Lease vs Finance vs Cash: Which Costs Less for a Car?
Loading article…
Lease vs finance vs pay cash: the cheapest option depends on how long you keep the car, how far you drive, and what your savings would earn elsewhere. To compare them fairly, this guide runs all three on the same fictional $40,000 vehicle bought in Ontario. Over four years, paying cash comes out cheapest in our base case; over eight years, buying and keeping the car beats two back-to-back leases by more than $19,000. For more borrowing guides, see our loans hub.
The vehicle, the rates, and the resale values below are assumptions chosen for the example, not offers from a dealer or a lender. The tax rate is real: Ontario's HST is 13% as of October 18, 2026, according to the Canada Revenue Agency (CRA). All figures were calculated for this guide.
How leasing, financing, and cash differ
When you pay cash, you own the car outright from day one. You pay the full price and the tax upfront, and you keep whatever the car is worth when you sell it. The hidden cost is the return your money could have earned in the meantime.
When you finance, a lender pays the dealer and you repay the loan with interest. You own the car, so its resale value belongs to you once the loan is paid. Car loan rates depend on the lender and your credit, and our loans hub gathers our borrowing guides.
When you lease, you pay for the car's expected loss of value during the lease, plus a finance charge, plus tax on each payment. At the end, you return the car or buy it at a price set in the contract, called the residual value. Leases also cap the kilometres you can drive and set a standard for the car's condition at return.
The example: one car, three options
Every scenario uses the same fictional vehicle and the same assumptions:
- Price before tax: $40,000, all dealer charges included
- Tax: 13% HST in Ontario, so $45,200 with tax
- Financing: 5.99% over 60 months, $0 down
- Lease: 48 months, 5.99% lease rate, $0 down, 20,000 km a year
- Value after 4 years: $20,800, which is also the lease residual
- Return on savings: 3% a year, for the opportunity cost of cash
These values are illustrations. Real residuals, lease rates, and kilometre allowances vary by model and by month, and only the dealer's contract shows yours.
Option 1: pay cash
You hand over $45,200 on day one. After 48 months, you sell the car for its $20,800 value. Your net cost is $24,400, which covers depreciation and tax.
That is not the whole cost. If the $45,200 had stayed in a savings account earning 3%, compounded monthly, it would have grown by $5,755.23 over four years. Adding that lost return brings the real cost of paying cash to $30,155.23. Our compound interest calculator shows how this growth adds up with your own numbers.
Option 2: finance the purchase
You borrow the full $45,200 at 5.99% over 60 months. The payment is $873.63 a month. After 48 months, you have paid $41,934.36, and $10,151.22 is still owing on the loan.
If you sell the car at that point for $20,800, you pay off the $10,151.22 balance and keep the rest. Your net cost is $31,285.58. That includes $6,885.58 in interest paid during the first four years.
Financing also has an opportunity cost, but a smaller one. Because you pay monthly instead of upfront, the money leaves your savings gradually. At 3%, that lost return comes to $2,560.79, for a total of $33,846.37.
Option 3: lease the car
A lease payment has two parts. The depreciation part is the price minus the residual, spread over the term: ($40,000 − $20,800) ÷ 48 = $400. The finance charge is (price + residual) × lease rate ÷ 24: ($40,000 + $20,800) × 0.0599 ÷ 24 = $151.75.
That gives $551.75 a month before tax. In Ontario, HST applies to each lease payment, so you pay $623.47 a month. Over 48 months, the lease costs $29,926.74, and you hand the car back with nothing to sell.
The opportunity cost is the smallest of the three, at $1,827.52, because the monthly outlay is lowest. The total comes to $31,754.26. If you want to keep the car at the end, the buyout is the $20,800 residual plus 13% HST, or $23,504.
Kilometres and wear can change everything
Leases set a kilometre allowance and charge for every kilometre above it. Suppose the contract charges $0.16 per extra kilometre (an assumption for this example) and you drive 30,000 km a year instead of 20,000. After four years you are 40,000 km over, which costs $6,400 plus HST, or $7,232.
That single charge raises the lease's total to $37,158.74 before opportunity cost, the highest of the three options. The federal Office of Consumer Affairs notes that prepaying extra kilometres upfront is usually cheaper than paying the penalty at return, and that unused kilometres earn no credit (Government of Canada).
Four-year comparison
The table below puts the three options side by side over 48 months. Net cost is what you paid minus what the car is worth at the end. The last column adds the return your money could have earned at 3%.
| Option | Paid over 48 months | Car value at month 48 | Net cost | Net cost with 3% opportunity cost |
|---|---|---|---|---|
| Pay cash | $45,200.00 | $20,800 | $24,400.00 | $30,155.23 |
| Finance (5.99%, 60 months) | $52,085.58 (payments plus payoff) | $20,800 | $31,285.58 | $33,846.37 |
| Lease (5.99%, 48 months, 20,000 km/year) | $29,926.74 | Car returned | $29,926.74 | $31,754.26 |
| Lease, driving 30,000 km/year | $37,158.74 | Car returned | $37,158.74 | $38,986.26 |
What happens over eight years
The four-year view favours short ownership. Most people keep their cars longer: the Office of Consumer Affairs points out that average ownership in Canada is about eight years, roughly two lease terms. Here is the same car kept for eight years, assuming it is worth $12,000 at the end.
- Pay cash and keep it: $45,200 paid, net cost $33,200
- Finance over 60 months and keep it: $52,417.80 paid, net cost $40,417.80
- Two 48-month leases at the same terms: $59,853.48 paid, net cost $59,853.48
Buying and keeping the car beats two consecutive leases by $19,435.68 when financed, and by $26,653.48 when paid in cash. These figures exclude maintenance and repairs, which a long-term owner pays once the warranty ends. Even with $5,000 of repairs in years five to eight, ownership stays ahead in this example.
When each option wins
No option wins every time. The result depends on a few conditions you can check before you sign.
When paying cash wins
Paying cash wins when the cash would otherwise earn less than the loan rate after tax. In our example, the car loan costs 5.99% while savings earn 3%, so avoiding the loan saves money. Keep an emergency fund aside first; our guide to the best savings accounts shows where that reserve can sit.
When financing wins
Financing wins when the loan rate is lower than what your money earns. With a 0% manufacturer promotion over 60 months, the payment drops to $753.33 and there is no interest. In our example, the net cost including opportunity cost falls to $26,608.18, which is $3,547.05 less than paying cash.
When leasing wins
Leasing wins when you replace your car every three or four years, drive less than the allowance, and return the car in good condition. It also helps when the manufacturer subsidizes the lease rate or sets a generous residual. Our fictional lease beat financing over four years because HST applies only to the payments, not to the full price.
Conclusion
Over four years, paying cash cost the least in our example once lost interest was counted, with leasing second and financing third. Over eight years, buying and keeping the car was far cheaper than leasing twice. If you drive more than the lease allowance, leasing becomes the most expensive option. Run the numbers with the real residual, lease rate, and loan rate from your dealer before you choose.

Frequently asked questions about leasing vs financing a car
Is it cheaper to lease or finance a car in Canada?
It depends on how long you keep the car. In our fictional Ontario example, a 48-month lease cost $29,926.74 against $31,285.58 for financing over the same four years. Over eight years, however, financing and keeping the car cost $40,417.80, while two leases cost $59,853.48. If you keep cars a long time, buying usually wins. Our loans hub covers the financing side in more detail.
Is it better to pay cash for a car or finance it?
Compare the loan rate with what your savings earn. If your loan costs 5.99% and your savings earn 3%, paying cash saves money, as it did in our example. If the dealer offers 0% financing, keep your cash invested and take the loan. Make sure you still have an emergency fund afterward, and see our list of the best savings accounts for where to keep it.
What is a residual value in a car lease?
The residual value is the price, set in the lease contract, at which you can buy the car at the end of the term. A higher residual means the car is expected to lose less value, which lowers your monthly payment. In our example, a $20,800 residual on a $40,000 car meant $400 a month in depreciation over 48 months. The lessor, usually the manufacturer's finance company, sets this number. Use our compound interest calculator to compare a buyout with keeping your cash invested.
What happens if I drive more kilometres than my lease allows?
You pay a charge for every kilometre over the allowance when you return the car. In our example, driving 40,000 km too many at $0.16 per kilometre cost $7,232 with HST. Federal consumer guidance notes that buying extra kilometres upfront is usually cheaper, and that unused kilometres earn no refund. Estimate your driving honestly before you sign, and factor in your car insurance costs, which also depend on how much you drive.
Can I end a car lease early?
Usually only at a cost. The Government of Canada's leasing tips state that breaking a lease can be difficult and usually means paying penalties. Options include a buyout at the contract price or a lease transfer, if your contract allows one. If you think your needs may change within the term, a loan is more flexible, since you can sell the car at any time. Our credit score ranges guide explains how your credit affects both lease and loan approvals.
Do you pay less tax when you lease a car?
You pay tax on each lease payment instead of the full price, so you pay less tax during the lease. In our Ontario example, the HST on the lease came to $3,442.90 over four years, against $5,200 upfront on a purchase. Over a lifetime of cars, however, leasing means paying tax on payments continuously, and a lessee does not get the trade-in tax reduction on the next purchase. Our loans hub has more on financing a purchase.
