What EarnTrace is for
EarnTrace is a local-first iPhone app and a set of free browser tools for organizing work blocks, unpaid breaks, jobs, rates, pay periods, and personal gross-pay estimates. The intended result is a clearer personal record—not a replacement for an employer timecard, pay statement, tax calculation, or qualified legal advice.
How the calculator works
The web calculator converts clock times to integer minutes, carries an earlier clock-out into the next day for overnight work, subtracts the unpaid break you enter, and totals the remaining paid minutes. When every shift has a rate, it estimates gross pay for each job before reconciling the displayed period total.
Optional overtime is a scenario tool. It allocates time chronologically within the selected workweek using the threshold and multiplier you choose. It stays off by default because eligibility, workweek definitions, state rules, agreements, premiums, and payroll rounding can differ.
Calculator inputs remain in the current browser session and are not submitted to EarnTrace. See the Privacy Policy for the full data explanation.
Editorial principles
- Answer the practical question first, then explain the math.
- Keep minute-level source time intact and round only for display.
- Separate personal estimates from payroll, tax, and legal conclusions.
- Use official sources for claims about US federal rules and definitions.
- State uncertainty plainly when rules can vary by worker or location.
- Review every guide for clarity, internal consistency, and calculator alignment.
Sources, updates, and corrections
Guides link directly to relevant official material when they discuss a US federal definition or rule. The current library uses resources from the US Department of Labor and the Internal Revenue Service where applicable. A source link supports the specific statement around it; it does not turn a general calculator into advice for an individual case.
Each guide displays its latest review date. If a calculation example, link, or explanation needs correction, use the channel listed on the Support page.
