Excellent

Back-end DTI (all debt)

Total monthly debt

$1,800

Monthly gross income

$7,000

$84,000 / year

Headroom to 28% front-end

$160

Extra housing you can add before hitting 28%

Headroom to 36% back-end

$720

Mortgage qualification tiers

Conventional (front-end ≤ 28%)
Conventional (back-end ≤ 43%)
FHA (back-end ≤ 43%)
FHA with compensating factors (≤ 50%)
VA loan (back-end ≤ 41% guideline)

Qualification depends on credit score, reserves, and lender guidelines. These are general thresholds, not guarantees.

Show the math

Front-end DTI covers only housing costs. Back-end DTI adds all other monthly debt. Both are divided by your gross monthly income to get the ratios lenders evaluate.

Front-end DTI = $1,800 housing ÷ $7,000 gross = 25.7%

Back-end DTI = ($1,800 + $0 other debts) ÷ $7,000 = 25.7%

You have $160 of headroom before hitting the 28% front-end threshold and $720 before hitting 36% back-end — the two limits most conventional lenders use.
