Free Erlang C calculator. See average wait, chance of waiting, staff needed and when to stop joins. Runs offline, no data collected. Plan your line in seconds. Enter arrivals per hour, average service time and staff serving to see the average wait, the chance a guest waits and how many staff you need to hit your target wait. Three tools in one popup: Wait time: an Erlang C and queuing theory calculator (M/M/c model). Staff needed: a staffing calculator for counters, clinics, events and stores. When to stop joins: the cutoff time to close the queue so everyone is served before closing. Private by design. Everything runs on your device. No account, no sign in, no data collected, no site access. Made by ScanQueue, the QR waitlist and queue management app. Want guests to see a live wait estimate on their phone?
