Savings Goal Calculator — How Long to Reach Your Target
Enter your goal, what you’ve saved so far, how much you add each month, and an expected annual return. CalcWize compounds the balance month by month and shows how long until you hit the target, how much you contributed, and how much the growth added on top.
Contribution does the heavy lifting
For short and medium goals, the monthly amount you save matters far more than the return rate — there isn’t enough time for compounding to dominate. For a house deposit a few years out, focus on the monthly number, not on chasing yield.
What return rate to use
For a goal a year or two away, keep the money in cash or a high-interest savings account and use a low rate (or 0). Only goals many years out justify investing for a higher — but riskier — return that could fall just when you need the money.
Reaching it by a deadline
If you have a target date, divide the remaining gap by the months available for a rough required monthly amount, then adjust the contribution here until the time-to-goal matches. Small increases move the date a surprising amount.
Common mistakes
Assuming an optimistic return for a near-term goal; forgetting that contributions, not growth, drive short timelines; and not automating the transfer, so the saving never actually happens.
Frequently asked questions
- How much should I save each month?
- Work back from your goal and deadline: divide the amount still needed by the months you have. The calculator lets you test a monthly figure and see the resulting timeline.
- Should I invest to reach the goal faster?
- Only for goals many years away. For anything within a few years, market swings can leave you short exactly when you need the money — keep near-term savings in cash or a high-interest account.
- Does it account for inflation?
- No — the figures are nominal. For long-term goals, remember the target amount itself may need to rise with inflation.
How we calculate it
The balance compounds monthly at the annual return ÷ 12, with your contribution added each month, until it reaches the goal. Total contributed is the sum of your deposits; interest earned is everything above your starting balance plus contributions.
What it doesn't do
- Tax-advantaged accounts with contribution caps (see the Retirement Planner)
- Variable or market-linked returns (this assumes a steady rate)
- Inflation adjustment — figures are nominal
