Smith Manoeuvre Calculator
Model Your Tax Savings in 60 Seconds
The Smith Manoeuvre is a CRA-compliant strategy that converts your non-deductible mortgage interest into tax-deductible investment debt.
This allows you to build wealth using equity you're already creating, without changing your monthly budget.
Instead of simply paying down your mortgage, you re-borrow the equity you've built and invest it in income-generating assets. The interest on that investment loan becomes tax-deductible — reducing your taxable income each year.

How it works: Each month, 100% of your principal payment is re-borrowed from your HELOC and invested in a diversified portfolio. Because the HELOC is used to earn investment income, the interest becomes tax-deductible.
Tax refunds: Each year, your CRA refund (based on your marginal tax rate × HELOC interest paid) is automatically applied as a lump-sum mortgage prepayment, re-borrowed from the HELOC, and invested — accelerating how fast you convert non-deductible debt into deductible debt and building your portfolio faster.
