How the time card calculator works

Enter clock-in and clock-out times for each day of the week. Optionally add a break period — the break duration is subtracted from worked hours. Overtime is calculated as any hours beyond 40 per week at 1.5× the hourly rate. All data stays in your browser; nothing is sent to a server.

What this tool is used for

Totalling hours from clock-in and clock-out times across a week.
Deducting unpaid breaks from a shift total.
Working out overtime hours above a weekly or daily threshold.
Producing a pay figure from hours and an hourly rate.
Checking a timesheet total against the entries.

Frequently Asked Questions

How is a night shift that crosses midnight handled?: Correctly. When the clock-out time is earlier than the clock-in, 1,440 minutes — one day — are added rather than returning a negative span, so 22:00 to 06:00 reads as 8 hours. Naive time-card maths flattens that to zero and loses a whole shift.
Which overtime rule does it apply?: The US federal FLSA rule: hours above 40 in the week, paid at 1.5×. The threshold is weekly, so a 12-hour Monday inside a 35-hour week produces no overtime here. California's daily rule — over 8 hours in one day — is not applied.
What if the break is longer than the shift?: The day is floored at zero rather than going negative, because a break longer than the shift is a data-entry error, not negative work. Check that the break start and end are the right way round, and that they are on the correct row.
Why does a day show no hours?: Both clock-in and clock-out have to be filled for a day to count; a row with only one of them contributes zero. The break pair is optional — leave both blank for an unbroken shift, and fill both if you want it deducted.
Should I round to the nearest quarter hour?: Many US employers do, and the FLSA permits it as long as the rounding is neutral over time — it must sometimes favour the employee, never systematically the employer. This tool keeps exact minutes; round afterwards if your payroll requires it.
Should hours be recorded in decimal or minutes?: Decimal for payroll arithmetic, since 7:30 must be 7.5 rather than 7.3 before it is multiplied by a rate. Treating the minutes as a decimal fraction is a small error that recurs every entry.

Common errors and gotchas

Handling a shift that crosses midnight as a negative duration rather than wrapping.
Reading a decimal hours total as hours and minutes, where 7.5 is seven and a half hours.
Rounding each entry rather than the total, which drifts over a week.
Applying an overtime threshold daily when the rule is weekly, or the reverse.
Ignoring a daylight-saving transition, which changes one shift's length.
