How Much House Can I Afford? Calculator
Lenders test whether you could still pay at a higher rate (the stress test) and cap how much of your income goes to housing and debt. This estimate applies those limits and tells you which one is holding you back.

What limits you: housing costs (GDS 39% of income).
Uses the 5.25% floor or your rate plus 2%, GDS 39% and TDS 44% (insured limits). Lenders’ own limits and credit checks differ. An estimate, not pre-approval. Plan for closing costs and land transfer tax on top.
How lenders decide how much you can borrow
Lenders check two ratios at a higher qualifying rate, not your actual rate. Your housing costs (mortgage payment, property tax, heating and half of condo fees) can be at most 39% of gross income (GDS), and all debt payments together at most 44% (TDS). The qualifying rate is the greater of your rate plus 2% or 5.25%: the mortgage stress test. Your down payment must also meet the minimum for the price.
How much house can I afford on $140,000 a year?
With $140,000 of household income, $400 a month in other debts, $100,000 down, $5,000 a year in property tax and a 4.5% rate over 25 years, the stress test uses 6.5% and the most a lender would likely approve is about $684,000, with a mortgage of about $602,104. What holds it back here is housing costs (GDS 39% of income).
| Household income | Maximum price | Mortgage |
|---|---|---|
| $100,000 | $500,000 | $400,000 |
| $140,000 | $684,000 | $602,104 |
| $200,000 | $966,400 | $893,258 |

What this estimate doesn’t include
- Your credit score and history, which every lender checks.
- Lender-specific policies; some lenders use lower limits or count income differently.
- Closing costs (about 1.5% to 4% of the price), which you need on top of the down payment.
- Whether the payment fits your own budget. The maximum a lender approves isn’t the same as what’s comfortable.
