Budgeting: How much rent can I afford? A rule, a table and the budget check

How much rent can I afford?

About 25% to 30% of your take-home pay, as long as rent, bills, groceries and minimum debt payments together stay under half of it.

The answer you'll hear most is the 30% rule: rent should be no more than 30% of your gross income, before tax. It's a long-standing rule of thumb, and a decent starting point. But you pay rent from what reaches your account, not from your salary, so the safer test starts from take-home pay. That's the number on your payslip after tax, pension and other deductions, or the amount that lands in your bank account each month.

What's wrong with the 30% rule?

Nothing, except that it's based on gross income, and tax comes out first.

Here's a worked example in round numbers, the same in any currency. On a salary of 60,000, gross monthly income is 5,000, and 30% of that is 1,500. Say take-home pay is 4,000 after tax and deductions. Then 1,500 in rent is 37.5% of what you actually have to spend. That's a lot more than 30%, and the gap grows the more tax you pay.

The 30% rule also ignores everything else. Two people on the same salary, one with a car loan and one without, can't afford the same rent.

How much rent is that on your take-home pay?

25% leaves room for savings and for the months that go wrong. 30% works if your other fixed costs are low. Above 30% of take-home, something else has to give.

How do you check a rent against your whole budget?

Use the needs half of the 50/30/20 rule: rent, utilities, groceries, transport to work, insurance and minimum debt payments should fit in 50% of take-home pay.

Continuing the example, on 4,000 take-home, needs get 2,000.

At 1,100, it fits exactly. At 1,400, the same list comes to 2,300, and either savings or spending money has to shrink by 300 a month. That's the real cost of the nicer flat, and it's worth knowing before you sign. The budget calculator does this split for your own pay.

What do renters actually spend?

For people living alone in the US, housing is by far the biggest cost. In the Bureau of Labor Statistics' Consumer Expenditure Survey for 2025, one-person households spent an average of $14,172 a year on shelter, about $1,181 a month. Half of them rented; the figure includes owners' housing costs too.

Rents are still rising. The rent index rose 2.8% in the 12 months to September 2026, according to the BLS Consumer Price Index. On a 1,200 rent, a similar rise at renewal would be about 34 a month. Leave room for it.

What else does a new flat cost?

The deposit, the first month's rent, moving, and anything you need to buy. Together these can come to two months' rent or more.

Save for them separately, so the move doesn't empty your emergency fund. Check the bills that come with the flat too: some rents include heating or water, some don't, and a cheaper flat with expensive bills can cost more overall. If you're sharing, how to split rent with roommates covers fair splits when rooms aren't equal.

Is it ever fine to pay more?

Sometimes. In an expensive city, close to work, rent above 30% of take-home can make sense if it cuts transport costs or time. But the rest of the budget has to work around it, and savings are usually what gives.

If you do stretch, plan the next step: a pay rise, a flatmate, or a cheaper move at renewal. Paying 40% for one year is a decision; paying it indefinitely is a squeeze.

How do you keep rent from crowding out everything else?

Set the rent as a fixed line in a monthly budget and give every other category its own amount.

In Wealtie, set your monthly budget to take-home pay minus rent and savings, split it by category, and Budget Health warns you mid-month if your spending pace will take you over. Rent can be a recurring transaction that logs itself on the due date, so it never surprises the budget.
