How This Works
Profit margin tells you what percentage of the sale price you actually keep as profit. It's the quickest way to evaluate whether a deal is worth doing — and whether your pricing is competitive enough to move the vehicle within a healthy time frame.
The Formulas
Gross Profit = Asking Price − Purchase Price − Recon Cost
Gross Margin = (Gross Profit ÷ Asking Price) × 100
ROI = (Gross Profit ÷ Total Invested) × 100
Annualised ROI = ROI × (365 ÷ Days to Sell)
Margin vs. Markup — They're Not the Same
A common source of confusion: markup is profit as a percentage of cost, while margin is profit as a percentage of selling price. A vehicle you bought for $28,000 and sell for $34,900 has a 24.6% markup but only a 15.5% margin. Lenders, accountants, and industry benchmarks almost always reference margin — so that's what this calculator uses.
A Real-World Example
You purchase a 2022 Honda CR-V for $28,000 CAD, spend $1,500 on reconditioning, and list it at $34,900. Your total investment is $29,500.
Gross Profit = $34,900 − $29,500 = $5,400
Gross Margin = $5,400 ÷ $34,900 = 15.47%
ROI = $5,400 ÷ $29,500 = 18.31%
Annualised ROI (sold in 38 days) = 18.31% × (365 ÷ 38) = 175.83%
The annualised ROI shows why turn time matters so much. The same deal that looks modest at 18% ROI becomes extraordinary when you can repeat it every 38 days. Conversely, if the vehicle sits for 90 days, your annualised return drops to 74% — and that's before floor plan carrying costs eat into the gross.
What's a Good Margin?
For Canadian used vehicle retail, front-end gross margins typically range from 8% to 12%. Dealerships that consistently exceed 12% usually have strong appraisal processes, fast reconditioning pipelines, and data-driven pricing strategies. Margins below 6% often signal that the vehicle was overpriced at acquisition or sat too long.
Why This Matters
Gut-feel pricing is the most expensive habit in the used car business. When you don't know your true margin before listing a vehicle, you're gambling — and the house usually wins on the back end through carrying costs, price reductions, and wholesale losses.
High-performing dealers calculate margin before they set the asking price, not after the deal closes. They know their target gross, their maximum days on lot, and the point at which wholesaling makes more financial sense than waiting for a retail buyer.
Vinly gives you margin visibility at the point of appraisal — so you can make confident buy-or-pass decisions backed by live market data, not guesswork.
Know your margin before you price
Vinly calculates profit margins, tracks market position, and flags deals that aren't working — so you can act before margins erode.
