Rent affordability check

Use your per-person share of rent if you live with others.

What this means

This tool calculates your rent-to-income ratio and compares it against location-adjusted affordability thresholds to give a green, amber, or red verdict.

Formula used

Rent affordability ratio = (per-person monthly rent ÷ monthly take-home pay) × 100. Thresholds: London 35% / 50%, major cities 30% / 45%, elsewhere 30% / 40%.

Worked example

Take-home £2,200/month. Rent £750/month. Ratio: 34%. In a major city that's amber — above the 30% guideline but below the stress threshold. In London it would be green.

Common questions

What is the 30% rule?
The standard guideline is that rent should not exceed 30% of gross income. On take-home pay the effective threshold is slightly higher. This tool uses take-home pay and adjusts thresholds by location, since rents in London and major cities run significantly higher.

Should I include bills in my rent figure?
If your rent includes bills, your actual outgoing on housing is the rent figure. If bills are on top, your true housing cost is rent plus bills. The tool flags which you've entered so you can interpret the result accordingly.

Plain-English summary

Enter your figures to see what share of your take-home pay goes on rent and whether that's affordable for where you live.

This section translates the result into a short, direct takeaway rather than leaving the page at a bare number.
