A lender may approve you for far more house than you can comfortably carry. That gap is the real answer to "how much house can I afford?" And it's bigger than most buyers expect.

The classic test is the 28/36 rule. It caps housing at 28% of gross income and all debt at 36%. So on a $100,000 salary, that's about $2,333 a month for housing. At today's rates, it buys roughly a $335,000 home.

But today's rates matter a lot. Freddie Mac put the average 30-year fixed rate at 7.40% on October 8, 2026. That's up from 6.30% a year earlier. As a result, every salary buys less house than it did last fall.

Below, you'll find the 28/36 rule by salary, from $50,000 to $200,000. You'll also see the lender-maximum numbers, the debt line that quietly shrinks your budget, and a take-home check. To run your own numbers, our free Mortgage Affordability Calculator does the math in seconds.

How much house can I afford on my salary?

TL;DR:

β€” Under the 28/36 rule, most buyers can afford a home priced at about 3 to 3.5 times their gross salary. For example, at Freddie Mac's 7.40% average (October 8, 2026), a $100,000 salary supports roughly a $335,000 home with 20% down. That assumes no other debts and typical property taxes and insurance.

In other words, your home buying power rises a little faster than your income. That's because insurance is a fixed cost, so it eats a bigger share of a smaller budget. Still, treat these figures as a starting price range, not a promise of how much house you can afford.

What is the 28/36 rule?

The 28/36 rule is a home affordability guideline built on two debt-to-income ratios. First, your housing payment should stay at or below 28% of gross monthly income. Second, all your debt payments, housing included, should stay at or below 36%.

Lenders call these the front-end and back-end ratios. Here, the housing payment means PITI: principal, interest, property taxes, and homeowners insurance. It also includes PMI and HOA dues when you have them.

Where do the numbers come from? The Consumer Financial Protection Bureau suggests homeowners consider keeping total debt at 36% of income or less. Yet the same guide notes that some lenders go to 43% or higher. Similarly, Fannie Mae's consumer site suggests housing costs of about 25% to 30% of gross income.

However, actual lending limits run higher. Here's how the main programs compare:

Loan programHousing capTotal-debt capSource
Conventional, manual reviewβ€”36%, up to 45%Fannie Mae
Conventional, automated (DU)β€”Up to 50%Fannie Mae
FHA31%43%HUD
VAβ€”41% guidelineVA (38 CFR 36.4340)

According to the Fannie Mae Selling Guide, manually underwritten loans max out at 36%. That limit can rise to 45% with strong credit and cash reserves. Meanwhile, loans run through Desktop Underwriter can reach 50%. So 28/36 is a comfort target, not a legal ceiling.

How much house can I afford by salary?

Here's the 28/36 rule by salary at today's rates, so you can see how much house you can afford at each income level. Each price assumes a 30-year fixed loan at 7.40%, 20% down, and property tax of 1% of the price per year. It also assumes $200 a month for homeowners insurance and no other debts.

Annual salary28% housing cap36% total-debt capHome price you can afford
$50,000$1,167/mo$1,500/mo~$152,000
$60,000$1,400/mo$1,800/mo~$188,000
$75,000$1,750/mo$2,250/mo~$243,000
$90,000$2,100/mo$2,700/mo~$298,000
$100,000$2,333/mo$3,000/mo~$335,000
$125,000$2,917/mo$3,750/mo~$426,000
$150,000$3,500/mo$4,500/mo~$518,000
$175,000$4,083/mo$5,250/mo~$609,000
$200,000$4,667/mo$6,000/mo~$701,000

Notice that the price-to-income multiple climbs from about 3.0 at $50,000 to 3.5 at $200,000. Again, that's the fixed insurance cost at work. By contrast, a higher property-tax state pulls every row down.

β€” According to the National Association of Realtors (September 2026), the median existing-home price hit $429,100 in August, up 1.6% from a year earlier. Under the same assumptions, buying that median home would take about $125,800 of gross salary.

So the typical home now sits just above the $125,000 row. For many single-income buyers, that's a real stretch on house affordability.

How do you calculate it yourself?

Working out how much house you can afford by hand takes five steps. Let's use a $90,000 salary, so you can check each one against the table.

  1. Find gross monthly income.
    First, divide $90,000 by 12 to get $7,500.
  2. Apply both caps.
    Next, 28% of $7,500 is $2,100, and 36% is $2,700.
  3. Subtract your debts.
    Then take other debts from the $2,700. With no debts, the $2,100 housing cap is lower, so it wins.
  4. Remove insurance.
    After that, subtract $200 for insurance. That leaves $1,900 for principal, interest, and property tax.
  5. Convert to a price.
    Finally, divide by the monthly cost per dollar of home price, shown below.

At 7.40% over 30 years, each $1,000 borrowed costs about $6.92 a month. With 20% down, you borrow $800 of every $1,000 in price. Add 1% annual tax, and each $1,000 of price costs about $6.37 a month.

Home price = (Housing cap βˆ’ Insurance) Γ· Monthly cost per $1 of price
           = ($2,100 βˆ’ $200) Γ· 0.0063724
           β‰ˆ $298,000

That price means a $238,530 loan and $59,632 down. Want proof? Enter $238,530 at 7.40% in our Mortgage Payment Calculator. You'll see about $1,652 a month in principal and interest. Then add $248 of tax and $200 of insurance, and you're back to $2,100.

How do your debts change your budget?

Here's a pattern most guides miss about how much house you can afford with debt. Under 28/36, your other debts don't touch your budget until they pass 8% of gross monthly income. That's the gap between 36% and 28%.

Once you cross that line, though, every extra dollar of debt comes straight out of your housing payment. At 7.40%, each extra $100 a month of debt removes about $15,700 of home price.

Annual salaryNo other debt$500/mo debt$1,000/mo debt
$50,000~$152,000~$126,000~$47,000
$60,000~$188,000~$173,000~$94,000
$75,000~$243,000~$243,000~$165,000
$100,000~$335,000~$335,000~$282,000
$125,000~$426,000~$426,000~$400,000
$150,000~$518,000~$518,000~$518,000

So a $500 car payment barely matters at $100,000. At $50,000, by contrast, it cuts about $26,000 from your price. In short, paying down debt before you buy helps most at lower incomes.

Lender maximum vs. comfortable budget: how big is the gap?

Lenders often approve buyers well past 28/36. So when you ask how much house can I afford, it's worth seeing both answers in dollars. The table uses the same assumptions and three rule sets from our Multi-Rule Home Affordability Calculator.

Mortgage Affordability Calculator

Annual salaryComfortable (28/36)Standard (31/43)Stretch (36/50)
$50,000~$152,000~$171,000~$204,000
$75,000~$243,000~$273,000~$322,000
$100,000~$335,000~$374,000~$439,000
$150,000~$518,000~$577,000~$675,000
$200,000~$701,000~$779,000~$910,000

As you can see, the stretch column buys about 30% to 35% more house. On a $100,000 salary, that's roughly $105,000 of extra price. It's also about $600 more each month.v

Real buyers feel this gap between mortgage affordability on paper and in practice. Take one r/Mortgages poster who asked, "Can we afford a $675k house on $10k take home per month?" The couple earned $198,000 combined, with $950 a month in student loans. Their lender's estimate was $4,200 a month, including taxes, insurance, and PMI.

On paper, that passes 28/36 easily. The housing ratio is about 25%, and total debt is about 31%. Yet $4,200 is 42% of their take-home pay. That's the gap between gross-income rules and real life.

For that reason, run a second check against take-home pay. Some planners use 25% of net pay as a comfort line. For this couple, that would mean about $2,500 a month. The truth probably sits somewhere between the two figures.

What does the 28/36 rule leave out?

The rule only sees debt payments. As a result, it can overstate how much house you can afford, because several real costs slip past it:

  • PMI if you put down less than 20%.
  • HOA dues, which count toward your housing ratio.
  • Closing costs, typically paid in cash at signing.
  • Maintenance and repairs, which never show up on a credit report.
  • Childcare, commuting, and savings goals.

Also, your rate matters more than any rule. A full point of rate can swing your price by roughly 10%. So get real quotes before you fall for a listing. Our PMI Calculator shows what a smaller down payment adds each month.

Calcavio's Verdict

The verdict

The 28/36 rule is still the best quick answer to "how much house can I afford?" as long as you check it against take-home pay.

Best for

First-time buyers setting a price range before talking to lenders.

Skip it if

You have large non-debt costs, like childcare or high commuting costs, that the rule can't see.

Pros and cons

Pros
  • Simple enough to do on a napkin
  • Matches how lenders actually measure risk
  • Leaves a cushion below lender maximums
Cons
  • Uses gross income, not take-home pay
  • Ignores savings, childcare, and maintenance

Standout

Your debts don't shrink a 28/36 budget until they pass 8% of gross income. After that, each $100 a month costs about $15,700 of house at 7.40%.

Calcavio Editorial Score

8/10
It's a clear, conservative guardrail. Still, its blind spot on take-home pay keeps it from a 9.

Frequently Asked Questions

Frequently asked questions

How much house can I afford on a $70,000 salary?+
On a $70,000 salary, the 28/36 rule caps housing at about $1,633 a month. At 7.40% with 20% down and no other debts, that supports roughly a $225,000 home. That figure assumes 1% property tax and $200 a month for insurance. In practice, your local tax rate changes this a lot. For example, a 2% tax rate would trim the price noticeably. Likewise, a $500 car payment would start to bite, since it's just above 8% of your monthly gross. In that case, the price slips to about $220,000. With $1,000 of monthly debt, it falls to roughly $141,000. So plug your state and debts into the calculator to see your own number.
Does the 28/36 rule use gross or net income?+
The 28/36 rule uses gross income, meaning your pay before taxes, retirement contributions, and health premiums. Lenders measure debt-to-income ratios the same way, so the rule mirrors how you'll actually be underwritten. However, gross income can flatter your budget. Taxes and payroll deductions often take 20% to 30% of pay. So a payment that looks like 28% of gross can be 35% to 40% of take-home. That's why it's smart to run both checks. First, test the payment against 28% of gross. Then compare it with your actual monthly deposits. If the payment feels tight against net pay, aim lower than the table suggests.
How much income do I need for a $500,000 house?+
To afford a $500,000 house under the 28/36 rule, you'd need about $145,000 of gross salary. That assumes 20% down ($100,000), a 7.40% 30-year rate, 1% property tax, $200 a month for insurance, and no other debts. The full payment would come to about $3,386 a month. That's $2,770 of principal and interest, $417 of tax, and $200 of insurance. With less than 20% down, you'd also pay PMI. In that case, you'd need more income to stay under 28%. Meanwhile, a lower rate would cut the income you need. For instance, at last year's 6.30% average, the same home would need noticeably less salary. Your lender's actual quote is what counts.
Can I get a mortgage with a DTI above 36%?+
Yes, many borrowers get approved with a debt-to-income ratio above 36%. Fannie Mae allows up to 45% on manually underwritten loans with strong credit and reserves, and up to 50% through Desktop Underwriter. FHA's standard limits are 31% and 43%. In addition, VA loans use a 41% guideline backed by a residual-income test. FHA can also go higher with compensating factors, like cash reserves. Still, approval and comfort are different things. A 45% ratio leaves less room for repairs, job changes, or a new baby. So treat the lender's number as a ceiling, not a target. Ask what your ratio would be at the payment you'd actually choose, not just the maximum.
Is the 28/36 rule still realistic in 2026?+
The 28/36 rule is still a sound comfort test in 2026, but higher rates make it harder to pass. At Freddie Mac's 7.40% average, a $100,000 salary supports about $335,000 of house. At last year's 6.30%, it supported roughly $369,000. In other words, the same income lost about $34,000 of buying power in a year. Meanwhile, NAR's August median price of $429,100 would take about $125,800 of salary under the rule. So many buyers now face a choice. They can buy below the median, wait and save, or stretch past 28%. Our breakdown of mortgage buying power at 7.4% shows the full rate math.
Does a bigger down payment let me afford more house?+
Yes, a bigger down payment usually raises the price you can afford. More cash means a smaller loan, a lower payment, and often no PMI. Under the 28% cap, your monthly budget is fixed, so a cheaper loan stretches further. For example, take a $100,000 salary at 7.40%. With 20% down, the rule supports about $335,000. With 10% down and PMI at 0.5% a year, it supports only about $287,000. That's because PMI and the larger loan both use up the same $2,333. Of course, saving the extra 10% takes time. Our Down Payment Savings Calculator shows how long it takes to save the difference.

Bottom line

So, how much house can I afford on my salary? Under the 28/36 rule, most buyers land at about 3 to 3.5 times their salary at today's 7.40% average. Lenders may approve far more.
