How this calculator works
Lenders compare your monthly debt payments with your gross monthly income. The housing ratio counts only housing; the total debt-to-income ratio adds every other debt payment.
housing ratio = housing ÷ income × 100, and total DTI = (housing + other debts) ÷ income × 100
- income — gross monthly income before tax
- housing — your monthly rent or mortgage payment
- other debts — minimum payments on cards, loans, and other debts
A total DTI below 36% is comfortable for most lenders, 36% to 43% is acceptable to many, 43% to 50% is tight, and above 50% most lenders decline. Lenders set their own limits, so treat the band as a guide.
What changes your result
Only a few inputs move the number materially. In rough order of impact:
| Input | Effect on the payment | Effect on total cost |
|---|---|---|
| Amount financed | Directly proportional | Directly proportional |
| Interest rate / APR | Directly proportional | Directly proportional |
| Term (months) | Lower payment when longer | Higher total interest when longer |
| Down payment | Lowers the payment | Lowers total interest |
| Trade-in equity | Lowers the amount financed | Lowers total interest |
| Sales tax and fees | Raises the amount financed | Raises total cost |
Enter the rate you were actually offered. This site is not a lender and does not publish rates — a quoted rate is only meaningful next to the term and the amount financed.
