Gross Profit Calculator
Calculate gross profit ($) and gross profit margin (%) instantly from sales revenue and cost of goods sold — with retail benchmarks and AI insights.
Summary
A Gross Profit Calculator computes the difference between sales revenue and cost of goods sold (COGS), then expresses it as both a dollar amount and a percentage. Retailers, supermarkets, restaurants and wholesalers use it to measure product profitability before operating expenses. Gross Profit = Revenue − COGS; Gross Margin % = (Gross Profit ÷ Revenue) × 100.

What is the Gross Profit Calculator?
The Gross Profit Calculator turns two inputs — net sales revenue and the cost of goods sold — into the two numbers every retail manager checks first thing in the morning: gross profit (in dollars) and gross profit margin (as a percentage). It works for a single SKU, a department, a store or a whole chain because the formula is identical at every level.
Gross profit isolates product profitability from store profitability. It excludes labour, rent, marketing and utilities — those sit further down the income statement as operating expenses. That separation is what makes the metric useful: it tells you whether the products themselves are pulling their weight, independent of how efficiently the store is being run around them.

Sanity-check client P&Ls and produce defensible margin reports.
Students
Learn the foundational retail and accounting formula behind every income statement.
Hospitality managers
Cost menus and bar offers to a target margin for each daypart.
Wholesalers
Quote landed-cost margins to trade customers without spreadsheet errors.
E-commerce sellers
Validate that promo prices on Amazon, Shopify and marketplaces still clear target margin.
Why this metric matters
Gross profit is the foundation of every retail income statement. Net profit, EBITDA and operating profit all start with it. A supermarket can ring up millions in weekly sales and still go broke if gross margin slips two points — because every downstream cost is calibrated to the gross profit available to fund it.
Operationally, gross margin is the single highest-leverage number a store manager controls. Pricing, promotional discipline, vendor negotiation, mix management and shrink control all show up here before anything else. Tracking GP daily makes problems visible while they're still cheap to fix; reviewing it monthly means you're paying for them by the time you find them.
Formula
Gross Profit ($)
Gross Profit = Sales Revenue − Cost of Goods Sold
Sales revenue is net of refunds and customer discounts and excludes sales tax. COGS is the landed cost of products sold (supplier invoice + inbound freight + duties).
Gross Profit Margin (%)
GP% = (Gross Profit ÷ Sales Revenue) × 100
Expresses gross profit as a share of sales. A 25% gross margin means $0.25 of every $1.00 in sales is gross profit, before operating costs.
Worked example
A neighbourhood supermarket sells $185,000 in a week. Total COGS from the inventory system is $138,750. Gross profit = $185,000 − $138,750 = $46,250. Gross margin = $46,250 ÷ $185,000 × 100 = 25.0%. Against a 26.5% target, the store is 1.5 points light — about $2,775 of missing profit in a single week, or ~$144,000 annualised if it persists.
Real-world examples
Supermarket
Produce category: $42,000 revenue, $27,300 COGS. GP $14,700 (35%). Above 30% target — protect with tight waste control.
Restaurant
$8 burger costs $2.40 in ingredients. GP $5.60 (70%). Healthy plate margin; review labour and rent at total P&L.
Bakery
$5 loaf with $1.10 ingredient cost. GP $3.90 (78%). High margin offsets short shelf life and overnight labour cost.
Coffee Shop
$4.50 latte with $0.55 milk/coffee cost. GP $3.95 (88%). Best-margin category; ideal upsell from food.
Hardware Store
$120 power tool with $78 landed cost. GP $42 (35%). Mid-band general merchandise margin — typical for the category.
Convenience
$2.50 soft drink with $1.30 cost. GP $1.20 (48%). Higher margin offsets lower basket value vs supermarket.
Pharmacy
$15 vitamin pack with $9 cost. GP $6 (40%). Front-of-store categories run higher than prescription dispensing.
E-commerce
$60 product, $24 COGS, $9 fulfilment. True GP $27 (45%) after pick/pack — not 60% from cost alone.
Wholesale
Case of 24 units sold at $96, costed at $72. GP $24 (25%). Volume model; protect with payment terms.

Common mistakes to avoid
1. Mixing tax-inclusive revenue with tax-exclusive cost
How to avoid: Reconcile both sides on the same basis. POS gross sales typically include VAT/sales tax; supplier invoices typically don't. Either net both or gross both — never split.
2. Forgetting inbound freight in landed cost
How to avoid: Add freight, duties and any direct purchase-related charges to the supplier invoice. Unaccounted freight quietly costs a full margin point over a year.
3. Confusing markup with margin
How to avoid: A 30% markup is only a 23% margin. Use the Retail Margin Calculator to convert cleanly, and never quote both interchangeably.
4. Ignoring shrink between stock counts
How to avoid: Reported GP can look healthy for weeks before a count catches the gap. Track waste and shrink separately and budget for the expected level.
5. Looking at GP% in isolation from turn
How to avoid: A 60% margin on a slow seller is worse than 18% on a fast one. Pair GP% with stock turn or GMROI before delisting decisions.
6. Using gross sales instead of net sales
How to avoid: Returns, refunds and unit-level discounts must be deducted before applying the formula, or margin will look better than it really is.
7. Treating labour as part of COGS
How to avoid: Store labour belongs in operating expenses, not COGS, in standard retail accounting. Mixing the two breaks comparability with peers and benchmarks.
8. Quoting margin against budget without context
How to avoid: A 1-point miss on a 25% category isn't the same as a 1-point miss on a 50% category. Always report dollar variance alongside percentage variance.
9. Recalculating only at month-end
How to avoid: Weekly GP review surfaces problems while they can still be fixed in-quarter. Monthly is too late for fresh-food departments.
10. Ignoring vendor rebates and allowances
How to avoid: Volume rebates, marketing allowances and supplier funding all change effective COGS. Build them into the calculation when material.
