How much does each sale really earn after you pay for the product itself? Gross profit answers that question. The Gross Profit Calculator takes your sales and cost of goods sold, then shows gross profit in dollars.
It also shows your gross margin percentage and the share of revenue that goes to COGS. Shop owners, resellers, makers, and accounting students can all use it.

What the Calculator Does
You enter two numbers and press one button. The tool returns three cards.
- Gross Profit Amount: sales minus cost of goods sold, in dollars.
- Gross Margin Percentage: gross profit as a share of sales.
- COGS to Revenue Ratio: the part of each sales dollar spent on COGS.
The two percentages always add up to 100% for any sales figure above 0. Results for the sample numbers appear when the page loads.
How to Use It, Step by Step
- Enter your sales for the period in Total Net Sales / Revenue ($).
- Enter the direct cost of what you sold in Cost of Goods Sold (COGS) ($).
- Press Calculate Gross Profit. Enter 0 for COGS if you have none.
- Read the three cards under Gross Income Results.
Use sales after returns and discounts. Keep both numbers on the same time period, such as one month or one year.
The Gross Profit Formula
Gross profit is the simplest profit measure. It ignores rent, wages, and taxes on purpose.
Net Sales-COGS=Gross Profit÷Net Sales=Gross Margin %
- Gross profit = net sales - COGS.
- Gross margin % = gross profit ÷ net sales × 100.
- COGS ratio % = COGS ÷ net sales × 100.
Percentages show two decimal places. The dollar result uses commas and cents.
Worked Example
Tomas runs an online store that sells coffee gear. This year he booked $184,000 in net sales. The products he sold cost him $103,500, including freight to his warehouse.
| Result | Calculation | Output |
|---|
| Gross Profit Amount | $184,000 - $103,500 | $80,500.00 |
| Gross Margin Percentage | $80,500 ÷ $184,000 × 100 | 43.75% |
| COGS to Revenue Ratio | $103,500 ÷ $184,000 × 100 | 56.25% |
Tomas keeps about 44 cents of each sales dollar before overhead. His rent, ads, and staff must come out of that $80,500.
How to Read the Results
Gross Profit Amount is the money left to pay all other costs. If it is too small to cover them, the business loses money no matter how large sales look.
Gross Margin Percentage is the best number for comparing products, months, or competitors. A rising margin often means better pricing or cheaper supply.
COGS to Revenue Ratio is the flip side. If it climbs from 56% to 60%, your costs are growing faster than your prices.
A negative gross profit means COGS is higher than sales. Take $1,000 of sales and $1,500 of COGS. The cards read -$500.00, -50.00%, and 150.00%, and the first two turn red.
What Counts as COGS
COGS covers costs tied directly to the goods you sold. Think purchase price, materials, direct labor, and inbound freight. Rent, marketing, and office pay are operating expenses and stay out.
Gross profit is only the first step down the income statement. Subtract overhead, taxes, and interest with the net profit calculator. If you start from a unit cost and a price tag, the profit margin calculator is quicker.
Margin and markup are not the same thing. Markup divides profit by cost, while margin divides it by price. The markup calculator shows the difference.
Stock that sits on shelves ties up money. See how fast you sell it with the inventory turnover calculator. To find the sales needed to cover fixed costs, use the break-even point calculator. More tools are in the finance and business calculator hub.
Limitations and Assumptions
- Net sales must be above 0. A blank or 0 value shows a red message and N/A in all three cards.
- A blank COGS field shows a message that asks you to enter 0 if none. A typed 0 gives a 100.00% margin.
- The tool does not update as you type. Press the button after each change.
- Negative entries are rejected, and each field has a limit of 1,000,000,000,000.
- It does not split COGS by product or subtract returns for you.
FAQs About the Gross Profit Calculator
What is gross profit?
Gross profit is net sales minus the direct cost of the goods sold. It is measured before operating expenses, interest, and taxes.
What is the difference between gross profit and net profit?
Gross profit subtracts only COGS. Net profit subtracts every cost, including overhead, interest, and taxes. Net profit is always the smaller number for a business with overhead.
Is gross margin the same as markup?
No. A product that costs $60 and sells for $100 has a 40% gross margin. Its markup is 66.67%, because markup divides profit by cost.
What is a good gross margin?
It varies widely by industry. Retail, restaurants, and software firms all run very different margins. Compare your result with similar businesses and your own history.
Why do my results not change when I type?
The calculator only updates when you press Calculate Gross Profit. If a field is blank or invalid, a red message appears and the cards show N/A.
Can gross profit be negative?
Yes. If COGS is larger than net sales, you sell below cost. The result then shows a negative dollar amount and a negative margin, both in red.
