Calculate your DTI ratio and understand your limits

How to calculate DTI ratio for mortgage? To find your Debt-to-Income (DTI) ratio, add up all your monthly debt payments, including mortgage, student loans, car loans and credit card payments. Then, divide that total by your gross monthly income. For example, if you earn $5,000 a month and your total debt payments are $2,000, your DTI would be 40% (2,000 ÷ 5,000 = 0.40 or 40%).

Understanding DTI Ratio

Debt-to-Income ratio, or DTI, is a key number lenders look at when evaluating your mortgage application. It helps them assess how much of your income goes toward paying off debts. A lower DTI suggests you have a healthy balance between debt and income, making you less risky to lend to.

What Counts as Debt?

When calculating your DTI, you need to include all monthly debt obligations. Here’s a quick list of what should be considered:

• Mortgage payments: This includes principal and interest, property taxes and homeowners insurance.
• Car loans: Any monthly payments on vehicles you’re financing.
• Student loans: Monthly payments on education debt.
• Credit cards: Minimum monthly payments, not the total balance.
• Personal loans: Any monthly payments on unsecured loans.

Let’s break this down with a real-world example.

Example: Meet Sarah

Sarah is a 35-year-old teacher in Denver. She makes $5,000 a month before taxes. Here’s how her debts break down:

• Mortgage Payment: $1,500
• Car Loan: $300
• Student Loan: $200
• Credit Card Minimums: $100

Sarah’s total monthly debt payments are $2,100. To find her DTI, you would calculate it like this:

[ \text{DTI} = \frac{\text{Total Debt Payments}}{\text{Gross Monthly Income}} = \frac{2100}{5000} = 0.42 \text{ or } 42% ]

What’s a Good DTI Ratio?

Generally, lenders prefer a DTI ratio below 43%. However, the lower, the better. A DTI of 36% or lower is often seen as ideal. Here’s how DTI affects mortgage eligibility:

• 36% or lower: Likely to qualify for the best rates
• 36% to 43%: May qualify but could face higher interest rates
• Above 43%: More challenging to get approved, might need to pay off some debt first

How to Improve Your DTI Ratio

If your DTI is higher than you’d like, don’t worry. There are several ways to lower it:

Pay off Debt

Look at your debts and see if you can pay down high-interest loans or credit cards. For instance, if Sarah paid off her credit card, her DTI would drop to 40%:

[ \text{New Total Debt Payments} = 1500 + 300 + 200 + 0 = 2000 ] [ \text{New DTI} = \frac{2000}{5000} = 0.40 \text{ or } 40% ]

Increase Your Income

If you can find ways to boost your income, it will automatically improve your DTI. If Sarah took on a part-time job earning an extra $500 a month, her DTI would look even better:

[ \text{New Gross Monthly Income} = 5000 + 500 = 5500 ] [ \text{New DTI} = \frac{2100}{5500} = 0.38 \text{ or } 38% ]

Refinance Existing Debt

Sometimes, refinance can lower your monthly payments. If Sarah refinanced her student loan and reduced her payment from $200 to $150, her DTI would also decrease:

[ \text{New Total Debt Payments} = 1500 + 300 + 150 + 100 = 2050 ] [ \text{New DTI} = \frac{2050}{5000} = 0.41 \text{ or } 41% ]

Different Types of DTI Ratios

Lenders often talk about two types of DTI ratios: front-end and back-end.

Front-End DTI

This ratio includes only housing-related expenses, such as your mortgage, property taxes and homeowners insurance. It’s calculated like this:

[ \text{Front-End DTI} = \frac{\text{Housing Costs}}{\text{Gross Monthly Income}} ]

For Sarah, if her monthly housing costs are $1,500, her front-end DTI would be:

[ \text{Front-End DTI} = \frac{1500}{5000} = 0.30 \text{ or } 30% ]

Back-End DTI

This is the more complete ratio that includes all debts. It’s what we calculated earlier (total monthly debts divided by gross income).

Factors That Affect DTI

While DTI is a big factor in mortgage approval, it’s not the only one. Here are a few other things lenders consider:

Credit Score

A higher credit score can help you get better loan terms, even if your DTI is above 43%. If Sarah has a credit score of 720, she might still qualify for a good rate despite her 42% DTI.

Employment History

Lenders look for stability in your job. If you’ve been at the same job for several years, that can work in your favor, even if your DTI is a bit high.

Savings and Reserves

Having savings can also boost your chances. If Sarah has a solid emergency fund, lenders might overlook a slightly higher DTI.

Real-World Scenarios: More Examples

Example 1: John the Accountant

John is an accountant in Seattle making $6,000 a month. His debts include:

• Mortgage: $1,800
• Car Payment: $400
• Student Loan: $250
• Credit Card: $150

Calculating John’s DTI:

[ \text{Total Debt Payments} = 1800 + 400 + 250 + 150 = 2600 ] [ \text{DTI} = \frac{2600}{6000} = 0.43 \text{ or } 43% ]

John’s DTI is at the upper limit for many lenders, which could mean higher rates.

Example 2: Lisa the Nurse

Lisa is a nurse in Austin earning $4,500 monthly. Here’s her debt:

• Mortgage: $1,200
• Car Payment: $350
• Student Loan: $300
• Credit Card: $50

Calculating her DTI:

[ \text{Total Debt Payments} = 1200 + 350 + 300 + 50 = 1900 ] [ \text{DTI} = \frac{1900}{4500} = 0.42 \text{ or } 42% ]

Lisa’s DTI is just under 43%, which is good for mortgage approval.

Tips for Calculating DTI

1. Keep Records: Track all your debts and monthly payments. Use a spreadsheet or a budgeting app to stay organized.
2. Know Your Income: Make sure you’re using your gross income, which is what you earn before taxes and deductions.
3. Review Regularly: As your debts change, update your DTI calculation. This will help you keep a pulse on your financial health.

FAQs

1. What is a good DTI ratio for mortgage approval?

A good DTI ratio is typically below 36%. Lenders usually prefer ratios under 43%. Lower ratios mean better chances of getting approved and more favorable loan terms.

2. How can I lower my DTI ratio?

To lower your DTI, consider paying down debts, increasing your income, or refinancing for better rates. Every dollar you reduce in debt or add to your income will help improve your ratio.

3. Can I still get a mortgage with a high DTI?

It’s possible, but it’s more challenging. Lenders may require you to have a higher credit score or more savings to offset the risk. You might also face higher interest rates.

4. Does DTI affect my mortgage rate?

Yes, your DTI can influence your mortgage rates. A lower DTI generally leads to better rates, while a higher DTI can result in higher rates or even denial of the loan.

5. Should I include all debts in my DTI calculation?

Yes, you should include all monthly debt obligations like car loans, credit cards and student loans. This gives lenders a complete picture of your financial situation.

Conclusion

Calculating your DTI ratio is a straightforward process that can give you insight into your financial health as you consider applying for a mortgage. Remember to keep your debts in check and seek ways to improve your ratio before applying. If you find your DTI is higher than you’d like, consider paying off some debts or increasing your income.
