How much should I save each month?

Aim for 20% of take-home pay, which is £480 a month on a £2,400 pay packet. If that number made you wince, keep reading: the order you save in matters more than hitting the percentage, and any amount paid first beats a bigger amount paid last.

The 20% rule, properly applied

The 20% figure comes from the 50/30/20 budget: 50% of take-home pay for needs, 30% for wants, 20% for savings and extra debt repayment. On £2,400 a month that is £1,200 for essentials, £720 for lifestyle and £480 for your future self. On £1,800 it is £900, £540 and £360.

Two details people get wrong. First, it is 20% of take-home, not gross salary. If you are not sure what your take-home actually is, the take-home pay calculator gives you the real monthly figure after tax, National Insurance, pension and student loan. Second, the savings bucket includes extra debt repayments above the minimum. Throwing £200 at a credit card charging 24% counts; you are buying back guaranteed interest, which no savings account can match.

The percentages are a starting grid, not a law. In an expensive city your needs might genuinely run to 60%, which squeezes the other buckets. The budget planner lets you adjust the ratios and compare the targets against what you actually spend.

The order matters more than the amount

Where the money goes is decided before how much. Work down this list:

1. A starter emergency fund of about £1,000. This stops the next surprise bill becoming new debt. Our emergency fund guide covers the full three-to-six-months target, but £1,000 does most of the early work.
2. Your full employer pension match. If your employer matches contributions up to, say, 5%, every £1 you put in is doubled before any investment growth. It is the highest guaranteed return available to most people, and skipping it is leaving pay on the table. Check what yours is worth with the pension contribution checker.
3. Expensive debt. Anything charging more than roughly 8%: credit cards, overdrafts, high-rate personal loans.
4. The full emergency fund, then named goals: house deposit, car, wedding, investing for the long term.

Notice that the first two steps usually cost less than 20% combined. The rule is the ceiling for an ordinary month; the order is what stops the money being wasted.

Pay yourself first

Saving whatever is left at the end of the month reliably produces nothing, because spending expands to fill the account. Reverse it: set a standing order from your current account to a savings account for the day after payday. The £480, or £200, or £50, leaves before you can spend it, and you budget with what remains.

This also turns vague intentions into a number you can plan around. A £6,000 car fund in two years needs £250 a month with no interest, or about £240 a month in an easy-access account paying 4%. The savings goal planner does this both ways: tell it a monthly amount and it gives you the date, or tell it the date and it gives you the monthly amount.

When 20% is impossible

For plenty of people, especially early in a career or mid rent crisis, 20% is fantasy and pretending otherwise just produces guilt. Three honest moves:

• Start at any non-zero number. £50 a month is £600 a year plus the habit, and the habit is the asset. Standing orders scale up in thirty seconds when pay rises.
• Capture pay rises before lifestyle does. If your take-home goes up £120 a month, redirect at least half of it to the standing order on day one. You never feel the loss of money you never spent.
• Attack the needs bucket once a year. Remortgage or switch energy, insurance and phone contracts. A £60 monthly cut to essentials is a £60 pay rise for your savings rate, with no extra tax.

The wrong response is to save nothing until you can save properly. Twenty percent is where you are heading, not the entry fee.

Common questions

Is the 20% based on gross salary or take-home pay?

Take-home pay, after tax, National Insurance, pension and student loan deductions. Someone on £35,000 gross might take home around £2,300 a month, so the target is roughly £460, not £583.

Do my workplace pension contributions count towards the 20%?

The 50/30/20 split works on take-home pay, so contributions taken from your payslip sit outside it. They absolutely count towards your overall saving, though, which is why hitting the full employer match comes before most other goals.

Should I save or overpay my mortgage?

Build the emergency fund and take the pension match first. After that, compare your mortgage rate with what easy-access savings pay: if savings pay more after tax, save; if the mortgage rate is higher, overpaying gives a guaranteed return at that rate.

Is saving £50 a month actually worth it?

Yes. It is £600 a year, which covers a typical car repair or vet bill without debt, and the standing-order habit is what later absorbs pay rises. Small and automatic beats large and theoretical.

Where should my monthly savings actually go?

Emergency fund money goes in easy-access savings at a competitive rate. Goals within about five years stay in cash too (easy access or a cash ISA). Only money you will not touch for five-plus years should go into investments.
