HR calculators for people teams
No signup, no spreadsheet. Each tool shows its formula, explains how to read the result, and links to a deeper guide.
About these tools
Every calculator here is free, requires no signup, and shows its formula in full - the math runs in your browser, and nothing you enter is stored or sent to a server. Each one can also be embedded on your own site with a copy-paste snippet from its page, and links to a deeper guide that covers the edge cases the one-line formula hides.
