Amortization schedule for a $100,000 mortgage

What is amortization?

Your amortization period is the total number of years you have to pay off your mortgage.

When you take out a mortgage, you agree to pay the principal and interest over the life of the loan. Your interest rate is applied to your balance, and as you pay down your balance, the amount you pay in interest changes.

This means that at the beginning of your loan, a big percentage of your payment is applied to interest. With each subsequent payment, you pay more toward your balance.

Below, you can estimate your monthly mortgage repayments on a $100,000 mortgage at a 3% fixed interest rate with our amortization schedule over 10- and 25- years.

• 10-year mortgage
• 25-year mortgage

Will I need a down payment for my new home?

Yes, you’ll need to provide a down payment of 5-20% for your home. Providing a down payment of less than 20% requires that you insure your mortgage with CMHC insurance. This is an extra expense on top of any fees and interest you’ll pay. If you have an insured mortgage, the longest amortization period you can choose is 25- years.

Additional fees to consider

Buying a home is an investment. Along with the down payment and mortgage insurance (if applicable), you’ll need to pay a range of closing costs, fees and taxes. These vary between lenders and property types, but they can add up to thousands of dollars. Be sure to factor these into your budget. If you’re a first-time home buyer, you may be able to receive tax credits or rebates.

Costs may include:

Bottom line
