Calcxi: Break-Even Calculator

Break-Even Calculator: Formula, Chart & Margin of Safety

Visit calcxi.com ↗Alternativestop 11% of September 2026

What it does

Free break-even calculator with a live break-even chart. Find your break-even point in units and revenue, add a target profit, margin of safety and multi-product mix.

Work out how many units you need to sell to cover your costs, in units and in revenue, with a break-even chart, target profit, margin of safety and a multi-product mode. Works in any currency. Rent, salaries, software, insurance. Costs that do not change with how much you sell. Materials, packaging, payment fees, shipping. Costs that rise with every extra sale. Break-even moves far more than the input that caused it. That leverage is the whole reason to run this before changing a price. If you sell more than one thing, a single break-even number is meaningless on its own. Enter your product mix and this works out the weighted average contribution margin, then splits the break-even volume…from calcxi.com

  • OwnTime – a chess clock for your day's priorities▲111

    I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up.
