Mortgage affordability calculator: stress test, GDS/TDS ratios and CMHC premium
Know your true buying power.
Income, debts, down payment and rate: Hom24 applies the B-20 stress test and gives you the maximum price you can actually finance.
See it before you sign up
Seven screens from the simulator, captured as-is on a single file: $118,000 gross income, $350 in monthly debts, $105,000 down on a $525,000 property at 4.29%.
The amount you'll actually be lent
Your capacity qualified at the stress-test rate, and the property price it buys once the down payment is added. Here $495,832 borrowable, so a $600,832 maximum price. The contract-rate figure sits beside it, for reference only.
The two ratios that decide
GDS (housing over income, 39% limit) and TDS (housing plus debts over income, 44% limit), computed at the qualifying rate exactly as your lender does. Each with its gauge and its limit on screen.
One price, its ratios, its payment
Drag the slider to the price you have in mind: both ratios and the monthly payment follow live, and a green marker shows where your capacity stops.
Where your income goes
Mortgage, taxes, heating, debts: every share of your monthly income, and above all what is left free at the end. Here $6,147 a month, the number that says whether the project is lived or endured.
The calculation, itemized
The monthly components used in the ratios, at the qualifying rate rather than the contract rate. Nothing hides behind the headline number, including the 50% condo-fee rule.
CMHC premium, in dollars
Below 20% down, loan insurance becomes mandatory. Hom24 computes the premium, its provincial tax and its real monthly cost. On this file: $17,400 added to the loan, or $94 more every month.
The gap to close
When the target price exceeds your capacity, Hom24 says by how much, then prices the ways to close it: extra down payment, extra income, and the 30-year amortization when it is allowed.
A bank's verdict, in 30 seconds
Hom24 mirrors the real rules of Canadian lenders to estimate how much you can borrow.
Precise borrowing capacity
Income, debts and property expenses: get the maximum price you can finance, down payment included.
B-20 stress test
Hom24 qualifies your file at the stress-test rate, exactly like your lender, so there are no bad surprises.
Automatic CMHC premium
Down payment under 20%: the CMHC premium and its monthly impact are calculated and added to the financed amount.
"What if..." scenarios
Raise the income, the down payment or the amortization and watch your capacity move in real time.
Your numbers are already there
The simulator picks up the price, down payment, income and expenses from your analysis. Any field switches to manual in one click, without touching the rest of your file.
A small change, a large gap
Three scenarios in one click: more down payment, a 30-year amortization, or $20,000 more income. Capacity, maximum price and GDS recompute side by side with your real file.
And when it does not pass
A file that fails is not a wall. Hom24 says so plainly, prices the overshoot, and shows what it would take to fit within the limits. Better to learn it at home than at the bank.
The app dresses the way you want
The screenshots on this page are in Desert. The app offers four styles, picked at sign-up and changed whenever you like. Here is the same capacity in each one.
