Financing guide
What a loan actually costs
Two loans with the same advertised rate can cost very different amounts. The rate is one of at least five numbers that determine what you repay, and it is the one most designed to be compared. This guide covers the others, and how to put them on one footing so the comparison is honest.
The five numbers that set the cost
**The interest rate**, and whether it is fixed or variable. On a fixed rate the payment is known; on a variable rate it is not, and in Canada the Bank of Canada policy rate is the reference the market prices against.
**The term**, because interest accrues for as long as the balance exists. Doubling the term roughly doubles the interest even at a lower payment.
**The origination fee**, which is usually deducted from the amount you receive, so a 5% fee on a $10,000 loan leaves you $9,500 and a $10,000 debt.
**Insurance and add-ons**, which are frequently presented as optional and are priced per dollar borrowed rather than as a rate.
**Prepayment terms**, which decide whether you can escape the schedule cheaply by overpaying.
- Ask for the amount you receive and the amount you repay, both in writing.
- Ask whether the origination fee is deducted from the principal.
- Ask whether extra payments reduce principal immediately.
- Ask what the rate becomes if a promotional period ends.
Put everything on the same footing
The only fair comparison between two loans is the total amount repaid for the same borrowed amount over the same period. Compute that, and the marketing collapses: a lower rate with a large fee frequently loses to a slightly higher rate with no fee.
The loan payment calculator on this site returns the monthly payment, total interest and total repaid, and shows the balance and cumulative interest at each year end — which is where a long term reveals itself.

Read a published price index for what it is
Costs move, and official price indexes are how you check what has actually changed rather than what someone claims. The U.S. series below is published monthly by the Bureau of Labor Statistics and is the same data used to compute official inflation.
The affordability question comes first
Before comparing loans, establish what payment you can carry. The affordability calculator applies a debt-to-income limit to gross monthly income, subtracts existing debt payments, and converts the remainder into a loan amount. Lenders apply their own limits and weigh credit history, employment and collateral; treat the result as a ceiling to test quotes against, not an approval.
The comparison that ends the argument
For each offer, compute the total amount repayable for the same borrowed amount over the same number of months. That single figure includes the rate, the term and every fee that is financed, and it is the number the marketing avoids. If one offer cannot produce it, use the payment multiplied by the number of payments and add any fee paid upfront.
Where the amounts borrowed differ because a fee is deducted, normalise by comparing total repayable per dollar actually received. That is the honest unit price of the borrowing, and it is the number to rank offers by.
A checklist to run on every offer
Take each offer and fill in the same eight fields, then compare the last one. Amount borrowed; amount actually received after fees; annual rate and whether it is fixed or variable; term in months; monthly payment; total amount repayable; whether extra payments reduce principal immediately; and any prepayment penalty. The field that decides the comparison is the sixth, because it is the only one that includes every fee and every month of interest.
Where an offer cannot answer one of the eight, treat the offer as incomplete rather than assume the missing item is free.
Why monthly payment is the wrong headline
A monthly payment can be lowered by stretching a term, which costs money, or by adding a balloon payment at the end, which moves the cost rather than removing it. A balloon structure makes the payment look small for the whole term and then requires a lump sum or a refinance at whatever rate is available at the time. If a payment looks materially lower than other offers for the same amount, ask what happens at the end of the term before you ask anything else.
Insurance, add-ons and what is genuinely optional
Payment protection, credit insurance and extended warranties are commonly offered alongside a loan and priced per dollar borrowed, which makes them look small and cost a great deal relative to the cover. They are frequently optional, and in several jurisdictions they must be presented as optional — ask directly whether declining changes the rate or the approval, and get the answer in writing.
If you need the cover, buy it separately where that is possible, so you can see its actual price rather than a per-dollar-of-balance figure buried in a payment schedule.
What to do if the loan turns out worse than described
In the United States, mortgage disclosures carry a three-day right of rescission on certain refinances and a right to a corrected Closing Disclosure before consummation; consumer loans generally do not, so the written disclosure you received before signing is your record. In Canada, federally regulated lenders must disclose the cost of borrowing and the annual percentage rate, and provincial consumer protection legislation sets cooling-off rules for some loan types.
Keep the disclosure, the signed agreement and the payment schedule. If the loan does not match what you were told, the first step is a written complaint to the lender, and the second is the relevant regulator — the CFPB in the United States or the Financial Consumer Agency of Canada federally.
