How this calculator works
Penalty estimate: For variable mortgages, lenders typically charge 3 months' interest. For fixed mortgages, it's the greater of 3 months' interest or the Interest Rate Differential (IRD) — the difference between your current rate and the lender's current posted rate for a term matching your remaining time, multiplied by your balance and time remaining. Big-6 banks calculate IRD using posted rates, which is why their penalties are much higher than monolines.
Equity available: Refinances are capped at 80% loan-to-value (LTV). Equity available = (home value × 80%) − current balance.
Break-even: The total cost of refinancing (penalty + legal + appraisal) divided by the monthly cash flow improvement. If you'll stay in the home (or keep this mortgage) longer than the break-even, refinancing makes sense.
Debt consolidation: Rolling 19.99% credit card debt into a 4.29% mortgage can save hundreds per month — but only if you don't run the cards back up. The math here assumes the consolidated debt is paid off entirely.
