Home Affordability Calculator 2026: How Much House Can You Afford?

On an $80,000 salary with no debt, you can afford a home up to $340,000–$360,000. Add a $500/month car payment and that drops to $250,000–$270,000 — a $90,000 reduction in buying power from one monthly payment. Most first-time buyers discover this only after they're already in love with a house they can't qualify for. This guide shows you the exact numbers before that happens.

How Much House Can You Afford — By Salary

Assuming 20% down payment, no existing debt, 6.8% interest rate, 30-year mortgage, $3,600/year property tax and $1,800/year insurance. This is the clean baseline:

$50,000$4,167$1,167$155,000$1,010/mo
$60,000$5,000$1,400$200,000$1,300/mo

$150,000$12,500$3,500$585,000$3,806/mo

Assumes 20% down, no debt, 6.8% rate, 30yr term. Includes estimated tax and insurance.

💡 The Real Rule of Thumb

A simple quick estimate: you can typically afford a home worth 3–4x your annual gross salary. On $80K that's $240K–$320K. On $120K that's $360K–$480K. This rough guide works well for people with little debt and standard down payments — but the 28/36 calculator gives you the precise number.

How Debt Destroys Your Home Buying Power

🏠 How Monthly Debt Kills Your Home Buying Power — 2026

Each $200/month in existing debt (car, student loan, credit card) erases ~$29,000 in home buying power.

This is the part most buyers discover too late. Every dollar of monthly debt payment reduces your maximum home price by roughly $15,000–$18,000. Here's exactly what common debt loads do to a $100,000 salary buyer:

$100,000 Salary — Impact of Existing Debt on Max Home Price
No existing debt$370,000 max home
$300/mo student loan$315,000 max home (-$55,000)
$500/mo car payment$280,000 max home (-$90,000)
$700/mo car + student loan$245,000 max home (-$125,000)
$1,000/mo total debt$190,000 max home (-$180,000)

A $700/month combined debt load costs this buyer $125,000 in home buying power. That's often the difference between a starter home in a good neighbourhood and a great home in the same neighbourhood. Paying off debts before buying is almost always worth it.

The 28/36 Rule — What Lenders Actually Check

📐 The 28/36 Rule: What Lenders Check on Every Mortgage Application

Front-end DTI (28%) covers just housing costs. Back-end DTI (36%) includes all monthly debt payments — the stricter limit lenders use.

Every conventional mortgage lender uses two DTI ratios to qualify you. Understanding both is essential:

Front-End DTI — The 28% Rule

Your total housing costs — Principal + Interest + Property Tax + Insurance + PMI + HOA — cannot exceed 28% of gross monthly income. On $8,333/month gross ($100K salary), the maximum housing payment is $2,333/month. This is the number the bank calculates first.

Back-End DTI — The 36% Rule

All monthly debt payments combined — housing PLUS car loans, student loans, credit cards, personal loans — cannot exceed 36% of gross income. On the same $100K salary, that's $3,000/month maximum total debt. If you already have $700/month in other debts, you only have $2,300/month left for housing — which cuts your max home price significantly.

⚠️ The DTI Limit That Actually Gets Used

While 36% is the traditional guideline, many lenders today approve up to 43% back-end DTI for conventional loans and up to 50% for FHA. However, approval at 43–50% DTI typically means higher interest rates, stricter income verification, and less room for error. Staying under 36% gives you the best rates and the easiest approval process.

PMI — The Hidden Cost That Changes Everything

If your down payment is below 20%, you pay Private Mortgage Insurance every month on top of your mortgage. PMI protects the lender — not you — and typically costs 0.5–1.5% of the loan amount annually. On a $300,000 loan that's $125–$375/month you're paying for zero benefit to yourself.

Loan AmountPMI RateMonthly PMIAnnual PMITotal PMI (7 yrs to 20%)
$200,0000.5%$83/mo$1,000/yr$7,000
$300,0000.6%$150/mo$1,800/yr$12,600
$400,0000.7%$233/mo$2,800/yr$19,600
$500,0000.8%$333/mo$4,000/yr$28,000

On a $400,000 loan with 10% down, PMI costs $233/month until you reach 20% equity — typically 7–9 years. That's $19,600 paid to the lender's insurance company before PMI is cancelled. This is why the 20% down target exists — it's not arbitrary, it's a hard cash saving.

When Can I Remove PMI?

PMI isn't permanent — federal law gives you two guaranteed paths to drop it, plus an option to request removal earlier than the automatic schedule. These rules come from the Homeowners Protection Act (HPA) and apply to most conventional loans (they don't apply to FHA loans, which use MIP with different rules).

💡 Worked Example — $400,000 Home, 10% Down

Home price: $400,000. Down payment: 10% ($40,000). Starting loan balance: $360,000 (90% LTV).

80% LTV (request removal): reached once the balance falls to $320,000 — that's $40,000 of principal paydown (plus any appreciation) beyond the down payment. On a 30-year loan this typically happens around year 4–5 of amortization, sooner if you make extra payments or the home's value has risen and an appraisal confirms it.

78% LTV (automatic termination): reached once the balance falls to $312,000, based purely on the original schedule — this happens automatically even if you never ask, typically a year or so after the 80% mark.

At roughly $233/month in PMI (0.7% annual rate on this loan size), reaching 80% LTV two years earlier than the automatic 78% cutoff — by paying extra toward principal or requesting an appraisal after the market rises — can save well over $1,000 in unnecessary PMI premiums.

To request early removal, contact your loan servicer in writing, ask what's required (often a written request, good payment history, and no other liens on the home), and be prepared to pay for an appraisal if your case relies on appreciation rather than scheduled paydown. If the servicer confirms you're at or below 80% LTV and you meet the payment history requirements, they're required to remove PMI.

Should You Buy Now or Save for 20% Down?

This is the most common dilemma for first-time buyers in 2026. Here's how to think through it:

Frequently Asked Questions

How much house can I afford on $80,000 a year?+
On $80,000/year with no debt and 20% down at 6.8% interest: maximum home price is approximately $285,000–$300,000. Monthly payment including taxes and insurance runs around $1,850–$2,000. If you have a $500/month car payment, your max drops to roughly $195,000–$215,000. The 28% rule says your maximum housing payment is $1,867/month on that salary — everything flows from that number.
Does the 28/36 rule include property tax and insurance?+
Yes — the front-end 28% includes PITI: Principal, Interest, Taxes, and Insurance. This means your property tax and homeowner's insurance are counted as part of your housing cost against the 28% limit. HOA fees are also typically included. Many buyers calculate based on principal and interest alone and are surprised when taxes and insurance push them over the DTI limit.
Can I get approved with a higher DTI than 36%?+
Yes — many lenders approve up to 43% back-end DTI for conventional loans and up to 50% for FHA loans. However, exceeding 36% typically means higher interest rates, stricter income documentation requirements, and often requires compensating factors like excellent credit (740+), large cash reserves, or significant assets. Staying under 36% gives you the most loan options at the best rates.
Should I pay off my car before buying a house?+
If you can pay off your car within 12 months, it almost always makes sense to wait and pay it off first. A $450/month car payment reduces your max home price by $80,000–$90,000 — paying off the car and buying a more expensive home in the same market often means lower total monthly payments because the mortgage rate is far lower than any car loan rate. Run the numbers either way before deciding.
What is the minimum credit score to buy a house in 2026?+
Conventional loans: 620 minimum, though 740+ gets the best rates. FHA loans: 580 with 3.5% down, or 500–579 with 10% down. VA loans: no official minimum but most VA lenders want 620+. USDA loans: 640 minimum typically. The credit score difference between 620 and 760 on a $300,000 mortgage can be $80–$150/month in interest — worth improving your score if you're below 700.
