How do I add up a weekly time card?

Calculate daily hours by subtracting start time from end time and deducting unpaid breaks. Convert each day to decimal hours, then sum the seven days. Hours above 40 are usually overtime under federal law.

Are lunch breaks paid or unpaid?

Meal breaks of 30 minutes or more are typically unpaid under federal rules when the employee is fully relieved of duty. Short rest breaks under 20 minutes are usually paid. State and employer rules can be stricter.

Timesheet Calculators

Track daily and weekly hours with lunch breaks, overtime, and shift support.

Time cards are the foundation of hourly payroll. These tools handle everything from a single shift to a full biweekly timesheet, including overnight shifts and lunch deductions.

How timesheet calculators work

Each tool follows the same arithmetic a payroll clerk would use on paper: end time minus start time, minus unpaid breaks, converted to decimal hours by dividing minutes by 60. Daily totals roll up to a weekly or biweekly summary, and overtime is flagged once a configurable threshold (usually 40 hours per week) is crossed.

When to use each tool

Time card calculator: one or more shifts in a single day.
Time card with lunch break: built-in unpaid lunch deduction.
Weekly timesheet: seven-day rollup with overtime above 40 hours.
Biweekly time card: 14-day pay period used by many U.S. employers.
Night shift / shift hours: overnight shifts that cross midnight.

Limits and verification

These tools do not see your employer's time clock rounding rules, paid break policy, premium pay, or shift differentials. Treat results as quick estimates, then reconcile against your official pay stub or payroll provider report.

Frequently Asked Questions

In practice the terms are used interchangeably. A time card usually refers to a single employee's punches for a pay period, while a timesheet may cover a project or a team. Both feed payroll the same way.

Before you use the result

Our calculators give quick payroll-time and pay estimates. Your final paycheck depends on factors this tool does not see, including employer policy, state and local rules, time clock rounding, paid versus unpaid breaks, premium pay, deductions, and how your payroll provider applies them.

Confirm pay rules with your employer, payroll provider, or HR team.
Overtime, breaks, and rounding rules can change by state.
