Volunteer shift roster

Estimate staffing for daily service coverage with breaks and reserve cover.

How it is calculated

Coverage = positions × service hours. Productive time per volunteer = shift hours × (1 − nonworking fraction). People = round up(coverage ÷ productive time) + reserve.

Assumptions & limits

Availability totals do not prove a workable hour-by-hour roster. Skills, overlap, rest, safeguarding and local labor requirements need separate planning. Defaults are illustrative planning inputs, not recommended minimums or a guarantee of safety.

All tools
