How To Use This Explorer

Enter your loan amount, rate, and term, then add an optional extra monthly payment.

The chart shows principal and interest stacked over the full life of the loan, so you can see exactly how the mix shifts year by year, and how much faster an extra payment actually gets you to zero.

Your Inputs

Loan Amount $400,000

Annual Interest Rate 5.5%

Amortization Period (Years) 25

Extra Monthly Payment $300

Uses standard monthly compounding and a fixed rate for the full amortization period, matching how most Canadian instalment loans and simplified mortgage models are structured.

What The Extra Payment Actually Does

Interest Saved With Extra Payments

Monthly Payment

Paid Off This Many Years Sooner

Remaining Balance: Standard Vs. With Extra Payments

This tool assumes a fixed rate held constant for the entire amortization period, actual variable-rate loans and mortgages renewing at different rates over time will produce different results.
