Work Hours and Pay Calculators

These calculators cover the everyday time math behind a paycheck: hours between two clock times, a full time card with lunch breaks and overtime, adding up durations, and counting business days to a deadline.

Pick the right calculator

• Hours CalculatorWork out hours between two times, minus a lunch or break, in hours and minutes and in decimal hours.
• Time Card CalculatorAdd up a weekly or two-week time card with lunch breaks, see regular and overtime hours, and estimate gross pay.
• Time CalculatorAdd or subtract hours, minutes, and seconds. See the result as h:mm:ss, decimal hours, total minutes, and total seconds.
• Business Days CalculatorCount business days between two dates, or add business days to a date, skipping weekends and US federal holidays.
• Date DifferenceCount days between two dates.
• Percentage CalculatorFind a percentage of a number, reverse a percentage, or calculate percent change. Clear formulas show each step.

Which one should I use?

• Use the Hours Calculator for a single shift, including overnight shifts.
• Use the Time Card Calculator for a full week or a two-week pay period. It splits regular and overtime hours for each week.
• Use the Time Calculator to add or subtract durations such as 2:45 plus 1:30.
• Use the Business Days Calculator to count working days between two dates or to find a due date, skipping weekends and US federal holidays.
• Use the Percentage Calculator for a raise or a percent change in pay.

Decimal hours

Payroll systems usually want decimal hours. Divide the minutes by 60 and add them to the hours, so 7 hours 45 minutes is 7.75 hours. The Hours and Time Card calculators show both formats.
