Totals, targets and your own threshold

Exact counted time

The core record uses integer minutes. For each valid shift, subtract valid unpaid breaks from the date-and-time span; paid breaks remain included. Add net shift minutes into the day and period containing each shift’s start date. A display in decimal hours is calculated from that minute total.

Drafts and errors

An unfinished or invalid shift cannot contribute a final duration. If a completed subtotal is shown, it must be labeled as such and identify records still needing attention. A saved draft is not a completed card, and a successful local save does not change that distinction.

Targets and remaining work

The target is entered by you. If completed work has reached or passed it, the result should state that condition rather than treating a negative remainder as work to perform. The clock-out tool adds remaining counted work and planned unpaid breaks to a start date and time. Paid breaks are not added again.

Regular and extra hours

An optional user threshold splits a completed total for your own comparison. At a total of 42:30 and threshold of 40:00, the split is 40:00 regular plus 02:30 extra. The tool does not choose a legal overtime rule, premium or jurisdiction.

Simple amount estimate

The optional amount estimate multiplies counted hours by your entered rate in your chosen currency. At 38.25 hours and a rate of 20.00, the result is 765.00. Taxes, premiums and payroll rules are not included. It is an arithmetic estimate, not an invoice, payment or determination of wages owed.
