Formula Used
Gross Hours = End Time − Start Time
Net Hours = Gross Hours − (Break Minutes ÷ 60)
Billable Hours = Net Hours × (Billable Percentage ÷ 100)
Focus Hours = Net Hours × (Productive Focus Percentage ÷ 100)
Daily Earnings = Billable Hours × Hourly Rate
Weekly Hours = Net Hours × Days Worked Per Week
Weekly Earnings = Daily Earnings × Days Worked Per Week
Daily Overtime = max(Net Hours − Overtime Threshold, 0)
Efficiency Percentage = (Net Hours ÷ Planned Hours) × 100
Schedule Variance = Net Hours − Planned Hours
Overnight shifts are supported by adding twenty four hours when the end time is earlier than the start time.

What This Calculator Reports
Gross Hours Break Hours Net Hours Billable Hours Focus Hours Daily Earnings Weekly Hours Weekly Earnings Overtime Efficiency Schedule Variance Break RatioFAQs
1) Can this calculator handle overnight work sessions?
Yes. When the end time is earlier than the start time, the calculator treats the shift as crossing midnight and adds the next day automatically.
2) What is the difference between billable hours and focus hours?
Billable hours represent time that can be charged to a client. Focus hours represent productive deep-work time based on your selected focus percentage.
3) Why do I need planned hours per day?
Planned hours let the calculator compare actual net hours against your target. That comparison produces schedule variance and efficiency percentage.
4) How is overtime calculated here?
Daily overtime is any net working time above your chosen overtime threshold. Weekly overtime multiplies daily overtime by the number of working days.
5) Can I use this for freelancers and agency teams?
Yes. It works well for solo freelancers, agencies, consultants, support teams, and anyone who tracks billable time, utilization, and earnings.
6) What does schedule variance tell me?
Schedule variance shows whether your net hours were above or below your planned daily hours. Positive values mean extra time worked. Negative values mean you fell short.
7) What is the break ratio metric?
Break ratio measures break hours as a percentage of gross hours. It helps you review how much of a session was spent away from active work.
8) Do the export buttons save the graph too?
The CSV export saves the result values. The PDF export saves a formatted summary table. The graph remains visible on the page for review.
