Calculator · Should I refinance?

Will switching actually pay back?

Refinancing mid-term costs money - a penalty, legal/discharge fees, sometimes an appraisal. This tool weighs those costs against your monthly savings and tells you the real break-even date and net dollars saved over the new term.

How the calculator works.

  1. Enter your current mortgage.

    Balance, contract rate, and remaining amortization.

  2. Enter the new mortgage terms.

    New rate and amortization you're considering.

  3. Enter the cost of breaking.

    Prepayment penalty plus legal, discharge, and appraisal fees.

  4. Pick a comparison horizon.

    Usually the length of the new term, most often 5 years.

  5. Read your break-even point and net savings.

    See monthly savings, the break-even date, and net dollars saved over the horizon.

Variable vs. fixed, very different math.

On a variable-rate mortgage the penalty to break is almost always three months of interest - a clean, predictable number. On a fixed-rate mortgage, lenders use the interest rate differential (IRD).

The Big-5 banks calculate IRD off their inflated posted rate, which can produce penalties of $15,000–$30,000+. Mortgage finance companies use the rate they actually offer in market - penalties are usually a tenth of that.

Refinancing for non-rate reasons.

Saving on rate is one reason to refi - but plenty of files refinance to pull equity, consolidate high-interest debt, restructure after a life change, or switch from a variable.

This calculator only handles the rate-switch case. For the others, send me your statement and I'll run the actual numbers for your situation.
