The average new-car buyer now signs up for a $787 monthly payment, a record, according to Edmunds. If you plan to buy a home in the next few years, that payment does double damage: at today’s 7.11% mortgage rate, $787 a month is the same as about $117,000 of mortgage you could otherwise qualify for.

That is not a scare number. It is how lenders’ debt-to-income math works. Here is the exact calculation and what it means at different incomes.

Quick answers

Average new-car payment: $787/month in Q3 2026; used cars $582 (Edmunds).
Mortgage rate used: 7.11% on a 30-year fixed (Freddie Mac, Nov. 12, 2026).
The swap rate: every $100 of monthly debt equals about $14,900 of mortgage at 7.11%.
$787 car payment ≈ $117,000 of borrowing power. $582 ≈ $86,500.
Who gets hit hardest: households earning $60,000–$90,000, where the debt limit, not income, decides the budget.

The record-breaking car loan, in numbers

Edmunds’ Q3 2026 financing report found new-car buyers financed an average $44,664 at a 7.0% APR over about 70.5 months. Loans of 84 months or longer hit a record 25.5% of new-vehicle financing, and 21.2% of buyers took on payments of $1,000 or more.

Multiply it out: $787 a month for 70.5 months is about $55,500 in payments for one car.

Why a car payment shrinks your mortgage

Mortgage lenders look at your debt-to-income ratio (DTI). A common guideline is the 28/36 rule: housing costs up to about 28% of gross monthly income, and all debts together up to about 36%. Some loan programs allow a higher total DTI, but the logic is the same: every dollar going to a car lender is a dollar that cannot go to a mortgage.

At 7.11% on a 30-year loan, $1 of monthly principal and interest supports about $148.65 of loan. So:

Monthly car payment	Mortgage it “uses up” at 7.11%
$300	about $44,600
$582 (avg used car)	about $86,500
$787 (avg new car)	about $117,000
$1,000	about $148,700

Fun factAt last year’s 6.24% rate, the same $787 equaled about $128,000 of mortgage. Higher rates mean each dollar of payment buys less house, so the car “costs” a bit less loan today, but your total budget is also smaller.

What it does to real budgets

We ran four household incomes through the 28/36 rule, assuming $500 a month for property taxes and insurance and no other debts besides the car. Loan amounts are what the leftover payment supports at 7.11%.

Household income	Max loan, no car payment	Max loan with $787 car payment	Buying power lost
$60,000	$133,800	$76,300	−$57,500
$75,000	$185,800	$143,200	−$42,700
$90,000	$237,800	$210,000	−$27,800
$120,000	$341,900	$341,900	$0

At $120,000 the car payment still fits under the 36% cap, so the 28% housing limit is what decides the budget. Below that, the car eats straight into the house. A $60,000 household loses about 43% of its borrowing power.

Myth buster“I’ll pay off the car after I buy the house.” The lender counts the payment at application. If the car loan has many months left, it counts in full. A loan with only a few payments left may be treated differently, so ask your lender how they count it.

What to do if a home is your next big goal

Delay the car, not the house: if your current car runs, keeping it 12–18 more months while you save can protect tens of thousands of buying power.
Buy cheaper or used: dropping from $787 to $400 a month restores roughly $57,500 of mortgage room at 7.11%.
Pay down before you apply: lowering the balance can lower the payment, and some lenders may exclude a loan that is almost paid off.
Avoid 84-month loans: they lower the payment but keep it on your credit report for seven years, right through your home search.
Check your numbers first: run your DTI in the DTI calculator, then see your price range in the home affordability calculator.

ExampleJordan earns $75,000 and wants a home next year. Without a car loan, the 28/36 rule supports a loan of about $185,800. If Jordan signs a $787 car payment this month, that drops to about $143,200. Keeping the old car one more year keeps about $42,700 of buying power on the table.

What this means for you

Renters saving to buy: treat any new car loan as a direct trade against your future home price.
Couples: lenders add both partners’ debts. Two car payments can cut buying power twice.
Higher earners: you may have room, but a big payment still raises your DTI and can affect the rate or loan options you get.

FAQ

Does a lease count the same as a car loan?

Lenders generally count lease payments as monthly debt too, so a lease reduces buying power in the same way.

Is 36% the maximum DTI?

No. It is a common guideline. Many loan programs allow higher total DTI with strong credit or savings, but a higher DTI also means a tighter monthly budget.

Should I pay off my car before applying for a mortgage?

It can help if it frees up a large payment, but do not drain the cash you need for the down payment, closing costs and reserves. Run both versions with a lender.

Does buying a car hurt my credit score before a mortgage?

A new loan adds a hard inquiry and a new account, which can lower scores a little for a while. Most experts suggest avoiding new credit right before and during a home purchase.
