Depreciation/Depreciation period 30 years vs 25 years in Quebec: which to choose for your mortgage loan

29 May 2026


When purchasing a property in Quebec, choosing the loan amortization period is crucial. The most common options are 25 and 30 years, each with specific advantages and disadvantages. This detailed article will help you understand these differences and determine the best option based on your financial situation.

Understanding mortgage amortization

Amortization refers to the period required to fully repay your mortgage. A longer amortization reduces your monthly payments but increases the total interest cost over the life of the loan. Conversely, a shorter period results in higher monthly payments but lowers the total interest cost.

Numerical comparison: 25 years vs 30 years

To illustrate the impact of these two options, consider a $400,000 mortgage at a 5% interest rate.

Advantages and disadvantages of each option

25-year amortization

  • Advantages:Less interest paid over the life of the loan.
  • Faster buildup of equity in the property.
  • Faster release from mortgage debt.
  • Disadvantages:Higher monthly payments, which may limit financial flexibility.

30-year amortization

  • Advantages:Lower monthly payments, easing budget management.
  • May allow access to a more expensive property with affordable monthly payments.
  • Disadvantages:Higher total interest cost over the life of the loan.
  • Slower buildup of equity in the property.

Financial considerations and impact on monthly payments

Choosing between 25 and 30 years depends on your personal financial situation. If you prefer lower monthly payments for greater budget flexibility, a 30-year amortization may be advantageous. However, if your goal is to reduce the total interest cost and accumulate equity more quickly, a 25-year amortization is preferable.

Concrete examples for Quebec

Let's take the example of a first-time homebuyer in Quebec looking to purchase a home valued at $350,000 with a 20% down payment. The loan amount would thus be $280,000. At an interest rate of 4.74%, the details would be as follows:

Conclusion

The choice between a 25- or 30-year amortization depends on your financial priorities. If you seek lower monthly payments for greater budget flexibility, a 30-year amortization may be appropriate. However, if your goal is to reduce the total interest cost and accumulate equity faster, a 25-year amortization is recommended. It is essential to evaluate your personal financial situation and long-term goals before making a decision.
