Direct answer
Use the paid start time that payroll approves. If early clock-in time was not authorized or no work was performed, the time card may need a correction to the scheduled start time.
Best fit search phrase: "calculate time card when clocked in before work started". Use the calculator after you have the source record, policy wording, schedule, contract term, or pay-stub line in front of you.
Open Time Card CalculatorReal workplace situation
A worker clocks in at 7:48 for an 8:00 shift because the time clock is near the entrance. If work actually begins at 8:00, payroll may correct the paid start time depending on policy.
Raw punch: 7:48-4:30 with 30-minute lunch = 8.20 hours. Approved paid shift: 8:00-4:30 with 30-minute lunch = 8.00 hours. Difference to explain: 0.20 hours, or 12 minutes.
Working rule
Paid time = approved work start to clock-out, minus unpaid breaks, when early clock-in was not approved as work time.

Checklist before you rely on the number
Key checks
- Keep the raw clock-in time.
- Find the scheduled or approved start time.
- Confirm whether any work happened before the start time.
- Calculate both raw and approved totals if asking payroll.
- Save the manager approval note if early work was authorized.
Practical notes
Some systems round early punches, while others require manager edits.
If the worker performed required work before the scheduled start, the answer may change.
A small early punch repeated every day can add up over a pay period.
Mistakes that change the result
Do not delete the raw punch from your notes.
Do not assume every early clock-in is paid or unpaid without policy context.
Do not forget lunch after adjusting the start time.
