Formula used

The 28/36 rule

The front-end ratio caps the full housing payment — principal, interest, taxes, insurance, PMI and HOA — at 28% of gross monthly income. The back-end ratio caps that payment plus every other monthly debt obligation at 36%. Your budget is whichever of the two binds first, which for most buyers with a car payment is the back-end test.

Housing ≤ 28% of gross monthly income • Housing + all other debt ≤ 36% of gross monthly income
Front-end ratio cap
28% of gross
Back-end ratio cap
36% of gross
Conventional max DTI
Often up to 45–50%
FHA max DTI
Often up to 57% with compensating factors

Approved for is not the same as afford

Lenders routinely approve DTIs of 45% and above with strong credit and reserves. The 28/36 rule is the conservative version, and it is closer to what leaves room for retirement contributions, childcare, and a life. The gap between the two numbers is where house-poor households come from.

Paying off a car often beats saving more

A $500 car payment consumes $500 of your 36% allowance, which translates to roughly $75,000–$80,000 of purchase price at current rates. Saving an extra $10,000 for the down payment moves the price by about $10,000. If you can clear an instalment loan before applying, that is almost always the bigger lever.

What counts in the debt figure

Minimum credit card payments, car loans, student loans (the reported payment, or a percentage of balance if deferred), personal loans, child support and alimony. Not included: utilities, insurance, groceries, phone bills or anything not reported to credit bureaux.

Down payment size changes the answer twice

More cash down reduces the loan, which lowers the payment, and crossing 20% removes PMI entirely. Between 15% and 20% down there is often a step change in affordability that is larger than the cash difference alone — worth modelling both sides before committing.

FAQ

How much house can I afford on $110,000 a year?

Under the 28/36 rule, about $2,567/month for housing before other debts. With $650/month of other debt and $60,000 down at 6.75%, that supports roughly a $380,000–$400,000 home depending on local tax rates. Enter your figures above for the exact number.

What is the 28/36 rule?

Spend no more than 28% of gross monthly income on housing, and no more than 36% on housing plus all other debt payments. It is the traditional underwriting guideline and a reasonable conservative ceiling.

Does the calculator include property taxes and insurance?

Yes. The 28% cap covers the full payment: principal, interest, taxes, insurance, PMI where applicable, and HOA dues. Calculators that only test principal and interest overstate affordability significantly.

How much do I need for a down payment?

Conventional loans go as low as 3%, FHA 3.5%, and VA and USDA can be zero. Below 20% you pay PMI, which typically adds 0.5–1% of the loan per year until you reach 20% equity.
