How to calculate work hours

Hours worked = (clock-out − clock-in) − break. Example: in at 08:00, out at 17:00, 1-hour lunch from 12:00 to 13:00. That's 9 hours from in to out, minus a 1-hour break: 8 hours worked.

For decimal hours (payroll or billing), divide minutes by 60: 8:15 = 8.25 h; 7:20 = 7.33 h. For pay, multiply decimal hours by your rate: 7:20 (7.33 h) × $30 = $220.00.

Balance compares what you worked with the daily hours you entered for each filled day. A positive balance might mean overtime or comp time. How your employer treats it depends on your contract and local law.

Overtime and breaks

Daily limits, break rules and overtime pay differ by country, state and employer. This tool only adds up the hours you enter. It doesn't apply legal rules or premiums. Check your contract and local rules before using the balance for pay decisions.

For information only. Not a substitute for your employer’s time system, payroll, or legal advice.

Frequently asked questions

How do I calculate hours worked?

Subtract clock-in from clock-out and deduct breaks. Sum the days for weekly or monthly totals.

How do I convert hours and minutes to decimal hours?

Divide minutes by 60 and add to hours: 7h30 = 7.5 h.

How does “shift balance” work?

For each day you fill in, we subtract your scheduled daily hours (top of the form) from the hours worked that day, then add up the differences. Positive means you worked more than scheduled; negative means less. It is only math: overtime eligibility and pay rates depend on where you work.

Should I include lunch in my hours?

Usually not. Unpaid meal breaks go in the break fields or the minutes column, so they are deducted from clock-in to clock-out. If your employer pays for breaks, leave them out of the break fields and follow your company's policy.

What if the shift crosses midnight?

Enter in 22:00 and out 06:00: the calculator treats out as the next day. Night shift differentials aren't included.
