Quick answer
A savings goal calculator works in two directions. Give it the goal, what you have already saved and a monthly contribution, and it divides the remaining amount by the contribution to return the months to the goal and the month you reach it. Give it a target date instead, and it divides the remaining amount by the months until that date to return the monthly contribution you need. It assumes no interest, which keeps it honest for short goals and slightly pessimistic for long ones. A small table shows how redirecting a $3, $5 or $8 daily habit moves the date.
This calculator runs entirely in your browser: nothing you type is uploaded, stored or sent anywhere, and it keeps working with the connection off. It answers the two questions every savings goal comes down to. If you know what you can put aside each month, it tells you when you get there. If you know when you need the money, it tells you what to put aside each month. Under the result, a small table shows what redirecting a daily habit of a few dollars does to either answer, because that is usually where the missing contribution is hiding.
How to use it
- The goal is the total you want to have on the day you need it. For an emergency fund, one month of essential expenses is a common first target, and the guides linked below help pick the figure. For a purchase, use the real price including the parts everyone forgets: delivery, insurance, a first month's rent on top of the deposit.
- Then what you already have set aside for this goal. The calculator works on the difference between the two, so a head start shortens everything below it. If the answer is nothing, type zero.
- The mode selector asks what you already know. Monthly contribution, when you have a figure you can save each month and want the date. Target date, when the date is fixed by a trip, a lease or a tuition deadline and you need the monthly amount. The field beneath changes to match.
- In monthly mode the big figure is a number of months, with the arrival month under it. In date mode the big figure is the contribution per month, with the month count under it. Either way, the amount still to save is shown too.
- Last, the habit table. Three rows for a $3, $5 and $8 daily habit, each showing what it costs per month and per year, and what redirecting it does: months sooner in one mode, a smaller required contribution in the other. The amounts are examples. The arithmetic works for any daily figure.
What the result means here
The calculator does two divisions and a calendar lookup.
In monthly mode, the remaining amount (goal minus saved) is divided by the monthly contribution, and the result is rounded up to whole months, because you cannot arrive in the middle of a transfer. Those months are added to today's date to give the arrival month. If you have $4,500 to save at $250 a month, that is 18 months, and the calculator names the month 18 months from now.
In date mode, the calculator counts the full months between today and the target date, ignoring partial months so that it never assumes a transfer you have not had time to make, and divides the remaining amount by that count. If $4,500 must be ready in 12 full months, the contribution is $375 a month.
The habit table multiplies each daily amount by 30 for the month and 365 for the year, then reruns the main calculation with that money added to the contribution or subtracted from the required amount. A $5 daily habit is $150 a month. Added to the $250 above, the 18 months become 12; subtracted from the $375, the required contribution becomes $225.
No interest is applied, in either direction, and that is deliberate. Over a year or two, savings interest moves the answer by weeks, while a rate field would suggest a precision the plan does not have. Leaving it out makes the calculator slightly pessimistic, which is the safe side to be wrong on. Any interest you earn just lands you early.
Rounding up is deliberate too, and it is the other thing people query. Eleven and a quarter months becomes twelve, not eleven, because you cannot arrive in the middle of a transfer. A tool that reported 11.25 would be more precise and less true.
Five ways a plan like this goes wrong
The arithmetic is exact. The assumptions behind it are where plans come apart.
An aspirational contribution is the commonest failure by a distance. Someone types the monthly figure a good month can afford, the calculator reports a date, and the date is never reached, so the goal quietly turns into a source of guilt. Type the figure that survives a bad month instead, even when it is smaller, and let the tool show the honest cost as extra months. A contribution kept for 18 months beats a larger one abandoned in month four, every time. The guide on how long saving takes works through choosing it.
Distance is the second. Past three or four years, the two things this page ignores start to bite: interest, which helps you, and inflation, which does not. A goal set today for a purchase in 2031 will cost more than the figure you type. Treat the result as a floor over that horizon, revisit the goal amount once a year, and ask a qualified adviser about where the money should sit.
Some goals have neither a date nor a contribution, which means they are wishes. Nothing wrong with that, but the calculator needs one of the two before it can say anything. If you can name neither, start smaller: the daily spending allowance calculator tells you what is spendable this month, and whatever you do not spend is where a contribution figure comes from.
Then there is the account problem. The whole plan assumes money saved stays saved, and a goal balance that lives in the same account as everyday spending gets borrowed from. The schedule drifts from reality without anybody deciding to abandon it. Both the CFPB and MoneyHelper put separation ahead of any product choice. Where the money should sit is a personal question. That it should sit somewhere else entirely is not.
The last one is about order. Saving for a trip while there is no cushion at all means the trip fund is the emergency fund, whatever it is called. CFPB guidance suggests a small, reachable target before anything else, so if the goal on this page would be the first savings you have ever had, make the cushion the first goal and the trip the second. How to save $1,000 in three months is written for exactly that starting point.
Four goals, run through
Start in monthly mode, wanting a date. Goal $5,000, already saved $500, contribution $250 a month. Remaining $4,500 divided by $250 is 18 months, so if today is September 2026 the calculator names March 2028. The habit table then shows that redirecting $5 a day adds $150 a month, and $4,500 divided by $400 is 11.25, rounded up to 12. Six months sooner. September 2027 instead of March 2028.
Now reverse it. Goal $3,600 for a deposit due in 9 full months, nothing saved yet. Remaining $3,600 divided by 9 is $400 a month. Cutting an $8 daily habit is $240 a month, which brings the required contribution down to $160. A $3 habit is $90 a month, bringing it to $310.
A first emergency fund looks like this. Goal $1,000, saved $120, contribution $110 a month. Remaining $880 divided by $110 is exactly 8 months. Add the $3 habit and the contribution becomes $200, which gets there in 5 months.
The fourth is the one people never type in. Goal $2,000, saved $2,100: the calculator says the goal is reached and clears the table. Worth doing anyway, because it is surprisingly common to keep feeding a goal that finished months ago while a newer one sits at zero.
Making the transfer happen
The calculator gives you a monthly contribution and a date. Between now and that date, two things have to keep happening: the transfer has to be made, and the money has to stay where it was put.
Cash Book's Accounts are built for the second part. A savings account with its own balance sits next to cash and cards, a transfer into it is logged like any transaction, and the Accounts screen shows one net-worth number over all of them. The balance of that one account, climbing by the contribution each month, is the progress bar for the goal on this page. The app has no named goal feature; it has a number that goes up when you keep the promise, which is the same thing with fewer settings.
The habit table is where Budgets come in. If the $5 a day you are redirecting is coffee, a per-tag budget on the coffee tag with a cap of $60 a month makes the redirect visible: a thin progress bar that fills at the pace you chose, and turns red only if you cross it. A monthly allowance under the Home number does the same for everything variable at once.
Both of those depend on logging that actually happens, which is why the voice logger matters more here than it first seems. A goal fails in the small purchases nobody records. When "coffee four twenty" takes three seconds to log, the coffee tag stays true and the habit table stops being hypothetical.
For the wider routine, how to make a monthly budget that sticks covers where the contribution comes from each month, and how to stop impulse buying is about the purchases that most often replace it.
The other tools
The 50/30/20 budget calculator gives a starting figure for the monthly contribution as 20 percent of take-home pay. The daily spending allowance calculator shows what is spendable this month once that contribution is set aside. The small purchases calculator is the habit table on this page extended to any amount and any frequency. The subscription cost calculator finds the recurring lines that could become contributions, and the hours of work calculator reprices the goal itself in hours of your time.
Where to go next
Type a contribution you would keep in a bad month and read the date without flinching. If it is further away than you hoped, the habit table is the first lever, the subscription calculator is the second, and the guide on how long saving takes goes through the rest in order. If the goal is a first cushion, the $1,000 in three months guide is a plan at the scale where most people start. Then open a savings account in Accounts, make the first transfer, and let the balance do the counting.
A savings goal is one number and one date. The calculator makes both explicit; the transfer each month is what makes them true.

Frequently asked questions
How does the savings goal calculator work?
It subtracts what you have saved from the goal to get the remaining amount. In monthly mode it divides that by your contribution and rounds up to whole months, then adds those months to today for the date. In date mode it counts the full months to your date and divides the remaining amount by that count. There is no interest, no fees and no inflation in the arithmetic.
Why does the calculator ignore interest?
Because for most goals under two years the interest on a savings account changes the answer by a few weeks at most, and adding a rate field invites a precision the plan does not have. Leaving interest out makes the result slightly pessimistic, which is the safer direction. For a long goal, treat any interest earned as a bonus that lands early.
What if my target date is less than a month away?
The calculator asks for a date at least one full month out, because it works in months. For a goal a few weeks away, divide the remaining amount by the weeks yourself, or use the daily spending allowance calculator, which works in days. Very short goals are really a question of this month's spending, not of a savings plan.
How is the habit table calculated?
Each row multiplies a daily amount by 30 for the month and by 365 for the year. In monthly mode it then adds the monthly figure to your contribution and recalculates the months, showing how many sooner you arrive. In date mode it subtracts the monthly figure from the required contribution. The three amounts are examples; the arithmetic is the same for any daily habit.
Should I save for one goal at a time or several?
That depends on the goals and on you. A single goal is easier to track and finishes sooner; several goals in parallel keep each one visible. What matters more is that the money for each goal has a named place, such as a separate account, so it is not mistaken for spending money. For questions about which goals to prioritise, a qualified adviser is the right person to ask.
What is a realistic monthly contribution?
Whatever survives a bad month. A contribution you can make in every month, including the one with the car repair, is worth more than a larger one you abandon in month three. Many people start from the savings share of a 50/30/20 split and adjust it down to the figure that feels almost too easy. The calculator shows the cost of that choice as months, which is the honest trade.
Where should I keep the money while I save?
Somewhere separate from everyday spending, so that the goal balance and the spending balance are never the same number. Public guidance from the CFPB and MoneyHelper both stress separation over any particular product. Which account type suits you depends on the goal, the timeframe and your circumstances, and is a question for a qualified adviser rather than a calculator.
How do I keep going once the plan is set?
Automate the transfer on payday so the contribution happens before you can spend it, and check the balance against the calculator's schedule once a month. Watching the number climb toward the goal is the part that sustains the habit. If a month is missed, recalculate rather than doubling up; a plan that absorbs one bad month lasts longer.
Can Cash Book track a savings goal?
Cash Book does not have a named goal feature. What it has is Accounts: a savings account with its own balance, transfers into it logged like any transaction, and one net-worth number over all accounts. Set the goal and the monthly amount here, transfer that amount each month, and the account balance on the Accounts screen is your progress bar.
