Formula and symbols
Gross profit (GP) = Revenue (R) − Cost of goods sold (C)
Gross margin = GP ÷ R × 100
Markup = GP ÷ C × 100
| Symbol | Meaning |
|---|---|
| R | Total sales revenue before expenses |
| C | Direct costs attributable to the goods or services sold |
| GP | Amount remaining after subtracting COGS from revenue |
Gross profit is not net profit. Rent, administration, marketing, taxes, interest and other operating costs may still need to be deducted.
Worked example
A business records $50,000 in revenue and $30,000 in COGS. Gross profit is $20,000. The gross margin is 40%, while markup on cost is 66.67%. If operating expenses are $8,000, the simplified operating profit is $12,000.
How to interpret the result
Use gross margin to compare profitability across products or periods because it relates profit to sales. Use markup when setting prices from cost. A positive gross profit can still result in a business loss when operating expenses exceed gross profit.
Common mistakes
- Putting rent or advertising in COGS when it is an operating expense.
- Confusing margin with markup.
- Comparing businesses that classify direct costs differently.
- Ignoring returns, discounts and allowances when entering net revenue.
Frequently asked questions
What belongs in COGS?
COGS generally includes direct materials, direct labor and other costs directly required to produce or acquire what was sold. Accounting treatment varies by business and jurisdiction.
Can gross margin be negative?
Yes. It becomes negative when COGS is higher than revenue.
Why are margin and markup different?
Margin divides profit by selling price, while markup divides profit by cost. They use different denominators.
Should tax be included?
Normally use net sales excluding sales tax collected for authorities. Confirm the treatment required by your accountant.

Gross Profit Calculator business guide
A Gross Profit Calculator supports pricing reviews, product comparisons, budgeting and performance monitoring. Compare the Gross Profit Calculator result across consistent periods and investigate changes in selling prices, product mix, purchasing costs, freight, manufacturing efficiency and discounts. Higher revenue does not automatically create higher gross profit if direct costs rise faster.
For stronger analysis, calculate results for each product line as well as the whole business. A blended margin can hide one profitable product and another that loses money. Use the Gross Profit Calculator with conservative and expected assumptions, then compare the outcome with actual accounting records. Reconcile revenue after refunds, discounts and allowances, and classify costs consistently. Gross profit measures the amount remaining after COGS; it does not deduct every expense needed to operate the business.
Track both gross profit dollars and gross margin percentage. Dollars show the amount available to cover operating expenses, while the percentage makes comparisons easier across periods of different sizes. The Gross Profit Calculator is an educational planning tool and does not replace professional accounting advice.
