Rent affordability calculator

Compare monthly rent and utilities with gross income and a target housing-cost ratio.

What this calculator covers

Use this rent affordability calculator to measure how a proposed rent and utility load compares with gross income and a target housing-cost ratio.

The walkthrough keeps the current rent burden, the budget gap, and the implied income target visible together so the result can support budgeting and lease-comparison decisions.

Frequently asked questions

What is rent burden?
Rent burden is the share of gross income consumed by housing costs — typically rent plus utilities. A housing-cost ratio above 30% is often described as cost-burdened, though the right threshold depends on your total financial picture, debt load, and local cost of living.
Why does this use gross income rather than take-home pay?
Many affordability guidelines and landlord income requirements are stated as multiples of gross income, so using pre-tax income keeps the result comparable with those benchmarks. Take-home pay varies significantly depending on tax situation, so gross income is the more consistent basis for comparison.
What is the "required income" figure?
It is the gross annual income that would make your current housing cost fall at or below the target housing ratio you entered. If your actual income is below that figure, the current rent exceeds your target threshold and the gap shows how far below the target you are.
Does this include all housing costs?
The model adds rent and utilities together as the housing-cost bucket. Other recurring ownership-adjacent costs such as renters insurance or parking are not included unless you fold them into one of those fields manually.

$2,350.00 of monthly rent and utilities against $8,000.00 of gross monthly income produces a housing-cost ratio of 29.38%.

Housing cost ratio
29.38%
Total monthly housing cost
$2,350.00
Affordable monthly budget
$2,400.00
Monthly gap to target
$50.00
Required annual income
$93,999.96

Step-by-step solution

  1. 1.Add rent and utilities to estimate a total monthly housing cost of $2,350.00.
  2. 2.Compare that housing cost against gross monthly income to measure a housing-cost ratio of 29.38% against the 30% target.
  3. 3.Translate the target ratio back into income, which implies about $93,999.96 of annual income or about $45.19 per hour at 40 hours per week.

Walkthrough

Visual walkthrough

Rent affordability works best as a budget check: compare your monthly housing cost against gross income, then measure how much room is left or missing.

  1. 01

    Build the monthly housing cost

    $2,100.00 + $250.00 = $2,350.00

    Utilities are kept separate so rent alone does not hide the real monthly housing burden.

  2. 02

    Compare cost against income

    $2,350.00 ÷ $8,000.00 = 29.38%

    This turns the monthly cost into a share of gross income so it is easy to compare against a target budget ratio.

  3. 03

    Translate the target into income needed

    If the rent is above the target ratio, the required income shows the level needed to bring that same housing cost back down to the chosen threshold.
