The service
SumHours provides free, browser-based calculators for adding up work hours. The service is provided as-is, with no warranty of any kind.
Your responsibility
You’re responsible for checking that the times, breaks and rates you enter are correct. SumHours calculates exactly what you type in — it cannot know whether that matches your actual schedule.
No advice
SumHours does not provide legal, tax or payroll advice. Nothing on this site should be treated as a substitute for advice from a qualified professional.
No guarantee against your payslip
We don’t guarantee that a calculated gross-pay figure will match an actual payslip. Deductions, tax and employer-specific rules are outside what we calculate.
Intellectual property and acceptable use
The SumHours name, branding and site content belong to SumHours. Don’t scrape, resell, or misrepresent this tool as your own. You’re welcome to link to it.
