Clerk prices on monthly retained users (MRUs) with feature add-ons layered on top. The table below summarizes the published structure as of July 2026; exact figures change, so treat these as budgeting anchors, not quotes. Plan / add-on Published price\* What to know Hobby (free) $0 Up to 50,000 monthly retained users (MRUs) per app. Pro $25/mo ($20 annual) 50,000 MRUs included; $0.02 per additional MRU, volume-discounted to $0.012 at 10M+. Business $300/mo ($250 annual) Same MRU overage structure as Pro; adds business-tier features. Enterprise custom (annual only) Quote-based. B2B Authentication (add-on) $100/mo ($85 annual) 100 monthly retained organizations included, then $1 per additional MRO. Enterprise SSO connections $75/mo each (2–15) Published sliding scale down to $15/mo each at 500+ connections. Administration (add-on) $100/mo ($85 annual) Unlimited user impersonations. Billing (add-on) 0.7% of billing volume On top of Stripe's own processing fees. \*As published by Clerk (July 2026) — verify with the vendor. Annual billing discounts apply to base plans and add-ons. ## What does Clerk cost at realistic scale? The 50,000-MRU free tier is one of the most generous entry points in CIAM — many seed-stage products never pay Clerk anything for core auth. On Pro, a consumer app retaining 200,000 users/month lands around $3,025/month at published rates ($25 base + 150,000 × $0.02) before volume discounts. For B2B SaaS the bill shape is different: the $100/month organizations add-on plus per-connection enterprise SSO fees ($75/month each at low volume) means each enterprise customer you close carries its own identity line item — price that into your enterprise tier. At high connection counts, compare against [WorkOS-style per-connection pricing](/alternatives/workos) and [Clerk alternatives](/alternatives/clerk). ## What are the pricing gotchas? - **MRU is not MAU:** retained-user counting usually bills lower than raw MAU, but the definition matters for spiky or seasonal apps — confirm how Clerk counts before extrapolating. - **B2B is an add-on, not a tier:** organizations/MRO billing ($100/mo published) plus per-connection enterprise SSO fees stack on top of Pro or Business. - **Per-connection SSO fees scale with sales:** every enterprise customer needing SAML/OIDC federation adds a published $75/month (at low volume) — great margin math for Clerk, so negotiate volume early. - **Billing add-on takes a percentage:** the 0.7%-of-volume billing feature is convenient but compounds with Stripe fees; high-volume products should compare a direct Stripe integration. ## Frequently asked questions ### How much does Clerk cost?
