Loan Calculator (Canada)
This loan calculator for Canada estimates the monthly payment, total interest and total cost of any fixed-rate loan from the amount, rate and term.

What it does
The Canada Loan Calculator works out the fixed monthly payment on any installment loan, plus the total interest and the total cost over the life of the loan, using standard amortization.
Data sources & parameters
This calculator uses standard financial formulas and runs entirely in your browser. It needs no external rate data — your result is computed only from the values you enter above.
We always strive to use the latest data for every variable so our results and reports are as accurate as possible. Even so, errors are possible — you should not rely on this tool or its report alone, and we accept no liability for any decision made based on it.
The formula
monthly = amount × i ÷ (1 − (1 + i)^−n), where i = annual rate ÷ 12 and n = years × 12; total cost = monthly × n; total interest = total cost − amount
How it works
It converts your annual interest rate to a monthly rate, spreads the loan across the number of months in your term, and solves for the level payment that clears the balance by the final month. It then multiplies that payment by the number of months to find the total cost and subtracts the amount borrowed to isolate the interest.
Where it is used
- Comparing loan offers with different rates and terms
- Checking whether a monthly payment fits your budget
- Seeing the true interest cost of borrowing in Canada
Worked example
Borrowing CA$20,000.00 at 6% over 5 years means a monthly payment of …, with … in interest and … paid in total.
Before you borrow, you need the monthly payment, the total interest and the total cost. A personal loan, a car loan, a renovation loan or a line of credit converted to a fixed schedule all work the same way: a fixed amount, an annual rate, and equal monthly payments over a set number of years. Enter the amount, rate and term, and the calculator returns the payment and the full cost.
How the monthly payment is worked out
The annual rate is divided by twelve and the years multiplied by twelve. The calculator then finds the single payment that, repeated every month, brings the balance to zero in the final month, using the standard annuity formula: payment = loan × monthly rate / (1 − (1 + monthly rate)^−months). Mainstream lenders use the same arithmetic, so the result should track a real quote closely.
Where each payment goes
The payment stays the same, but early payments are mostly interest because the balance is large; later ones are mostly principal. That is why an extra payment in the first year saves more than the same amount near the end.
A worked example
$20,000 at 6% over five years: the monthly rate is 0.5% over 60 months, and the payment is about $386.66. You repay about $23,199, of which about $3,199 is interest. At 4% on the same amount and term, the payment falls to about $368 and interest to about $2,100, saving about $1,100. A seven-year term at 6% would lower the payment further but add interest over the extra two years.
Choosing a term that fits
A longer term lowers the payment but means more interest in total; a shorter term does the reverse. Try three, five and seven years with the same amount and rate and watch the payment fall as total interest climbs. Choose a payment your budget can carry against the total you are willing to pay.
Comparing offers on the true cost
Two loans with similar monthly payments can differ a lot: a lower rate with a longer term can cost far more in interest. Compare the monthly payment, total interest and total cost side by side. A loan that costs a little more each month but ends years earlier is often cheaper overall.
Loan rules and conventions across Canada
Most everyday loans compound monthly, which this calculator assumes. Fixed-rate mortgages are the exception: by law they are compounded semi-annually, so use a mortgage calculator for them. Provincial cost-of-credit laws govern how the annual rate, total cost of credit and fees are disclosed, and provinces regulate high-cost products such as payday loans separately.
Common mistakes and planning tips
- Judging a loan by its monthly payment alone instead of the total cost.
- Assuming a longer term is cheaper.
- Overlooking fees and insurance add-ons, which the calculator does not include.
- Treating a promotional 0% offer as normal; confirm the rate that applies afterwards.
Assumptions and limitations
This is a planning estimate, not a quote. It assumes a fixed rate for the whole term, equal monthly payments, no missed or extra payments, monthly compounding, and no fees beyond the rate. It does not model variable rates, origination fees, insurance or early payoff. Confirm the rate, fees and total cost of credit with the lender in writing before borrowing.
