Savings Goal Calculator
A savings goal calculator works out the regular amount you need to set aside — each week, month or year — to reach a target by a chosen date, once your starting balance and the interest you earn are counted in. Pick your currency, enter your goal, and see the exact amount to save.
Find how much to save, how long it will take, or how much you’ll have — a savings target, money or financial goal planner that works in any currency.
Works worldwide — USD, GBP, EUR, CAD, AUD, INR and more. Educational estimate, not financial advice.
How the savings goal calculator works
Reaching a savings target comes down to three moving parts: how much you start with, how much you add and how fast it grows. Fix any two and this tool solves for the third, which is why it has three modes:
- How much to save — you know the goal and the deadline; it returns the deposit needed each week, month or year.
- How long it takes — you know what you can put away; it returns when you’ll get there.
- What I’ll have — you set the deposit and the timeframe; it projects the final balance.
Your starting balance is grown forward to the goal date first, so you only ever fund the gap that’s left. Interest is applied at whatever compounding frequency you choose, and the tool converts it to an effective rate for your deposit period — so daily, monthly or yearly compounding are all handled correctly.
Set a goal by a target date — or by age 30, 40 or 50
Most savings goals come with a deadline: a wedding next summer, a house deposit in three years, or a round-number birthday. To plan by a date, enter the years and months between now and then — the calculator returns the exact amount to save each period to arrive on time. Flip to How long it takes and it works the other way, turning an amount you can afford into the date you’ll reach the goal.
The same idea covers age milestones. To see how much to save by 30, 40 or 50, use the years until that birthday as your timeline. As a rough guide, some planners suggest having about 1× your salary saved by 30, 3× by 40 and 6× by 50 — loose benchmarks, not hard targets, so enter your own number and let the tool do the maths.
How much of your income should you save?
A widely used rule of thumb is the 50/30/20 budget: roughly 50% of take-home pay for needs, 30% for wants, and 20% for saving and paying down debt. That makes it a quick way to set a savings goal based on your salary — and it is only a guide, so when you are chasing a specific target, such as a house deposit or an emergency fund, you may deliberately dial saving up for a while and trim the “wants” slice.
Two targets almost everyone benefits from: an emergency fund of about three to six months of essential spending, and then a goal-specific pot on top. Automating the transfer the day you are paid — “pay yourself first” — is the single habit most likely to get you there.
Where to keep your savings
The right home for the money depends on your timeline and where you live:
- United States — a high-yield savings account (HYSA), or a CD for money you will not touch for a set term.
- United Kingdom — a Cash ISA (tax-free interest) or a regular-saver account; Premium Bonds for a no-risk option.
- Canada — a TFSA lets your interest and growth compound tax-free.
- Australia — a high-interest savings account with a bonus rate for regular deposits.
- India — a high-interest savings account, a recurring deposit (RD) for a fixed monthly amount, or a fixed deposit (FD) for a lump sum; a PPF for long-term tax-free growth.
- Germany & the euro area — a Tagesgeld (instant-access) or Festgeld (fixed-term) account.
For goals more than about three to five years away, many people accept some investment risk (index funds, an ISA or a retirement account) for a higher expected return — enter that expected return in the rate box to model it. Shorter goals usually belong in cash, where the balance cannot fall. To see how a higher return compounds over time, try the compound interest calculator, or the investment calculator for a lump sum plus contributions.
How to reach your savings goal faster
The calculator shows the number; these habits help you hit it sooner:
- Automate it. Set up a standing order for the day after payday so the money moves before you can spend it. Consistency beats willpower.
- Chase a better rate. Moving from a 0.5% account to a 4–5% one can cover a meaningful slice of your goal for free — try both rates in the box above and watch the required deposit fall.
- Round up and sweep. Many banks round card purchases to the nearest unit and sweep the change into savings. It is small, but it is invisible and constant.
- Bank your windfalls. Tax refunds, bonuses, cash gifts and the money freed up when a subscription or loan ends are the fastest way to jump ahead — add them to your starting balance and re-calculate.
- Trim one recurring cost. Cutting a single £/$/€ 15-a-month subscription and redirecting it is a painless extra deposit every period.
- Give the goal a deadline and a name. “House deposit by 2029” is far more motivating than “savings”, and a date lets this tool work out the exact monthly figure.
Common savings goals and roughly what they cost
Not sure what target to enter? These are the goals people plan for most often. Amounts vary hugely by country and lifestyle — treat them as starting points and put your own number in.
- Emergency fund — three to six months of essential spending. The first goal most experts suggest, because it stops a surprise bill from becoming debt.
- Home deposit — often the biggest target, usually 5–20% of the property price. A longer timeline makes the monthly figure far more manageable.
- New (or newer) car — saving the cash instead of borrowing avoids interest entirely, so the whole price becomes your goal.
- Wedding — a fixed date is perfect for this tool: enter the total and the months left, and it returns exactly what to set aside.
- Dream holiday or big trip — a classic sinking fund; break the total into a comfortable weekly or monthly amount.
- A child’s future, or a career break — long horizons where compound interest does a large share of the work, as the breakdown chart shows.
Whatever the goal, the method is the same: pick the amount, pick the date, and let the calculator turn it into a simple, repeatable deposit.
The savings goal formula
No black box — here is the exact maths. To find the deposit you need, we grow your starting balance, subtract it from the goal, then solve the future-value-of-an-annuity formula for the payment.
Deposit needed each period
- PMT — the deposit you need each period
- Goal — your target amount
- S — your starting balance today
- i — effective rate per deposit period = (1 + annual rate ÷ c)c÷p − 1, for c compounds and p deposits a year
- N — number of deposits = deposits per year × years
Rearranged, the same equation solves for time (N = ln[(Goal + k) ÷ (S + k)] ÷ ln(1 + i), with k = PMT ÷ i) or for the final balance (FV = S(1 + i)N + PMT[(1 + i)N − 1] ÷ i). Start-of-period deposits multiply the deposit term by (1 + i).
Prefer a spreadsheet? The Excel & Google Sheets formula
You can reproduce this savings goal calculator in Excel or Google Sheets with two built-in functions. Assuming monthly deposits and monthly compounding:
Spreadsheet formulas
The monthly amount to save is the payment function:
How much you’ll have from a set deposit is the future-value function:
- rate — annual interest rate, e.g. 4.5
- starting_balance — what you have saved now
- goal — your target amount · deposit — the amount you pay in each month
The minus signs mark money leaving your pocket, which is how spreadsheets keep the cash-flow direction straight. For weekly or daily saving, swap the 12 for 52 or 365 and divide the rate to match. This calculator adds the extra step of converting between compounding and deposit frequencies for you.
How to use it & key terms
Enter your target amount and timeframe (or a monthly amount), your starting balance and expected return, then press Calculate for what you need to save.
| Term | What it means |
|---|---|
| Savings goal | The target amount you want to reach. |
| Monthly contribution | What you set aside each month toward the goal. |
| Time horizon | How long you have to reach the target. |
| Expected return | The growth rate on your savings (0 for a plain account). |
| Future value of an annuity | The maths that turns regular deposits into a final balance. |
| Starting balance | Any amount you already have toward the goal. |
Sources & methodology
The calculator uses standard time-value-of-money maths. Your starting balance is compounded to the goal date, and regular deposits are treated as an annuity. We convert your annual rate to an effective rate for the deposit period — (1 + rate ÷ c)c/p − 1 for c compounding periods and p deposits per year — so daily, monthly or annual compounding all give accurate results. The “how much to save” mode solves the future-value-of-an-annuity formula for the payment; “how long” solves it for the number of periods; “what I’ll have” evaluates the future value directly. Deposits default to the end of each period, with a start-of-period (annuity-due) option.

Why automatic savers win
The calculator gives you a monthly number, but hitting it month after month is where goals are actually won or lost — and the people who succeed rarely rely on willpower. They rely on automation. Setting up an automatic transfer that moves your savings amount out on payday, before you have a chance to spend it, quietly removes the monthly decision to save. The money is gone before it ever feels available, and what is left is simply what you spend. This is the old idea of paying yourself first, and it works because it turns saving from a repeated act of discipline into a default that happens on its own.
It helps to treat that transfer like a fixed bill rather than whatever is left over at the end of the month. Money that waits until month-end tends to evaporate; money moved first almost always stays put. If your budget is tight, a smaller automatic amount you never miss beats an ambitious figure you keep skipping, because consistency is what compounds. And when your income rises, nudging the transfer up by even a little lets your saving grow with your pay instead of your lifestyle quietly absorbing every raise.
Two supports make an automatic plan more durable. The first is a starting buffer — a small pot of easy-access cash for emergencies — so that an unexpected bill doesn't force you to raid the goal you are building. Without it, one bad month can undo a year of steady progress. The second is matching where you keep the money to how soon you need it: cash you plan to use in a year or two shouldn't be exposed to the swings of the market, where a downturn could arrive at exactly the wrong time, while longer-term goals can afford to chase growth because they have time to ride out the bumps.
Perhaps the most important habit is simply restarting. Life interrupts even the best plan — a job change, a big expense, a lean stretch — and a missed month or two is normal, not failure. What separates people who reach their goals from those who don't is not a flawless run but a willingness to resume the automatic transfer as soon as things settle. Set it, protect it with a buffer, raise it when you can, and start again whenever you slip. The maths above will take care of the rest.
Frequently asked questions
How much should I save each month to reach my goal?
Take the gap between your goal and what your starting balance grows to by the target date, then spread it across the number of deposits, adjusting for the interest each deposit earns — the sinking-fund formula. Enter your goal, timeline and rate and the calculator does it for you.
Can I use it in my own currency?
Yes. Choose US dollars, pounds, euros, Canadian and Australian dollars, rupees, yen and more. The symbol is only a label — the maths is identical everywhere.
How does interest change how much I need to save?
A higher rate means both your starting balance and every deposit grow faster, so you set aside less to reach the same target. At a 0% rate the tool simply divides the remaining amount by the number of deposits.
What if I already have some savings?
Enter it as your starting balance. It is grown forward to the goal date with compound interest and subtracted first, so you only fund the remaining gap.
Does the compounding frequency matter?
A little — daily compounding earns slightly more than monthly for the same rate, nudging the required deposit down. The tool converts your rate to an effective rate for the deposit period so the answer is accurate whichever you pick.
Can it tell me how long it will take?
Yes. Switch to “How long it takes”, enter the amount you can deposit each period, and it solves for the years and months needed.
Should deposits be at the start or end of the period?
End of period is the standard assumption. Start-of-period deposits earn one extra period of interest, lowering the amount needed slightly; you can switch between the two.
Can I set a savings goal by a date?
Yes. Enter the years and months between now and your target date and it returns the exact amount to save each period. Or switch to “How long it takes” to find the date from a set deposit.
How much should I save by 30, 40 or 50?
There is no single number — use the years until that birthday as your timeline and enter your target. A rough guide is about 1× your salary saved by 30, 3× by 40 and 6× by 50, but these are loose benchmarks, not fixed goals.
Does it account for inflation?
Not with a separate box, but you can allow for it by entering a real return: subtract expected inflation from your rate (say 5% growth minus 3% inflation ≈ 2%) to see the goal in today’s money.
Can I use it with no interest?
Yes — set the rate to 0 and it simply divides the remaining amount by the number of deposits, which suits a plain cash savings plan.
Can I build this in Excel or Google Sheets?
Yes. The monthly amount is =PMT(rate/100/12, years*12, -starting_balance, goal) and the future balance is =FV(rate/100/12, years*12, -deposit, -starting_balance). The spreadsheet section above has the details.
Can I set a goal based on my income?
Yes, indirectly. A common rule is to save about 20% of take-home pay (the 50/30/20 budget) — work out that amount and enter it as your deposit, or set a target and the tool shows the share of your pay it needs.
How much should I save each month for a house deposit?
Decide your target deposit (often 5–20% of the price) and your timeline, then enter both here. For example, saving a £20,000 deposit in 3 years is roughly £550 a month — a little less if it earns interest. Add any savings you already have as your starting balance and the tool shows the exact monthly amount.
