Why we built this
A note from the editorial team
Honest math
Every formula is shown in plain English. If we use an assumption (like FSI's 600-hour estimate for Spanish), we say so — and link the source.
No fake precision
If a result depends on six unknowable inputs, we show a range — not a confident number to the cent. Real life is messier than a marketing calculator.
Built to be read
Each calculator is paired with a 1,200-to-1,800-word article explaining the why, the trade-offs, and the edge cases. Tools without context are just buttons.
"We started Calcumatrix because the calculator we needed — a true-hourly-wage tool that counted commute and unpaid prep — did not exist. So we wrote it. Then we wrote 34 more."
— The Calcumatrix Editorial Team

Questions, corrections, ideas?
We answer every email ourselves — usually within two business days. If a calculator gave you a result that surprised you, told us our assumptions are wrong, or you want a tool we haven't built yet, we want to hear about it.
