Frequently asked questions
How is overtime calculated?
This tool uses a simplified model: up to 40 total hours count as regular pay, and any hours above 40 are paid at 1.5× your hourly rate. Actual overtime rules vary by employer, state, and country — always verify with your payroll department.
Do overnight shifts work?
Yes. If clock-out is earlier than clock-in on the same calendar day, the calculator treats it as a next-day clock-out (e.g. 22:00 to 06:00 counts as 8 hours).
Are unpaid breaks deducted?
Yes. Enter break minutes per shift and they are subtracted from that shift's worked time before totals are calculated.
Is this an official payroll system?
No. This is a free estimation tool for quick timecard math. For legal payroll, tax withholding, or compliance, use your employer's approved system or consult a qualified professional.
Are my shift times and pay rate uploaded?
No. All calculations run 100% client-side in your browser. Your timecard entries never leave your device.
