  • Scenario 1: Financial Impact Curve

This chart links housing affordability to your financial outlook, showing how costs over disposable income impact your potential investments. It **excludes home equity**, focusing on wealth dips or gains to suggest affordability.

# Years from Now

Try your numbers:


Enter your total annual household income before taxes. This is the basis for evaluating affordability and determining how much of your earnings can sustainably cover housing and other expenses.

A =

Enter the total cost of the house you’re considering. This value determines the mortgage amount and property tax, key contributors to your recurring housing expenses.

B =

Enter the percentage of the house price you’ll pay upfront (min 5%). Less than 20% adds CMHC insurance costs. Higher down payments lower loan size and monthly payments, improving affordability.

C =

Enter the annual interest rate for your mortgage loan. This directly affects your monthly mortgage payment and the total cost of homeownership over time.

D =

Enter your current monthly property maintenance costs and the expected annual percentage increase. This includes recurring expenses like repairs and upkeep, adjusted for inflation or market trends over time.

Ẽ =

Enter the annual tax rate as a percentage of your house price. Property taxes are a recurring cost that scales with the house value and influences affordability; the amounts typically track inflation for municipal and school services.

F =

Enter your average monthly non-housing expenses, such as groceries, utilities, and entertainment, along with the expected yearly growth rate. These inputs ensure accurate projections for total spending over time.
