How to Use a Time Card Calculator

A time card calculator converts your daily clock-in and clock-out times into total hours worked, separating regular time from overtime. Whether you're an hourly employee verifying your paycheck, a freelancer tracking billable hours, or an employer running a small business, accurate time tracking is essential.

Understanding Overtime Rules

Under the Fair Labor Standards Act (FLSA), non-exempt employees must receive overtime pay of at least 1.5 times their regular rate for hours worked over 40 in a workweek. Some states like California also require daily overtime — any hours over 8 in a single workday are paid at overtime rates, and hours over 12 are paid at double time.

Lunch Breaks & Deductions

Most employers provide a 30-minute or 1-hour unpaid lunch break. Federal law doesn't require lunch breaks, but many states do. Unpaid breaks should be deducted from your total hours. Short breaks (5–20 minutes) are generally considered paid time under the FLSA.

Split Shifts

If you work two or more separate periods in a day (e.g., morning and evening), you're working a split shift. Some states like California require extra "split shift premium" pay. This calculator supports multiple shifts per day so you can track them accurately.

Tips for Accurate Time Tracking

• Record your times daily — don't rely on memory at the end of the week
• Include all time worked, even checking emails before your shift
• Note any breaks that should be deducted
• Keep records for at least 3 years (FLSA requirement for employers)
• Use this calculator to verify your paycheck matches hours worked
