How to Read Your Results
Gross profit per unit is the amount remaining from one sale after direct cost.
Gross margin is expressed as a percentage of sales price, not cost.
Markup is expressed as a percentage of cost, so compare it carefully with margin targets.
Total gross profit scales with units sold when price and cost per unit stay constant.
Use gross profit alongside overhead and other expenses to assess wider profitability.
Assumptions & Important Notes
- Examples exclude indirect costs such as rent, administration, marketing, financing, and income tax.
- Prices and costs are assumed to remain constant across all units in each scenario.
- Amounts are illustrative and are not accounting, tax, or financial advice.

Frequently Asked Questions
Can the same gross margin apply at different sales volumes?
Yes. If price and direct cost per unit stay the same, margin remains unchanged while total gross profit changes with volume.
Can I use average cost per unit in the calculator?
Yes, provided the average cost is appropriate for the period and is used consistently with the selling price.
What happens if I enter zero units sold?
Total revenue and total gross profit will be zero, while the per-unit profit and margin can still be calculated.
Should discounts be included in the selling price?
For an estimate of realized profitability, use the price actually received after applicable discounts.
