Does replacing the loan beat keeping it? Net position over the years you will actually stay, the break-even month, and the do-nothing alternative. Everything updates as you type.
The point where a mortgage term ends and the balance comes due. You can renew with the current lender or switch to another; a straight switch keeps the same balance and amortization, so it is not a new purchase.
What is still owed on the loan at a point in time. It is also the payoff amount, before any prepayment penalty or per-diem interest.

Paying a loan down to zero through equal scheduled payments. Each payment covers that month’s interest first; the remainder reduces the balance.
The rate your lender could re-lend at for the months remaining.
Insurance that protects the lender when the down payment is under 20%. It is added to the monthly payment and can usually be removed once you reach about 20% equity.
Renewals do not re-trigger default insurance. Financed at the new rate when set.
The interest rate differential is the greater of the two, so it is the binding rule here. Both are shown so you can check your lender’s figure. A bank using its posted rate minus your original discount can arrive at a much larger differential; only its payout statement is exact.
Modeled as paid upfront, not rolled into the loan.
What this counts: every payment made plus the balance still owed at year 5, keeping the current loan against taking the new one, including $93,500 in costs, prepayment charge included. The new payment is $2,781 a month lower. Break-even arrives in month 25.
Simple calculators divide upfront costs by the monthly saving, which lands on month 34. This one also counts the balance each path leaves you with, which is why its month can differ.
•The prepayment charge is an estimate under the interest rate differential rule. Only your current lender can state the exact figure.
Bars below the line: the refinance is behind. Bars above: it is ahead. The sign change is the break-even point.
The refinance pulls ahead of keeping the current loan at month 25, inside the 5-year horizon.

Refinancing means replacing the mortgage you already have with a new one, usually to get a lower interest rate or to take some of your equity out as cash. Equity is the part of the property you own outright: what it is worth, minus what you still owe. Canadian refinances are capped at 80% of the property's value, and the same 80% limit applies to most US conventional cash-out refinances. Renewal is different. Your term, which is the few years your rate and conditions are locked in for, comes to an end while the loan itself still has years to run, so you sign on for a new term with the same lender or a different one. Either move can carry costs: legal and appraisal work, and a prepayment penalty if you end a term early. This calculator compares the loan you have with the one you are being offered, counts those costs, and shows how many months it takes before the new loan puts you ahead.
Plain-language definitions of every term this calculator uses.
The month a new loan has repaid its own upfront costs, counting both the payments made and the balance still owed on each path. Before it you are behind; every month after it is money ahead.
What a lender charges to end a closed mortgage before its term is up. Canadian lenders charge the greater of three months’ interest and an interest rate differential; US loans rarely carry one. Only the lender’s payout statement is exact.
A prepayment charge priced as the gap between your rate and a current one, applied to the balance for the months left in the term. Which comparison rate the lender uses, posted or discounted, can change the figure several times over.
The point where a mortgage term ends and the balance comes due. You can renew with the current lender or switch to another; a straight switch keeps the same balance and amortization, so it is not a new purchase.
Re-amortizing an existing loan over its remaining term after a lump-sum payment, which lowers the payment without replacing the loan. Lenders treat it as a separate request from a refinance.
What is still owed on the loan at a point in time. It is also the payoff amount, before any prepayment penalty or per-diem interest.
Paying a loan down to zero through equal scheduled payments. Each payment covers that month’s interest first; the remainder reduces the balance.
The number of years the loan is scheduled to run. Shorter terms mean higher payments and less total interest.
Insurance that protects the lender when the down payment is under 20%. It is added to the monthly payment and can usually be removed once you reach about 20% equity.
The lender’s charge for the borrowed money, calculated each month on the remaining balance.
