How much house can I afford on my salary?

Use the 28/36 rule: housing (PITI) should not exceed 28% of gross monthly income, and total debts should not exceed 36% of gross income. Example: $75,000 salary = $6,250/month gross. 28% = $1,750 max PITI. That typically supports a home price of roughly $280,000–$350,000 depending on down payment and rates. Use the calculator above for your exact number.

What is the 28/36 rule for mortgages?

The 28/36 rule: (1) Housing costs (PITI—principal, interest, taxes, insurance) should not exceed 28% of gross monthly income (front-end DTI). (2) Total monthly debt payments should not exceed 36% of gross income (back-end DTI). Lenders use these limits to qualify borrowers. Some allow up to 43% back-end.

How much income do I need for a $300,000 mortgage?

For a $300K loan at ~7% over 30 years, P&I is about $2,000/month. With taxes and insurance (~$400–500), PITI is ~$2,500. At 28% front-end DTI you need gross monthly income of about $9,000+, or roughly $108,000+ annually, for a $300K mortgage with no other debt. With other debts, you need more income.

How much house can I afford with $100k salary?

With $100K salary, gross monthly income is $8,333. At 28% front-end, max PITI is about $2,333. With 20% down, 7% rate, 30-year term, and typical tax/insurance, that usually supports a home price of roughly $400,000–$480,000. With existing debt, the affordable price is lower. Use the calculator for your situation.

Should I use gross or net income for mortgage affordability?

Lenders use gross income (before taxes) for the 28/36 rule. Use your annual salary or total taxable income before deductions when using this calculator.

PITI stands for Principal, Interest, Taxes, and Insurance—your total monthly housing payment. Principal and interest are the loan payment; taxes are property taxes; insurance is homeowners insurance. Lenders use PITI for the 28% front-end DTI limit.

How We Calculate It

28% rule (front-end): Your housing payment (PITI) should not exceed 28% of your gross monthly income.

36% rule (back-end): Your total monthly debts (housing + car, student loans, etc.) should not exceed 36% of gross income. We use the lower of the two limits to stay within lender guidelines.

Max home price is derived from your max affordable PITI, loan term, interest rate, and estimated property tax and insurance.

How We Calculate Affordability

28% Rule (Front-End DTI)

Your monthly housing payment (PITI: principal, interest, taxes, insurance) should not exceed 28% of your gross monthly income. Example: $6,000 income × 28% = $1,680 max PITI.

36% Rule (Back-End DTI)

Your total monthly debts (housing + car, student loans, credit cards, etc.) should not exceed 36% of gross income. We use the lower of the two limits so you stay within lender guidelines.
