| Scenario | List Price | Discount | Net Price | Variable Cost | Unit Margin | Margin % | Break-Even Units |
|---|---|---|---|---|---|---|---|
| Standard product | $120.00 | $8.00 | $112.00 | $82.85 | $29.15 | 26.03% | 83 |
| Premium product | $185.00 | $10.00 | $175.00 | $110.60 | $64.40 | 36.80% | 38 |

Formula Used
1) Net Selling Price Per Unit
Net Selling Price = List Price − Discount Per Unit
2) Commission and Processing Fees
Commission Per Unit = Net Selling Price × Commission Rate
Processing Fee Per Unit = Net Selling Price × Processing Fee Rate
3) Total Variable Cost Per Unit
Variable Cost Per Unit = Product Cost + Labor + Packaging + Shipping + Other Variable Cost + Commission + Processing Fee
4) Unit Margin
Unit Margin = Net Selling Price − Total Variable Cost Per Unit
5) Margin and Markup
Unit Margin % = (Unit Margin ÷ Net Selling Price) × 100
Markup % = (Unit Margin ÷ Total Variable Cost Per Unit) × 100
6) Break-Even and Target Units
Break-Even Units = Fixed Costs ÷ Unit Margin
Target Units = (Fixed Costs + Target Profit) ÷ Unit Margin

FAQs
1) What is unit margin?
Unit margin is the profit left from one sold unit after subtracting all variable costs tied to that unit. It shows whether each sale adds value before covering fixed overhead.
2) Is unit margin the same as markup?
No. Unit margin compares profit to net selling price. Markup compares profit to cost. Both are useful, but they answer different pricing questions and should not be used interchangeably.
3) Why include commission and payment fees?
These charges often scale with each sale, so they behave like variable costs. Ignoring them can overstate real unit profitability and lead to weak pricing decisions.
4) What does break-even units mean?
Break-even units show how many units you must sell so total contribution covers fixed costs exactly. Beyond that point, additional positive margin usually becomes operating profit.
5) Can a product have good revenue but poor margin?
Yes. High revenue can hide weak margins when discounts, shipping, commissions, and processing fees rise too much. Margin analysis reveals whether sales volume actually creates profit.
6) What if the calculator shows a negative unit margin?
That means every extra unit sold reduces profit. You usually need a higher price, smaller discount, lower variable cost, or a different sales mix before scaling volume.
7) Should taxes be included in unit margin?
Usually no, if taxes are collected and remitted separately. Many teams analyze margin using net revenue and operating costs only. Follow your accounting policy for final reporting.
8) When should I review unit margin?
Review it whenever price, discount policy, sales channel, shipping cost, commission plan, or supplier cost changes. Frequent review helps protect profitability during growth and promotions.
