Every number on this site comes from one tested engine fed with dated rules: the City of Calgary's 2026 tax rate and assessment roll, Alberta's Land Titles schedule, CMHC's premiums and limits, OSFI's stress test, the City's utility rates and Alberta's regulated energy prices. Each rule shows its source and checked date.

Which formulas do the calculators use?
Mortgage payment: level payment on (price − down payment + CMHC premium) at the quoted rate with semi-annual compounding: periodic rate = (1 + r/2)^(2/n) − 1 for n payments a year. Source: Justice Laws, Interest Act, R.S.C. 1985, c. I-15, s. 6. Checked .
CMHC premium: premium rate for the loan-to-value band × the base loan, +0.20 points above a 25-year amortization; no Alberta sales tax. Source: CMHC, Mortgage loan insurance cost (premium table). Checked .
Tax adjustment: if possession falls after June 30 (the seller has paid), buyer pays annual tax × days from possession to Dec 31 ÷ days in year; otherwise the seller credits annual tax × days from Jan 1 to the day before possession ÷ days in year.
City utilities: water $/m³ × use + water charge + wastewater $/m³ × 88% of use + wastewater charge + stormwater + carts. Reproduces the City's typical bill of $119.21 at 19 m³ exactly. Source: City of Calgary, Residential water rates and billing (2026), effective January 1, 2026. Checked .
Qualifying: GDS = (payment at max(rate + 2, 5.25%) + tax + heating + 50% of condo fee) ÷ gross monthly income ≤ 39%; TDS adds other debts ≤ 44%. Heating = 60% of the energy estimate (our assumption). Source: CMHC, Calculating GDS / TDS (heating, 50% of condo fees). Checked .
Solvers (budget and income maximum price) bisect the price over the full model to the nearest $1,000.
How are the community and home-type medians built?
Source: City of Calgary, Current Year Property Assessments (Parcel), dataset 4bsw-nn7w, 2026 roll (valuation date 2025-07-01), retrieved 2026-11-01. Contains information licensed under the Open Government Licence – City of Calgary. Method: Residential (RE) land-and-improvement accounts only. Detached = R110+R111, semi/duplex = R120+R121, townhouse = R401+R402, apartment condo = R201+R301. Medians shown only where at least 5 accounts; quartiles where at least 20. Medians and counts use completed homes only (built ${COMPLETE_BY} or earlier): homes built in 2025-26 or with no build year were assessed partly built at Dec 31, 2025 and are counted separately as newHomes. 'Residual' sub-areas are excluded. Communities with fewer than 25 completed homes in these groups are omitted. Assessed values are the City's estimates of market value, not sale prices.

The City groups detached houses with semis and duplexes, and townhouse units with apartment units, so its medians sit between ours. Our medians come from the open 2026 roll and count only completed homes (built 2024 or earlier); homes assessed partly built at December 31, 2025 are left out.
