Your MAU, MFA, and SSO count in — your bill out.

SSO users: Amazon Cognito, Supabase Auth and Firebase Auth / Identity Platform bill SAML/OIDC per SSO user, not per connection (first 50 free, then $0.015 per SSO user a month). Their SSO results here assume 200 SSO users per connection (5 connections = 1,000 SSO users). See how 1,000 or 2,000 per connection changes the result or set your own. B2B: every SSO result assumes 1 customer organization per SSO connection (members = its SSO users, 200 by default). Published org caps and fees are applied, e.g. Clerk’s $100/mo B2B Authentication add-on above 20 members or 100 orgs, Auth0 Free’s 5-org cap, Descope $1/tenant over 35; plans over a cap are left out. All org terms · set your org count.

MFA adds a fee only when the vendor publishes one (e.g. Logto $48/mo). Plans that publish “no MFA” are omitted when MFA is required — we never invent an MFA price.

SCIM column: SCIM / Directory Sync fees for the SSO customers that need it (assumes every SCIM customer is also an SSO customer): WorkOS and Clerk bill it as a separate connection (Clerk from 2027-01-01), Stytch shares its 5 included connections between SSO and SCIM, Auth0 (Free and B2B) and Descope Growth include it. Plans without a published SCIM price drop out when SCIM > 0. SCIM by vendor.

Orgs column: B2B organization / tenant fees where published (Clerk B2B Authentication add-on + per-MRO bands, Descope and Kinde per-tenant fees, Logto Organizations add-on); plans over a published org cap are left out. Excludes SMS, custom domains, M2M token overages, taxes and negotiated discounts. Plans that cannot price the scenario (e.g. Auth0 above its top published MAU tier — 50k B2C, 20k B2B — which is Enterprise / contact sales) are omitted. How we calculate this.
