How do extra payments work on a loan?

**Extra payments on a loan go directly to reducing your principal balance, which means every dollar you pay above your scheduled payment stops accruing interest immediately.** Because loan interest is calculated on the outstanding principal each month, reducing the principal early creates a compounding savings effect that grows over the remaining life of the loan.

Consider a $25,000 personal loan at 7.5% over 5 years. Your scheduled monthly payment is approximately $501. In Month 1, about $156 goes to interest and $345 goes to principal. If you pay an extra $100 that month, the full $100 goes to principal, reducing next month's interest charge by $0.63. That $0.63 saving recurs every month for the rest of the loan, and the savings compound as the principal decreases faster.

There are two main strategies for accelerating loan payoff: regular extra monthly payments (a consistent additional amount each month) and one-time lump sum payments (a single larger payment applied to principal). This calculator lets you combine both to see the maximum impact on your payoff date and total interest cost.

Unlike Canadian mortgages which use semi-annual compounding under the [Interest Act (RSC, 1985, c. I-15)](https://laws-lois.justice.gc.ca/eng/acts/i-15/FullText.html), personal loans, car loans, and student loans in Canada use standard monthly compounding. This means your annual rate is simply divided by 12 to get the monthly rate.

Lump sum vs regular extra payments: which saves more?

**A lump sum payment saves more interest per dollar because the full amount reduces principal immediately, eliminating interest on that amount for all remaining months.** Spreading the same total as extra monthly payments saves less because each increment only stops interest from the month it is applied forward.

Example: On a $25,000 loan at 7.5% with 5 years remaining, a $3,000 one-time lump sum in Month 1 saves approximately $1,300 in total interest. Spreading the same $3,000 as $50/month extra over 5 years saves approximately $900 in interest. The lump sum wins by about $400 because the full $3,000 stops accruing interest 60 months earlier than the last $50 monthly payment.

However, most people do not have a large lump sum available. The practical recommendation is to do both when possible: set up a consistent extra monthly payment (even $50 to $100 makes a meaningful difference), and apply windfalls like tax refunds, bonuses, or gift money as lump sums whenever they arrive.

The timing of your lump sum matters significantly. Paying $3,000 extra in Year 1 of a 5-year loan saves roughly three times the interest of the same payment in Year 4, because there are more remaining months for the reduced principal to generate savings.

Snowball vs avalanche: which debt payoff strategy is better?

**If you have multiple debts, the avalanche method (paying off the highest interest rate first) saves the most money, while the snowball method (paying off the smallest balance first) provides faster psychological wins that help many people stay motivated.**

The avalanche method works by directing all extra payments to the debt with the highest interest rate while making minimum payments on everything else. Once the highest-rate debt is eliminated, you redirect that entire payment to the next highest rate. Mathematically, this always minimizes total interest paid.

The snowball method targets the smallest balance first, regardless of interest rate. The advantage is that you eliminate individual debts faster, which creates a sense of progress and momentum. Research from the Harvard Business Review found that people who focus on small wins are more likely to follow through with debt repayment than those who optimize purely for interest savings.

For most Canadians with typical consumer debt (credit cards at 20%, personal loans at 7-12%, car loans at 5-8%, student loans at variable prime+), the avalanche method clearly favours targeting credit card debt first. The snowball method only produces a noticeably different result when all your debts have similar interest rates but different balances.

• ✓Avalanche: pay off highest interest rate first, always minimizes total interest paid
• ✓Snowball: pay off smallest balance first, creates psychological momentum with quick wins
• ✓Hybrid approach: target debts above 10% with avalanche, use snowball for debts under 10%
• ✓Both methods require making minimum payments on all other debts while focusing extra payments on one target
• ✓The best method is the one you will actually follow through on consistently

Prepayment penalties: what Canadian borrowers need to know

**Most personal loans and car loans in Canada have no prepayment penalty, meaning you can pay extra or pay off the full balance at any time without cost.** However, some fixed-rate loans and closed credit products may include an early repayment charge, so always check your loan agreement.

Under the [Bank Act](https://laws-lois.justice.gc.ca/eng/acts/b-1.01/) and provincial consumer protection legislation, Canadian lenders must disclose prepayment penalties in your loan agreement. The [Financial Consumer Agency of Canada (FCAC)](https://www.canada.ca/en/financial-consumer-agency/services/loans/personal-loans.html) requires clear disclosure of any fees associated with early repayment.

Payday loans and high-interest subprime loans sometimes use structures where interest is pre-calculated for the full term (sometimes called the Rule of 78 or pre-computed interest). In these cases, paying early does not save as much interest as you would expect. The [Criminal Code of Canada (Section 347)](https://laws-lois.justice.gc.ca/eng/acts/c-46/page-73.html) caps the effective annual rate at 60%, and any loan charging above that is criminal.

Before making a large extra payment, call your lender and confirm: (1) Is there a prepayment penalty? (2) Will extra payments be applied to principal or to future payments? (3) Is there a maximum extra payment amount per year? Some lenders apply extra payments to advance your due date rather than reduce your principal, which does not save interest.

Should you pay off your loan early or invest the money?

**If your loan interest rate is higher than your expected after-tax investment return, paying off the loan is the better financial decision.** Paying off a 7.5% loan gives you a guaranteed, risk-free 7.5% return on every extra dollar. To beat that by investing, you need returns above 7.5% after tax, which is difficult to achieve consistently.

The break-even calculation is straightforward: compare your loan rate to your expected investment return multiplied by (1 minus your marginal tax rate). For example, if your marginal rate is 30% and you expect 8% investment returns, your after-tax return is 8% x 0.70 = 5.6%. If your loan is at 7.5%, paying off the loan wins.

There are exceptions where investing makes sense even with a higher loan rate. If your employer offers RRSP matching, the match provides an immediate 50% to 100% return on contribution, which beats any loan rate. TFSA contributions grow tax-free, and if you have unused contribution room, the long-term tax advantage can justify investing before aggressively paying down a moderate-rate loan.

A balanced approach works for many Canadians: maximize employer RRSP matching first, maintain a 3-month emergency fund, then split extra money between loan prepayment and TFSA contributions. This reduces debt risk while building long-term wealth. If your loan rate is above 10%, prioritize full repayment before any non-matched investing.

Worked example: how much can you save?

**Scenario:** You have a $25,000 personal loan at 7.5% with a monthly payment of $501 (5-year term). You want to compare three extra payment strategies.

**Strategy 1: Extra $100/month.** Adding $100 per month to your payment saves approximately $2,800 in total interest and pays off the loan 17 months early. Your total interest drops from approximately $5,050 to approximately $2,250.

**Strategy 2: $5,000 one-time lump sum.** Applying $5,000 immediately to principal saves approximately $2,400 in total interest and shortens the loan by about 11 months. The lump sum is slightly less efficient per dollar than sustained monthly extras because the monthly method applies principal reductions every month for the full remaining term.

**Strategy 3: Both combined.** Extra $100/month plus $5,000 lump sum saves approximately $3,800 in interest and pays off the loan nearly 2 years early. Your 5-year loan becomes approximately a 3-year loan.

**Key takeaway:** Even modest extra payments compound into substantial savings. A $100/month increase is about $3.30/day, yet it saves nearly $2,800 in interest. Use the calculator above to model your specific loan.
