Margin Calculator — Free Online Tool

What Is Margin Calculator?

A free online margin calculator for e-commerce sellers, retailers, and business owners. Enter your revenue (selling price) and cost (COGS) to instantly see gross profit, margin percentage, markup percentage, break-even price, and recommended selling price for a target margin.

Profit margin is one of the most important metrics in any business. It tells you how much of each dollar of revenue is actually profit after accounting for costs. Margin Calculator computes gross profit, margin percentage, markup percentage, break-even price, and target margin pricing — everything you need to price products and evaluate profitability.

Enter the revenue (selling price) and cost (COGS — cost of goods sold). The calculator immediately shows the gross profit amount and the margin percentage. For example, a product sold for $100 that costs $60 to produce has a gross profit of $40 and a margin of 40%. That means 40% of the selling price is profit.

The markup percentage is also displayed — this is the profit expressed as a percentage of the cost, not the selling price. For the same $100 product costing $60, the markup is 66.7% ($40 profit ÷ $60 cost). Understanding the difference between margin and markup is critical for accurate pricing.

The break-even price shows the minimum selling price needed to cover costs (zero profit). The target margin section lets you enter a desired margin percentage, and the calculator shows the selling price needed to achieve it. For example, if you want 50% margin on a $60 cost, the selling price must be $120. The per-dollar breakdown shows how much of each dollar goes to cost vs. profit.

Real-World Use Cases for Margin Calculator

Pricing a Product to Achieve a Target Margin

You manufacture a widget with a COGS of $15. You want a 60% margin. Enter cost $15, desired margin 60%. The calculator shows the selling price should be $37.50. The current margin at $37.50 is 60%, markup is 150%. Use this to set your retail price confidently.

Analyzing the Margin on an Existing Product

You sell a subscription for $49/month with server and support costs of $15/month. Enter revenue $49, cost $15. Gross profit is $34, margin is 69.4%. This is a healthy margin for a SaaS product. The break-even price is $15 — you have a strong buffer above costs.

Determining if a Discounted Price Still Profits

Your $80 product (cost $35) is on sale for $60. Enter revenue $60, cost $35. Margin at full price is 56.3%. At sale price, margin drops to 41.7%. The markup at sale price is 71.4%. The discounted margin of 41.7% is still healthy, so the sale makes sense.

Pro Tips for Margin Calculator

1Margin and markup are not the same. A 50% margin means 50% of revenue is profit. A 50% markup means profit is 50% of cost. Confusing them leads to mispricing.
2Industry benchmarks vary widely: retail 20-50%, SaaS 70-80%, restaurants 3-15%, consulting 50-80%. Know your industry's typical margin range.
3Use the target margin feature for pricing new products. Start with your desired margin and let the calculator determine the selling price, rather than starting from cost.
4The break-even price is your minimum. Any price above it generates profit, but ensure the margin is high enough to cover operating expenses beyond COGS.
