How to Save for a Goal (the Simple Monthly-Target Method)
Most savings advice tells you to "save more" and stops there. That is the part everyone already knows. The bit that actually works is turning a big, vague goal into a small, specific number you put aside every time you are paid. Do that, and saving stops being a test of willpower and becomes a habit you barely notice.
Here is the simple method, the maths behind it, and how to keep several goals on track at once without losing the thread.
Start with a target and a deadline
A savings goal needs two numbers: how much and by when. "Save for a holiday" is a wish. "£1,800 by next July" is a goal you can plan around.
Pick your target honestly. If it is a holiday, add up the flights, the accommodation and a bit of spending money. If it is a house deposit, work back from the kind of place you want. If it is an emergency fund, base it on your monthly essentials (our emergency fund guide walks through that one). The deadline can be a real date or just a rough month, the point is to give the goal an end.
The monthly-target method
Once you have a target and a deadline, the monthly amount works itself out:
Monthly amount = (target − what you have already) ÷ months until the deadline
A worked example:
- Target: £1,800 for a holiday
- Already saved: £300
- Months left: 10
(£1,800 − £300) ÷ 10 = £150 a month.
That is the whole trick. A scary "£1,800" becomes a manageable "£150 a payday", and you immediately know whether the deadline is realistic. If £150 a month is comfortable, you are done planning. If it is a stretch, you have three honest levers: extend the deadline, lower the target, or find a bit more to save. Far better to discover that now than three months before the trip.
Save the same amount every payday
The method only works if the money actually moves. The most reliable way is to make it automatic and to do it the moment you are paid, before the money has a chance to drift into everyday spending. This is the same idea as budgeting by payday: give every pound a job as soon as it lands.
A few things that make it stick:
- Pay your goal first. Treat the transfer like a bill, not the leftovers at the end of the month. Leftovers rarely show up.
- Keep goal money separate. A different account, or at least a clearly labelled pot, stops you spending it by accident.
- Match the rhythm to your pay. Paid weekly or fortnightly? Divide the monthly amount down and move a smaller sum more often. It is the same total, and it hurts less.
Saving for more than one thing at once
Real life is rarely a single goal. You might be saving for a holiday, a new car and an emergency fund all at the same time, and that is where people lose track, because the numbers tangle together in one account.
The fix is to give each goal its own target, deadline and monthly amount, then add them up. If the holiday needs £150, the car fund £100 and the emergency fund £75, you are putting aside £325 a month across three goals, and you can see exactly how much of your savings belongs to each.
When the total is more than you can manage, you prioritise rather than abandon. An emergency fund and any time-sensitive goal usually come first; the nice-to-haves can take a longer deadline and a smaller monthly amount. Nothing gets dropped, it just gets a realistic pace.
A quick word on goals versus sinking funds
If you have read our sinking funds guide, this will feel familiar, and the two do overlap. The simple distinction: a savings goal is something you are building towards and will eventually spend in one go, like a holiday or a deposit. A sinking fund smooths an expected-but-irregular bill you will face again and again, like Christmas or the car service. Same habit, slightly different jobs, and a complete budget has room for both.
Do it automatically
You can run the monthly-target method on the back of an envelope, and for one goal that is fine. The moment you have several, doing the maths by hand every time a target, a balance or a deadline changes gets old fast.
That is exactly what our Savings Tracker is built to do. Set a target and a deadline for each goal and it works out the monthly amount for you, then shows your progress, how many months are left and the date you are on track to hit each goal, all in one automated Google Sheet. Log what you put in, watch every goal fill up, and see a single Health Score telling you how your saving is going overall. There is an optional AI money coach you can switch on with your own free key for a bit of plain-English encouragement, and it only ever sees figures and first names, never the full picture and never sent to us. It lives in your own Google account, never connects to your bank, and is a one-time purchase with no subscription.
Set the goal once, and the tracker keeps the maths honest for you.

Frequently asked questions
How do I work out how much to save each month for a goal?+
Take your target, subtract what you have already saved, and divide by the number of months until your deadline. That is your monthly amount. If it feels too high, extend the deadline, lower the target, or find a little more to put aside.
How can I save for several goals at the same time?+
Give each goal its own target, deadline and monthly amount, then add them together for your total monthly saving. Keeping them separate means you always know how much of your savings belongs to each goal, and you can prioritise the urgent ones if money is tight.
What is the difference between a savings goal and a sinking fund?+
A savings goal is something you build towards and spend in one go, like a holiday or a house deposit. A sinking fund smooths an expected, repeating-but-irregular cost like Christmas or the MOT. The habit is the same; a full budget usually has both.
Where should I keep money I am saving for a goal?+
In a separate, clearly labelled savings pot or account, so it is not spent by accident but is easy to reach when you need it. Keeping goal money out of your current account is one of the simplest ways to actually hit the target.
Do I need an app that links to my bank to track savings goals?+
No. You can track every goal in a simple spreadsheet that lives in your own Google account, with no bank connection and no subscription. See our guide to budgeting without linking your bank account.
