Inputs
Formula transparency
Source: defaultweekly = Σ dailyNet · pay = regular·rate + overtime·rate·multiplier
How to use it
- Add each day's start, end, and break.
- Set the weekly overtime threshold (often 40h).
- Add an hourly rate for a pay estimate.
Example
- Five 8.5-hour days minus breaks ≈ 37.5 weekly hours — under a 40h threshold, so no overtime.
What the result means
Weekly hours split into regular and overtime; pay applies your rate (and the overtime multiplier).
Common mistakes
- Entering 12-hour times without AM/PM context (use 24-hour).
- Forgetting to subtract breaks.
Limitations
- Labor rules and overtime vary by country and employer.
- Estimate only — not legal advice.
Frequently asked
- How is overtime computed?
- Hours above the weekly threshold (default 40) are overtime at a multiplier (default 1.5).
- How many days?
- Up to 7, each optionally named.
- Overnight shifts?
- Yes — if end is before start, we assume the next day.
- Is the pay exact?
- It's an estimate; taxes, allowances, and labor rules vary.
- Is this legal advice?
- No — an estimation tool. Check your labor law and contract.
