put in?
For money you will need within two to three years, a high-yield savings account rate is realistic — often somewhere around 3–5% depending on the year and country. For longer goals people often invest and use a lower, more cautious long-run estimate. Use 0% if you just want the plain "divide it up" answer.
Does the calculator assume monthly or yearly compounding?
Monthly. It adds one twelfth of the annual rate to the balance each month, then adds your contribution, and repeats.
Should I build an emergency fund before saving for a goal?
Usually yes. A common approach is to keep three to six months of essential expenses in an easy-access account first, then direct new savings toward specific goals. This tool does not judge priority — it just does the maths for whatever goal you enter.
Why does saving earlier make such a difference?
Money you put in sooner earns returns for longer. With interest, the first contributions do the most work, which is why starting small and early usually beats starting big and late.
