About classic profit margin
A classic margin calculator answers the oldest pricing question on a shop floor: if I sell at this price and it costs me that much, how much do I keep, and what percent of the price is that? Profit is selling price minus cost price. Classic profit margin is that profit divided by selling price, times 100. A $100 sale on a $70 cost produces $30.00 of profit and a 30% margin. The base is selling price, not cost. That is the distinction from markup. A $80 price on a $50 cost is $30.00 of profit and a 37.50% margin, while markup on cost would be 60%. If someone quotes “margin” but is adding a percent to cost, they are describing markup. The classic margin calculator stays on the selling-price definition used on many invoices and retail flash reports. This view is unit-level and gross. It does not subtract card fees, marketplace commissions, shipping you absorb, or overhead. A 30% ticket margin can become a thin operating margin after those items. If you need expenses in the picture, use a business margin path with an operating-expense line. If you need both margin and markup on the same pair of numbers, use a combined margin-and-markup view. Negative profit is possible if cost exceeds price; the formula still runs as long as selling price is positive. A zero cost produces 100% margin, which is a signal to check whether cost was omitted rather than a realistic product. Keep both inputs in the same currency and on the same unit (each, case, or hour). Use the classic margin calculator to sanity-check a $100 / $70 list price, an $80 / $50 promotional price, or a $120 / $90 tighter line. Compare the percent with category targets before you print tags. Confirm cost includes the extras you intend to recover, because a missing freight line inflates both profit and margin.
Profit = selling price − cost price; margin = profit ÷ selling price × 100.
Classic margin calculation examples
These worked examples use the same profit and selling-price margin formulas as the classic margin calculator.
| Input | Output | Note |
|---|---|---|
| $100 selling price; $70 cost | $30.00 | Profit is $30.00 and classic margin on the selling price is 30.00%. |
| $80 selling price; $50 cost | 37.50% | Profit is $30.00; 37.50% is profit divided by the $80 selling price, not markup on the $50 cost. |
| $120 selling price; $90 cost | 25.00% | A $30.00 profit on $120 is a 25.00% classic margin, a tighter return than the $100 / $70 case. |

Classic margin calculator FAQ
Is classic margin the same as markup?
No. Classic margin divides profit by selling price. Markup divides profit by cost. A $30 profit on an $80 price is a 37.50% margin and a 60% markup on a $50 cost.
How do I hit a target margin when I know cost?
Selling price equals cost ÷ (1 − target margin as a decimal). A $70 cost at a 30% margin needs a $100 price. Enter the resulting price here to confirm profit and the percentage.
Does the profit include discounts or card fees?
No. Profit is selling price minus cost price only. If you will discount, enter the expected net selling price. Card fees and commissions need to be subtracted separately or folded into cost if that is how you manage them.
What if cost is higher than selling price?
Profit is negative and margin is negative, which flags a loss on the unit. The classic margin calculator still reports the figures so you can see how far the price sits below cost.
Can I use another currency?
Yes, if selling price and cost use the same currency. Dollar formatting in the result is display only; the margin percentage does not depend on the currency symbol.
