How it's calculated
- Each payment first covers the interest built up since the last one. What is left reduces the balance, so early payments are mostly interest.
- Fixed-rate Canadian mortgages compound twice a year. Variable-rate mortgages and most loans compound monthly. Pick the one in your contract.
- Extra payments and the yearly lump sum go straight to principal. The lump sum is paid with the last payment of each year of the loan.
- The final payment clears whatever is left, so the schedule ends at exactly $0.00.
- Accelerated bi-weekly and weekly payments are the monthly payment divided by two or four. That adds up to one extra monthly payment a year.
Frequently asked questions
What is an amortization schedule?
A table of every payment on a loan, split into interest and principal, with the balance left after each one. Early payments are mostly interest and later ones are mostly principal.
How does compounding change my payment?
Canadian fixed-rate mortgages compound twice a year, which gives a slightly lower payment than monthly compounding at the same rate. Choose monthly for variable-rate mortgages and most other loans.
How much do extra payments save?
Enter an extra amount for each payment, a yearly lump sum, or both. The results show the interest you save and how much sooner the loan ends. Check your lender's prepayment limits before you plan around them.
What is the difference between amortization and term?
Amortization is how long the whole loan would take to pay off. The term is how long your current rate and contract last, often five years. This schedule runs for the full amortization.
Why is my last payment different?
Payments are rounded to the cent, and extra payments end the loan between regular dates. The final payment clears what is left, so the balance finishes at $0.00.
