GP% (Gross Profit Percentage) in sales measures profitability by showing the percentage of revenue remaining after deducting the Cost of Goods Sold (COGS), representing efficiency before operating expenses. It is calculated as Revenue − COGS Revenue × 100 R e v e n u e − C O G S R e v e n u e × 1 0 0 . A higher GP% indicates better efficiency in production and pricing.
Gross profit on a product is the selling price of your product minus the cost of producing it. For a service business, it's the selling price of your service minus the cost of the time spent doing the job. Gross profit also refers to total sales (also known as revenue or turnover) minus the total cost of sales.
A gross profit margin of over 50% is healthy for most businesses. In some industries and business models, a gross margin of up to 90% can be achieved. Gross margins of less than 30% can be dangerous for businesses with high gross costs.
First, subtract the COGS from a company's net sales. This is its gross revenues minus returns, allowances, and discounts. Then divide this figure by net sales to calculate the gross profit margin as a percentage.
A Good Gross Profit Margin is around 30 – 35% on average, but varies widely by industry.
Here are some general rules of thumb for gross margins:
20%: Healthy for manufacturers, distributors, and other businesses with physical production costs. 30-50%+: Solid margins for most service-based businesses with low overhead and production costs.
Gross profit (GP) is the number of dollars of profit (dollars billed minus expenses and dollars paid) your business earns, while gross margin (GM) is the percentage of your total billable revenue that constitutes profits (dollars of profit divided by total revenue dollars).
Gross profit measures a company's profit on each sales dollar after accounting for COGS. It's calculated as (Revenue - COGS) ÷ Revenue x 100.
For example, if a product sells for $100 and its cost of goods sold is $75, the gross profit is $25 and the gross margin (gross profit as a percentage of the selling price) is 25% ($25/$100).
Subtract all expenses, including cost of goods sold and operating expenses, from the total revenue to get the gross profit. Subtract other expenses such as interest payments and taxes from the gross profit to get the net profit.
Gross profit margin (GPM) is the percentage of your sales income remaining after you subtract your cost of goods sold (COGS). In short, it tells you how much money you're earning on each dollar after you deduct the direct cost of producing or purchasing your goods.
To take this one step further we should look at what our Gross Profit Percentage is (GP%). This can be achieved with a simple formula: (Net Selling Price – Net Cost) / Net Selling Price. So, for the same example as above the GP% on the Mojito sold at £8.50 will be 80%
A 20% gross profit margin means that for every dollar of revenue a business earns, it keeps 20 cents as gross profit after covering the direct costs (Cost of Goods Sold, or COGS) of producing or acquiring the goods or services sold; the remaining 80 cents goes to paying for those direct costs. This metric shows how efficiently a company converts revenue into profit before considering operating expenses, interest, and taxes.
Gross Profit Margin = (Gross Profit ÷ Revenue) × 100
That 40% margin means your business keeps $0.40 in gross profit for every $1 of sales before accounting for other operating expenses.
Differences between Gross Profit and Gross Margin
While gross profit and gross margin are measures of a company's profitability, they reveal different information about its financial health. Gross profit is an absolute dollar amount, while gross margin is a percentage.
Markup % = (Selling price – cost price) / cost price x 100. Gross profit % = (Selling price – cost price) / selling price x 100.
How do I calculate a 30% margin?
The core difference is the base used for calculation: Markup adds profit to the cost price, while Margin calculates profit as a percentage of the final selling price (revenue), meaning a 30% margin is a much larger percentage increase on cost than a 30% markup, translating to roughly a 42.9% markup for a 30% margin, and vice versa.
An 80% profit margin is exceptionally high and whether it's 'good' depends on the context. An 80% gross profit margin might be achievable for software or digital product businesses with low production costs.
Gross profit margin (calculation)
The gross profit margin is your gross profit divided by revenue, times 100.
If you divide your job costs by your gross margin of . 33, you'll end up with a sales price for your work of $26,530, which is really high. You'll probably catch that mistake. The more common mistake is to multiply job costs by the gross margin, and add the result to job costs.
What is a good GP number to aim for? Generally in a hospitality business, you should be aiming to achieve minimum 70% gross profit across all of your sales mix. Some items will likely be lower than 70%, and some greater.
