Break-even analysis, ROI calculation, margin and markup pricing, and invoice reference generation for freelancers and small businesses.
The tools
Ordered by how often they are used. Every one is free and runs in your browser.
Background
Running a small business means making pricing and investment decisions without a finance department to check them. The underlying arithmetic is not complicated, but getting it slightly wrong — confusing margin with markup, for instance — quietly erodes profit on every sale you make.
These tools cover the calculations that come up most often when setting prices, evaluating a purchase or working out how much you need to sell to cover your costs. Each one explains the formula alongside the result so the reasoning is visible, not hidden.
Everything runs locally in your browser. Your revenue figures, cost structures and margins are yours alone — nothing is transmitted, logged or stored anywhere.
