The only platform that models IRD penalties the way RBC, TD, BMO, Scotia, and CIBC each actually calculate them — then tells you, to the month, when refinancing pays for itself.
Every Big Five bank in Canada calculates the Interest Rate Differential using a different posted-rate benchmark, a different discount lookback, and a different rounding rule. The penalty on the same mortgage can vary by $9,000 from one lender to the next. Generic calculators don't model this. We do — by lender, by branch, by current posted curve.
Paste a renewal letter, upload a PDF, or type the terms. We extract balance, contracted rate, posted rate at signing, term remaining, prepayment privileges, and lender.
We run the lender's actual penalty formula — not a generic IRD. We layer in legal, discharge, appraisal, and CMHC adjustments. We compare against today's discretionary rates for that lender, segment, and LTV.
We monitor the rate curve daily and alert you when a window opens that hits your target breakeven — 12 months, 18, never. You decide the threshold.
Save the rate sheet for the negotiation. Pull a client's discharge statement, model six refinance paths in parallel, hand them a branded PDF before the call is over. Designed by mortgage brokers who got tired of Excel.
Big banks, monolines, credit unions, alternative lenders. 42+ Canadian institutions — and counting.
What Patricia, a homeowner in Halifax, kept in her pocket by waiting four months for the right discharge window — instead of taking the renewal offer her bank slid across the table.
“My broker showed me a number. ClearBreak showed me the number, sourced from my actual lender's formula, with the exact week to lock. We waited. It saved us nearly twelve grand.”
