Three straight-up calculators for Canadian buyers — no dealer math, no bi-weekly tricks. Check if you can afford it, see what a payment schedule actually costs, and find out whether trading in beats selling it yourself.
There are 26 bi-weekly payments in a year, not 24. That quote is really $563 a month — $520 more out of your pocket every year than it sounds like.
Enter the car and your income. You get the real monthly payment, the full cost of owning it (insurance, fuel, maintenance included), and a straight verdict against the rules lenders and advisors actually use.
Same loan, three ways to pay it. Bi-weekly payments look smaller because there are 26 of them a year — this shows the true monthly cost, the total interest, and how much faster an accelerated bi-weekly plan kills the loan.
Got quoted a bi-weekly number? Put it in — here's what it really is per month.
Private sales usually fetch more — but in Ontario a trade-in cuts the tax on your next car, because you only pay HST on the difference. This does the full math, including what selling it yourself actually costs you.
Payment ≤ 15% of gross income and all-in car costs ≤ 20% is the classic ceiling. The stricter 20/4/10 check: at least 20% down, term no longer than 4 years, payment no more than 10% of take-home. Passing one and failing the other means “doable, but tight.”
Standard amortization: payment = P × r(1+r)ⁿ ÷ ((1+r)ⁿ − 1), where r is the rate per payment period. Accelerated bi-weekly pays half a monthly payment every two weeks — 26 half-payments a year equals 13 monthly payments, so one extra payment a year goes straight to principal.
Trading in reduces the taxable amount of your next car: tax saved = trade value × tax rate. A $12,000 trade at 13% HST is worth $13,560 in real terms — a private sale has to clear that bar, after selling costs, to actually win.
