Introduction
This free Profit Calculator shows you how much money your business really keeps. Enter your sales and your costs, and it gives you your gross profit, net profit, and profit margin right away.
The tool has five modes, so it fits almost any question you have about profit:
- Basic Profit — find gross profit, net profit, and margin from your revenue, cost of goods sold, operating expenses, and tax.
- Profit Margin — solve for margin, revenue, or cost. Fill in two boxes and the third one fills itself.
- Markup — set a price from your cost, or check the markup on a price you already use.
- Break-Even — see how many units you must sell before you start making money with our break-even calculator logic built in.
- Multi-Product — compare many products at once and spot which one earns the most and which one drags you down.
You also get a step-by-step solution, a chart, and a plain-language summary of what the numbers mean. A benchmark bar compares your margin to a typical margin in your industry, like retail, e-commerce, or SaaS. The what-if sliders let you raise or lower revenue and costs to see how profit changes.
Pick from ten currencies, switch between totals and per-unit results, or turn on high contrast mode for easier reading. Nothing is saved or sent anywhere — the math runs right in your browser.
How to use our Profit Calculator
Enter your sales, costs, and prices, and the profit calculator shows your gross profit, net profit, profit margin, markup, break-even point, a step-by-step solution, and a chart.
Currency: Pick the money type you use. All results show in that currency. If you sell across borders, a currency calculator helps you convert totals first.
Industry benchmark: Pick the business type closest to yours. The tool compares your margin to a typical margin for that field.
Results view: Choose "Totals" to see full amounts, or "Per unit" to split the numbers by each item sold.
High contrast mode: Turn this on for bigger color contrast and easier reading.
Mode tabs: Pick Basic Profit, Profit Margin, Markup, Break-Even, or Multi-Product. Each tab asks for its own inputs.
Revenue (total sales): Type all the money you took in from sales for the period.
Cost of Goods Sold (COGS): Type the direct cost of the goods or services you sold, like materials and shipping. Restaurants and cafés can size this up with a food cost calculator.
Units sold: Type how many items you sold. This gives you per-unit profit. Leave it blank if you don't need it.
Include operating expenses: Turn this on and type your rent, wages, ads, and software costs to get net profit. An expense calculator is handy if you need to add those up first.
Include tax: Turn this on and type your tax rate as a percent. Tax is taken from profit after expenses. Company filers can cross-check the rate with a corporation tax calculator or an effective tax rate calculator.
Solve Margin, Revenue, or Cost: In the Profit Margin tab, pick the one value you want the tool to find. Then fill in the other two boxes.
Profit margin (%): Type profit as a percent of your selling price. It must be under 100%.
Solve Selling Price or Markup: In the Markup tab, pick which value to find. Fill in the rest.
Cost price: Type what one unit costs you to make or buy.
Markup (%): Type the extra percent you add on top of your cost to set the price.
Selling price: Type the price you charge for one unit. If you plan to run a sale, test the new price in the discount calculator first.
Fixed costs: In the Break-Even tab, type costs that stay the same each period, like rent and insurance.
Variable cost per unit: Type the cost that goes up with each unit you sell, like materials and packaging.
Expected units sold: Type how many units you plan to sell. The tool shows if that beats break-even.
Product rows (Multi-Product): Type a product name, units sold, price per unit, and cost per unit for each line. Use "Add product row" for more items, or the trash button to remove one.
Revenue and cost sliders: Drag these to test what happens if sales or costs go up or down by a set percent.
Calculate and Reset: Press Calculate to see your results. Press Reset to bring back the starting numbers.
What Is Profit?
Profit is the money your business keeps after you pay your costs. The basic profit formula is simple: Profit = Revenue − Costs. Revenue is all the money you take in from sales. Costs are everything you spend to make and sell your product. If revenue is bigger than costs, you made a profit. If costs are bigger, you took a loss.
Gross Profit vs. Net Profit
There are two main kinds of profit, and they answer different questions.
- Gross profit = Revenue − Cost of Goods Sold (COGS). COGS is the direct cost of what you sold, like materials, factory labor, or the wholesale price you paid. Gross profit shows if your product itself makes money — see the gross profit margin calculator for a percentage view.
- Net profit = Gross profit − operating expenses − taxes. Operating expenses are things like rent, salaries, ads, and software. Net profit is your real bottom line — the money you actually get to keep. Lenders and buyers often look at EBITDA alongside it.
What Is a Profit Margin?
A profit margin turns your profit into a percent so you can compare it to other months, products, or businesses. The formula is Margin = (Profit ÷ Revenue) × 100. A 20% net margin means you keep 20 cents out of every dollar you sell. If you want to track how that percent moves month to month, the percent change calculator and the year over year growth calculator both help.
Margin vs. Markup
People mix these up all the time, but they are not the same number. Margin is measured against your selling price. Markup is measured against your cost.
- Margin = (Price − Cost) ÷ Price
- Markup = (Price − Cost) ÷ Cost
Example: a shirt costs you $10 and sells for $20. That is a 50% margin but a 100% markup. Same dollars, two different percents. Using markup when you meant margin is a common way to underprice a product and lose money.
What Is Break-Even?
Break-even is the point where you make exactly zero — no profit, no loss. To find it, split your costs into fixed costs (rent, insurance, salaries — these stay the same no matter how much you sell) and variable costs (materials, shipping, packaging — these go up with each unit sold).
Each sale gives you a contribution margin: Price − Variable cost per unit. That is the amount left over to help pay your fixed costs. Then:
Break-even units = Fixed costs ÷ Contribution margin per unit
Sell fewer units than that and you lose money. Sell more and every extra unit is profit.
What Counts as a Good Margin?
It depends on your industry. Grocery stores often live on 1–3% net margins because they sell huge volume. Software and consulting firms can hit 15–25% or more. Retail and restaurants usually sit in the middle. Always compare your margin to businesses like yours, not to a general average.
How to Improve Profit
- Raise prices. Even a small price bump goes almost straight to profit, since your costs stay the same.
- Lower COGS. Negotiate with suppliers, buy in bulk, or cut waste. Watch shipping costs too — they hide inside COGS more often than owners expect.
- Trim operating expenses. Look at subscriptions, ad spend, and space you don't use. If you sell online, marketplace fees matter: check the eBay fee calculator, Etsy fee calculator, Amazon FBA calculator, or PayPal fee calculator.
- Sell more of your best items. Push the products with the highest margins, not just the ones that sell the most.
- Drop losers. A product with a negative margin drags down your whole business.
- Watch what customers cost you. Compare your customer acquisition cost to your customer lifetime value — if CAC is close to CLV, growth is eating your profit.
Why Tracking Profit Matters
High sales do not mean a healthy business. A shop can bring in $1 million and still lose money if costs are out of control. Checking your gross margin, net margin, and break-even point on a regular basis tells you when to raise prices, cut costs, or change what you sell — before a small problem turns into a big one.
