How the affordability status works
The first version keeps the logic simple so the result is fast and easy to understand:
- Comfortable if rent is 30% or less of take-home income and you still have money left after expenses.
- Tight if rent sits around 30% to 40% of take-home pay or your remaining money after savings is quite low.
- Risky if rent is above 40% of take-home pay, total essential spend is very heavy, or your remaining money drops below zero.
What this means in real life
In many UK cases, the tension is not just the rent itself. It is the combination of rent, council tax, bills, food and transport that turns a salary from “looks fine on paper” into “feels tight each month”.
- Housing usually absorbs the largest share of income.
- Council tax and utilities often add another £250 to £400.
- Transport, groceries and family obligations can narrow the margin very quickly.

Why your real result may differ
- The 30% to 35% rent rule is only a rough guide and does not fit every household.
- Commuting, debt payments, irregular income and the exact council tax set by your local authority can change the picture quickly.
- Landlords and letting agents may use their own affordability formulas or require a guarantor.
- Your savings goal can make a rent level feel tighter even if the bare essentials are covered.
Common patterns we see
- Many users underestimate council tax and utility costs when they first test an affordable rent level.
- Rent usually consumes the largest portion of take-home pay.
- Overseas commitments or family support can materially change what still feels workable each month.
FAQ
What is a comfortable rent percentage?
A common rule of thumb is to keep rent around 30% of take-home income, but what feels comfortable depends on your bills, transport, childcare and savings goals.
Why does this status only show comfortable, tight or risky?
The first version is intentionally simple so the result is easy to understand at a glance, especially on mobile.
Should I include council tax and utilities in bills?
This version gives council tax its own field, and you should also include utility bills for a more realistic monthly housing budget.
What if my rent is above 30% but still feels manageable?
That can happen. The 30% to 35% rule is only a rough guide, so your own transport costs, debts, savings goals and lifestyle still matter.
Can I use salary before tax here?
It is better to use take-home income, because rent affordability is usually about what is left after payroll deductions.
Does this decide what a landlord will accept?
No. Landlords and letting agents may use their own affordability checks, reference standards or guarantor requirements.
