What this specific question is asking
Most wrong answers here are setup errors, not math errors. Confirm start time, end time, break (minutes) and hourly rate (optional) — units, periods and definitions — before you touch Time Card Calculator, and keep the output's unit attached when you use it.
A fast validation: take the worked example (As a worked reference for “How to calculate my time card”, Worked…), swap in your own start time, and confirm the result shifts in the direction the relationship predicts. If it moves the wrong way, recheck the units before the math.
Inputs to verify
- Verify start time before calculation; if this value uses a different unit, period or definition, convert or restate it first.
- Verify end time before calculation; if this value uses a different unit, period or definition, convert or restate it first.
- Verify break (minutes) before calculation; if this value uses a different unit, period or definition, convert or restate it first.
- Verify hourly rate (optional) before calculation; if this value uses a different unit, period or definition, convert or restate it first.
Step-by-step check
- Enter the clock-in and clock-out times.
- Enter the unpaid break in minutes.
- Optionally enter your hourly rate.

Worked example and sanity check
As a worked reference for “How to calculate my time card”, Worked example Clocking in at 09:00 and out at 17:30 with a 30-minute break = 8 h 30 min − 30 min = 8 hours worked.
Interpreting the result
So what does the number mean? In the worked example the calculation produced 8 h 30 min − 30 min = 8 hours worked. A result in that range is plausible for this kind of input; if your result lands far from it, revisit start time first — it is the input most often entered on the wrong basis. Read the magnitude before the decimals: a result ten times too large or small almost always means a unit or period slipped, not that the formula failed.
