Saving Goal Calculator
A savings goal stops being a wish the moment it becomes a monthly number. Enter the amount you want, what you have already saved, how many months you have and the rate your money earns, and this calculator returns the exact monthly deposit that gets you there on time, plus how much of the goal your deposits cover and how much interest covers. The worked example below, a $10,000 goal with $1,000 already saved over 12 months at 3%, needs $739.74 a month.
Model note: interest is credited on your new monthly deposits only. Your current savings are treated as sitting still, so the deposit it asks for is slightly cautious. Interest is shown before tax, and the Interest Earned line never drops below $0.00.
Quick Answer
To reach a $10,000 goal in 12 months with $1,000 already saved and a 3% rate, save $739.74 a month. Your deposits contribute $8,876.92 of the $9,000 gap and interest covers the remaining $123.08. At a 0% rate the same goal needs the full $750.00 a month, which shows how little a rate does over a single year and how much the timeline matters. Enter your own target above for your number.
Key takeaways
- Monthly deposit = the gap (target minus current savings) run through the sinking-fund formula; at 0% it is just the gap divided by the months.
- Total Contributions plus Interest Earned always add back up to the gap: $8,876.92 + $123.08 = $9,000 in the worked example.
- This tool credits interest on your new deposits only and treats money already saved as sitting still, so its answer leans cautious.
- Time is the strongest lever: the same $10,000 goal over 60 months at 4% from $5,000 needs $678.74 a month, not $739.74.

How to use the saving goal calculator
Four inputs, one monthly number. The results stay hidden until you calculate.
- Enter the target amount: the full price of the goal. The worked example pre-fills $10,000.
- Enter your current savings: whatever is already set aside for this goal. It comes straight off the target.
- Enter the time period in months: count the months until the money is needed. One year is 12, three years is 36.
- Enter the annual interest rate: the rate of the account the deposits will sit in. 3 is pre-filled; use 0 for money earning nothing.
- Click Calculate: the monthly deposit appears as the headline figure, with the total to save, your total contributions, the interest earned and a progress bar showing how far your current savings already take you.
Blank and non-numeric fields read as 0, so a blank current savings simply means starting from nothing. Two cases stop the calculation with the message “Please enter valid values”: a target of zero or less, and a time period of zero or less. Everything else runs, including the odd cases covered honestly below, such as already having saved more than the target.
The saving goal formula: a sinking fund on the gap
The calculator first finds the gap, then asks what level monthly deposit, growing at the monthly rate, fills exactly that gap by the deadline. That is the classic sinking-fund payment formula, the same structure published by the SEC’s Investor.gov compound interest calculator for the growth of regular deposits.
Monthly deposit = gap × r ÷ ((1 + r)n − 1), where r = annual rate ÷ 100 ÷ 12 and n = months
At a 0% rate: monthly deposit = gap ÷ n
Total contributions = monthly deposit × n | Interest earned = gap − total contributions
Read the interest line carefully: because the deposit is solved against the gap alone, “interest earned” is exactly the part of the gap your deposits do not have to cover. Contributions plus interest always equal the gap, which makes the output easy to audit: if the two lines do not add up to the Total to Save, something was typed wrong. Deposits are treated as landing at the end of each month, the ordinary annuity convention.
Worked example: $10,000 in a year, starting from $1,000
The pre-filled values are a $10,000 target, $1,000 already saved, 12 months and a 3% annual rate. Running them gives a $9,000 gap, a $739.74 monthly deposit, $8,876.92 of contributions and $123.08 of interest.
Where the $10,000 goal actually comes from, at the end of the year:
The interest slice is thin because the balance is small for most of the year: the first deposit only compounds for eleven months and the last one barely at all. Five more real runs of this calculator show how the number moves:
| Goal | Target | Saved | Months | Rate | Monthly | Interest |
|---|---|---|---|---|---|---|
| Worked example | $10,000 | $1,000 | 12 | 3% | $739.74 | $123.08 |
| Emergency cushion, no interest | $6,000 | $500 | 12 | 0% | $458.33 | $0.00 |
| House deposit, five years | $50,000 | $5,000 | 60 | 4% | $678.74 | $4,275.39 |
| Car in two years | $20,000 | $2,000 | 24 | 12% | $667.32 | $1,984.26 |
| Round target, no head start | $12,000 | $0 | 12 | 0% | $1,000.00 | $0.00 |
The honest boundary: your current savings do not grow here
This tool treats the money you have already saved as sitting still. Only the new monthly deposits earn the rate you enter. That is a modelling choice, it is disclosed rather than hidden, and it is worth understanding before you compare answers across sites.
Fuller models on some rival pages grow the current balance as well, solving for the deposit after subtracting what the existing savings will become. For the worked example that fuller model asks for roughly $737 a month instead of $739.74, because the $1,000 would itself earn about $30 over the year. The difference is small on short timelines and grows on long ones. This tool’s answer is the cautious one: if your current savings do earn interest, you will arrive slightly ahead of plan. What you should not do is mix the two models, entering a rate here and then also counting the growth of your current balance in your head. Pick one accounting and stick to it.
Two edge cases follow from the same code and are also left exactly as the tool behaves. If your current savings already exceed the target, the monthly figure comes out negative (a $5,000 target with $8,000 saved shows $-246.58 a month and a progress bar past 100%): read that as “goal already covered”, not as an instruction to withdraw money. And if you enter a negative rate, the deposit correctly rises ($756.90 for the worked example at −2%), but the Interest Earned line is floored at $0.00 rather than showing a negative figure, even though contributions then total $9,082.80 against a $9,000 gap. Trust the deposit; the interest line is display-clamped.
What competing calculators miss
Savings goal tools tend to pick one simplification and stay quiet about it. The honest differences matter more than the features:
- No-interest tools (CalcAsk, ToolXone): clean (goal − current) ÷ months math, and CalcAsk’s $6,000-from-$500 example correctly returns $458.33, which this calculator reproduces exactly at a 0% rate. The gap: no rate input at all, so a five-year goal in a 4% account gets the same answer as cash in a drawer.
- Same-formula tools (CalcMaster): publishes the identical sinking-fund formula this tool uses, which is reassuring. Its own worked example, however, quotes about $688 a month for $50,000 in 5 years at 4% from $5,000, while its formula (and this calculator) produce $678.74. The example number, not the formula, is off by roughly $9.
- Full-growth models (EasyUnitConverter, Clandrix): grow the current savings inside the formula, a legitimate method that returns a slightly smaller deposit. The gap: neither flags the method choice, so their answers look like disagreements with this page when they are really different accounting.
- Live-rate tools (MonitorBankRates, PointsFrog): anchor the rate to today’s FDIC national average (0.37% in the September 2026 release) or state high-yield averages. Useful context, but the rate is chosen for you and drifts daily, so the answer cannot be reproduced next week.
- The gap this page fills: the standard sinking-fund answer with the split between your deposits and interest printed on every result, the no-growth choice for current savings stated on the page, and the negative-result quirks explained instead of quietly patched.
Picking an honest rate, and where goal money should sit
The rate to enter is the rate of the account the money will actually sit in, not the return you hope for. According to the FDIC’s published national rate data, the average savings account pays well under 1%, while a high-yield savings calculator shows what several percent does to the same deposits. For a goal with a hard deadline, a high-yield savings account is the usual home: the principal cannot fall, the rate is known, and the deposit this calculator asks for stays believable.
Goal type still matters. An emergency fund, the first goal the CFPB’s emergency fund guide walks through, belongs in instant-access savings even at a modest rate, sized at a few months of essential expenses. A house deposit five years out can tolerate a slightly longer product. Retirement money is a different problem again, because at the far end it becomes withdrawals, which the savings distribution calculator handles. And note that bank interest is taxable income: the IRS explains in its Form 1099-INT guidance that interest of $10 or more is reported to you and to them, so the Interest Earned line here is a before-tax figure.
Short on the monthly number? The levers, in order of power, are more months, a smaller target, a bigger starting lump, and only then a better rate. Stretching the worked example from 12 to 24 months cuts the deposit far more than hunting for an extra percent of yield, a pattern the daily savings calculator makes vivid by breaking the same habit down to a per-day figure.
Frequently asked questions
The calculator subtracts your current savings from the target, then divides what is left across the months using the sinking-fund formula: monthly = (target − current) × r ÷ ((1 + r)^n − 1), where r is the annual rate divided by 100 and by 12. At a 0% rate it is simply the gap divided by the months.
Monthly Savings Required is the deposit that reaches the target on time. Total to Save is the gap between the target and your current savings. Total Contributions is the monthly amount times the months. Interest Earned is the part of the gap the rate covers, which is why contributions plus interest always equal the gap.
No, and that is a deliberate, conservative choice in this tool: only your new monthly contributions earn the rate you enter, and your current savings are treated as sitting still. Models that also grow the current balance ask for a slightly smaller monthly deposit.
The math still runs and returns a negative monthly amount: a $5,000 target with $8,000 saved over 12 months at 3% shows $-246.58. Read a negative result as “goal already covered”; you do not need to save anything more toward it.
The rate of the account the money will actually sit in. The FDIC’s national average savings rate has recently been under half a percent, while high-yield savings accounts have paid several percent. For a goal you cannot afford to miss, a cash savings rate is the honest input; a stock market return is a hope, not a rate.
Because the interest line is floored at zero. At −2% the monthly deposit rises to $756.90 and contributions reach $9,082.80 for a $9,000 gap, but the Interest Earned line shows $0.00 instead of a negative figure. The deposit number is the one to trust.
Usually yes. The IRS treats bank interest as ordinary income, and a bank that pays you $10 or more in a year reports it on Form 1099-INT. This calculator shows interest before tax, so the after-tax help toward a goal is slightly smaller than the Interest Earned line.
Raise the monthly amount, start from a bigger lump sum, or give the goal more months: stretching a timeline cuts the required deposit sharply, because both the division and the compounding work in your favour. A higher rate helps least over short timelines.
