The 30% rule is a general guideline. Your actual affordability depends on local cost of living, lifestyle, and financial goals. Landlords typically require income of 2.5-3× the rent. This is not financial advice.

Top: one $6,000 gross month split into rent, debt, savings, other spending and what is left. The shaded band is everything up to the 30% guideline. Bottom: the same $6,000 converted into a rent cap ladder, where the 25–30% band is the comfortable zone and the 50% rule is the hard ceiling once debt payments are subtracted.

Worked example

Maya earns $6,000 a month gross, pays $500 a month across a car loan and a student loan, wants to bank $600 a month, and spends roughly $800 on food, transport, insurance and utilities. She is looking at a one-bedroom listed at $1,800 a month.

  1. 30% rule:$6,000 × 0.30 = $1,800/mo. Her target rent lands exactly on the guideline, so the tool reports it as affordable rather than tight.
  2. 50% rule after debt:($6,000 × 0.50) − $500 = $2,500/mo. That is the absolute ceiling once her existing debt payments are taken out first.
  3. Share of income:$1,800 ÷ $6,000 = 30.0% of gross income, and rent plus debt is $2,300 ÷ $6,000 = 38.3% — still under the 43% ceiling most lenders screen against.
  4. What is left:$6,000 − $1,800 rent − $500 debt − $600 savings − $800 other = $2,300/mo of free cash flow, which is the same number the Breakdown row shows as "Remaining after 30% rent".
  5. Income needed:$1,800 × 12 ÷ 0.30 = $72,000/yr. If her income were lower than that, this rent would push her past the 30% guideline.

What Is the Rental Affordability Calculator?

This calculator determines how much rent fits your finances using three lenses at once: the classic 30% rule dividing gross income, a debt-to-income approach that accounts for your actual loan payments, and a cash-flow view that subtracts real monthly obligations before declaring a number comfortable. Enter income, debts, and target rent, and the tool returns your affordable range, the percentage each option consumes, and a verdict on whether the specific apartment you're eyeing fits. High-cost-market adjustments are built in — the strict 30% rule was calibrated in a cheaper era, and in 2026 metros the tool shows what stretching to 35–40% costs elsewhere in your budget.

Who Should Use This Tool?

Renters setting a ceiling before apartment hunting avoid falling in love above their number. Roommates splitting rent compute the income combination that makes a place work — two incomes at different levels, with the split set accordingly. Relocators compare salary-adjusted affordability across metros before accepting an offer. Landlords and agents pre-qualify honestly with applicants using the same standards landlords themselves apply (many require income at 2.5–3× rent). Anyone renewing a lease against a rent increase tests whether the new number still clears their thresholds.

How Does It Work?

(1) Enter gross monthly income — combined household income if applicable. (2) Add monthly debt obligations: car loans, student loans, credit card minimums, other recurring debt. (3) Optionally enter your target rent to test it directly. (4) Read the results: maximum rent under the 30% rule, the DTI-adjusted figure that reserves room for debts, and a comfortable range; the target test shows what percentage of income your chosen rent consumes and flags the threshold it crosses.

Is the 30% Rent Rule Still Realistic?

The rule descends from 1980s housing policy — a threshold above which a household was considered cost-burdened — and it assumed a cheaper housing market. In 2026, renters in high-cost metros routinely exceed it: median one-bedroom rents push the 30% line past $2,200 in many coastal cities, which requires $88,000+ income, well above typical local median earnings. HUD itself acknowledges the strain by using an adjusted standard — 40% of adjusted income for some assistance programs. Workable modern practice: treat 30% as a floor for comfort and 40% as the practical ceiling, then apply two overrides. First, the DTI view: with significant student or car debt, even 30% of gross can crowd out savings — compute affordability after debts, not before. Second, the savings floor: whatever the percentage, if rent prevents contributing to retirement and a three-month emergency fund, it is unaffordable at any ratio. This calculator shows all three lenses precisely because no single rule survives contact with a real budget.

Frequently Asked Questions

How much of my income should go to rent?

The classic benchmark is 30% of gross income — above it, HUD considers a household cost-burdened. Modern budgeting (the 50/30/20 rule) treats rent as part of the 50% needs bucket, so in a high-cost city where rent alone eats 35-40%, you compensate by keeping other needs lean. This calculator shows both the 30% benchmark and what your stated debts leave as realistic ceiling.

Does existing debt change what I can afford?

It has to. Landlords and mortgage underwriters both look at debt-to-income: a car loan, student loans, and card minimums come out of the same paycheck. Earning $6,000/month with $1,200 in debt payments supports far less rent than the same income debt-free — which is why the calculator subtracts monthly obligations before applying the rent-to-income ratio.

What income do landlords actually verify?

Standard screening looks for gross household income of 2.5-3x the monthly rent, documented via pay stubs, offer letters, or tax returns; self-employed applicants usually show 2 years of returns or bank statements. A guarantor (often needing 4-5x) or a larger upfront payment can bridge a shortfall. Knowing the 3x screen explains why the 'affordable' number here may still get your application declined in competitive markets.

Should I compute affordability on gross or net income?

Landlords screen on gross, but your actual budget lives on net — take-home pay after taxes and deductions. The gap is large (often 25-30%). Use gross to know which listings will pass screening, then sanity-check the rent against net so the payment does not crowd out savings. This calculator keeps both views honest rather than letting a pre-tax number flatter the budget.

How much rent can I afford based on my income?

The 30% rule: your gross monthly income should be at least 3x the monthly rent. On $5,000/month income, you can afford up to $1,667 rent. However, high-debt individuals should use the 28/36 rule: housing costs should not exceed 28% of gross monthly income, and total debt payments (including rent) should not exceed 36%.

Does it account for debts and other expenses?

Yes. Enter your monthly debt payments (student loans, car payment, credit card minimums) and the tool calculates your debt-to-income ratio (DTI). A DTI above 36% may disqualify you from many rentals. It also shows a "comfortable" rent range (25% of income) versus the maximum (35% of income).
