How much rent can I afford?

Enter your salary to get a quick estimate before you start viewing properties.

Use income before tax, not take-home pay.
Affordable monthly rent:
£1,000

Based on your £30,000 annual income, the maximum rent you can afford is £1,000 monthly.

If you want to compare that rent budget with the longer-term cost of owning, use the Rent vs Buy Calculator.

See below for how this is calculated.

How is rental affordability calculated?

The general rule of thumb is that your gross annual income should be 30 times the monthly rent.

Gross income means what you earn before tax and other deductions. You can also work it the other way round by multiplying the yearly rent by 2.5.

For example

If the monthly rent was £500, then you would need an gross annual income of £15,000 to pass the affordability check.

Frequently Asked Questions

Should I enter gross or net income?

Enter your gross annual income, not your take-home pay. Most landlords and referencing checks use income before tax, so entering net pay will make the result look too low.

Gross income is what you earn before tax, National Insurance, pension deductions, and anything else is taken off.

Net income is what lands in your bank account after those deductions.

What does this calculator leave out?
It gives you a quick estimate from your gross income. It does not include council tax, travel costs, childcare, existing debt payments, or the rest of your monthly budget, so treat the result as a starting point rather than a safe spending target.
Why might a landlord or agent be stricter than this result?
The 30x rule is only the first screen. Referencing checks may also look at debt, dependants, missed payments, probation periods, or whether your income changes month to month, so the final limit can come out lower than the headline estimate.
Can I use joint income for rent affordability?
Usually, yes, if everyone on the tenancy is named and their income is accepted by the landlord or referencing company. To estimate that, add the incomes together and enter the combined figure in annual income.
How does this compare with a full renting budget?
This tool tells you what a landlord-style affordability check might allow. For the wider monthly cost of living in a property, including rent over time, use the Renting Calculator. If you are deciding between renting and owning, compare both with the Rent vs Buy Calculator.
