How much rent can I afford? Three rules, one answer
This rent affordability calculator answers “how much rent can I afford?” from your pay. Enter a salary, a monthly wage or an hourly rate, and it applies the three tests people actually meet: the 30% rule used by housing researchers, the landlord income test (40 times the monthly rent in much of the US, 30 times in the UK) and the 50/30/20 budget on your take-home pay. The answer is the highest rent that passes all of them, and the table shows which rule bites first.
It works for renters in the United States, the United Kingdom, India, the UAE and Australia: pick a country and the currency, the usual landlord multiple and a realistic example load in. Type the rent of a flat you like and every rule says whether it passes, and what income it would need. Everything runs in your browser; the result is a planning estimate, not financial advice.
How to use the Rent Affordability Calculator
- Choose your Country and whether your pay is Yearly, Monthly, Weekly or Hourly.
- Enter your Gross pay, before tax (and Hours a week for hourly pay).
- Add Take-home pay a month and Other essentials for the 50/30/20 check, and any Bills not in the rent.
- Adjust the Landlord rule multiple if your landlord or agent uses a different one (0 turns it off).
- Type the Rent you are looking at to see, rule by rule, whether it passes and what income it needs.
Rent Affordability Calculator features
Hourly, weekly, monthly or yearly pay
Hourly pay is turned into a yearly figure with your own hours (rate × hours × 52), so “making $25 an hour” works directly.
Three rules side by side
The 30% benchmark, the landlord income multiple and the 50/30/20 budget, with the tightest one picked as the answer.
Country-aware defaults
US 40× and UK 30× landlord tests, ₹ with lakh grouping for India, AED and A$ — each with notes on local costs such as council tax or rent cheques.
Bills handled honestly
The 30% benchmark includes utilities, so bills you pay on top of rent come off the 30% figure and out of the 50/30/20 needs.
Rent check and income needed
For any rent, see the pass or shortfall for each rule and the income each would require.
How the rent affordability rules work
- 30% rule: rent plus utilities should take no more than 30% of gross monthly income. It comes from US housing policy — HUD counts a household as cost-burdened above 30% and severely cost-burdened above 50% — and is widely used elsewhere. Max rent = gross pay a month × 30% − bills.
- Landlord income test: many US landlords want a yearly income of at least 40 times the monthly rent; UK referencing companies commonly ask for 30 times (the same as 2.5 times the annual rent). Max rent = yearly gross pay ÷ multiple. It is screening practice, not law, and guarantors are usually asked for more.
- 50/30/20 budget: half of take-home pay for needs, 30% for wants and 20% for savings. Rent, bills and other essentials together should fit in the 50%, so max rent = take-home × 50% − essentials − bills.
Worked example: how much rent can I afford making $25 an hour?
At $25 an hour for 40 hours a week, gross pay is $25 × 40 × 52 = $52,000 a year, or $4,333 a month. The 30% rule allows $1,300 a month, and the 40× landlord test gives the same: $52,000 ÷ 40 = $1,300. With $3,600 a month take-home and $700 of other essentials, the 50/30/20 budget leaves $1,800 − $700 = $1,100, so that is the rent this calculator recommends.
A $1,200 flat would pass the landlord’s check but break the budget by $100 a month. To qualify for $1,200 under the 30% rule you would need $48,000 a year, and to fit it into 50/30/20 you would need $3,800 a month after tax.
| Pay | Yearly income | 30% rule | 40× rule |
|---|---|---|---|
| $20 an hour (40 h) | $41,600 | $1,040 | $1,040 |
| $25 an hour (40 h) | $52,000 | $1,300 | $1,300 |
| $30 an hour (40 h) | $62,400 | $1,560 | $1,560 |
| £35,000 a year (UK, 30×) | £35,000 | £875 | £1,167 |
Which rule should you trust?
The rules answer different questions. The landlord test decides whether you get the flat; the 30% rule is a broad measure of strain; 50/30/20 checks whether your own budget still works. In expensive cities the landlord test often allows more than is comfortable, while for high earners 30% of gross can be more than they need to spend. Using the tightest of the three is a cautious default — raise or lower the housing share if your circumstances differ.
Remember the one-off costs too: deposit, the first month’s rent, agent or broker fees and moving costs. Saving towards a home of your own instead? The rent vs buy calculator compares the two, and the down payment calculator shows how long a deposit takes to save. For take-home pay from a salary, try the salary calculator.
Rent Affordability Calculator FAQ
How much rent can I afford on my salary?
Multiply your gross monthly pay by 30% and subtract any bills you pay on top of rent. This rent affordability calculator also checks the landlord income test and the 50/30/20 budget and gives the lowest of the three as a safe figure.
How much rent can I afford making $25 an hour?
About $1,300 a month before bills: $25 × 40 hours × 52 weeks is $52,000 a year, and both the 30% rule and the 40× landlord rule give $1,300. If your take-home budget is tight, the 50/30/20 check may suggest less.
What is the 40x rent rule?
Many US landlords require a yearly gross income of at least 40 times the monthly rent — $80,000 for a $2,000 flat. It is a screening rule, not a law, and co-signers or guarantors usually have to show more.
How do UK landlords work out rent affordability?
Most letting agents and referencing companies ask for a yearly income of at least 30 times the monthly rent, which equals 2.5 times the annual rent. Guarantors are often asked for 36 times. Choose United Kingdom to apply the 30× test.
Does the 30% rule use gross or net income?
Gross income before tax, and the 30% is meant to cover utilities as well as rent. If you only know your take-home pay, use the 50/30/20 check, which is based on net income.
Is spending more than 30% on rent bad?
Not always, but it leaves less room for savings; above 50% is a severe burden.
