Measure how effectively offered overtime opportunities turn into confirmed employee commitments. Use the result to compare staffing windows, spot an acceptance shortfall, and estimate how many additional offers may be needed to fill the remaining shifts.
Conversion rate = accepted opportunities ÷ offered opportunities × 100
The rate shows the share of overtime opportunities that employees accepted. The gap and required-offer estimate translate the percentage into a staffing action.
Count offers and acceptances over the same period and at the same level—for example, shift offers rather than individual messages.
With 120 opportunities offered and 84 accepted, the conversion rate is 70%. There are 16 shifts left to fill, and at the same rate about 23 additional offers are needed.
No. Count the underlying opportunity once unless it is genuinely offered to a different eligible employee.
No. The calculator rejects that input because every acceptance must correspond to an offered opportunity.
The remaining target is divided by the current conversion rate and rounded up to a whole offer.
A conversion rate cannot be calculated with zero offers; enter at least one offered opportunity.
No. This measures commitments, not attendance. Track completed shifts separately if cancellations matter.
