Enter your start and finish times for each day, take off breaks, and this hours calculator totals the week and estimates pay — including overtime at the rate you set. Handy for timesheets, invoicing hourly work, or checking a payslip.

Converting minutes to decimal hours

Payroll systems use decimal hours: divide the minutes by 60. 7 h 30 min = 7.5 h, 8 h 15 min = 8.25 h, 6 h 40 min = 6.67 h. A quick reference: 15 min = 0.25, 30 min = 0.5, 45 min = 0.75.

Overtime

Overtime rules vary by country and contract. In the US, non-exempt employees earn 1.5× after 40 hours in a week under federal law; some states also apply daily thresholds. Set the threshold and multiplier to match your situation. For pay across the year, see the salary calculator; for counting working days in a period, use working days.
