Buying a home is the biggest financial decision most people ever make — and the question "how much house can I afford?" carries far more weight than it first appears. Your salary is only part of the answer. Interest rates, property taxes, homeowners insurance, existing debts, down payment size, and the gap between what a lender will approve you for and what you can actually live with all shape the real number. This guide walks through the exact math lenders use in 2026, shows real affordability figures by income level, and explains the difference between qualifying for a mortgage and being comfortable with one.
How Much House Can I Afford?
A safe estimate is that you can afford a home priced at roughly 3 to 4 times your gross annual income, provided your total monthly housing costs stay under 28% of gross monthly income and your total debts stay under 36%. At today's average 30-year rate of about 6.58% with 20% down, a household earning $100,000 can comfortably afford a home priced around $335,000 to $380,000. Recalculate your number whenever rates move by more than 0.25%, and always leave a 10–15% cushion below whatever a lender approves.
Why "You Can Afford X" Answers Are Almost Always Wrong
Two households earning the same $120,000 per year can have wildly different home-buying power. One has $600 in car and student loan payments; the other is debt-free. One lives in a state with 2.2% property tax; the other in a state with 0.7%. One has 20% saved for a down payment; the other has 5%. All four of these differences move the affordable home price by tens of thousands of dollars — and none of them are captured by a generic "3× your salary" rule.
The starting point for any sensible home affordability calculation is your personal debt-to-income ratio, not a rule of thumb. Once you know it, everything else — your maximum monthly payment, your target home price, your down payment goal — falls into place as arithmetic.
The 28/36 Rule: The Foundation of Home Affordability
Every mortgage affordability calculation starts here. The 28/36 rule is the benchmark lenders have used for decades, and it remains the single most important formula for figuring out how much house you can afford in 2026.
| Ratio | What It Covers | Cap | Why It Matters |
|---|---|---|---|
| Front-End DTI | Monthly PITI only (principal, interest, taxes, insurance) | 28% | Protects you from housing eating your paycheck |
| Back-End DTI | PITI + all other monthly debts (car, student, credit card, personal loans) | 36% | Ensures total debt load stays manageable |
Worked Example
Household earning $8,000/month gross, with $600 in other debts
28% front-end cap: $8,000 × 0.28 = $2,240 max PITI
36% back-end cap: $8,000 × 0.36 = $2,880 total debts
After subtracting $600 in other debts: $2,880 − $600 = $2,280
Max monthly housing payment: $2,240 (lower of the two)
Whichever ratio produces the smaller number becomes your ceiling. If you have no other debts, the 28% rule almost always sets the cap.
Today's Mortgage Rates and Why They Change What You Can Afford
As of late July 2026, the average 30-year fixed mortgage rate is hovering around 6.58%, with the 15-year fixed near 5.96%. Rates have sat in the 6% range throughout 2026, and Fannie Mae's latest forecast projects they'll stay near 6.4% through year-end.
A single percentage point on your mortgage rate changes what you can afford by tens of thousands of dollars. Here is what the same $500,000 loan looks like at three different rates:
| Interest Rate | Monthly P&I | Total Interest (30 yrs) | Payment vs. 5% |
|---|---|---|---|
| 5.00% | $2,684 | $466,278 | Baseline |
| 6.58% | $3,185 | $646,530 | +$501/mo |
| 7.50% | $3,496 | $758,772 | +$812/mo |
That $501 monthly gap between 5% and 6.58% is real money. At a 28% housing ratio, you need to earn about $21,500 more per year to afford the same house at today's rates than you would have at 5%. This is exactly why running the numbers through a home mortgage calculator with current rates matters — old rules of thumb from the 2010s no longer apply cleanly.
What Your Monthly Mortgage Payment Actually Includes (PITI)
When people say "mortgage payment," they usually mean just principal and interest. But your real monthly obligation is bigger. Lenders calculate affordability using PITI:
THE FOUR COMPONENTS OF PITI
P — Principal: portion that reduces the loan balance
I — Interest: cost of borrowing, based on the remaining balance
T — Taxes: property taxes, typically 1–2.5% of home value per year
I — Insurance: homeowners insurance + PMI (if down payment under 20%)
Skip PITI and your affordability estimate will be off by hundreds of dollars a month. On a $400,000 home in a state like New Jersey with a 2.2% property tax rate, you're looking at roughly $733 per month in property taxes alone. In Tennessee, at 0.7%, the same home costs about $233 a month in taxes — a $500 gap that translates to about $85,000 in affordable home price at today's rates.
How Much House Can You Afford By Income? Real 2026 Numbers
This is the table most homebuyers actually want to see. All numbers assume a 30-year fixed mortgage at 6.58%, 20% down, 1.25% property tax, 0.35% insurance, and no existing debts. Numbers get smaller if you have car loans, student loans, or a smaller down payment.
| Annual Income | Max PITI (28%) | Comfortable Home Price | Stretched Home Price |
|---|---|---|---|
| $50,000 | $1,167 | $165,000 | $210,000 |
| $75,000 | $1,750 | $250,000 | $315,000 |
| $100,000 | $2,333 | $335,000 | $420,000 |
| $125,000 | $2,917 | $420,000 | $525,000 |
| $150,000 | $3,500 | $500,000 | $630,000 |
| $200,000 | $4,667 | $670,000 | $835,000 |
| $250,000 | $5,833 | $835,000 | $1,050,000 |

The "comfortable" column applies the 28% front-end rule. The "stretched" column pushes to 35%, which most lenders will approve for buyers with solid credit and no other debt. Just because you can borrow that much doesn't mean you should — stretched numbers leave little room for savings, emergencies, or lifestyle spending.
Down Payment: The Lever That Changes Everything
Your down payment does two things: it lowers the amount you need to borrow, and it can eliminate Private Mortgage Insurance (PMI). PMI is required on conventional loans when you put down less than 20%, typically costing between 0.3% and 1.5% of your loan amount per year.
| Loan Type | Min. Down | PMI Required? | Best For |
|---|---|---|---|
| Conventional | 3–5% | Yes, below 20% | Credit 680+, plans to reach 20% equity |
| FHA | 3.5% | Yes, life of loan | Credit 580–680, higher DTI |
| VA | 0% | No PMI | Veterans and active-duty military |
| USDA | 0% | Yes (guarantee fee) | Rural and eligible suburban areas |
| Conventional 20% | 20% | No PMI | Buyers with substantial savings |

Loan Programs and Their DTI Limits in 2026
Not all mortgages have the same debt-to-income limits. If your DTI is on the higher side, the loan program you choose can be the difference between approval and denial.
| Loan Type | Standard DTI Cap | Max DTI (with compensating factors) |
|---|---|---|
| Conventional (Fannie/Freddie) | 43% | Up to 50% |
| FHA | 43% | Up to 57% |
| VA | 41% | Up to 60% |
| USDA | 41% | Up to 46% |
| Jumbo | 43% | Up to 45% |
"Compensating factors" usually means a credit score of 720 or higher, substantial cash reserves (typically 3 to 6 months of PITI in the bank), a large down payment, or a very stable employment history. Without them, expect lenders to hold you closer to the standard cap.
One more thing to know: 2026's conforming loan limit — the maximum for a standard conventional loan — is $832,750 in most U.S. areas. Anything above that is a jumbo loan, which comes with slightly higher rates and stricter requirements.
How to Actually Use a Mortgage Affordability Calculator
A mortgage calculator turns theory into one clean number — but only if you feed it accurate inputs. Follow this workflow:
Run this in our home mortgage calculator and cross-check the monthly payment with our loan calculator to see how principal and interest change over the life of the loan. If you're a freelancer or self-employed, remember lenders use your net income after business expenses — our freelancer tax calculator helps you estimate the number they'll actually see on your tax returns.
Renting vs. Buying: When Does Buying Actually Make Sense?
Buying isn't always the right move. At 6.58% mortgage rates, the classic "buying is always better than renting" wisdom often falls apart in the first three to five years. Break-even on transaction costs — closing costs plus selling costs down the road — typically takes 5 to 7 years at today's rates.
| Buying Makes Sense When... | Renting Makes Sense When... |
|---|---|
| You'll stay in the home for at least 5 years | You may move within 3 years for career or family |
| PITI is within 15% of local rent for a comparable home | Local rent is significantly cheaper than owning |
| You have 3–6 months of expenses saved after the down payment | You'd be stretching to hit the down payment |
| Your income is stable and career direction is settled | Your income is variable or you value flexibility |
| You want customization and long-term stability | You'd rather invest the difference elsewhere |
Our rent calculator helps you figure out what you can afford in rent so you can make a fair side-by-side comparison against a mortgage payment.
How to Increase How Much House You Can Afford
If the number from your affordability calculation is smaller than you hoped, you have real levers to pull. In order of impact:
- Pay down high-payment debts. A $500 car payment paid off equals roughly $80,000 more in home price at today's rates. The biggest lever most buyers ignore.
- Increase your down payment. Every extra $10,000 down reduces your monthly payment by about $65 at 6.58%, or lets you buy about $12,000 more in home.
- Improve your credit score. Going from 680 to 760 can cut your rate by 0.25% to 0.5%, saving hundreds a month or letting you afford $30,000 to $60,000 more home.
- Buy in a lower-tax jurisdiction. Moving from a 2.2% property tax state to a 0.7% state can add $150,000+ to your affordable home price on the same income.
- Consider a longer-term loan carefully. These lower your monthly payment but cost far more over time. Only use them if you have a clear payoff plan.
- Add a co-borrower. A spouse, partner, or family member with additional income increases the amount you can qualify for.
One thing not to do: don't stretch to the absolute lender maximum. Every experienced homeowner will tell you the same thing — leaving a cushion is what makes homeownership enjoyable rather than stressful.
