3× Rent Calculator

What is the 3x rent rule?

The 3x rent rule is a screening heuristic used by many U.S. landlords: gross monthly income should be at least three times the monthly rent. It's the inverse framing of the 30% rule: if rent is one-third of gross income, the landlord sees 3x coverage on a single paycheck.

Landlords usually verify this through pay stubs, an offer letter, W-2s, or recent tax returns. Gig and self-employed income is harder to verify, so landlords often ask for two months of bank statements instead. If you want to look at the same math from the other direction, the rent-to-income calculator shows what percentage of your income a given rent would actually take up.

Why landlords use it

It's a fast, conservative way to estimate whether you'll be able to make rent each month even when life happens. It isn't a law and isn't universal: some markets use 2.5x, luxury buildings often go higher, and corporate landlords sometimes have stricter internal scoring. For the full breakdown of how the 3x rule fits alongside the 30% rule, the emergency fund convention, and the readiness score, see our methodology.

What to do if you don't meet 3x

• Apply with a co-signer or guarantor
• Offer a larger security deposit or prepay a month or two of rent
• Apply with a roommate so combined income clears the bar
• Provide documentation of savings: many landlords flex if you have 6+ months of rent in the bank
• Look at smaller landlords or rent-by-room listings, which often use looser rules
