Is that flat affordable, or does it only look affordable until the car payment and the loan come out? The Rent Affordability Calculator works from what actually lands in your account and what already leaves it, then tells you the rent that fits around both.
Short answer: The Rent Affordability Calculator is a free EizTools tool that works out how much rent you can comfortably afford. Enter your income and commitments, pick a rule, and it returns a maximum rent with a budget.
What is Rent Affordability Calculator?
It converts income into a rent ceiling. Describe your take home pay and your existing commitments, and the Rent Affordability Calculator returns the rent you can carry, usually alongside a snapshot of what is left afterwards.
The 30 Percent Rule, And When It Breaks
Thirty percent of income on rent is the rule everyone quotes. It comes from a time of smaller debts and cheaper transport, and it says nothing about what else you are paying. Someone with a car loan and student debt at 30% is stretched. Someone with neither has room. That is why the Affordability Rule dropdown offers alternatives.
Five rules
30% of gross, 30% of net, the 50/30/20 budget, a rent to income ratio, or a conservative 25%.
Three rent tiers
A budget view that returns comfortable, stretch and maximum figures instead of one number.
Shared housing
Audience covers single renters, roommates, couples and first time renters, which changes the maths.
Affordability Rule And Budget View
| Rule | Suits |
|---|---|
| 30% of net income | Most renters, since it uses money you actually receive |
| Conservative 25% | Irregular income, or saving hard for something else |
| 50/30/20 budget | Anyone who wants the whole budget, not just the rent line |
| Rent to income ratio | Meeting a landlord requirement, which is often stated this way |
Use net income wherever the rule allows it. Gross figures produce a ceiling that ignores tax and looks reachable right up to the point the rent is due.
How Does Rent Affordability Calculator Work?
- Type your position: "take home 4,500 a month, 350 car payment, 300 in other debts, looking to rent alone."
- Choose an AI model before you generate.
- Set your currency, Affordability Rule to 30% of net income, Budget View to Three rent tiers, Audience to Single renter.
- Leave Output Detail on Normal and generate.
- Read the comfortable tier first, not the maximum one.
- Run it again as Roommates or shared to see how splitting changes the range.
Rent is not the whole cost Add utilities, internet, council tax or local equivalent, contents insurance and any parking. A flat at the top of your range with bills on top is a different flat from the one the number described.
Tips Before You Sign
- Aim at the comfortable tier, so a rent rise next year does not force a move
- Check what the deposit and first month cost together, which is the real barrier
- Ask which bills are included, since the same rent can mean very different totals
- Leave room for saving, because rent that consumes everything traps you where you are
Nothing on EizTools costs anything or needs an account, and each tool arrives with controls made for its own job plus a model choice on the page. Housing decisions sit next to savings and budget questions, and the tool library covers the planners for both.
Frequently Asked Questions
Should I use gross or net income?
Net, wherever possible. Landlords often assess on gross, but your ability to pay depends on what arrives after tax. Running both shows the gap between what you qualify for and what you can carry.
Does the Rent Affordability Calculator include bills?
Only if you list them. Add utilities, internet and local taxes to your prompt so the leftover figure is realistic rather than an optimistic number that ignores the monthly extras.
How does sharing change the calculation?
Set Audience to Roommates or shared and give the split. Sharing usually lifts the affordable rent considerably, though it also brings joint liability on most tenancy agreements.
What if my income varies?
Use your lowest typical month rather than an average, and choose the conservative 25% rule. Renting against a good month is how irregular earners end up in arrears in a quiet one.
Rent is the payment that shapes every other one for the length of the lease. Work from net income, count the bills, and choose the comfortable figure rather than the one a letting agent says you qualify for.
