28/36 Debt-to-Income (DTI) Affordability Rule
Transparent mathematical methodology explained in plain English.
Max Monthly Payment = min(GrossIncome × 0.28, GrossIncome × 0.36 - Debts)Evaluates your maximum recommended housing budget using the standard 28% front-end and 36% back-end underwriting thresholds.
Variables Explained:
- GrossIncome: Gross monthly household income before taxes.
- Debts: Total monthly recurring minimum debt obligations.
$90,000 Household Income with $450/mo Recurring Debt
Calculating maximum home purchase budget with 20% down at 6.75% mortgage rate.
- Gross monthly earnings: $90,000 / 12 = $7,500.
- Front-end limit (28%): $7,500 × 0.28 = $2,100/mo.
- Back-end limit (36%): ($7,500 × 0.36) - $450 = $2,250/mo.
- Allowable principal & interest + escrow payment: $2,100/mo.
- Supported loan principal: ~$280,000.
- Total purchase purchasing power: $280,000 + $40,000 = $320,000.

What is the 28/36 rule in loan affordability?
The 28/36 rule is an underwriting standard stating that household housing costs should not exceed 28% of gross monthly income, and total debt payments (housing + credit cards + auto + student loans) should not exceed 36%.
How does down payment affect affordability?
A larger down payment directly increases total purchasing power dollar-for-dollar and lowers loan-to-value (LTV), which can eliminate private mortgage insurance (PMI) fees.
