Free time card and payroll calculators
Nine calculators for the arithmetic that sits between a punch clock and a paycheck. Every one runs entirely in your browser: there is no account, nothing is saved, and nothing you type is sent to us or to anyone else. Use them for a single shift, a full week, or to check a number before you approve payroll.

Add up hours
Turn clock-in and clock-out times into the decimal hours payroll actually accepts.
Time Card Calculator
Add up a week of clock-in and clock-out times, minus unpaid breaks, in decimal hours.
Reach for it when: You have a paper time card or a punch printout and need one number to hand payroll.
Open calculatorTimesheet Calculator
Total a weekly timesheet, day by day, with unpaid breaks deducted.
Reach for it when: You keep timesheets in a spreadsheet and want the week's total checked before you run payroll.
Open calculatorWork Hours Calculator
Hours worked between any two times, including shifts that run past midnight.
Reach for it when: A single shift needs checking, or an overnight shift is not adding up the way you expect.
Open calculatorTime Clock Calculator
Total punch-clock times into payroll-ready hours for the pay period.
Reach for it when: You are reconciling a punch clock's tape against what you are about to pay.
Open calculatorDecimal Hours Converter
Convert minutes to decimal hours, and back, the way payroll systems expect.
Reach for it when: Payroll wants 8.25, your notes say 8 hours 15 minutes, and the two keep drifting apart.
Open calculatorWork out pay
Convert hours and rates into gross pay, including overtime premiums.
Overtime Pay Calculator
Time-and-a-half and double-time from an hourly rate and the hours worked.
Reach for it when: Someone went over forty hours and you need the premium right before it becomes a back-pay claim.
Open calculatorSalary to Hourly Calculator
Convert an annual salary to an hourly rate, and an hourly rate back to salary.
Reach for it when: You are pricing a role, or checking whether a salaried employee clears the exempt threshold.
Open calculatorPlan ahead
Answer the scheduling and accrual questions before the pay period closes.
Clock-Out Time Calculator
Clock-in time plus the hours you owe, plus the break, equals exactly when the shift ends.
Reach for it when: Someone started late and you need to tell them when they can leave without short-changing the shift.
Open calculatorPTO Calculator
Paid time off accrual, by hours worked or from an annual award.
Reach for it when: An employee asks how much leave they have banked and you would rather not guess.
Open calculatorWhy hours and pay so rarely agree
Minutes are not decimals
Payroll wants 8.25 hours. The time card says 8 hours 15 minutes. Those are the same number written two ways, and treating 8:15 as 8.15 quietly underpays every shift that ends on a quarter hour. Divide the minutes by 60, never move the decimal point.
Overtime is weekly, not daily
Federal overtime is owed on hours past 40 in a fixed, recurring workweek, so a bi-weekly payroll still totals each of its two weeks separately. A handful of states add a daily premium on top, which is where most miscalculations start.
Unpaid breaks have to come out
A genuine, uninterrupted meal break of 30 minutes or more is generally unpaid. Short rest breaks are not: under federal rules, breaks of roughly 20 minutes or less count as hours worked and get paid, whether or not anyone clocked out for them.
Overnight shifts cross a date
A shift from 10pm to 6am is eight hours, but subtracting the clock times gives you minus sixteen. Every calculator here handles the rollover, which is the single most common reason a manual time card total comes out wrong.
The rules themselves vary by state. See overtime laws by state, meal and rest break rules, and when rounding punch times is allowed.
Stop doing this arithmetic by hand
These calculators exist because the maths is fiddly and easy to get wrong. A time clock does it continuously and keeps the record: employees punch in on a tablet or their phone, breaks and overtime are calculated as the week runs, and the total exports straight to payroll. The Kloqk time clock is free for unlimited employees, with no per-seat fee.
