Budget Beavers The Real Cost of Your Car
Depreciation, insurance, fuel, maintenance — the costs dealers never show you.
Your Car
First-year depreciation is typically 20–25%. Subsequent years average 15% (Canadian Black Book 2025 averages). EVs lose more: 57% over 5 years.

Loan Balance vs Car Value — The Underwater Chart
When the red loan balance line is above the purple car value line, you are "underwater" — you owe more than the car is worth. This is the trade-in trap.
The math behind your result
Every number on this page is calculated in your browser from the inputs you provided. Car loans use APR/12 monthly compounding — not the semi-annual compounding of Canadian mortgages. Depreciation uses a two-phase declining-balance model: 22% in Year 1 (first-year hit), 15%/yr thereafter. Expand below to see the exact formulas.
▶ How is this calculated?
1. Car loan payment (APR/12 monthly compounding)
payment = P × r × (1+r)^n / ((1+r)^n - 1) where: P = loanPrincipal = purchasePrice - downPayment r = loanRate / 12 (APR/12 — monthly compounding) n = loanTermMonths NOTE: Car loans are personal credit. APR/12 is correct. The Interest Act semi-annual rule applies ONLY to residential mortgages. Example ($32,000 at 6.9%, 72 months): r = 0.069 / 12 = 0.00575 n = 72 PMT = 32000 × 0.00575 × (1.00575)^72 / ((1.00575)^72 - 1) ≈ $544/mo
2. Depreciation model (two-phase declining balance)
value(0) = purchasePrice value(1) = purchasePrice × (1 - firstYearRate) ← e.g. 22% value(y) = value(1) × (1 - annualRate)^(y-1) ← e.g. 15%/yr for y ≥ 2 Monthly depreciation shown = value(0) × firstYearRate / 12 Source: Canadian Black Book 2025 averages. EVs average 57.2% over 5 years; use the Advanced toggle to adjust.
3. True monthly cost
trueMonthlyCost = loanPayment
+ monthlyDepreciation (firstYearLoss / 12)
+ monthlyInsurance
+ monthlyFuel
+ monthlyMaintenance (annualMaintenance / 12)
+ monthlyParking (default $100)
monthlyGap = trueMonthlyCost - loanPayment ← the viral number 4. Gap invested (future value of monthly contributions)
FV = gap × ((1 + 0.07/12)^n - 1) / (0.07/12) where n = number of months (60 for 5yr, 120 for 10yr) This is the ordinary annuity FV formula — the amount you'd have if you invested the gap each month in a diversified equity fund at 7%/yr (historical real return on global equities, per MSCI World since 1970).
About This Calculator: The Real Cost of Your Car
The monthly payment trap
When Canadians shop for a car, one number dominates the conversation: the monthly payment. Dealers know this, and they structure the entire sales process around it. The "four-square" technique — where a salesperson focuses your attention on the payment box while quietly adjusting the purchase price, loan term, and trade-in allowance — is specifically designed to prevent you from thinking about total cost. 52% of Canadians report higher anxiety buying a car than buying a home, according to a J.D. Power survey — in part because the car transaction is deliberately opaque.
The payment you agree to in the showroom typically covers only one thing: the loan. What it does not cover is everything else that will show up in your bank account every month. Insurance, which averages $200/mo in Ontario (and $450–$700/mo for newcomers or young drivers). Fuel, which runs $186–$220/mo for a mid-size SUV at current Canadian pump prices. Maintenance — oil changes, tires, brakes — that dealers never mention until you're in the service bay facing a $600 quote. Parking, which in downtown Toronto alone runs $200–$300/mo. And depreciation: the quiet, relentless loss in your car's value that costs you $730/mo in the first year on a $40,000 vehicle even when it sits in your driveway overnight.
Depreciation: the invisible cost
The most important number in this calculator is the one dealers never put on a sticker: depreciation. The average new car in Canada loses 20–25% of its value in the first year, and 41.8% over five years (Canadian Black Book 2025 averages). A $48,000 car — the 2025 Canadian average — loses $9,600–$14,400 in the first 12 months. That is $800–$1,200 per month, every month, whether you drive it or not.
The worst offenders are electric vehicles: EVs depreciate 57.2% on average over five years (Canadian Black Book 2025). A Nissan LEAF loses 63.1% — a $40,000 LEAF is worth roughly $14,760 in five years. Buyers who purchased EVs in 2021–2022 are now discovering their cars are worth under $22,000 while they still owe $30,000 on the loan. This is the trap this calculator is designed to reveal before you sign, not after.
Why dealers never show you the real number
It's not a coincidence that no car dealership in Canada shows you a "total cost of ownership" disclosure before you sign. The business model depends on you thinking about the monthly payment, not the five-year total. At the F&I (Finance and Insurance) desk — the second room, after you've agreed to a price — the focus shifts to add-ons: extended warranties, GAP insurance, paint sealant, nitrogen in tires. Each is presented as protecting your investment. None of them are priced relative to the true total cost you're already committing to.
The average Canadian car buyer spends less time reviewing a car loan contract than reading a restaurant menu. The transaction is designed to be completed quickly, under mild pressure, with information asymmetry strongly in the dealer's favour. That is what this calculator exists to fix.
The consolation car phenomenon
Canadian bankruptcy trustees have documented a pattern among young adults aged 25–35: locked out of the housing market by prices that require a household income of $140,000+ to qualify, they redirect their aspiration toward a car. "If I can't own a house, at least I can own a nice car." This is not a financial decision. It is an emotional response to systemic exclusion from homeownership.
The outcome is predictable: nearly one in three Canadians who financed since 2022 is underwater — they owe more than the car is worth. The average monthly payment for someone who rolled negative equity from a prior loan into a new one is $916/month before insurance, fuel, or parking. Add the full true cost and you are looking at $1,600–$2,000/month for a depreciating asset. A $40,000 car at $1,900/month true cost over 20 years is not just transportation. It is the mechanism by which wealth does not accumulate.
The work-hours framing — how many hours you work each month just to cover your car — is the number that changes minds. At $30/hour, a $1,900/month car costs you 63 hours of your life every month. That is the equivalent of nearly two full work weeks, every single month, forever.
The 84-month loan and the underwater years
About 65% of Canadian car buyers now finance over 72–96 months to lower their monthly payment. This creates what finance researchers call the "underwater window": the period during which your outstanding loan balance exceeds the car's market value. At 6.9% over 84 months, you are typically underwater for the first 3–4 years of the loan. If you need to sell, trade in, or total the car during this period, you will owe more than you recover — and that shortfall often gets rolled into the next loan, compounding the trap.
Financial advisors uniformly cap their car loan recommendation at 60 months. The Loan Balance vs Car Value chart on this page shows you exactly when your equity turns positive.
Not financial advice. This calculator provides estimates for educational purposes. Depreciation varies significantly by make, model, and mileage. Insurance rates vary by province, age, driving record, and coverage level. Fuel costs depend on driving habits and local pump prices. The 7% investment return assumption is a long-run historical average and is not guaranteed. All calculations happen in your browser — no input data is sent to any server.
