How to calculate a time card
The basic formula is straightforward: end time minus start time minus unpaid breaks equals daily hours. Summed across the week, that gives total hours worked. Where most people get tripped up is overnight shifts (work that crosses midnight), unpaid versus paid breaks, and overtime thresholds.
For US-based hourly workers under FLSA, overtime kicks in over 40 hours in a single workweek and pays 1.5x the regular rate. California adds a daily 8-hour threshold and a double-time tier over 12 hours. Adjust the threshold and multiplier above to match your jurisdiction.
Manual time cards vs continuous time tracking
Manual time cards (start time, end time, break) work for predictable schedules. They break down for freelancers who jump between projects: you cannot tell which hours belonged to which client from a single daily block. A continuous time tracker — one that runs on the task you are working on — gives per-project hours automatically. That is what Flowly does, with one-click timers on every task and a weekly timesheet view that mirrors the layout above.
