HOW IT WORKS

How we calculate your affordability

Three simple steps — the same approach most lenders use to decide what you can borrow.

1. The 28/36 rule (or DTI guideline)

Lenders look at two ratios:

  • Front-end ratio: your housing payment (principal, interest, tax, insurance) should be under 28% of gross monthly income.
  • Back-end ratio (DTI): all debt payments combined — including housing — should be under 36% of gross monthly income.

These are guidelines, not rules. Some lenders allow up to 43% DTI; others stay below 36%. This calculator uses a conservative 36% DTI as a starting point, and adjusts by country.

💡 Just because a lender approves a certain amount doesn't mean you should borrow it. Use this calculator to find a comfortable number, not just a maximum.

2. Working backwards from your budget

We start with your monthly income, subtract your existing monthly debts, and apply the DTI ratio to get a maximum monthly housing budget. From that, we subtract estimated property tax, home insurance, and HOA fees. What's left is the maximum monthly principal & interest payment — which we convert into a loan amount using the standard mortgage formula.

Max housing budget = (Gross monthly income × DTI) − Existing monthly debts
Max P&I payment = Max housing budget − (Tax + Insurance + HOA)
Max loan amount = P&I × [(1+r)ⁿ − 1] ÷ [r × (1+r)ⁿ]

3. Adding your down payment

The final step is simple: your affordable home price is the maximum loan amount plus your down payment.

✓ Your affordable home price = Maximum loan amount + Your down payment

4. What this doesn't include

  • Closing costs: budget 2%–5% of the home price for legal fees, registration, stamp duty, and lender fees.
  • Moving and setup costs: often overlooked — can add thousands.
  • Maintenance: budget 1% of home value per year for repairs and upkeep.
  • Emergency reserves: keep 3–6 months of expenses in cash after closing.
  • PMI or LMI: if your down payment is below 20% in the US, Canada, or Australia.

5. How the ratios vary by country

  • US: 28/36 rule. Lenders may allow up to 43% DTI; below 36% is safest.
  • UK: Lenders typically cap at 4–4.5× income, plus affordability stress tests.
  • Canada: Gross Debt Service (GDS) under 32%, Total Debt Service (TDS) under 40%.
  • Australia: Lenders look at a 30%–35% total debt ratio, plus a buffer on interest rates.
  • India: FOIR of 40%–55% depending on income and employment type.

6. Where people go wrong

  • Borrowing the maximum. Approvals don't leave room for surprises.
  • Ignoring property tax. It varies hugely by location — and can add hundreds to your monthly payment.
  • Forgetting maintenance. A home costs far more than just the mortgage.
  • Not budgeting for closing costs. 2%–5% of the price, paid upfront.
  • Stretching income assumptions. Use stable, verifiable income — not your best-case bonus.

7. Final thoughts

Affordability is personal. The math gives you a range; only you can decide what feels comfortable. A slightly smaller home or a slightly longer savings runway can mean decades of financial breathing room.

Use this calculator as a starting point. Then talk to a lender, verify the numbers, and — most importantly — leave yourself a buffer.

WHAT MATTERS

Three numbers that decide your affordability

Focus on these to understand your home-buying power.

Your income

The biggest single driver. Higher stable income directly translates to a larger affordable home price.

Existing debts

Every rupee, dollar, or pound of monthly debt reduces what you can spend on a home. Clear small debts before buying.

Interest rate

Lower rates mean you can afford a more expensive home for the same monthly payment. Even 0.5% matters.

QUESTIONS

Frequently asked questions

Over 35 common mortgage affordability questions, answered for a global audience.

As a rule of thumb, your total monthly housing payment should stay under 28% of your gross monthly income, and all debts combined under 36%. This calculator uses these guidelines (adjusted by country) to estimate your affordable home price.

A common guideline: your housing costs should be under 28% of gross monthly income (front-end ratio), and all debt payments combined — including housing — under 36% (back-end ratio or DTI). It's a conservative standard; some lenders allow up to 43%.

No. Eligibility is the maximum a lender will approve, based on their risk tolerance. Affordability is what fits comfortably within your real budget. Affordability is usually lower — and safer.

We take your gross monthly income, apply a DTI ratio (default 36%), subtract existing debts to find your maximum housing budget, then subtract property tax, insurance, and HOA fees to find the maximum principal and interest payment. From that, we reverse-calculate the maximum loan amount. Add your down payment, and that's your affordable home price.

36% is a safe, conservative default. Some lenders approve up to 43%, and in some markets (like India) FOIR can go up to 55% for strong borrowers. But a lower DTI leaves more breathing room in your budget — especially against future rate changes or income disruption.

Yes — significantly. Property tax rates vary from ~0.3% (Hawaii) to ~2.5% (New Jersey) in the US. On a $400,000 home, that's a difference of $800/month. High-tax areas reduce the price you can afford for the same monthly budget.

HOA fees directly reduce what you can spend on the home itself. A $500/month HOA fee is like adding $85,000 to your loan at current rates. If you're considering a condo or managed community, factor this in.

Lenders typically count 50%–100% of documented, consistent bonus income. But for personal affordability, it's safest to base your decision on base salary only. That way, a lower-than-expected bonus year doesn't put you under pressure.

Yes, significantly. Combining incomes typically increases affordability by 50%–100%, depending on the co-applicant's income and debts. This is often the single biggest lever available.

A longer loan term means a lower monthly payment for the same loan amount — which means you can afford a more expensive home. But you'll pay much more total interest. A 30-year term increases affordability by ~15%–20% versus a 15-year term at the same rate.

20% avoids PMI (US), CMHC insurance (Canada), and LMI (Australia). But it's not always the right choice — in a rising market, waiting to save 20% can cost you more than the insurance premium. The right answer depends on your market and timeline.

No. Rent is not counted as a "fixed obligation" by lenders in most countries, because it disappears once you own a home. Only loan EMIs, credit card minimums, and co-signed loans reduce your affordability.

Use your average over the last 2–3 years — not your best month. Lenders do the same for self-employed borrowers, often applying a 10%–20% discount for stability. Being conservative here protects you if a slow period hits.

No. Closing costs are separate — typically 2%–5% of the home price, paid upfront. On a $400,000 home, that's $8,000–$20,000. Budget for them in addition to your down payment.

Private Mortgage Insurance (US) is required when your down payment is below 20%. It typically costs 0.3%–1.5% of the loan amount per year, reducing what you can spend on the home. Canada has CMHC insurance, Australia has LMI — all similar in effect.

It depends on your market, timeline, and life stage. Buying usually wins if you plan to stay 5+ years; renting wins if you need flexibility. Use the Buy vs Rent calculator to compare scenarios with your actual numbers.

Aim for 3–6 months of living expenses in an emergency fund, separate from your down payment. New homeowners often underestimate the one-off costs (furniture, repairs, taxes) that hit in the first year.

It usually means one of three things: your income is low relative to home prices, your existing debts are eating into your budget, or you need more down payment. Each has a path — increase income, clear debts, save more, or look at a different location or type of home.

Yes, but affordability is tighter. A single income has less buffer, so it's especially important to keep your housing cost below 28% and maintain a healthy emergency fund. Some markets are simply not affordable on one median income.

In the US, mortgage interest and property tax may be deductible if you itemize. In India, home loan interest is deductible under Section 24(b) up to ₹2 lakh per year. Tax benefits reduce the effective cost, but they don't change what a lender will let you borrow.

Indirectly, yes. A better credit score gets you a lower interest rate — which means you can afford a more expensive home for the same monthly payment. On a $400,000 loan, 0.5% lower rate is roughly $120/month — worth about $20,000 more home.

30 years maximizes affordability (bigger loan for the same monthly payment). 15 years minimizes total interest. If you can comfortably afford the 15-year payment, it saves six figures over the life of the loan. If it stretches your budget, 30 years is safer.

Yes — and it's often overlooked. Budget 1% of home value per year for maintenance and repairs. On a $400,000 home, that's $4,000/year (~$333/month). This isn't part of your mortgage payment, but it's part of what you can truly afford.

Yes, but student loan payments reduce your DTI headroom, which reduces what you can afford. If your student loan payments are high relative to your income, consider paying them down before buying, or expect a smaller home budget.

Some lenders will count projected rental income, but only with documented leases and often at 50%–75% of the actual rent. This calculator doesn't include rental income — add it to your annual income field as a rough estimate, but be conservative.

Enormously. Property tax, insurance, and home prices vary widely by city — even within the same country. A home that's affordable in one city might be out of reach two hours away. Adjust the inputs to model your target location.

Rates change constantly. The calculator shows typical default rates by country (e.g., 6.5% for US 30-year fixed, 5.25% for UK). For current rates, check with 2–3 lenders and use the best offer.

For personal affordability, we recommend using your base salary only. That way, a slower bonus year doesn't put pressure on your mortgage payment. If you're confident about consistent bonuses, you can include them — but always leave a buffer.

Yes. Pick your country, and the calculator automatically switches currency symbol, number formatting, default interest rate, default loan term, and local terminology.

No. This calculator gives an estimate based on standard ratios and typical costs. Real affordability depends on your lender's specific criteria, your actual budget, and local market conditions. Always verify with a lender.
