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

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
