Timesheet Calculator

Timesheet calculators convert clock-in and clock-out times into total hours worked, accounting for breaks and overtime. A typical entry — clock in at 8:47 AM, lunch break 12:00-12:45 PM, clock out at 5:23 PM — totals 7 hours and 51 minutes of work time, or 7.85 hours in decimal format (commonly used for payroll). Overtime calculation follows labor law rules: in the US, the Fair Labor Standards Act mandates 1.5x pay for hours exceeding 40 per week. Some states (like California) also require daily overtime — 1.5x after 8 hours and 2x after 12 hours in a single day. A worker earning $25/hour who works 45 hours in a week earns $1,000 for the first 40 hours plus $187.50 for 5 overtime hours = $1,187.50. This calculator handles weekly totals, daily overtime rules, and custom break deductions. Rounding rules matter too: many employers round to the nearest 15 minutes, so 8:07 rounds to 8:00 and 8:08 rounds to 8:15. All your work hours stay private in your browser.

For freelancers and small business owners, accurate timesheets are essential for client billing and project profitability. A common approach is tracking time by project and task: 3.5 hours on Project A design, 2.25 hours on Project B development, 1.5 hours on admin. At a billing rate of $85/hour, Project A generates $297.50 in revenue for that day. Comparing billable hours (client work) against total hours worked gives your utilization rate — the industry standard target is 65-75% for consultants and 80%+ for agencies. If you work 40 hours but only 28 are billable, your 70% utilization means 12 hours go unbilled (marketing, admin, meetings). To maintain your target income with lower utilization, your hourly rate must increase proportionally. This calculator helps you track daily and weekly totals, calculate overtime, and export summaries. For team managers, consistent timesheet data reveals project cost trends: if a task budgeted for 10 hours consistently takes 15, future estimates need adjustment.
