Two Calculation Modes

Choose between quick estimation for planning or detailed day-by-day tracking for accurate timesheets.

📊 Estimate Mode

Assumes uniform hours each day. Perfect for:

  • • Planning weekly/monthly schedules
  • • Salary negotiations
  • • Quick rough estimates

📅 Track Week Mode

Adjust each day individually. Perfect for:

  • • Recording overtime on specific days
  • • Half-days and paid leave tracking
  • • Accurate weekly timesheets

How Work Hours Are Calculated

Accurate time tracking is essential for fair compensation, project management, and work-life balance. This calculator computes your working hours at daily, weekly, and monthly levels.

Net Hours Formula

Net Hours = End Time - Start Time - Breaks

Example: 9:00 to 17:30 with 30min break = 8 hours

Overtime Formula

Overtime Pay = OT Hours × Rate × Multiplier

Example: 2h × $20 × 1.5 = $60 overtime

Common Overtime Rules

Time and a Half (1.5×)

Most common rate in the US for hours over 40/week or 8/day.

Double Time (2×)

Often applies to holidays or work beyond 12 hours in a day.

Comp Time

Some employers offer time off instead of overtime pay.

Exempt Employees

Salaried employees may not qualify for overtime premium.

Frequently Asked Questions

What's the difference between Estimate and Track modes?▼
Estimate mode calculates based on a uniform daily schedule (same hours every day). Track mode lets you adjust each day individually for overtime, half-days, paid leave, or days off.
How are net working hours calculated?▼
Net working hours = End Time - Start Time - Break Duration. For example, 9:00 AM to 5:30 PM with a 30-minute break = 8 hours net.
How do I track overtime on specific days?▼
Use Track mode and set individual days to "Custom" to enter exact hours. The calculator automatically calculates overtime based on your threshold setting.
When does overtime start?▼
This depends on your employment contract and local laws. The default is 8 hours per day, but you can adjust the threshold. In the US, overtime typically starts after 40 hours per week.
How is overtime pay calculated?▼
Overtime hours × Hourly Rate × Overtime Multiplier. For time-and-a-half (1.5x), working 2 overtime hours at $20/hour = 2 × $20 × 1.5 = $60.
How does paid leave work in Track mode?▼
Paid leave days count as full working hours for pay calculation but are marked separately. This helps track actual attendance while maintaining salary accuracy.
How are monthly hours estimated?▼
Monthly hours are calculated using an average of 4.33 weeks per month (52 weeks ÷ 12 months). This accounts for months having different numbers of days.
