Should I put a lump sum down at renewal?

Putting a lump sum down at renewal reduces your principal directly, which lowers your monthly payment and reduces the total interest you pay over the remaining amortization. Use this calculator to see exactly how much you save in interest and how many years you could pay off your mortgage earlier.

What is an accelerated bi-weekly payment?

Accelerated bi-weekly payments divide your monthly payment by two and deduct that amount every two weeks. Because there are 26 bi-weekly periods in a year rather than 24, you effectively make one extra monthly payment per year, which reduces your amortization and total interest significantly.

How much does a higher renewal rate cost?

Even a 1% rate increase at renewal can add hundreds of dollars per month to your payment and tens of thousands of dollars in total interest over the remaining amortization. Use the scenario comparison to see exactly what different rates mean for you.

About This Mortgage Renewal Calculator

Renewing your mortgage is one of the most important financial decisions you will make every few years. Even a small difference in rate, or a lump sum payment at renewal, can mean tens of thousands of dollars in interest savings over your remaining amortization. This calculator is built specifically for the renewal moment — not just payment comparison, but the full picture of what your options actually cost or save you.

Lump sum prepayment at renewal

Renewal time is one of the best moments to put extra money against your principal. Unlike during a term when prepayment may have limits, most lenders allow prepayments at renewal without penalty. This calculator shows you exactly how much interest you save and how many years you could pay off your mortgage earlier by putting a lump sum down now.

Accelerated bi-weekly payments

Switching from monthly to accelerated bi-weekly payments at renewal costs almost nothing extra per month — the payment is simply half your monthly payment, made every two weeks. But because there are 26 bi-weekly periods in a year rather than 24 semi-monthly ones, you make the equivalent of one extra monthly payment every year. The interest savings over a 20-year amortization are substantial. This calculator shows the exact impact for your specific balance and rate.

Why does the interest picture matter at renewal?

Most people focus on the monthly payment change at renewal and miss the bigger picture. Seeing how much total interest you have already paid versus how much you still owe — and how much of your remaining payments will go toward interest — puts the renewal decision in proper context. A slightly higher rate or a few extra years of amortization can cost more than it appears from the monthly payment alone.
