Car dealer KPIs: the numbers to track every week
Car dealer KPIs for used car businesses: gross profit per unit, days in stock, lead conversion, recon cost and how to set and review targets weekly.
· 7 min read
The car dealer KPIs that matter most for a used car business are gross profit per unit, average days in stock and the share of aged stock, lead-to-sale conversion, reconditioning cost and time to line, and price to market. Reviewed weekly, these few numbers show whether you are buying right, selling fast enough and keeping costs under control – long before the monthly accounts do.
Car dealer KPIs: which matter most for a used car dealer?
A used car dealer needs a short list of KPIs that cover the whole cycle: buying, preparing, pricing, selling and profit. Eight are enough for most businesses.
| KPI | Formula | What it tells you |
|---|---|---|
| Gross profit per unit (GPU) | (Sale price net of VAT − purchase price − recon − direct costs) ÷ cars sold | Whether you buy and sell at the right prices |
| Average days to sell | Sum of days in stock of cars sold ÷ cars sold | Speed of the business |
| Aged stock share | Cars over 60 (or 90) days ÷ total stock | Future write-downs |
| Time to line | Days from purchase to advert | Preparation efficiency |
| Recon cost per unit | Reconditioning spend ÷ cars prepared | Buying quality and workshop costs |
| Price to market | Your price ÷ market price of comparable cars | Whether listings are competitive |
| Lead conversion | Cars sold ÷ qualified leads | Sales effectiveness |
| Finance and add-on penetration | Deals with finance (or warranty) ÷ cars sold | Extra income per sale |
Add a cash or capital KPI if you use stocking finance: total funded stock and finance cost per car sold.
What is a good gross profit per used car?
There is no universal "good" figure: gross profit per unit depends on price segment, country, VAT scheme and cost base. The useful target comes from your own overheads.
Target GPU = (monthly fixed costs + target monthly profit) ÷ cars sold per month
Example:
- Fixed costs: rent, salaries, insurance, software, advertising: €38,000 a month
- Target profit: €10,000 a month
- Sales: 30 cars a month
- Required GPU: (38,000 + 10,000) ÷ 30 = €1,600 per car
Calculate GPU after VAT. For margin-scheme cars, deduct the VAT on the margin – at 19% in Germany, a €2,000 gross margin leaves €1,680.67. Our article on car dealer profit margin breaks this down further. If your GPU target is not achievable in your segment, the problem is volume, overheads or stock mix, not the sales team.
Look at the distribution as well as the average. Ten cars at €3,000 and ten at €200 average €1,600 but tell you that half of your buying decisions are weak.
For car dealers
Know your margin before you buy
MyCarDealer compares any car from an auction or listing with the market in your country and shows the net margin after VAT, transport and costs – and the maximum bid.
Request accessStock age and days to sell
Stock age is the KPI that predicts next month's profit. Every car that ages past your normal selling time will probably need a price reduction or be wholesaled at a loss.
Track weekly:
- Average age of current stock.
- Share of stock over 60 and over 90 days.
- Average days to sell for cars sold this month, by segment.
A rising share of aged stock is a buying problem first and a pricing problem second. See stock turn for used cars for how to calculate turn and the daily cost of holding a car.
How do I measure lead conversion in a dealership?
Lead conversion is the number of cars sold divided by the number of qualified leads in the same period. A qualified lead is a real person interested in a specific car or type of car – exclude spam, trade offers and duplicates.
Break it into steps to see where deals are lost:
- Leads → contact made: were leads answered quickly?
- Contact → appointment or video viewing: was the answer convincing?
- Appointment → sale: did the car and the deal meet expectations?
If leads are not turning into appointments, look at lead response speed and quality. If appointments do not become sales, look at car condition, pricing and negotiation. A CRM that records the source and outcome of each lead makes these numbers available without manual counting.
Also track leads per car per week. A car with almost no enquiries after a week is overpriced or badly presented; one with many enquiries and no sale may have a problem visible only at the viewing.
Reconditioning cost and time to line
Reconditioning cost per unit and time to line show how well cars are bought and prepared. Track recon cost against the budget you set when buying; consistent overspend means cars are bought in worse condition than assumed, or the workshop does more than needed.
Time to line – from purchase to advert – is the part of days in stock in which a car cannot sell. Targets of a few working days are realistic for standard cars; our guide to the reconditioning workflow shows where the days are typically lost.
Price to market
Price to market compares your asking price with the current market price of comparable cars – same model, generation, engine, year range and similar mileage. A car listed at 106% of market will usually sit; one at 94% may be giving away margin.
Measure it for every car at listing and at each weekly review. MyCarDealer calculates the market price as a weighted median of comparable listings in your country, along with the net margin after VAT; you can try it on one car with a free valuation.
How often should dealer KPIs be reviewed?
Review operational KPIs weekly and financial KPIs monthly.
| Frequency | KPIs | Who |
|---|---|---|
| Daily | New leads, unanswered leads, cars arrived | Sales and preparation |
| Weekly | Stock age, aged-stock share, time to line, price to market, leads per car, conversion | Owner or manager with team |
| Monthly | GPU, recon cost per unit, finance penetration, cars sold, stock turn | Owner, with accountant figures |
| Quarterly | Targets, pay plans, stock mix, channels | Owner |
A weekly review should take less than an hour and end with decisions: which cars to reduce, which to wholesale, what to buy next and which leads need attention.
Setting targets for each KPI
Set targets from your own history, then improve them step by step. A practical approach:
- Collect three to six months of data for each KPI.
- Set the first target slightly better than your average – not at the level of the best month.
- Assign one person responsible for each KPI.
- Review weekly; change one thing at a time.
- Re-set targets each quarter.
Avoid tracking more than you can act on. Ten numbers reviewed every week beat fifty numbers in a report nobody reads.
Frequently asked questions
Car dealer KPIs: which matter most for a used car dealer?
Gross profit per unit, average days to sell and the share of aged stock, time to line, reconditioning cost per unit, price to market, lead conversion and finance or add-on penetration. Together they cover buying, preparation, pricing and selling.
What is a good gross profit per used car?
It depends on your segment and costs. Calculate the target as monthly fixed costs plus target profit, divided by cars sold per month. A dealer with €38,000 of monthly costs aiming for €10,000 profit on 30 sales needs €1,600 per car.
How do I measure lead conversion in a dealership?
Divide cars sold by qualified leads in the same period, then break it into steps: leads answered, appointments made and sales closed. Each step shows a different problem – response speed, persuasion, or the car and the deal.
How often should dealer KPIs be reviewed?
Check leads daily, review stock age, pricing, time to line and conversion weekly, and look at gross profit, reconditioning cost and stock turn monthly. Targets and pay plans can be reviewed quarterly.
Should gross profit be measured before or after VAT?
After VAT. For margin-scheme cars the VAT on the margin is a real cost – about 16% of the gross margin at a 19% rate – so measuring before VAT overstates profit.
