Quick Tool Overview

The Rent Calculator gives a rent you can comfortably afford, checked two ways: against the thirty percent of gross income guideline, and against what is genuinely left once your real expenses are paid. It also shows the cash needed to move in.

About the Rent Calculator

Enter your income and your other monthly commitments to get a rent range you can comfortably carry, checked against both the thirty percent rule of thumb and the income multiple landlords typically screen for, which is usually forty times the monthly rent.

The thirty percent guideline is a starting point, not a law, and it works badly at the extremes. On a low income, thirty percent can still leave too little for everything else; on a high one, it may be more than you would ever sensibly spend. The calculator therefore also works from what is actually left after your real expenses, which is the more honest test, and it flags the up-front cash you need for a deposit and first month before you can move in at all.

Key features of the Rent Calculator

Two tests, not one

The thirty percent rule alongside what your actual budget supports, because the rule works badly at both extremes.

Landlord screening check

Most landlords want annual income of forty times the monthly rent, so the calculator flags whether you clear it.

Move-in cash calculated

Deposit plus first month, and often last month, is due before you get the keys.

Gross and take-home

Landlords screen on gross; you live on net. Both are shown because they answer different questions.

Shared leases supported

Add a partner or roommate income to see the combined budget.

Frequently asked questions

A guideline that housing should take no more than thirty percent of gross income. It is a useful benchmark but ignores debts, location and lifestyle, so treat it as one input rather than the answer.
