How Much Down Payment Do You Need for a Car Loan With Bad Credit?

With bad credit, plan on 10% to 20% down, the range lenders most often look for (Canada Drives, Loans Canada). No law we found sets a minimum. On a $25,000 car at 14.99% APR over 72 months, each $1,000 down saves about $522 in interest and $21 a month (our calculation). Putting $5,000 down instead of nothing cuts the payment from $528.49 to $422.79 and saves $2,610.

A down payment also protects you from owing more than the car is worth, which the Financial Consumer Agency of Canada (FCAC) calls negative equity. This guide covers BC, Alberta and Ontario, where sales tax and trade-in rules change how far your down payment goes.

How much down payment do you need for a car loan with bad credit?

Most bad-credit lenders want to see 10% to 20% down, though some approve less. Loans Canada says lenders “generally ask for a down payment between 10% and 20% of the car price” and suggests 20%, especially on a new car (updated October 4, 2024). Canada Drives says 10% to 20% “strengthens your application and can lower your car loan rates”.

We found no minimum down payment in the federal or provincial consumer credit rules we reviewed for BC, Alberta and Ontario. Each lender sets its own, often based on your credit, income and the car. Loans Canada notes a lender will likely accept less than 20% on a used car, which has already taken its steepest depreciation.

How does a down payment change approval, your rate and the total cost?

A down payment always lowers the total cost because you pay interest on less, and it also helps approval. On a $25,000 car at 14.99% APR over 72 months, $5,000 down saves $2,610 in interest and $105.70 a month (our calculation). Approval improves because most lenders do not want to lend more than the car is worth (Loans Canada).

Whether a down payment lowers your rate is up to the lender; Canada Drives says only that it “can”. The interest saving above holds either way. If you finance Ontario’s 13% HST as well, the $0-down loan becomes $28,250. It costs $14,748 in interest over the same 72 months at 14.99% APR, against $12,138 with $5,000 down.

Or let the down payment buy a shorter term. The two examples below have almost the same monthly payment, but the second, with $5,000 down over 60 months, costs about $3,205 less in interest.

What is negative equity, and how does a down payment prevent it?

Negative equity is owing more on your car loan than the car is worth (FCAC, October 14, 2025). With $0 down on a $25,000 new car at 14.99% APR over 72 months, FCAC’s depreciation figures imply $3,470 of negative equity after one year. $5,000 down leaves you $974 ahead (our calculation, table below).

FCAC says a new car may be worth about 25% less after one year, then usually loses 15% to 25% a year over the next four years. FCAC’s own example, a $35,000 loan at 4% over 8 years, starts $3,700 underwater and reaches $8,520 after two years.

The table uses 25% after one year and FCAC’s 40% total drop after two years. A used car usually loses value more slowly, so treat this as a picture of the risk, not a forecast.

FCAC lists three risks when life changes:

• If you sell, you may need to borrow to cover the gap.
• If the car is written off, the insurance payout may not cover the loan.
• If you trade in, the unpaid amount is rolled into the next loan.

Does a trade-in count as a down payment, and what does it do to sales tax?

A trade-in counts toward your down payment only to the extent of its equity: what the dealer allows for it minus what you still owe on it. A car the dealer values at $8,000 with a $6,500 payoff gives you $1,500 of equity, not $8,000.

A trade-in also lowers your sales tax, which a cash down payment does not. If you do not charge GST/HST yourself, as most consumers don’t, the dealer charges it on the price minus the trade-in allowance (CRA; Excise Tax Act, s. 153(4)).

• Ontario: 13% HST on a dealer purchase (CRA).
• Alberta: 5% GST and no provincial sales tax (CRA).
• British Columbia: 5% GST plus PST on passenger vehicles from a dealer, starting at 7% under $55,000 and rising in tiers to 20% at $150,000 and over (PST Bulletin 116, revised April 2026). The PST tier is set on the price “before a deduction for a trade-in or down payment”.

In BC, the trade-in only reduces PST if the dealer accepts it as part of the same sale and shows its value on the sales agreement (PST Bulletin 116).

What do “$0 down” car loan ads leave out?

A “$0 down” offer means you borrow the full price, usually plus taxes and fees, so you pay interest on all of it and start with negative equity. On a $25,000 car at 14.99% APR over 72 months, $0 down costs $2,610 more in interest than $5,000 down, before any financed tax (our calculation). Canada Drives confirms such loans “do exist” with bad credit.

• Tax and fees get financed. In Ontario, 13% HST alone adds $3,250 to a $25,000 car.
• The term gets longer. A low $0-down payment often comes from 84 or 96 months. At 5% on $25,000, FCAC shows 84 months costing $4,681 in interest against $1,974 over 36.
• The payment hides the APR. In Ontario (O. Reg. 17/05, s. 61) and BC (BPCPA, s. 60(2)), an ad that states a payment or rate for fixed credit must also disclose the APR and the term.
• Add-ons ride along. Warranties and protection products folded in raise the amount financed.
• A deposit may not come back. FCAC warns a dealer may keep some or all of it if you decide not to buy.

Ads that promise approval for everyone deserve extra scepticism, and no lawful car loan can carry an APR above 35% (Criminal Code, s. 347). A dealer does not have to offer its cheapest rate (FCAC), so get a bank or credit union quote first.

How long does it take to save a car down payment?

Saving 10% of a $25,000 car, $2,500, takes $96.15 a week for 26 weeks or $48.08 a week for 52 weeks, and 20% takes twice that (our calculation).

That bar is the sales tax a trade-in saves and a private sale does not. Our guide to building an emergency fund in Canada covers the cushion to keep.

Frequently asked questions

What is the minimum down payment for a car loan in Canada?

There is no legal minimum that we found in BC, Alberta or Ontario. Each lender sets its own. With bad credit, lenders commonly look for 10% to 20% of the price, according to Canada Drives and Loans Canada, and some approve less.

Can I get a zero down car loan with bad credit in Canada?

Yes, some lenders offer zero-down loans to borrowers with bad credit, according to Canada Drives. But you pay interest on the full price plus any financed tax and fees, and you start with negative equity. On a $25,000 car at 14.99% APR over 72 months, $0 down costs $2,610 more in interest than $5,000 down.

Is it better to put 10% or 20% down on a car?

20% gives you more protection against negative equity and saves more interest, and Loans Canada suggests it as a target, especially on a new car. If 20% would empty your emergency savings, 10% plus a shorter term is usually the safer balance.

What should I do if I owe more than my car is worth?

FCAC’s advice is to avoid trading it in while you have negative equity, because the shortfall gets rolled into your next loan. If you can, keep the car and make extra payments. Consumer car loans in Ontario (CPA 2002, s. 76), BC (BPCPA, s. 74) and Alberta (Consumer Protection Act, s. 68) can be prepaid in full without penalty.
