Debt-to-Income Ratio Calculator
Your ratios against each loan program's published limits, with the room left in the monthly payment.
What This Calculator Does
Divides the new home's payment (PITI + HOA) and all your monthly debts by gross monthly income, then checks both ratios against each program's published limits and shows the room left in the payment, or how much it would have to drop.
Who Is This For
Buyers getting ready for a pre-approval and realtors pre-screening a buyer before a showing.
How It Works
Enter income, the new home's payment and HOA, and each monthly debt as your credit report shows it. Optional groups hold other income, other homes, support, student loans with a $0 payment and the VA household size.
Frequently Asked Questions
What DTI do lenders accept?
Fannie Mae: 36% manual, up to 45% with the credit score and reserves it requires, 50% through Desktop Underwriter. FHA manual: 31% / 43% up to 40% / 50% with compensating factors. VA: 41%. USDA: 29% / 41%. Automated underwriting can approve higher ratios.
What is the difference between front-end and back-end DTI?
Front-end DTI is the new home's payment divided by gross monthly income; back-end DTI adds every other monthly debt. Utilities, phone, insurance, groceries and the rent you are leaving do not count.
How are student loans with a $0 payment counted?
Fannie Mae: 1% of the balance a month if deferred, $0 on a documented income-driven plan. FHA and USDA: 0.5%. VA: 5% of the balance a year ÷ 12, or nothing if deferred at least 12 months past closing.
What is VA residual income?
What is left of monthly income after taxes, the new payment, debts and upkeep. In the South region, which includes Florida, VA's guideline for a household of four on a loan of $80,000 or more is $1,003 a month; above 41% DTI, 20% more spares the supervisor's justification.
