Frequently asked questions
Does the leave-work calculator handle overnight shifts?
Yes. The calculator shows the resulting clock time even when it wraps past midnight. If it lands earlier than your start time, read that time as the following calendar day.
How does the time-worth calculator define value per hour?
It divides your net hourly rate by the minutes or hours a task takes to give a dollar cost for that block of time. The result is a planning estimate; it does not account for taxes, benefits, or opportunity cost beyond the rate you enter.
