About Small Business Profit Calculator

Know your margin, your profit, and how many sales it takes to break even

A product can sell every day and still lose money if the price, the unit cost, and the overhead underneath it are never worked out on paper. This Small Business Profit Calculator brings those three checks together in one place so an owner can test a price before committing to it. The margin and markup section shows what you keep from each sale and how that compares to what you added on top of cost — two numbers owners often confuse, with very different meanings when you negotiate a discount or a supplier raises prices. The business profit section rolls the same thinking up to a full period: enter revenue, cost of goods sold, and operating expenses to see gross profit, net profit, and the margin left after the bills that keep the doors open. The break-even section answers a plainer question: at this price and this variable cost, how many units must you sell just to cover fixed costs before any profit begins? Use it when you are pricing a new offer, checking whether a busy month was actually profitable, or deciding if a price increase needs to happen before you hire, expand, or take on more overhead.
