Lump-Sum Payment
A lump-sum payment is a one-time extra payment applied directly to your mortgage principal, on top of your regular scheduled payment..
A lump-sum payment is a one-time extra payment applied directly to your mortgage principal, above and beyond your regular scheduled payment. Because it sits outside your regular payment schedule, it reduces the balance you owe rather than covering accrued interest first.
How lump-sum payments work in Canada
Most closed Canadian mortgages only permit extra payments through a prepayment privilege, a contractual allowance described in your mortgage commitment. Lenders commonly express that allowance as a percentage of the original principal balance each year, though some set a fixed dollar amount instead. Paying more than the allowance on a closed mortgage can trigger a prepayment penalty, calculated as the greater of three months' interest or the interest rate differential (IRD). Open mortgages generally allow extra payments without a penalty, in exchange for a higher interest rate.
Why it matters to a borrower
Mortgage interest in Canada is charged on the outstanding balance, and fixed-rate mortgages typically compound semi-annually. Every dollar of principal you remove stops generating interest for the remaining amortization period. That makes a lump-sum payment most powerful early in the mortgage, when the balance is largest and the remaining term is longest. The same payment made near the end of an amortization period saves comparatively little.
Options for paying a mortgage down faster:
- Lump-sum payment — a single, optional amount you choose, subject to the prepayment privilege.
- Higher regular payment — an increased payment every period, which raises your ongoing obligation.
- More frequent payments — accelerated payments effectively add extra payments over the year.
What to check before you pay
Confirm whether your mortgage is open or closed, what your annual prepayment privilege is, and whether a lump sum must be made on a scheduled payment date. On many closed mortgages, a lump-sum payment reduces the balance and shortens the amortization period but leaves the regular payment unchanged; some lenders will re-amortize on request. Ask whether the payment is applied to principal immediately and request written confirmation of the new balance. A mortgage prepayment calculator can show the effect on interest and payoff timing before you commit.
Frequently asked questions
Does a lump-sum payment lower my monthly mortgage payment?
Usually not automatically. On many closed mortgages a lump-sum payment reduces your principal balance and shortens your amortization period, while the scheduled payment stays the same. If you want a lower regular payment, ask your lender whether it will recalculate or re-amortize the mortgage, and confirm any conditions in your mortgage documents.
How much can I pay as a lump sum without a penalty?
It depends on your lender and your mortgage contract. Most closed mortgages allow extra payments up to a set limit, often expressed as a percentage of the original principal, and anything above that can trigger a prepayment penalty. Check your mortgage commitment or ask your lender for the current allowance.
Is it better to make a lump-sum payment or increase my regular payment?
Both reduce principal, but they behave differently. A lump sum is flexible, since you choose when and how much within your prepayment privilege. A permanently higher regular payment locks in the extra amount every period and may save slightly more interest, but it also raises your required obligation if your budget tightens.
