How do I calculate final closing costs?



Want to know your final closing costs before you sign? Here’s the fast formula that removes surprise fees.

The quick answer

Final closing costs = purchase adjustments + government fees + lender fees + professional fees + prorated expenses + one-time extras. Calculate each line, add them up, and you’ll know exactly what to bring to closing.

Step-by-step formula you can use now

    • Start with the purchase price.
    • Add government fees (land transfer tax, GST/HST where applicable).
    • Add lender fees (appraisal, mortgage application, mortgage insurance if required).
    • Add professional fees (lawyer/notary, title insurance).
    • Add prorated items (property taxes, utilities, condo fees the seller prepaid).
    • Add one-time extras (home inspection, mover, utility hook-ups).

Example (simple):

    • Purchase price: $800,000
    • Land transfer tax estimate (1.5%): $12,000
    • Lawyer & closing costs: $1,500
    • Title insurance: $300
    • Appraisal: $500
    • Adjustments & prepaid taxes: $800
    • Inspection & moving deposit: $900 Final closing costs = $12,000 + $1,500 + $300 + $500 + $800 + $900 = $16,000

Use this as a baseline. Local taxes and lender requirements change totals.

Common line items to watch (and how to estimate them)

    • Land transfer tax: varies by province/municipality. Check local rates or ask your realtor.
    • Legal fees: typically $800–$2,500 depending on complexity.
    • Title insurance: $200–$500.
    • Appraisal: $300–$700.
    • Home inspection: $300–$700.
    • Mortgage default insurance: required for high LTV loans — often a percentage of the mortgage.
    • HST/GST: applies to new builds or certain services.

How to build your closing costs calculator (3-minute method)

    • Create a table with the line items above.
    • Plug in either exact quotes or conservative estimates.
    • Sum the totals and add a 5–10% buffer for surprises.

Tip: keep the buffer. Sellers and lenders adjust numbers at the last minute.

Why this matters — and what I do differently

I cut the guesswork. I run a localized closing-cost estimate for every client based on current municipal taxes, lender requirements, and real legal quotes. That eliminates surprises and gives you a real number to bring to the bank.

Actionable next steps

    • Download or build a simple spreadsheet using the formula above.
    • Ask your lender for a Good Faith Estimate and compare line by line.
    • Contact a local lawyer early — quote turns into final legal fees.

For a precise, no-nonsense closing-cost calculation tailored to Toronto and surrounding markets, reach out. I’ll run the numbers and send a clear, itemized estimate so you know exactly what to bring to closing.
