Is Your Employer Shorting Your Paycheck? How to Check Your Time Card Math
Wage theft costs American workers $15 billion annually — more than all burglaries, robberies, and vehicle thefts combined. Most victims never realize it.
The Department of Labor estimates that 2 out of 3 low-wage workers experience at least one pay violation per week. But wage theft is not limited to minimum wage jobs — salaried employees misclassified as exempt, workers denied overtime, and time card rounding that consistently favors the employer affect millions across every income level. Checking your own math is the single most effective protection.
The Three Most Common Time Card Violations
Rounding abuse is the most widespread because it is the hardest to detect. Federal law allows employers to round time to the nearest 5, 6, or 15 minutes, but the rounding must be neutral — over time, it should average out roughly equally between employer and employee benefit. In practice, many systems round clock-in times up (7:53 becomes 8:00) and clock-out times down (5:07 becomes 5:00). Each instance shaves 7-14 minutes. Over a year of daily shifts, that adds up to 30-60 hours of unpaid work — worth $540-1,800 at $18 per hour.
Auto-deducting meal breaks is the second most common violation. Many payroll systems automatically subtract 30 minutes for lunch regardless of whether the employee actually took a full, uninterrupted break. Working through lunch while having 30 minutes deducted is wage theft. If your employer uses automatic deductions, keep a record of any day you worked through your break and compare it against your pay stub.
Overtime miscalculation rounds out the top three. Some employers calculate overtime based on base pay alone, excluding shift differentials, non-discretionary bonuses, and commissions that are legally required to be included in the regular rate. If you earn a $2 per hour night shift differential and your overtime is calculated on your base rate of $20 instead of $22, every overtime hour costs you $1 in lost wages.
How to Verify Your Pay
Track your own hours independently — a simple note on your phone with clock-in and clock-out times each day takes 10 seconds and creates an indisputable record. At the end of each pay period, calculate your expected pay using our time card calculator and compare it to your actual paycheck. If the numbers differ by more than a few dollars, you have documentation to raise the issue.
For overtime verification, use our overtime calculator to confirm your rate and hours match what appears on your stub. The employer bears the legal burden of proving hours are correct — your independent records shift that burden heavily in your favor if a dispute arises.
