Show the math

A common budgeting guideline caps rent at a share of gross income:

max rent = gross monthly income × ratio%

The 30% rule is a starting point, high-cost areas often push higher, while heavy debt argues for less. Many landlords also want income of at least 3× the rent. Everything is calculated locally in your browser.

What this does

A rent affordability calculator finds the monthly rent you can comfortably afford from your income using the 30% rule (or your own ratio), plus the income a landlord’s 3× rule implies.

How it works

A common guideline caps rent at about 30% of gross monthly income. Many landlords separately require income of at least three times the monthly rent.

Max rent = gross monthly income × ratio

How to use it

  1. Enter your gross monthly income.
  2. Adjust the affordability ratio if needed.
  3. Read your maximum affordable rent.
  4. See the income the 3× rule implies.

Understanding your result

The 30% guideline traditionally uses gross (pre-tax) income. If you prefer to budget on take-home pay, lower the ratio accordingly.

Example

At 30% of a $5,000 monthly income, comfortable rent is about $1,500.
