About

HourSums is a small collection of practical calculators for people who track work hours: hourly workers, freelancers, contractors and small employers.

The tools are deliberately simple. There is no account to create, nothing to install and no spreadsheet to maintain. Every calculation runs in your browser, and your entries stay on your own device.

HourSums is free to use. The calculators are informational tools and are not payroll, tax or legal advice.
