Assumptions used

What this answer assumes

Gross margin check only. Include all real costs before using the result for a quote or report.

  • Profit margin uses net selling price as the denominator, not cost.
  • Markup uses total cost as the denominator, so margin and markup percentages are not the same.
  • Discount is applied to selling price before profit and margin are calculated.
  • Extra cost is added to cost before profit, margin and markup are calculated.
  • This is gross pricing arithmetic only. It does not include tax, VAT/GST, income tax, accounting policy, inventory timing, refunds or legal advice unless those effects are included in the entered costs.

Master’s Tip

How to use the result well

Master’s Tip: print the price, cost, discount and extra-cost lines before approving a quote. A margin that looks safe before card fees, freight, waste or callbacks can become weak once those real costs are added.

Formula

Net selling price = selling price × (1 − discount percent ÷ 100). Total cost = cost + extra cost. Gross profit = net selling price − total cost. Profit margin % = gross profit ÷ net selling price × 100. Markup % = gross profit ÷ total cost × 100.

Worked example

Selling price 150 with cost 100 and no discount gives gross profit = 150 − 100 = 50. Profit margin = 50 ÷ 150 × 100 = 33.33%. Markup = 50 ÷ 100 × 100 = 50%.

Questions

How do you calculate profit margin?

Subtract total cost from net selling price to get gross profit, then divide gross profit by net selling price and multiply by 100.

What is the difference between margin and markup?

Margin divides profit by selling price. Markup divides profit by cost. For example, 50 profit on a 150 sale is a 33.33% margin but a 50% markup on 100 cost.

Should discounts be included in profit margin?

Yes. If the customer pays a discounted price, use that net selling price as the denominator or the margin will be overstated.

Can profit margin be negative?

Yes. If total cost is higher than the net selling price, gross profit is negative and the margin shows a loss.

Does this calculator include VAT, GST or sales tax?

No. It is gross pricing arithmetic. Add tax only after deciding whether your prices and costs are tax-exclusive or tax-inclusive under the rules you follow.

Calculation note

Profit margin is a compact way to show how much of a sale remains after cost. It is useful for quotes, retail pricing, product comparisons and classroom business examples, but only when the selling price and cost basis are stated clearly.

Margin is measured from revenue

Profit margin asks what share of the selling price remains as gross profit. That is why the denominator is the net selling price, not the cost. Keeping the denominator visible prevents the common margin-versus-markup mistake.

Discounts and fees change the real margin

A quoted price is not always the money kept by the seller. Discounts, payment fees, freight, packaging, waste, callbacks and other direct costs can reduce the gross result. The calculator keeps those lines separate so the report can be audited.

A printable margin record protects a quote decision

For a small business, homeowner quote or classroom worksheet, the useful artifact is not just the percentage. It is the selling price, cost basis, discount, extra-cost assumption, formula, date and notes area kept together before a decision is made.
