What we do
Manufacturing engineers spend too much time rebuilding the same spreadsheets over and over. We built factorycalc.io to fix that — a growing library of browser-based calculators covering takt time, OEE, cycle time, line balancing, and more.
Every tool is purpose-built for production environments. Enter your numbers, get your answer instantly, and move on. No accounts, no data stored, no nonsense.
Fast
All calculations run in your browser. No server round-trips, no waiting.
Accurate
Formulas follow lean manufacturing standards and APICS definitions.
Free
Every tool is free to use. We're supported by non-intrusive advertising.
Our tools
We're continuously adding new calculators. Here's what's available today:
How we're funded
factorycalc.io is free because it's supported by advertising. We show a small number of relevant, non-intrusive ads from the Google AdSense network. We do not sell your data, require an account, or place any content behind a paywall.
