Savings Goal Calculator
Enter your savings target, current balance, monthly contribution, and expected annual interest rate to see exactly how many months and years it will take to reach your goal, plus how much of the final balance comes from interest.
How this calculation works
Each month your balance grows in two ways: it earns interest on whatever is already saved, and it increases by your fixed monthly contribution. The calculator converts your annual rate to a monthly rate (annual rate ÷ 100 ÷ 12) and applies it every month, then adds your contribution — this is the same compounding logic used by ordinary savings and money-market accounts.
The calculator simply repeats this monthly step until your balance reaches the goal, counting the months as it goes. If your current balance already meets or exceeds the goal, it takes zero months. If your contribution and interest rate are too low to ever close the gap (for example, 0 monthly deposits with 0% interest below the goal), the result is reported as unreachable rather than an absurdly large number.
The interest shown is simply the difference between your final balance and the total cash you put in (starting balance plus every monthly contribution) — it isolates how much growth came from compounding versus your own deposits.
Worked example
Why monthly contributions matter more than interest early on
For most savings goals, the biggest driver of progress is the size and consistency of your monthly contribution, not the interest rate. Interest only starts to meaningfully accelerate growth once your balance is large relative to your monthly deposit — for a two-to-three-year goal, doubling your monthly contribution usually cuts the timeline far more than doubling the interest rate would.
How rate changes the timeline
The table below shows months to reach a 10,000 goal starting from 1,000, saving 300 per month, at different annual rates. Notice how the effect of interest grows as the rate rises, but even a strong rate cannot substitute for a low or zero monthly contribution.
| Annual rate | Months to goal | Interest earned |
|---|---|---|
| 0% | 30 | 0 |
| 2% | 30 | 272 |
| 4% | 29 | 520 |
| 6% | 28 | 742 |
| 8% | 27 | 939 |
Common savings goals and typical targets
- Emergency fund: 3–6 months of essential living expenses, kept in an easily accessible account.
- Down payment: often 10–20% of a home's purchase price, saved over several years.
- Vacation or large purchase: a fixed amount saved over a short, defined window, usually with minimal reliance on interest.
- Wedding or major event: a target set well in advance, often split between a couple's contributions.
- Retirement top-up or sinking fund: smaller recurring goals used to smooth out irregular future expenses.
Tips to reach your goal faster
Automating your monthly contribution removes the temptation to skip a month, which is often the biggest cause of a goal slipping past its target date. Small increases to your monthly deposit — even 10–20% more — compound over time and can shave meaningful time off a multi-year goal.
Keeping goal savings in a high-yield account rather than a standard checking account costs nothing extra to do and, as the table above shows, meaningfully shortens the timeline once your balance builds up.
