Erlang C & Erlang A calculator
FreeAgents required, service level, ASA, occupancy, abandons, shrinkage and shareable links.
Patreon
The calculator stays free for everyone. The Fratz WFM tier ($6.99/month) unlocks the tools for planning a real day: interval planning, your own ACD data, what-if analysis and more. All Access adds Fratz QA and every other Fratz Contact Center Tool, with no team-size limit.
Either tier unlocks everything on Fratz WFM. Join on Patreon, come back here, and log in with Patreon. Looking for Fratz QA only? See all tiers.
Test mode Join buttons open a test dialog instead of Patreon. No payment is taken.

Free features stay free. Fratz WFM features unlock with the Fratz WFM or All Access tier, wherever you log in with Patreon.
Agents required, service level, ASA, occupancy, abandons, shrinkage and shareable links.
Paste or upload a full day of interval volumes and staff every interval at once, with FTE and schedule hours.
Bring in historical CSV or Excel exports and turn them into interval volumes and handle times.
Move volume, AHT and shrinkage and see staffing and service level change against your baseline.
Itemize breaks, meetings, coaching, PTO and absence into one shrinkage figure. Open it from the Shrinkage field.
Staff chat queues where agents handle several conversations at once (an approximation).
Save named scenarios, and export them all to a file to back up or move to another device.
Join the Fratz WFM tier (or All Access) on Patreon. Then come back to Fratz WFM and click Log in with Patreon. Patreon confirms your tier and its features unlock in that browser. On another device, just log in with Patreon there too.
Patreon does. Payments, receipts, sales tax and VAT, changing tiers, cancelling and refunds are all handled on Patreon under Patreon's policies. Memberships are billed and refunded by Patreon under its own policies. To change or cancel, use your Patreon memberships page.
Fratz WFM ($6.99/month) unlocks every Fratz WFM feature for teams up to 15 agents. Fratz QA ($9.99/month) is the QA tool only. All Access ($19.99/month) unlocks both, the All Access-only tools, and removes the 15-agent limit. You're in one tier at a time; switch tiers on Patreon.
Only what Patreon shares when you log in: your Patreon user ID, first name, membership tier and whether the membership is active. We don't receive your email address or card details, and we don't keep a database of supporters. A secure, encrypted cookie in your browser keeps you logged in for about 30 days.
No. All calculations, imports and scenarios stay in your browser. See the privacy page.
Patreon can take a minute to confirm a new membership. Log out, then log in with Patreon again. Make sure you log in with the same Patreon account you joined with. Still stuck? Email CONTACT_EMAIL_TBD.
