Time Card Calculator
Adjust the inputs below. Results update as you type.
How it works
Enter each day's start and end times; the calculator sums regular and overtime hours. Federal overtime (FLSA): 1.5× for hours over 40/week. Some states (California) require daily overtime (over 8 hours/day). Lunch breaks are typically unpaid and deducted automatically. For hourly workers, ensure the employer's rounding policy (nearest 15 minutes is common) matches what you see on your paycheck.
Input guidance
- Confirm date/time/unit settings before comparing outputs.
- If a task has optional fields, run both with and without them to understand impact.
- Save scenario variants when making practical decisions.
The formula
Daily hours = clock-out − clock-in − unpaid break. Weekly pay = Σ daily hours × rate, with hours over 40 typically paid at 1.5× (overtime).
Worked example
Working 8.5 hours daily for 5 days is 42.5 hours: 40 at regular rate plus 2.5 at 1.5× overtime.
More examples to test
- Quick-pass example: run default assumptions for a first estimate.
- Refined example: update one assumption at a time to isolate impact.
How to interpret results
Use outputs as operational estimates and pair them with local constraints, business rules, or provider requirements.
When this can be inaccurate
Utilities can miss local policy details, special-case rules, and environment-specific constraints.

Frequently asked questions
How is overtime calculated?+
In the US, hours over 40 in a week are usually paid at 1.5 times the regular rate. The calculator separates regular and overtime hours.
Should breaks be deducted?+
Unpaid meal breaks are subtracted from worked time; paid short breaks are not. Follow your employer's and local rules.
How do I total a week?+
Add each day's worked hours, then apply the rate, splitting any hours beyond 40 into the overtime rate.
Why are outputs slightly different from another tool?+
Different tools can use different rounding rules, default assumptions, and treatment of edge cases.
How can I improve estimate reliability?+
Use verified inputs from real records and re-run calculations after major assumption changes.
