Find your profit per unit and total profit — with an optional discount factored in
💡 Why This Matters Profit is the simplest, most direct measure of whether a sale was worth making. Whether you're pricing one item or a whole batch, this tells you exactly what you walk away with after costs.
Profit and profit margin aren't the same thing — profit is a dollar amount, while margin expresses that profit as a percentage of revenue, which is what actually lets you compare profitability across different price points fairly.

For a single item, profit = price − cost. For a batch of items, total profit = revenue − total cost, where revenue is unit price × quantity and total cost is unit cost × quantity. If a discount applies, it reduces the effective selling price before profit is calculated — so a 10% discount lowers both revenue and profit, not just the sticker price.
Profit per unit tells you how much you keep from each individual sale, while total profit scales that up across everything you sold. Both numbers only reflect the cost you entered — if that cost is strictly cost of goods sold (COGS), what you're calculating is technically gross profit, before overhead, payroll, and taxes come out.
This calculator assumes a flat cost per unit, which holds for most small businesses and individual sellers but breaks down for large-scale production, where economies of scale can lower the marginal cost of each additional unit. It also doesn't account for returns, damaged goods, or payment processing fees unless you build those into your cost figure yourself.
Use total profit to see whether a batch of sales was worth the effort, and profit per unit to compare pricing strategies at a glance. If you want profitability expressed as a percentage instead of a dollar figure — useful for comparing across products or businesses — pair this with a profit margin calculation next.
Example: You make metal boxes for $25 each and sell them for $33. Profit per unit = $33 − $25 = $8. Selling all 45 boxes you produced: total cost = 45 × $25 = $1,125, revenue = 45 × $33 = $1,485. Total profit = $1,485 − $1,125 = $360.
For one item: profit = price − cost. For a quantity of items: total profit = revenue − total cost, or (unit price × quantity) − (unit cost × quantity).
Gross profit is revenue minus cost of goods sold (COGS), before deducting overhead, payroll, taxes, or interest — it's an initial measure of profitability, not the final bottom line.
Profit is a dollar amount — revenue minus cost. Profit margin is that same profit expressed as a percentage of revenue, which makes it easier to compare profitability across different price points or businesses.
