Frequently asked questions
How do I calculate hours worked?
Subtract the start time from the end time and subtract unpaid breaks. Convert minutes to decimals by dividing by 60 (45 minutes = 0.75 hours).
How is overtime paid?
In many US jurisdictions hours beyond 40 a week are paid at 1.5 times the regular rate. Rules vary, so check yours.
Can it handle shifts that cross midnight?
Enter the end time as earlier than the start time and it treats the shift as running past midnight.
Is the pay figure after tax?
No, it is gross pay. Use the paycheck calculator for take-home estimates.
