In car retailing, sticker price doesn’t always tell the full story. Between vehicle prep, advertising, finance fees, warranties, and overheads, the margin that lands in your pocket can vary greatly. Use our Motor Trade Profit Per Vehicle Calculator to unmask your true profit and identify cost levers you can tighten.

How it works

1. Enter your sale price and purchase cost of the vehicle.

2. Add in preparation, advertising, finance/commission, warranty, and allocated overheads.

3. The calculator gives:
    • Gross profit (sale minus purchase)
    • Total costs (all add-on expenses)
    • Net profit after all costs
    • Margin on cost (% over purchase)
    • Return on sale price (% over sale)

Why this is critical

• Too many dealers focus solely on gross margin, ignoring add-ons that erode profits.

• Transparent cost breakdowns expose hidden expense lines.

• You can test “what if” scenarios: what if advertising cost rises 20%? What if warranty spend is cut?

• Empower your team to negotiate better purchase deals, reduce prep spend, or refine marketing to improve margins.

Smart strategies to increase margin

• Negotiate purchase discounts or bulk deals.

• Audit your prep and refurbishment costs (valeting, parts, mechanical checks).

• Control advertising spend with ROI tracking.

• Bundle warranties, but ensure they are profitable at scale.

• Allocate overhead fairly across units, not all to high margin ones.

Call to Action / Next Steps

• Use your own vehicle data below and see your real margin per unit sold.
• Identify which cost items are bleeding profit, then benchmark with peers or test optimised proposals.
• Consider showcasing your margins with buyers (for trust) or calculating aggregate profits across your stock list.
