You can estimate how much of a house loan you can afford by looking at your income, debts, and how much you have for a down payment, then applying a few common rules lenders use to size mortgages.

Quick Scoop

  • A common rule is that your total housing costs should be around 28–30% of your gross (before‑tax) monthly income.
  • Your total monthly debt payments (housing + all other loans/credit cards) generally should not exceed about 36–43% of your gross income, depending on loan type and lender.
  • Online affordability calculators from big lenders and financial sites can quickly show a realistic price range once you plug in your numbers.

Below is a practical way to think about it, plus a mini storytelling example so it feels more real.

Step 1: Know Your Key Numbers

Write down three basics :

  • Monthly gross income (you + partner, if buying together).
  • Monthly debts: car payments, student loans, credit cards, personal loans, etc.
  • Available cash: down payment + closing costs buffer.

Lenders also look at:

  • Credit score and history (affects interest rate and how much you qualify for).
  • Employment stability and documented income.
  • Property taxes, insurance, and sometimes HOA fees.

These extra costs mean your “mortgage payment” is not just principal and interest, but also taxes and insurance rolled in.

Step 2: Use the 28/36 and 36/43 Ideas

The 28/36 rule (common guideline)

  • Max 28% of gross income on housing (mortgage + property tax + insurance).
  • Max 36% of gross income on all debts combined.

The 36/43 ranges (what many lenders actually allow)

  • Some lenders (especially conventional) are comfortable if your housing costs are in the low‑30% range as long as your total debt stays under roughly 43%.
  • FHA and VA loans may allow total debt ratios in the low‑40% range, depending on the rest of your profile.

Think of this as a spectrum: more conservative around 28/36, more flexible up to roughly 36/43.

Step 3: Turn Ratios Into a Monthly Payment

Here’s how to roughly convert your income into an affordable payment target:

  1. Take your gross monthly income.
  2. Multiply by 0.28 to get a conservative housing budget.
  3. Multiply by about 0.33–0.36 to see a more aggressive but often lender‑accepted level, then check your other debts so that total stays under about 40–43%.

Example:

If you earn 5,000 per month before tax, 28% is 1,400 and 33% is 1,650.
That suggests a safe housing payment around 1,400 and a “stretch but still common” payment up to about 1,650, as long as other debts are modest.

For FHA, an example from one major site: a 3,000 monthly income could support a total debt around 1,290 and housing around 900 (roughly 31% on housing, 43% on total debt).

Step 4: Translate Payment Into Loan Size

How much loan those payments support depends on:

  • Interest rate (huge impact).
  • Loan term (30‑year vs 20‑year vs 15‑year).
  • Property tax rates in your area.
  • Homeowners insurance cost.

Most public calculators let you:

  • Enter your income, debts, and down payment.
  • Choose an interest rate and term (e.g., 30 years).
  • Estimate taxes and insurance.
  • See an approximate maximum home price and mortgage amount.

Some calculators provide sample ranges by salary; for example, one popular tool shows that someone earning around 100,000 per year with a modest down payment might afford a home in the upper‑200k range under typical assumptions, while higher incomes scale that number into the high six figures or more.

Step 5: Don’t Forget the Down Payment

Your down payment shapes:

  • How much you need to borrow.
  • Whether you’ll pay mortgage insurance.
  • How lenders view your risk level.

Common patterns:

  • 3–5% down: possible with some conventional and first‑time buyer programs, but usually includes mortgage insurance.
  • Around 10–20% down: reduces monthly payment and may remove mortgage insurance, increasing how “affordable” a house feels at the same income.
  • Bigger down payment can sometimes offset slightly higher debt ratios.

Some 2026‑focused guides, especially in markets like Australia, highlight how rising prices have made deposit size a key constraint, not just income.

Step 6: Lender Calculators vs Real Life

Big players like Zillow, Bankrate, Chase, Wells Fargo, LendingTree, and others offer interactive “how much house can I afford?” tools.

They typically:

  • Ask for your income, debts, down payment, and location (for tax estimates).
  • Use standard debt‑to‑income limits and current rate assumptions.
  • Spit out a home price range and monthly payment estimate.

Regulators like the FDIC also publish consumer‑friendly guides that walk through these calculations step by step and explain how stretching too far can increase risk if your income drops or rates rise.

Real‑world twist: many people in 2024–2026 affordability discussions say the calculator “maximum” feels too high once they consider childcare, travel, lifestyle, and savings goals, so they choose to stay below the suggested top number.

Mini Story: A Realistic Scenario

Imagine Alex:

  • Gross monthly income: 7,000.
  • Debts: 250 car, 150 student loan, 100 credit cards → 500 total.
  • Wants a 30‑year fixed mortgage.

Using 28%:

  • Housing target: 7,000 × 0.28 = 1,960 per month.

Total debt check:

  • 1,960 housing + 500 other = 2,460.
  • 2,460 á 7,000 ≈ 35% total DTI, under a 36–43% range many lenders use.

With current rates and typical taxes/insurance, calculators from big sites might show that a payment around 1,900–2,000 could support a home price in the low‑ to mid‑300k range if Alex has a standard down payment, though the exact figure depends heavily on the interest rate and local taxes.

2025–2026 Context: Why This Matters

From 2024 into early 2026, a lot of online discussion has focused on:

  • Higher mortgage rates compared with the ultra‑low era, which cut affordability even when incomes rise.
  • Strong house prices in many regions, meaning the same income now buys less home than a few years ago.
  • More buyers using affordability calculators early, before house‑hunting, so they don’t waste time on homes outside their realistic range.

Many forum threads and consumer articles emphasize planning for:

  • Emergency savings after closing.
  • Maintenance costs (roof, appliances, repairs).
  • Life changes (kids, job shifts, healthcare).

In other words, “How much will a bank lend me?” and “How much can I comfortably afford?” are not always the same number.

Simple Personal Checklist

When you plug your numbers into a calculator or talk to a lender, ask yourself:

  • Would I still feel comfortable if my income dropped a bit or some expense went up?
  • Am I still saving monthly for retirement and emergencies?
  • Am I okay with sacrificing lifestyle spending to hit the top end of the budget?

If any answer feels shaky, aim for a smaller payment than the maximum.

Use an online home affordability calculator, enter your income, debts, and down payment, and look at the suggested price range and monthly payment.

Is the 28/36 rule still relevant in 2026?

Yes, it’s still widely used as a rule of thumb, even though lenders sometimes accept higher ratios up to the low‑40s for total debt if the rest of your profile is strong.
