How Much House Can You Afford? A Realistic Calculator-Based Guide

The Honest Answer to "How Much House Can I Afford on My Salary?"

Most people get this question backward. They go to a bank, find out the maximum they can borrow, and then start shopping at that ceiling. That's how you end up house-rich and cash-poor — "house poor" is the term, and it's more common than you'd think.

The better question isn't what a lender will approve. It's what monthly payment you can comfortably carry while still funding your retirement, handling emergencies, and actually enjoying your life. Those numbers are almost always different, and the gap between them is where financial stress lives.

This guide will walk you through how to figure out your real number — not the bank's number — using income-based rules, a table you can reference in 30 seconds, and concrete examples at various salary levels. By the end, you'll have a realistic target range and know exactly what to do with it.

The Two Rules Most Financial Advisors Use (and Their Limits)

There are two widely-used benchmarks for home affordability. Both are useful. Neither is the whole story.

The 28/36 Rule

This is the gold standard. It says your housing costs — mortgage principal and interest, property taxes, homeowner's insurance, and HOA fees if applicable — should not exceed 28% of your gross monthly income. Your total debt load (housing plus car payments, student loans, credit cards, and any other recurring debt) should stay under 36% of gross monthly income.

So if you earn $80,000 a year, your gross monthly income is about $6,667. The 28% rule puts your max housing payment at roughly $1,867. The 36% rule caps your total debt at $2,400 — meaning if you're already paying $400/month on a car loan and $300 on student loans, you've got about $1,700 left for housing.

Lenders often use a slightly looser version of this rule — they may approve loans where housing costs reach 31% and total debt hits 43%. That's the FHA ceiling for most borrowers. But just because you can be approved doesn't mean you should stretch that far.

The 2.5x to 3x Income Rule

This is the quick-math version. Multiply your gross annual income by 2.5 to 3, and that's roughly the home price range where you're probably safe. At $80,000, that's $200,000 to $240,000. At $120,000, you're looking at $300,000 to $360,000.

In today's market, this rule feels brutal — especially in expensive metros. But it's not arbitrary. It reflects what monthly payments look like relative to take-home pay at different interest rate environments, and it builds in margin for life's inevitable surprises.

The reality is that in high-cost cities like San Francisco, Seattle, or New York, even high earners often can't satisfy the 3x rule without a significant down payment. That's not a failure of the rule — it's information about whether that market makes financial sense for you right now.

Why Both Rules Have Limits

These rules use gross income, but you don't spend your gross income — you spend what lands in your checking account after taxes, health insurance, 401(k) contributions, and everything else that comes out before you see a dollar. Depending on your tax bracket and benefit elections, that take-home number can be 25–35% lower than your gross.

A more conservative approach: run the 28% calculation on your net monthly income instead. This is a tighter standard, but it's also a more honest one.

Affordability by Income Level: A Quick Reference Table

The table below gives you a realistic ballpark based on current market conditions. It assumes a 20% down payment, a 30-year fixed mortgage at 7.0% interest, and that property taxes plus insurance add roughly 1.5% of home value per year. Adjust from there based on your actual down payment and local tax rates.

Annual Salary	Max Housing Payment (28%)	Estimated Home Price Range	Notes
$50,000	$1,167/mo	$130,000 – $165,000	Tight in most markets; rural/Midwest may work
$65,000	$1,517/mo	$170,000 – $215,000	Solid range in secondary markets
$80,000	$1,867/mo	$210,000 – $265,000	Near U.S. median; workable in many metros
$100,000	$2,333/mo	$265,000 – $330,000	Comfortable in most mid-size cities
$125,000	$2,917/mo	$330,000 – $415,000	Entry-level in high-cost metros
$150,000	$3,500/mo	$395,000 – $495,000	Solid buying power nationally
$200,000	$4,667/mo	$525,000 – $660,000	Covers most markets; stretched in coastal cities
$250,000+	$5,833/mo+	$660,000 – $830,000+	Jumbo territory; lender criteria shifts

*Estimates based on 7.0% 30-year fixed rate, 20% down payment, and ~1.5% annual property tax + insurance. Use the home affordability calculator for your specific numbers.

A few things to notice in this table. First, the jump from $50K to $100K in salary doesn't translate to a proportional jump in buying power — taxes eat more at higher incomes, and each mortgage dollar costs the same regardless of what you earn. Second, at 7% interest rates, even a $100,000 salary only stretches to about $300K in home price comfortably. That's a real constraint in cities where median home prices are $500K or more.

What Your Salary Actually Gets You: Real-World Examples

The table above is useful for quick reference, but let's work through a few realistic scenarios so the math becomes concrete.

Example 1: The $75,000 Solo Buyer

Jamie earns $75,000 gross. Monthly gross is $6,250. The 28% rule puts her max housing payment at $1,750/month. She has $250/month in student loan payments, so her 36% debt ceiling ($2,250 total) leaves her with $2,000 for housing — but she stays conservative and targets $1,700 to keep some breathing room.

At 7% on a 30-year fixed with 20% down, a $1,700 payment (before taxes and insurance) supports a loan of roughly $255,000. Add the 20% down, and she's looking at a $315,000 purchase price — but only if property taxes and insurance stay modest. In a state with higher property taxes, that number could drop to $280,000.

Her practical budget: $270,000 to $310,000, assuming she has the 20% down payment saved (about $54,000 to $62,000 plus closing costs).

Example 2: The Dual-Income Household at $140,000 Combined

Alex and Jordan together earn $140,000 — Alex at $85,000, Jordan at $55,000. Combined gross monthly is $11,667. The 28% ceiling puts their max housing payment at $3,267.

They carry $600/month in combined auto loans and no other debt. Their total debt ceiling at 36% is $4,200, leaving $3,600 for housing — but again, they target below the maximum and aim for $2,900 to keep retirement contributions and savings intact.

At $2,900/month all-in (PITI — principal, interest, taxes, insurance), they can comfortably shop in the $390,000 to $430,000 range with a 20% down payment.

One important wrinkle: if Jordan's income is variable (commission, contract, or part-time), a smart approach is to qualify and budget based only on Alex's $85,000. Use Jordan's income as a buffer, not a requirement. This is how you avoid financial fragility when one income source changes.

Example 3: The $110,000 Earner With Significant Existing Debt

Taylor earns $110,000. Monthly gross is $9,167. The 28% ceiling is $2,567. But Taylor carries $650/month in student loans and $400/month in car payments — that's already $1,050 in non-housing debt before a mortgage.

The 36% total debt ceiling is $3,300. Subtract $1,050 in existing debt, and Taylor has $2,250 left for housing — well below the raw 28% number. This is exactly why you can't skip the full debt-to-income analysis. Taylor's high income is meaningfully constrained by existing obligations.

Taylor's realistic home budget: closer to $290,000 to $320,000, not the $370,000+ that the salary alone might suggest. Running a debt-to-income calculation makes this clear in minutes.

The Hidden Costs That Most First-Time Buyers Miss

Even buyers who do the mortgage math correctly often underestimate the full cost of homeownership. This isn't meant to scare you off — it's just the honest accounting that makes the difference between a comfortable purchase and a stressful one.

Closing Costs

Expect to pay 2–5% of the purchase price in closing costs: loan origination fees, title insurance, appraisal, attorney fees (in some states), prepaid taxes and insurance, and more. On a $350,000 home, that's $7,000 to $17,500 in cash — in addition to your down payment. These costs don't disappear if you roll them into the loan; they just get added to what you're paying interest on for 30 years.

The Maintenance Reserve

A commonly cited rule is to budget 1% of your home's value per year for maintenance and repairs. On a $350,000 home, that's $3,500 annually, or roughly $290/month. Some years you'll spend nothing. Other years your HVAC dies, your roof needs work, or you discover the deck has dry rot. The money needs to be there either way.

Many first-time buyers skip this reserve entirely, which means a $6,000 furnace replacement becomes a credit card emergency. If you're budgeting to the absolute edge of what you can afford, this is the line item that will hurt you.

Property Taxes and Insurance

These vary enormously by location. New Jersey homeowners pay some of the highest effective property tax rates in the country — often 2% or more of assessed value annually. Texas and Illinois aren't far behind. States like Hawaii and Alabama are considerably lower.

If you're shopping in a high-tax state, this can add hundreds of dollars per month to your effective housing cost. A $400,000 home in New Jersey might carry $800–$1,000/month in property taxes alone. The Consumer Financial Protection Bureau's homeownership resources include useful tools for understanding regional cost differences.

HOA Fees

If you're buying in a planned community, condo, or anywhere with a homeowners association, monthly HOA fees can range from $100 to $1,000 or more. These count toward your housing costs for DTI purposes and they tend to increase over time. Review the HOA's financials before you buy — an underfunded reserve account is a red flag that special assessments may be coming.

Utilities

Moving from a 900-square-foot apartment to a 2,400-square-foot house can easily double or triple your utility bills. Gas, electric, water, trash — all of these scale with the size and age of the property. Older homes with single-pane windows or aging insulation can be particularly expensive to heat and cool.

How Down Payment Size Changes Everything

The table above assumes 20% down, and there are good reasons for that benchmark — but it's not the only path to homeownership.

A 20% down payment eliminates Private Mortgage Insurance (PMI), which typically costs 0.5–1.5% of the loan amount per year. On a $300,000 loan, that's $1,500 to $4,500 annually, or $125 to $375 added to your monthly payment. PMI is not permanent — it typically falls off once you reach 20% equity — but it meaningfully affects affordability in the early years.

If you put down less than 20%, factor PMI into your monthly payment calculation when figuring out what you can afford. The good news is that FHA loans allow as little as 3.5% down (with mortgage insurance), and conventional loans can go as low as 3% through certain programs. VA loans and USDA loans have zero down payment options for qualifying buyers.

The tradeoff: a smaller down payment means a larger loan balance, higher monthly payments, more interest paid over the life of the loan, and PMI costs until you reach the 20% equity threshold. Use a mortgage payment calculator to see exactly how different down payment amounts change your monthly obligation and total cost.

The Opportunity Cost Question

There's a real argument against always maximizing your down payment: if you drain every dollar of savings to get to 20% down, you have no emergency fund, no cushion for repairs, and no margin for anything unexpected in the first year of ownership. That's a precarious position.

A reasonable middle ground for many buyers: put down enough to avoid PMI or to get to a comfortable loan-to-value ratio, but not so much that you're starting homeownership broke. Keeping 3–6 months of expenses in a liquid emergency fund after closing is worth more than a slightly lower loan balance.

The Rent vs. Buy Decision Is Part of the Equation

In some markets and life situations, buying a home right now is simply not the right financial move — regardless of what you can technically afford. Renting isn't throwing money away. It's paying for housing flexibility, no maintenance costs, and often a lower all-in monthly cost than ownership in high-price markets.

The break-even timeline on a home purchase — the point at which buying becomes cheaper than renting the equivalent space — can range from 3 years to over 10 years depending on price-to-rent ratios, interest rates, and local appreciation assumptions. If you're likely to move within 5 years, buying in most markets probably doesn't pencil out financially, even if you can afford the payments.

Before you commit, it's worth running a full rent vs. buy comparison with your actual numbers. The answer might surprise you.

Getting Your Finances in Shape Before You Apply

If your number right now isn't where you want it to be, that's actionable information — not a dead end. Here's what actually moves the needle.

Credit Score

Your credit score affects both whether you qualify and what interest rate you'll receive. The difference between a 680 score and a 760 score on a $300,000 mortgage can be 0.5–0.75 percentage points in rate — which translates to roughly $85–$130 more per month and tens of thousands of dollars over the loan's life.

Pull your free reports at AnnualCreditReport.com, check for errors (they're more common than you'd think), pay down revolving balances to below 30% utilization, and avoid opening new credit accounts in the months before applying.

Existing Debt

Paying off high-interest debt before buying a home does two things: it reduces your DTI (which expands what you can borrow and reduces rate risk) and it frees up cash flow. If you have consumer debt at 20%+ interest, there's a strong argument for eliminating that before saving for a down payment. The math almost always works out in your favor.

Income Documentation

Lenders want to see consistent, documentable income. If you're self-employed, a freelancer, or have recently changed jobs, the underwriting process requires more documentation and may require 2 years of tax returns to average your income. Variable income (bonuses, commissions, overtime) is typically averaged over 24 months, not taken at face value.

The Financial Order of Operations

Saving for a home makes sense at a specific point in your financial life — not necessarily right now. If you're still building an emergency fund, haven't captured your employer 401(k) match, or are carrying high-interest debt, those items typically take priority. Understanding the financial order of operations can help you sequence your decisions so that homeownership, when you get there, is genuinely a foundation rather than a financial strain.

Get Your Actual Number with a Calculator

The rules and examples in this guide give you a reliable framework — but your number depends on your specific income, debts, down payment, target location, and current interest rates. Rates move, tax assessments vary, and insurance costs differ dramatically by zip code and property type.

The most accurate thing you can do right now is run your real numbers through the PocketWise home affordability calculator. It accounts for your income, existing debts, down payment, and local estimates to give you a personalized target range — not just a salary multiple.

A few inputs to have ready:

Your gross annual income (and your partner's, if applicable)
Monthly minimum payments on all existing debts (student loans, car loans, credit cards)
How much you have saved for a down payment
The state or metro you're shopping in (for property tax estimates)
Current mortgage interest rates (check a rate aggregator or your lender)

Five minutes of honest input gives you a number you can actually shop around. That's more useful than any rule of thumb, because it's yours.
