Tools 34

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).

Discovered
bc_rescission_period

British Columbia's 3-business-day home buyer rescission period: the deadline (11:59 p.m. on the third business day after acceptance, skipping weekends and BC statutory holidays) and the 0.25% fee to rescind.

Discovered
cap_rate

Canadian rental property analysis: cap rate, net operating income, gross rent multiplier, expense ratio, annual cash flow and cash-on-cash return, with the cap rate compared to typical local yields. Mortgage math uses Canadian semi-annual compounding.

Discovered
capital_cost_allowance

CRA capital cost allowance on a business or rental asset: class rate, year-1 CCA (half-year rule, AIIP or the post-2024 accelerated incentive, by acquisition date), tax saving at your marginal rate, a 5-year schedule, and recapture or terminal loss on disposal.

Discovered
capital_gains_tax

Estimate Canadian capital gains tax on selling real estate, stocks, crypto, a business or a rental. Applies the flat 50% inclusion rate, principal-residence exemption, lifetime capital gains exemption for QSBC shares, capital-loss offsets and rental CCA recapture, then taxes the gain on top of other income at federal + provincial brackets.

Discovered
closing_costs

Cash needed to close a Canadian home purchase in any province or territory: land transfer tax (with first-time-buyer rebates, Toronto MLTT, NRST), land title and mortgage registration fees (listed separately), CMHC premium + PST, legal/inspection/appraisal/moving allowances, new-build GST/HST.

Discovered
cmhc_insurance

CMHC (mortgage default insurance) premium for any down payment under 20% on a Canadian home: premium rate and amount added to the mortgage, provincial sales tax on the premium (ON, QC, SK — paid in cash at closing), and the insured mortgage total.

Discovered
cost_of_selling

Total cost of selling a Canadian home and what you walk away with: commission + GST/HST (province starting rates, all overridable), legal fees, mortgage discharge fee and other costs, then net proceeds after the mortgage is paid off.

Discovered
debt_service_ratio

Gross (GDS) and total (TDS) debt service ratios from income, housing costs and other debts, against the 39% / 44% limits. Condo fees count at 50%. Use the payment at the stress-test rate for a qualifying view.

Discovered
debt_to_income

TDS from income, housing costs and an itemised debt list. Credit cards and lines of credit with no payment given default to 3% of the balance; car and personal loans need their real payment. Returns total balance, payments, available credit and GDS/TDS vs 39% / 44%.

Discovered
heloc_second_mortgage

Compare a HELOC with a second mortgage for tapping home equity in Canada: 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 same for B and private lenders.

Discovered
house_flipping

Estimate profit on a Canadian house flip: land transfer tax (with first-time buyer rebate), renovation 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 the tax saved by waiting past 12 months.

Discovered
house_hacking

Live in one unit and rent the rest (basement suite, duplex/triplex, rooms, ADU): mortgage with CMHC, ownership costs, rent after vacancy, your true monthly cost vs renting, and the income needed to qualify with and without rental add-back.

Discovered
income_tax

2026 Canadian federal + provincial income tax, CPP/QPP, EI, QPIP (Quebec), Ontario surtax and Health Premium where applicable, and take-home pay, for any province.

Discovered
insured_insurable_uninsured

Broker tool: classifies a mortgage as insured, insurable or uninsurable (purchase, renewal, switch, refinance) with reasons, then GDS/TDS in each category at its rate. Renewals depend on whether a premium was paid at origination.

Discovered
land_transfer_tax

Estimate land transfer tax on a home purchase in any of the 13 provinces and territories (incl. Toronto MLTT, Montreal welcome tax) with first-time buyer rebates, the transfer registration fee (to register the deed) and the total due at registration. AB, SK, NL and the territories charge no land transfer tax, only the registration fee. The mortgage registration fee is not included.

Discovered
minimum_down_payment

Minimum down payment for a Canadian home under the Dec 2024 CMHC rules (5% of the first $500k, 10% of $500k–$1.5M, 20% at/above $1.5M), whether CMHC insurance applies, and the premium rate.

Discovered
mortgage_affordability

Maximum home price a Canadian buyer qualifies for: the highest price that keeps GDS (39%) and TDS (44%) within limits 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 GDS/TDS.

Discovered
mortgage_amortization

Year-by-year amortization of a Canadian mortgage (semi-annual compounding): payment, total interest, balance at renewal, payoff year, and an annual table. Optional lump-sum / payment-increase prepayments show interest and time saved.

Discovered
mortgage_payment

Periodic payment on a Canadian mortgage. Pass EITHER homePrice + downPayment (CMHC insurance is added under 20% down) OR loanAmount alone when the user gave the mortgage amount (e.g. "payment on a $500,000 mortgage"). Never invent a purchase price to reach a loan amount: it shifts the answer and adds a CMHC premium the user may not owe.

Discovered
mortgage_penalty

Estimate the penalty to break a Canadian mortgage: three months' interest vs the interest rate differential (IRD), incl. the big-bank posted-rate method. Fixed = greater of the two; variable = usually three months' interest. The three optional rate inputs are lender-specific: if omitted, illustrative site defaults are used (the answer can be several times off) and listed in `assumedInputs` — show them to the user and have them confirm with their lender.

Discovered
mortgage_prepayment

Interest and time saved by prepaying a Canadian mortgage with extra per-payment amounts, an annual lump sum, or both, plus the estimated penalty if the prepayment were over your privilege limit (3 months' interest or IRD).

Discovered
mortgage_qualifier

Maximum mortgage and home price at the OSFI qualifying rate. mode='income': from income, debts and down payment, limited by GDS 39% / TDS 44%. mode='budget': from a monthly payment you can afford. Property tax and heating are estimated.

Discovered
mortgage_renewal

Compare a Canadian mortgage's payment and term interest at the current rate vs the renewal rate: new payment, monthly and annual change, and extra interest over the new term. An optional lump sum at renewal reduces the balance.

Discovered
mortgage_stress_test

Check a purchase, renewal or refinance against the OSFI stress test: qualifying rate (higher of contract + 2% or 5.25%), GDS/TDS at 39/44, pass/close/fail, max home price for a purchase, and how far off a fail is. Straight-switch renewals are exempt unless the amount or amortization increases.

Discovered
property_development

Development pro forma for a Canadian build: land + land transfer tax, hard costs, soft costs, HST net of the new-housing rebate, construction financing, contingency, sale proceeds, profit, margin and ROI.

Discovered
property_tax

Annual and monthly property tax from ASSESSED value (not purchase price — Ontario still uses 2016 MPAC values) for 18 Canadian cities, each published rate normalised to full assessed value (SK taxes 80%, Winnipeg 45%). Pass ratePct instead of city to use the rate on your own bill.

Discovered
real_estate_commission

Seller's real estate commission in Canada: commission, GST/HST on it, listing vs buyer brokerage split, and net proceeds. Province sets commonly quoted starting rates (AB/BC tiered, ON/MB flat). Commission is NOT regulated — every rate is negotiable and can be overridden.

Discovered
renovation_roi

Return on a home renovation: value added vs cost, and how that value shrinks by the time you sell (straight-line over the project's economic life — an editable HomeCalc assumption, not a measured figure), plus any net rent the work earns.

Discovered
rent_increase

ON/BC/MB rent-increase guideline and new rent, floored to the cent. capped:false = exempt unit.

Discovered
rent_vs_buy

Compare renting with buying over a time horizon: net cost and net wealth of each (home equity after selling vs the renter investing the down payment and monthly savings), the break-even year, and milestone years.

Discovered
reverse_mortgage

Reverse mortgage (CHIP-style) for homeowners 55+: theoretical maximum (55% of value — the lender's published ceiling, not your approval), and how the balance compounds (semi-annually, no payments) vs home equity at 5/10/15/20 years.

Discovered
second_home_affordability

Maximum price for a second property (cottage, rental or second home) while keeping your current home: combined TDS across both properties, subject-property GDS, minimum down payment (20% unless you'll live in it), optional rental income add-back.

Discovered
seventy_percent_rule

Maximum purchase price for a flip under the 70% rule (or the stricter 65%): ARV × rule − repairs, plus the profit left after repairs and the commission and closing costs on the sale.
