How this calculator works
Balance = starting balance + earned − used + adjustments.
Worked example
40 starting hours + 16 earned − 12 used = 44 hours.
How to interpret the result
Use the displayed result as a planning figure, not as an official payroll determination. A materially unexpected result usually means the entered period, rate, threshold, break, accrual rule, or conversion basis should be checked.
