What are Clerk's published prices?
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. |

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 and Clerk alternatives.
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?
Clerk's published Hobby (free) plan includes up to 50,000 monthly retained users (MRUs) per app. Pro is $25/month ($20 billed annually) with 50,000 MRUs included, then $0.02 per additional MRU with volume discounts down to $0.012 at 10M+. Business is $300/month ($250 annually). Figures as published July 2026 — verify with Clerk.
What is a monthly retained user (MRU)?
Clerk bills on monthly retained users rather than raw MAUs — broadly, users who return in a given month rather than every account that ever signed up. This tends to bill lower than classic MAU pricing for apps with big but lightly-active user bases. Confirm the exact counting definition with Clerk before modeling.
What does Clerk's B2B / organizations feature cost?
B2B Authentication is a published add-on at $100/month ($85 billed annually) including 100 monthly retained organizations (MROs) per app, then $1 per additional MRO, as of July 2026. Enterprise SSO connections are published at $75/month each for 2–15 connections, declining to $15 at 500+.
When does Clerk get expensive?
Two patterns: consumer apps that blow through the included MRUs (at $0.02, one million retained users is ~$20k/month before volume discounts), and B2B SaaS with many enterprise SSO connections (each connection is its own monthly line). At those points compare against WorkOS, Auth0, and open-source options.
