Is the alternative lender route always cheaper?

In most cases for self-employed borrowers with a significant gap between CRA income and stated income, yes. The tax savings typically outweigh the extra interest cost. However, if the income gap is small, the prime rate could win. This calculator shows you the exact crossover point.

What if I'm already declaring high income to CRA?

If your CRA income already qualifies you for a prime mortgage, then the prime lender is clearly the better choice — you get the lower rate without any additional tax cost. This calculator is most relevant for borrowers whose CRA income is lower than what prime lenders require.

Does this calculator account for the mortgage stress test?

This calculator focuses on the cost comparison between the two paths, not on qualification. The stress test affects how much you can borrow — prime lenders apply the federal stress test, while many B-lenders use their own contract rate for qualification.

Are there additional fees with alternative lenders?

Some B-lenders charge a lender fee (typically 0.5-1% of the mortgage amount) and may require a broker fee. These are usually added to the mortgage balance. Even with fees included, the alternative lender route is typically cheaper when the income gap is significant.

Can I switch from a B-lender to an A-lender later?

Absolutely. Many borrowers use the B-lender as a stepping stone. At renewal (typically 1-3 years), if your income situation has changed, you can qualify to port to a prime lender at a lower rate. This is a very common and effective strategy.

Option A vs Option B: The Real Numbers

Interest savings alone don't tell the full story. You must factor in the extra taxes you'd pay to qualify.

Option A: Prime Lender

Lower rate, but declare higher income

Interest Rate 4.49%

Monthly Payment $2,741

Total Interest (Term) $117,000

Annual Tax (on stated income) $32,388

Extra Taxes vs CRA Income +$82,100

Total Real Cost (Term) $199,100

Interest paid + extra taxes over term

WINNER

Option B: Alternative Lender

Higher rate, but keep taxes low

Interest Rate 5.99%

Monthly Payment $3,173

Total Interest (Term) $142,000

Annual Tax (on CRA income) $15,968

Extra Interest vs Prime +$25,000

Total Real Cost (Term) $142,000

Interest paid only (no extra taxes)

THE VERDICT

$57,100

Alternative lender saves you $57,100 over 5 years when you factor in the tax savings.

The higher interest rate costs more, but it's far less than the extra taxes you'd pay to qualify at a prime lender.

Why Alternative Lenders Often Win for Self-Employed

Most borrowers only compare interest rates. But when you're self-employed, the hidden cost is taxes — and it's usually much larger than the rate difference.

The True Cost Formula:


                                Total Real Cost = Interest Paid + Extra Taxes Over Term

Prime Lender

Lower interest + higher taxes = often MORE expensive

Alternative Lender

Higher interest + lower taxes = often LESS expensive

The Difference

Usually $20K-$80K+ in savings over a 5-year term

Tax Savings Compound

The extra taxes you'd pay to qualify at a prime lender aren't a one-time cost. You'd pay them every year of your mortgage term — $15K-$20K per year adds up fast.

Rate Difference Is Small

The typical spread between A and B lender rates is 1-2%. On a $500K mortgage, that's about $400/month difference — far less than the monthly tax cost of declaring $70K more income.

Transition to Prime Later

Start with a B-lender, build equity, and transition to a prime lender at renewal when your financial picture allows — many borrowers do this within 2-3 years.

Fully Regulated

B-lenders in Canada are fully regulated by FSRA (Ontario) and other provincial regulators. They follow the same consumer protection rules as banks.
