Print| Gross Profit Amount | $0.00 |
The Margin Calculator Classic provides essential financial formulas for business owners, retailers, wholesalers, and e-commerce entrepreneurs to calculate gross profit margin percentage, net dollar profit, target selling prices, and markup percentages based on cost of goods sold (COGS).
The Classic Gross Margin & Markup Formulas
Gross margin measures profit relative to total revenue, whereas markup measures profit relative to wholesale cost:
Gross Profit ($) = Revenue (Selling Price) - Cost of Goods Sold (COGS)
Gross Profit Margin (%) = ( Gross Profit / Revenue ) × 100
Markup Percentage (%) = ( Gross Profit / Cost of Goods Sold ) × 100
Selling Price from Target Margin = Cost of Goods Sold / ( 1 - ( Target Margin % / 100 ) )
Where:
- Revenue (Selling Price): Total selling price billed to the customer per unit.
- Cost of Goods Sold (COGS): Direct unit cost to manufacture or purchase the inventory.
- Gross Profit: Net remaining revenue after deducting direct unit production/purchase cost.
Classic Margin vs. Markup Conversion Table
Reference key mathematical conversions between Gross Profit Margin and Markup Percentage across standard pricing tiers:
| Target Gross Margin % | Equivalent Markup % | Selling Price on $100 COGS | Dollar Gross Profit |
|---|---|---|---|
| 15.00% Margin | 17.65% Markup | $117.65 | $17.65 |
| 25.00% Margin | 33.33% Markup | $133.33 | $33.33 |
| 33.33% Margin | 50.00% Markup | $150.00 | $50.00 |
| 50.00% Margin (Keystone) | 100.00% Markup | $200.00 | $100.00 |
| 75.00% Margin | 300.00% Markup | $400.00 | $300.00 |
Step-by-Step Margin Calculation Example
Here is an example calculating selling price, gross profit, and markup for a product costing $75.00 COGS targeting a 40% gross profit margin:
- Calculate Selling Price:
$75.00 / ( 1 - 0.40 ) = $75.00 / 0.60 = $125.00 selling price. - Calculate Dollar Gross Profit:
$125.00 - $75.00 = $50.00 gross profit. - Verify Gross Margin Percentage:
($50.00 / $125.00) × 100 = 40.00% margin. - Calculate Equivalent Markup Percentage:
($50.00 / $75.00) × 100 = 66.67% markup.
Frequently Asked Questions
Why can gross profit margin never exceed 100%?
Gross margin represents profit as a percentage of total revenue. Since profit cannot exceed total revenue (unless cost is negative), gross margin cannot logically exceed 100%.
Can markup percentage exceed 100%?
Yes! Markup compares profit to wholesale cost. If an item costing $10 COGS is sold for $50, the gross profit is $40, producing a 400% markup (80% margin).
What is a good gross profit margin for retail?
Average gross margins vary by industry: grocery stores operate on 15% to 20% gross margins, general retail averages 30% to 50%, while B2B SaaS and digital software products often reach 70% to 85%+ gross margins.
How do I convert markup to margin quickly?
To convert markup to margin: Margin = Markup / ( 1 + Markup ) (e.g., 50% markup converts to 0.50 / 1.50 = 33.33% margin).
