If you’ve started looking into buying a home, you’ve probably heard the term debt-to-income ratio, or DTI. It’s one of the most important numbers lenders look at when deciding whether to approve your mortgage, and understanding it can help you get prepared before you ever apply.
What Is Debt-to-Income Ratio?
Your debt-to-income ratio is the percentage of your gross monthly income that goes toward paying debts. Lenders use it to measure your ability to manage monthly payments and repay what you borrow.
Here’s how to calculate it: add up all your monthly debt payments (car loans, student loans, credit cards, and any other recurring obligations), divide that total by your gross monthly income, and multiply by 100.
Example: If you earn $6,000 per month and your monthly debts total $1,800, your DTI is 30%.
What DTI Do Lenders Want to See?
Different loan types have different requirements, but here are some general guidelines:
- Conventional loans: Most lenders prefer a DTI of 43% or lower, though some will go up to 50% with strong compensating factors.
- FHA loans: FHA allows DTIs up to 57% in some cases, making it a popular option for buyers with higher debt loads.
- VA loans: The VA doesn’t set a hard cap, but most lenders look for 41% or below.
Two Types of DTI
Lenders actually look at two numbers:
Front-end DTI covers only your housing costs (mortgage payment, taxes, insurance, and HOA fees if applicable) as a percentage of your income. Most lenders want this below 28%.
Back-end DTI includes all your monthly debts plus your new housing payment. This is the number most lenders focus on.
How to Improve Your DTI Before Applying
- Pay down existing debt, especially credit cards and car loans
- Avoid taking on new debt before applying
- Look for ways to increase your income
- Consider a co-borrower whose income can help lower the ratio
