What does a dealer earn on one car sale? Take a $31,000 sale on a car with a $28,000 invoice cost and a 2 percent holdback. The gross profit is $3,620, and the gross margin is 11.68 percent.
Dealer gross profit equals the selling price minus the invoice cost, plus the holdback. In the tool, holdback is the selling price times the holdback percent, divided by 100. Gross margin is that profit divided by the selling price. The $31,000 sale above gives $3,620 profit and an 11.68 percent margin.
What One Sale Is Worth to the Dealer
Dealer gross profit, also called vehicle gross profit, is what one sale leaves after the dealer pays the invoice cost. It is a single-sale figure, so it covers one car and one deal. This guide follows that sale from price to percentage.
Wikipedia describes gross margin as the selling price of an item less its cost of goods sold, expressed as a percentage. The Dealer Margin Calculator applies that same idea to a vehicle. It then adds the holdback to the profit.
Three inputs drive the result: the invoice cost, the selling price and the holdback percent. The tool uses the selling price only. It has no MSRP input, so a sticker price never enters the math.
The diagram below shows the four steps in order, using the worked example from this guide.
Profit Before Holdback
Profit before holdback is the selling price minus the invoice cost. For the tool’s example, $31,000 minus $28,000 leaves $3,000. That is the first number to find, and the rest builds on it.
The subtraction is plain arithmetic. A price below the cost gives a negative result at this step. The holdback is added afterward, so it never changes this first subtraction.
This step uses only two inputs, the cost and the price. Changing either one moves the profit directly. Raise the price by one dollar, and the profit before holdback rises by one dollar.
In the tool, the invoice cost is the dealer cost number you type in. The tool takes that figure as given and does not look it up. For a plain profit on any price and cost, the profit calculator does the subtraction alone.
The Dealer Holdback Add-On
Holdback is the last piece of dealer gross profit. The tool’s help text calls it a “manufacturer refund, as a percent of price.” The tool treats it as a percent that you type in.
To find the dollar amount, the tool multiplies the selling price by the holdback percent and divides by 100. At 2 percent of $31,000, the holdback is $620. Adding that to $3,000 gives a gross profit of $3,620.
Notice that the holdback depends on the price and not on the cost. Two sales with the same price and different costs share the same holdback dollars in the tool. Only the profit before holdback changes between them.
The table lists every step of the example. Read it from the top to the bottom.
| Step | Calculation | Result |
|---|---|---|
| Selling price | Typed in | $31,000 |
| Invoice cost | Typed in | $28,000 |
| Profit before holdback | $31,000 – $28,000 | $3,000 |
| Holdback at 2 percent | $31,000 x 2 / 100 | $620 |
| Gross profit | $3,000 + $620 | $3,620 |
| Gross margin | $3,620 / $31,000 x 100 | 11.68 percent |
The manufacturer sets holdback terms, and they vary. The tool cannot know the terms of your deal, so the percent is always your own entry. Check the current manufacturer terms before you rely on any figure.
The bar below splits the $3,620 into its two parts. The holdback is the smaller piece, yet it still adds to the profit.
Gross Margin on a Car as a Percentage
Gross margin on a car is the gross profit divided by the selling price, times 100. For the example, 3,620 / 31,000 x 100 gives 11.68 percent. The price is the base, which makes the figure a margin.
Because the price is the base, the margin tells you how much of each sale dollar is gross profit. Here, 11.68 percent means each dollar of the selling price carries 11.68 cents of gross profit. A larger price with the same dollar profit gives a smaller margin.
The markup calculator covers that case. The margin calculator handles a plain price and cost pair.
The holdback lifts the margin because it raises the profit while the price stays the same. The tool shows the dollar profit and the percentage, so you see the sale from two angles. For the gap between gross and net margin, read this guide on gross margin versus net margin.
Two More Worked Examples
The tool ships two presets that show the formula at other sizes. The table sets them beside the first example.
| Sale | Cost and price | Holdback | Gross profit | Margin |
|---|---|---|---|---|
| Example 1 | $28,000 and $31,000 | 2 percent ($620) | $3,620 | 11.68 percent |
| Preset 35k to 37k | $35,000 and $37,000 | 1.5 percent ($555) | $2,555 | 6.91 percent |
| Preset 20k to 23k | $20,000 and $23,000 | None | $3,000 | 13.04 percent |
The 35k to 37k preset starts with $2,000 before holdback. The holdback is 1.5 percent of $37,000, which is $555. Gross profit is $2,555, and the margin is 6.91 percent.
The 20k to 23k preset has no holdback. Profit is just $23,000 minus $20,000, which is $3,000. The margin is 13.04 percent.
Compare the first and third sales. The first earns more dollars, $3,620 against $3,000. The third shows the higher margin, 13.04 against 11.68 percent. Dollars and percentages answer different questions, so read both.
What the Tool Leaves Out
The tool is built for one clean calculation, so its scope is narrow. The list below shows what it does not model.
- Fees, tax and overhead. The tool has none of these, so the result is a gross figure only.
- MSRP. The tool uses the selling price only and has no MSRP input.
- The terms of your deal. Holdback is set by the manufacturer and varies, and real sales depend on many terms the tool does not model.
- Full copy. The Copy button copies only the headline value, not the whole breakdown.
Each omission matters when you read the result. Fees, tax and overhead are not in the tool, so the gross figure is not what remains after those items. The tool shows the gross number only, and the rest is outside its scope.
This guide quotes no typical dealer margin, because the tool cannot know one. It also gives no advice to buy or sell a vehicle. Treat every output as arithmetic on the numbers you enter.
Checking Your Own Numbers
Four short steps rebuild any result by hand. Run them once and the tool’s output stops being a black box.
- Subtract the invoice cost from the selling price.
- Multiply the selling price by the holdback percent, then divide by 100.
- Add the two results to get the gross profit.
- Divide the gross profit by the selling price, then multiply by 100.
Keep the order fixed. The holdback uses the selling price, not the profit, so multiply first and then add. Dividing by the cost instead of the price gives a markup, not a margin.
Try it on the 35k to 37k preset. The first step gives $2,000, and 37,000 x 1.5 / 100 gives $555. The total is $2,555. A mismatch usually points to a mistyped digit or a wrong percent.
This is general information, not advice to buy or sell a vehicle. It makes no claim about any dealer’s real margin.
Enter the invoice cost, selling price and holdback percent in the Dealer Margin Calculator to see the gross profit and the margin.
FAQs About Dealer Gross Profit
How is dealer gross profit calculated?
Subtract the invoice cost from the selling price, then add the holdback. A $31,000 sale with a $28,000 cost and a 2 percent holdback gives $3,000 plus $620, which is $3,620.
What is dealer holdback?
In the tool, holdback is a manufacturer refund entered as a percent of the selling price. At 2 percent of $31,000 it is $620. The manufacturer sets the real terms, and they vary.
How do I find the gross margin on a car?
Divide the gross profit by the selling price, then multiply by 100. For $3,620 on a $31,000 sale, the gross margin is 11.68 percent.
Is the margin based on cost or on price?
In the tool, it is based on the selling price. A percentage based on the cost is called markup, which is a different figure.
