How Mortgage Affordability Is Calculated

Lenders use your income, debts, and the 28/36 rule to determine how much they will lend you. Here is exactly what goes into the math.

The 28/36 Rule

This is the standard guideline used by most conventional lenders. Front-end: Your total monthly housing cost (mortgage P&I + taxes + insurance + PMI + HOA) should not exceed 28% of your gross monthly income. Back-end: All monthly debt payments (housing + car + student loans + credit cards) should not exceed 36%.

Max Housing Payment (28% Rule)
Max Housing = Gross Monthly Income × 0.28
Example: $100,000/yr ÷ 12 = $8,333/mo gross
Max housing: $8,333 × 28% = $2,333/month
Max all debt (36%): $8,333 × 36% = $3,000/month

From Payment to Home Price

Once we know the maximum monthly P&I payment, we use the inverse amortization formula to find the maximum loan amount, then add your down payment to get the maximum home price.

Max Loan Amount Formula
P = M × [(1+r)ⁿ − 1] / [r(1+r)ⁿ]
M = Max P&I payment (from 28% rule minus taxes/ins/PMI/HOA)
r = Monthly rate (annual rate ÷ 12)
n = Loan term in months
Max Home Price = P ÷ (1 − down payment %)

What Loan Type Changes

FHA allows up to 43% back-end DTI (some lenders 50%). VA and USDA focus on residual income rather than strict DTI ratios. Our calculator applies the most accurate rules per loan type.

Conventional, FHA, VA & USDA — Which Is Best for Your Budget?

The loan type you choose changes your minimum down payment, PMI requirements, credit score threshold, and maximum DTI allowed.

Conventional Loans

Not government-backed. As little as 3% down with PMI. Best rates for 740+ credit and 20%+ down. 2026 conforming limit: $806,500 (most counties). Max DTI typically 36–45%.

FHA Loans

Backed by the FHA. 3.5% down with 580+ credit score, or 10% down with 500–579. MIP required for the life of the loan if down payment <10%. Max DTI up to 43–50% in some cases.

VA Loans

For eligible veterans and active-duty service members. No down payment, no PMI. No official credit minimum (most lenders require 620+). Lenders look at residual income rather than a strict DTI cap.

USDA Loans

For rural and some suburban areas. No down payment required. Income limits apply (typically 115% of area median income). Requires 640+ credit score. 1% upfront guarantee fee and 0.35% annual fee.
