Mortgage Break-Even Calculator Canada
Compare the real cost of breaking or switching a Canadian mortgage against the savings from a new rate, then see the month where the decision starts to pay back.
Compare the cost of switching with the savings that may pay it back
Start with the current balance, current rate, new rate, remaining term, penalty and fees. The decision view then compares monthly payment change, interest impact, total switching cost, break-even timing and net savings over the period you expect to keep the mortgage.
Mortgage inputs
Correct the values below before calculating your break-even result.
These assumptions decide whether the break-even month is useful. A switch can look strong over five years but weak if you expect to sell or refinance again sooner.
The switch only matters if savings recover costs before this point.
Manual is better when you have a lender quote. The 3-month estimate is not exact IRD.
Canadian mortgage prepayment penalties vary by lender and contract. Confirm the actual penalty before making a switching decision.
Quick mortgage notes
A low new rate can still lose if the penalty is too large for the time you expect to stay.
Payment savings and interest savings are related, but they are not always the same decision.
Extending amortization can make the payment look better while adding long-term cost risk.
A lender penalty quote is stronger than any rough prepayment estimate.

Which mortgage option deserves review first?
Compare the current mortgage, switching, financing costs, keeping the same payment, waiting until renewal and negotiating a blend-style option.
A scenario is marked for review only when it materially changes the break-even result, cash flow, interest cost or risk profile. It is not a lender recommendation.

Follow the savings month by month
The monthly table shows cumulative savings against switching cost, so the break-even point is visible instead of hidden inside a headline number.
| Month | Current payment | New payment | Monthly savings | Cumulative savings | Switching cost | Net recovery | Current interest | New interest | Interest difference | Current balance | New balance |

How to use the mortgage break-even calculator
The strongest result comes from using numbers you can verify: the current balance, the actual mortgage rate, a realistic new rate offer, the lender penalty quote, and the time you expect to keep the mortgage.
Start with the current mortgage
Enter the remaining balance, current rate, monthly payment, remaining amortization and months left in the current term. These numbers create the baseline the switch must beat.
Add the new mortgage option
Enter the new rate and new amortization carefully. If the new amortization is longer, the payment may fall partly because the loan is stretched out, not only because the rate is better.
Use a lender penalty quote when possible
The penalty is usually the largest uncertainty. A rough estimate can be useful for planning, but a lender quote is the number that matters before acting.
Compare break-even with expected stay
A switch that breaks even in 42 months may be weak if you expect to sell, refinance again, or reach renewal in 24 months.
Read the verdict before the payment
The lower payment is not always the best signal. Start with the break-even month, total switching cost, net result and Biggest Risk.
Review alternatives before switching
Compare waiting until renewal, negotiating with the current lender, financing costs, or keeping the same payment at the lower rate.
What your mortgage break-even result actually means
A break-even result is not a prediction that switching is automatically the right move. It is a timing test: how long it takes for estimated payment savings to recover the penalty and switching costs.
Break-even month
This is the month where cumulative monthly savings equal the total switching cost. If the break-even month arrives before your expected stay period and before renewal, the switch may deserve serious review.
Total switching cost
This includes the prepayment penalty plus discharge, administration, appraisal, legal, registration, cash-back repayment and other entered costs, minus lender credits.
Net result by horizon
This shows whether estimated savings remain positive after switching costs over the period you selected. A positive number is stronger when it also survives the expected-stay and term checks.
Biggest Risk
The risk is selected from measurable issues such as no monthly savings, break-even after expected stay, penalty uncertainty, term timing, financed costs or amortization extension.
How to decide whether breaking or switching a mortgage is worth reviewing
The decision is strongest when the new option recovers costs quickly, does not depend on a longer amortization to look attractive, and still makes sense if your plans change.
Break-even happens well before expected stay
The switch may deserve review if savings recover costs early and the net result remains positive by the end of the selected horizon.
Break-even is close to expected stay or renewal
A thin recovery window can disappear if the penalty is higher, fees increase, or you move sooner than expected.
The payment falls because amortization is extended
Lower monthly payment can improve cash flow but may hide higher long-term cost if the loan is stretched over more years.
Savings do not recover the penalty and fees in time
Waiting until renewal, negotiating with the lender, or reviewing a same-payment strategy may be cleaner than paying a large penalty now.
Before acting, check four things
A rough penalty estimate can change the result dramatically. Ask the lender for the actual payout penalty.
Compare break-even with expected stay, not just the mortgage term.
A longer amortization may reduce payment while weakening total-cost savings.
Review renewal timing, a blend-and-extend offer, lender retention options or keeping the same payment.
Monthly savings are not the whole mortgage decision
A lower payment can be useful, but it does not always mean the mortgage is cheaper. The break-even result needs to sit beside interest cost, remaining balance and amortization.
Cash flow improves now
A lower payment can make the switch feel attractive immediately. The problem is that penalty and fees may take months or years to recover.
Total cost may tell a different story
If the new amortization is longer or costs are financed into the mortgage, the lower payment can come with a larger balance or more long-term interest risk.
Real mortgage break-even scenarios
The same rate drop can produce very different decisions depending on penalty size, remaining term and how long the borrower expects to keep the mortgage.
Large penalty, short expected stay
A borrower saves $180 per month but faces an $8,500 penalty and expects to sell in two years.
The lower payment feels good, but the recovery period is too long. The borrower may leave the property before the savings catch up.
Main risk: Paying a penalty that is not recovered before moving.Moderate penalty, strong rate drop
A borrower saves $320 per month with $5,000 in total switching costs and plans to stay at least four years.
The break-even period is shorter, so the switch may deserve a closer lender review if the penalty and fees are confirmed.
Main risk: Assuming the advertised rate and closing costs are final.Lower payment caused by longer amortization
The new payment drops sharply because the amortization resets from 17 years to 25 years.
Cash flow improves, but the result needs a total-cost check. The payment drop may not represent true savings.
Main risk: Confusing payment relief with lower mortgage cost.Common mortgage break-even mistakes
Most weak switching decisions come from treating one attractive number as the full answer.
Using a guessed penalty as if it were final
Penalty formulas vary by lender and contract. A lender quote can turn a strong-looking switch into a weak one.
Ignoring expected stay
Break-even after 36 months is not helpful if the borrower expects to sell in 18 months.
Comparing payments with different amortizations
A lower payment is less meaningful when the new mortgage is stretched over a longer payoff period.
Forgetting small fees
Legal, appraisal, discharge and registration fees can add enough cost to push break-even past the useful period.
Why the penalty is treated as an estimate
Canadian mortgage prepayment penalties can vary by lender, mortgage type and contract wording. This page uses your entered penalty as the main input and offers a simple three-month interest estimate only as a planning shortcut. It does not calculate an exact lender IRD.
Ask your lender for the actual mortgage payout penalty, discharge fee, timing rules and any conditions on lender credits before using the break-even result as a decision signal.
How the mortgage break-even calculation works
The calculation estimates the current payment path and the new mortgage path, then compares the monthly savings against the upfront switching cost.
Estimate the current mortgage path
The engine uses the current balance, current rate, payment and remaining amortization to estimate interest, principal and balance over the selected horizon.
Estimate the new mortgage path
The new option is calculated using the new rate, new amortization and current balance. If costs are financed, the new balance increases accordingly.
Add switching costs
Penalty, discharge, administration, appraisal, legal, registration, cash-back repayment and other costs are added, then lender credits are subtracted.
Find the recovery month
Monthly savings are accumulated until they recover the total switching cost. If savings are zero or negative, break-even is not reached through payment savings.
Mortgage break-even questions
These answers focus on how to read the estimate before using lender numbers for a final decision.
Mortgage break-even is the point where estimated savings from a new mortgage recover the penalty and switching costs paid to make the change.
Use it only as a rough planning estimate. Canadian mortgage penalties vary by lender and contract, especially when interest rate differential rules apply.
The payment can fall because the amortization is longer, costs are financed, or the new structure changes the balance path. That is why the result also checks interest, balance and amortization risk.
That usually weakens the switching case. The savings may not recover the penalty and fees before you sell, refinance again, renew, or change plans.
No. It provides a planning estimate and decision framework. Confirm penalty, rates, fees, legal requirements and approval details with qualified professionals and lenders.
