Business Calculators

Business calculators are free online tools that answer the money questions behind running a company. They cover what to charge, how much you need to sell, and what the business is worth. Calcxi's business tools cover markup, profit margin, break-even analysis and business valuation, all running entirely in your browser with no sign-up.

Start with markup or margin, depending on which way round you think. Pricing is the input to everything else: the profit on each sale determines your break-even volume, and years of that profit are what a buyer pays a multiple of. If your pricing is wrong, the other calculators will faithfully compute the consequences of that wrongness.

Markup is a share of your cost, margin is a share of your selling price. A 50% markup is only a 33.3% margin. Margin can never reach 100% while a cost exists, while markup routinely passes it. Convert with margin equals markup divided by one plus markup. Confusing the two is the most common and most expensive pricing error there is, which is why the Markup Calculator and the Profit Margin Calculator both show the two figures together.

Subtract the cost from the selling price, divide by the cost, then multiply by 100. An item costing 80 and selling for 100 carries a 25% markup. To go the other way, selling price equals cost times one plus the markup as a decimal. The Markup Calculator does both directions and also prices a job made of several cost lines.

Subtract cost from revenue to get profit, divide by revenue, multiply by 100. Sell for 100 at a cost of 60 and the margin is 40%. The markup on that same trade is 66.7%, because markup divides by cost instead. The Profit Margin Calculator shows both together so the two never get confused.

Divide your fixed costs by your contribution margin, which is the selling price per unit less the variable cost per unit. With 10,000 of fixed costs, a price of 50 and a variable cost of 30, break-even is 500 units. The Break-Even Calculator also plots the chart, adds a target profit and shows your margin of safety, and the guide on how to do a break-even analysis works through a full example.

A range, not a figure. Different valuation methods applied to the same accounts routinely disagree by a factor of three or more, and the spread between them is your realistic negotiating range. The Business Valuation Calculator runs six methods at once and reports the range rather than pretending to a single answer.

Yes, and this is where quotes quietly turn into losses. Markup pays your overhead first, and only what is left is profit. If your overhead runs at 25% of direct cost, a 25% markup is exactly break-even rather than a 25% return. The job pricing tab of the Markup Calculator takes an overhead rate and shows you what actually remains.

Because we would have to invent the number. Valuation multiples and average margins are specific to a sector, a size band, a country and a year, and a figure lifted from one market is misleading in another. Instead the tools show you what a change to that number does, and the articles explain where to source a defensible one for your own market.

The arithmetic is exact and every formula comes from a named published source. Valuation definitions come from the International Business Brokers Association, markup, margin and discounted cash flow from Corporate Finance Institute, and break-even from OpenStax managerial accounting. The estimates are still estimates. Read our Calculator Accuracy Policy for how each was verified.

No. They are for understanding the shape of a decision and preparing for a conversation. Anything binding, whether that is a sale, a tax filing, a partnership settlement or raising money, needs a qualified accountant or valuer licensed in your country. How revenue and cost of goods are even defined varies by jurisdiction.

Yes. All four let you pick a currency symbol or use plain numbers, and the maths is currency neutral because these are ratios between costs, prices and earnings. What is not universal is what counts as a good margin or a fair multiple, which is exactly why the tools ask you to supply those rather than assuming them.

No. Every calculation happens inside your browser. Your revenue, costs, salaries, valuation multiples and everything else you type are never transmitted to our servers or stored anywhere. That matters more here than on most calculators, since these are the numbers you would least want leaked. See our Privacy Policy.

No. Every tool on Calcxi is free with no sign-up, no login, no trial and no email gate on the results. Several of the best known business calculators hold your answer behind a form. These do not.

The category is being built out from pricing outwards. You can also browse our Finance Calculators for personal money tools, Health and Fitness Calculators, and Construction Calculators. Have a request? Contact the Calcxi team and we will prioritise it.
