Yes, your debt-to-income ratio includes taxes and insurance. When a lender calculates DTI for a mortgage, the housing payment they plug into the ratio is not just principal and interest. It is PITI: principal, interest, property taxes, and insurance, bundled into one monthly figure.1Consumer Financial Protection Bureau. What Is PITI? Homeowners insurance is always in there. Mortgage insurance is in there if your loan requires it. Flood insurance is in there if the property needs it. HOA or condo dues get added on top. All of it counts against your income before the lender decides whether you qualify.
What Counts as Your Housing Payment
The front-end DTI ratio, sometimes called the housing ratio, measures your total monthly housing costs against your gross monthly income. Fannie Mae’s automated underwriting adds principal, interest, taxes, insurance, mortgage insurance, and HOA dues together, then divides by income to produce that ratio.2Fannie Mae. DU Job Aids – DTI Ratio Calculation Questions Every one of those components is a required cost of owning the specific home you are buying, which is why the lender treats them as housing rather than as optional spending.
The back-end ratio then takes that same housing figure and adds your other recurring debts on top: credit card minimums, auto loans, student loans, personal loans, child support, alimony, and payments on any other properties. Both ratios carry the full taxes-and-insurance load. Skipping those numbers when you estimate affordability is the fastest way to be surprised at underwriting.
Property Taxes in the Calculation
Your lender takes the annual property tax bill from the local tax authority, divides by twelve, and adds that amount to your monthly payment.2Fannie Mae. DU Job Aids – DTI Ratio Calculation Questions For a newly built home with no tax history, the lender estimates the annual taxes, often as a percentage of the purchase price.
Location matters a lot here. Effective property tax rates range roughly from 0.27 percent to over 2 percent of a home’s value. On a $350,000 home, that spread can mean anywhere from about $50 to $650 added to the monthly housing payment. The DTI treats both figures the same way: whatever the tax bill divides down to, that number goes in.
Many lenders collect the tax through an escrow account and pay the bill when it comes due.1Consumer Financial Protection Bureau. What Is PITI? Whether you escrow or pay the tax yourself, the amount still counts toward your DTI. Unpaid property taxes can create a lien that outranks the mortgage, which is part of why lenders build the tax into the qualifying payment.3Internal Revenue Service. 5.17.2 Federal Tax Liens
Insurance in the Calculation
Several kinds of insurance can land in the monthly housing payment, and each one counts toward DTI. The annual premium is divided by twelve to produce a monthly figure.
Homeowners Insurance
Standard homeowners coverage, sometimes called hazard insurance, protects the property against fire, storms, theft, and similar risks. Lenders require it before closing. Premiums vary widely, typically from about $600 to over $10,000 per year depending on the state, home value, and risk factors. That translates to roughly $50 to $850 per month added to the housing side of the ratio.
Flood Insurance
If any part of the home sits in a Special Flood Hazard Area, the lender will require flood insurance before the loan can close. Fannie Mae requires flood coverage whenever the principal structure is in an SFHA, and the loan is not eligible for purchase if the community does not participate in the National Flood Insurance Program.4Fannie Mae. Flood Insurance Requirements for All Property Types Even when it is not required, FEMA recommends coverage in moderate-risk areas, and any premium you carry gets folded into DTI.5FEMA.

Private Mortgage Insurance
Put less than 20 percent down on a conventional loan and the lender will require private mortgage insurance.6Consumer Financial Protection Bureau. What Is Private Mortgage Insurance? PMI typically costs between 0.46 and 1.50 percent of the original loan amount per year. On a $300,000 loan, that is roughly $115 to $375 per month added to your housing payment and, therefore, to your DTI.
PMI is not permanent. Your servicer must automatically cancel it once your loan balance reaches 78 percent of the original property value based on the payment schedule, and you can request cancellation at 80 percent loan-to-value if your payment history is clean, with no late payments of 30 days or more in the past year.7Fannie Mae. Termination of Conventional Mortgage Insurance When PMI comes off, the monthly payment drops and DTI improves.
FHA Mortgage Insurance Premium
FHA loans use a different structure. You pay an upfront mortgage insurance premium at closing, currently 1.75 percent of the loan amount, and an annual premium collected in monthly installments.8U.S. Department of Housing and Urban Development. What Is the FHA Mortgage Insurance Premium Structure for Forward Mortgage Loans The annual MIP rate runs from 0.15 percent to 0.75 percent depending on your loan term, loan amount, and loan-to-value ratio. Unlike conventional PMI, FHA mortgage insurance generally cannot be canceled and stays for the life of the loan if you put less than 10 percent down. The monthly MIP counts toward DTI the whole time.
HOA and Condo Dues
If the property sits in a homeowners association or condo association, the mandatory dues are pulled into the front-end housing ratio.2Fannie Mae. DU Job Aids – DTI Ratio Calculation Questions Quarterly or annual bills get converted to a monthly figure. Failing to pay HOA dues can produce a lien on the home and, in some areas, foreclosure by the association, so lenders treat them as a fixed obligation of owning that specific property.
What Does Not Count
Utilities, cell phone bills, internet, groceries, health insurance premiums, car insurance, and subscriptions are excluded from DTI.9Fannie Mae. Why Understanding Debt Is Essential Lenders classify these as living expenses, not debt obligations. That gap is worth understanding on your own end: two borrowers with the same DTI can have very different money left over after the bills that DTI ignores.
Credit card balances do not count in full either. What goes into DTI is the minimum monthly payment on the statement, not the total balance owed.
The Income Side
DTI uses gross monthly income as the denominator, meaning income before taxes, retirement contributions, health insurance, and other paycheck deductions.10Fannie Mae. Mortgage Affordability Calculator Base salary and hourly wages are standard, but bonuses, overtime, commissions, rental income, and self-employment earnings can also count. Variable income like bonuses and overtime generally needs at least a 12-month track record, with a two-year history the standard recommendation.11Fannie Mae. Base Pay (Salary or Hourly), Bonus, and Overtime Income
Because the ratio uses gross rather than take-home pay, DTI often looks healthier on paper than the budget feels. A borrower earning $7,000 gross may take home closer to $5,200 after deductions, and the housing payment the lender approves is based on the larger figure.
DTI Limits by Loan Program
Each loan program sets its own thresholds, and the taxes-and-insurance-loaded housing figure is measured against them.
- Conventional (Fannie Mae), manual underwriting: total DTI up to 36 percent, stretching to 45 percent with higher credit scores and reserves.12Fannie Mae. Debt-to-Income Ratios
- Conventional (Fannie Mae), automated underwriting through DU: total DTI up to 50 percent.12Fannie Mae. Debt-to-Income Ratios
- FHA: generally 31 percent front-end and 43 percent back-end, with room up to 50 percent back-end when compensating factors like strong credit or significant savings are in play.
- VA: 41 percent back-end as a benchmark rather than a hard cap; strong residual income can support approval above that figure.
The old 43 percent Qualified Mortgage cap no longer applies as a fixed number. The CFPB’s General QM definition uses a price-based test tied to the average prime offer rate instead.13CFPB. General QM Loan Definition Final Rule The individual program limits above still apply.
How to Bring Your DTI Down
If the housing payment inflated by taxes and insurance pushes your ratio above your target program’s limit, a few moves help:
- Pay down existing debt. Reducing a credit card balance, car loan, or personal loan drops the debts on the back end. Target debts with a high monthly payment relative to the remaining balance.
- Avoid new debt before applying. Financing a car or opening a new credit line right before a mortgage application raises the ratio at the worst moment.
- Increase income. A raise, a side job, or a co-borrower with stable income lifts the denominator. Variable income needs documented history, so plan ahead.
- Choose a less expensive home. A smaller loan pulls down principal, interest, taxes, insurance, and possibly PMI all at once.
- Make a larger down payment. Twenty percent down eliminates PMI on a conventional loan and shrinks the loan amount, which lowers every part of PITI.
Small changes shift the ratio more than people expect. Paying off a $200 car payment cuts back-end DTI by roughly three percentage points on a $6,000 gross monthly income. Cutting a similar amount from the tax or insurance side, by shopping insurance or buying in a lower-tax area, moves the housing ratio the same way.
