When you decide to sell, the first question almost everyone asks is: “How much will I actually walk away with?”
The calculator in the hero section is built to answer that. It helps you estimate the total costs that will be deducted on closing — commission, tax, legal fees, and any mortgage penalties — so you can see a realistic number instead of guessing.
This page explains how the tool works, what it includes, and how to interpret the results when you are planning your sale.
The tool is meant to give Canadian sellers a quick, honest estimate of their transaction costs. It focuses on the major expenses that almost every seller faces:
Lawyer or notary fees
Sales tax on those services
Mortgage discharge
Mortgage penalty costs
Condo estoppel/status certificate
You adjust the sale price, commission rate, legal fees, any penalty amount, discharge, and condo estoppel/status certificate fee and the calculator shows the total deductions from your sale proceeds. Think of it as a simple way to estimate the cost of selling, without needing a spreadsheet.
The calculator uses four inputs plus a province selector. Here’s what each piece does.
The first drop-down sets:
The applicable sales tax rates for your region (including GST, HST, QST, and any applicable PST or RST on commissions and legal fees).
The commission structure defaults (simple percentage vs. typical tiered models).
Options include:
Ontario
British Columbia
Alberta
Saskatchewan
Manitoba
Quebec
Nova Scotia
New Brunswick
Prince Edward Island
Newfoundland
A custom option for situations that don’t fit neatly into those presets
Behind the scenes, each province has its own tax rate and, in some cases, common tiered commission structures.
You can work two ways:
Slider mode: Good for quick estimates and “what-if” scenarios.
Manual input: Lets you type exact figures from a listing agreement, lawyer quote, or mortgage payout statement.
The toggle simply switches which fields are visible. The math stays the same.
This is your expected sale price. It’s the base number used to calculate commission.
In “flat” markets: This is the overall percentage charged on the full price.
In markets with tiered structures: This is the rate on the balance after the first tiers have been applied.
You can change this value to reflect different service models (traditional full-service, reduced commission, flat-fee equivalent, etc.).
This input covers the total cost of hiring a lawyer or notary to handle the transaction. It is important to know that legal bills are typically split into two parts:
Professional Fee: The cost for the lawyer’s time and expertise.
Disbursements: Out-of-pocket expenses the lawyer pays on your behalf (e.g., title search fees, courier charges, software registration fees, and bank transfer costs).
Recommendation: When calling law firms, ask specifically for an “all-inclusive quote” that covers both the professional fee and all expected disbursements. Many lawyers will quote a low base fee (e.g., “$999”) but add disbursements later, which can inflate your final bill by $300 to $600. By entering an all-inclusive figure here, your estimate will be much more accurate.
Typical Range: For a standard sale in Canada, an all-inclusive total often ranges between $1,000 and $1,800, though this varies by province and complexity.
Applies only to: Sellers of condominiums or strata units. The typical fee for a condo estoppel/status certificate is around $100-$300. The seller usually pays the fee, which covers the cost for the condo board or management company to compile the required information about the unit’s financial status.
If you are paying off a mortgage early, your lender may charge:
A prepayment penalty,
A discharge fee, or
Both.
This field lets you plug in that amount. The calculator treats it as non-taxable and adds it on after the tax calculation. A standard administrative discharge fee is typically $200–$400. However, prepayment penalties vary by lender and can range from thousands to tens of thousands of dollars.
Note: Fees charged by lenders to process the discharge of a mortgage are typically considered a financial service, which is generally exempt from GST/HST or PST. Federally regulated lenders are required to disclose these fees in your mortgage contract.
Your calculator results are broken into four lines:
Commission
Legal fees
Tax on those services
Mortgage penalty
Then it shows one combined figure: Total Deducted. Here’s how each part is calculated.
For most provinces (flat structure):
For British Columbia and Alberta (Common Tiered Examples):
7% on the first $100,000 of the price
The rate you choose (the “balance rate”) on the remainder
Disclaimer: Commission rates and structures are not set by law; they are negotiable and vary by brokerage and agent.
For Saskatchewan (Common Tiered Example):
6% on the first $100,000
4% on the second $100,000
The chosen balance rate on anything above $200,000
These patterns reflect common brokerage structures in those markets, but you are free to adjust the rates to match your specific agreement.
Only commission + legal fees are taxed.
Based on your province selection, the tool multiplies that figure by the appropriate tax rate (GST, HST, QST, or combined provincial taxes) and shows the result in the “Tax” line.
The penalty number you enter is displayed separately and not taxed in the calculation. It’s treated as its own line item.
This is the number most sellers care about: the combined closing costs that will come out of their sale proceeds.
Here’s a simplified example so you can see how the numbers fit together.
Scenario:
Property Type: Single Detached House
Province: Ontario
Expected sale price: $900,000
Commission rate: 5%
Legal fees: $1,500
Condo Estoppel/Status Cert: $0
Mortgage penalty: $5,000
HST: 13%
Commission
Taxable amount (commission + legal fees)
HST on taxable amount
Total deducted
Commission: $45,000
Legal fees: $1,500
HST: $6,045
Mortgage penalty: $5,000
Mortgage discharge fee: $200
Total deductions = $57,745
Net proceeds
The calculator shows the “Total deducted” portion; you or your advisor can then subtract your outstanding mortgage for a full net figure.

Included in the calculation:
Real estate commission (flat or tiered, depending on province inputs)
Legal or notary fees (based on your entry)
GST/HST/PST/QST on those services
Any mortgage penalty (entered by you)
Discharge Fee (assumes $200)
Condo estoppel/status certificate – (entered by you for condo owners)
Not automatically included:
Some costs are highly variable or paid before closing, so they’re not baked into the formula:
Staging, photography, or virtual tours: Often paid upfront.
Repairs and pre-listing renovations.
Moving expenses.
Property tax, condo fee, or utility adjustments: These are calculated to the exact day of closing.
Capital gains tax: Only applicable on investment properties or secondary residences (not your primary home).
You can still use the calculator output as a base and then add any of these items separately in your own budgeting.
Even with a national overview, selling costs are not identical from province to province. A few reasons:
Different tax systems: Some provinces use HST, some use GST plus a provincial sales tax (PST/RST/QST), and the rates differ. Furthermore, some provinces tax legal fees and commissions differently.
Commission structures: Tiered models are more common in certain Western provinces, while others primarily use a flat percentage.
Professional fees: Whether you are working with a lawyer or a notary, and local market norms, will affect the quote you receive.
That’s why the first step in the tool is selecting your province. It ensures that the tax piece of your estimate is roughly aligned with how your region works.
Even careful sellers are sometimes caught off guard by a few items:
Higher-than-expected mortgage penalties when breaking a fixed term.
Tax on services (commission and legal fees) that was never factored in mentally.
Small administrative charges from lenders and law offices.
Condo-specific charges such as elevator bookings or status certificate delays.
Using the calculator forces you to think about these line items up front instead of discovering them a week before closing.
Q: Does this tool tell me my exact net proceeds?
A: It tells you the combined deductions related to commission, legal fees, tax on those services, and any penalty you enter. To estimate net proceeds, subtract that total and your mortgage balance from your expected sale price.
Q: Can I use it if I’m selling a condo instead of a house?
A: Yes. The math is the same for condos, townhouses, semis and detached homes. You just plug in the realistic sale price and your expected fee structure.
Q: What if my commission structure is different from the presets?
A: You can adjust the commission rate for the “balance” portion, or choose the custom option if you’re working with an unconventional agreement. The tool is flexible enough for most real-world scenarios.
Q: Are all seller costs included?
A: No. The focus is on major, predictable items: commission, legal, tax on those, and penalties. Things like staging, repairs, and moving are left out so you can add them based on your own plans.
Q: Is this a substitute for legal or tax advice?
A: No. It’s a planning tool. For final numbers, you should confirm with your lender, lawyer/notary, and tax professional.
Real estate transactions are regulated, and the financial impact of selling a property can be significant. This calculator and guide are provided for general information only. They do not replace professional advice from a licensed real estate agent, lawyer or notary, mortgage professional, or tax advisor.
Actual closing costs will depend on the terms of your listing agreement, your mortgage contract, provincial rules, and the professionals you hire. Always verify your expected numbers with the relevant parties before making decisions about listing or accepting an offer.
