12mortgage_payment
Calculate the periodic mortgage payment for a Canadian home. Call it ONE of two ways: (a) if the user gave a PURCHASE PRICE, pass homePrice + downPayment and CMHC insurance is applied when the down payment is under 20%; (b) if the user gave a MORTGAGE / LOAN AMOUNT (e.g. "payment on a $500,000 mortgage"), pass loanAmount on its own. Do NOT invent a purchase price in order to reach a loan amount — use loanAmount. Inventing a price changes the answer by several percent and attaches a CMHC premium the user does not owe.
minimum_down_payment
Calculate the minimum down payment for a Canadian home under the Dec 2024 CMHC rules (5% on the first $500k, 10% on the portion from $500k–$1.5M, 20% at/above $1.5M), plus whether CMHC insurance applies and the premium rate.
land_transfer_tax
Estimate land transfer tax on a home purchase for all 13 provinces and territories (incl. Toronto MLTT, Montreal welcome tax), first-time buyer rebates, plus the transfer registration fee (the government fee to register the deed) and the total due at registration. Alberta, Saskatchewan, Newfoundland & Labrador and the three territories charge no land transfer tax, only the registration fee. The mortgage registration fee is separate and not included.
income_tax
Calculate 2026 Canadian federal + provincial income tax, CPP/QPP, EI, QPIP (Quebec), Ontario surtax and Health Premium where applicable, plus net (take-home) pay for any province.
mortgage_penalty
Estimate the penalty to break a Canadian mortgage: three months' interest vs the interest rate differential (IRD), including the big-bank posted-rate method. Fixed = greater of the two; variable = usually three months' interest. IMPORTANT: the three rate inputs below are lender-specific and are NOT supplied by most users. If they are omitted, this tool falls back to illustrative site defaults and the answer can be several times too low or too high — the response reports exactly which values were assumed in `assumedInputs`. Always surface those assumptions to the user and tell them to confirm the real figures with their lender.
bc_home_flipping_tax
Estimate British Columbia's home flipping tax on a property sold within 730 days: 20% tapering to 0% between 366 and 730 days, with a $20,000 primary-residence deduction (only if held at least 365 days).
rent_increase
Calculate the maximum allowable annual rent increase under the Ontario LTB, BC RTB or Manitoba RTB guideline for a given year, and the resulting new rent.
capital_gains_tax
Estimate Canadian capital gains tax on a disposition (real estate, stocks, crypto, a business, or a rental property). Applies the flat 50% inclusion rate, the principal-residence exemption, the lifetime capital gains exemption for QSBC shares, capital-loss offsets, and rental CCA recapture — then taxes the taxable gain on top of your other income at federal + provincial brackets.
heloc_second_mortgage
Compare a HELOC against a second mortgage for tapping home equity in Canada. Returns how much you can borrow (revolving HELOC capped at 65% LTV, total secured borrowing to 80% with an A lender), monthly payments, TDS qualification at the OSFI stress-test rate, and the equivalent numbers for B and private lenders.
mortgage_affordability
Work out the maximum home price a Canadian buyer qualifies for: binary-searches the price that keeps both the GDS (39%) and TDS (44%) ratios satisfied at the OSFI stress-test rate, honouring the Dec-2024 minimum down payment tiers and the $1.5M CMHC insurability ceiling. Returns max price, max mortgage, CMHC premium, monthly payment, and the GDS/TDS ratios.
cap_rate
Analyze a Canadian rental property: capitalization rate, net operating income, gross rent multiplier, expense ratio, annual cash flow and cash-on-cash return, plus how the cap rate compares to typical yields in the local market. Mortgage math uses Canadian semi-annual compounding.
house_flipping
Estimate the profit on a Canadian house flip: land transfer tax (with first-time buyer rebate), renovation cost with contingency, holding costs, realtor commission, and closing costs — then the tax bill. Flags the CRA residential property flipping rule (held under 12 months = 100% business income, no capital gains treatment) and shows the tax saving from waiting past the 12-month line.
