Clerk bills Monthly Retained Users (MRU), not MAU: a user counts only if they come back at least one day after signing up ("First Day Free"). MRU = users × retained %. Pro $25/mo ($20 annual), Business $300/mo ($250 annual), both with 50,000 MRU included; then per MRU/mo: 50,001–100k $0.02, 100,001–1M $0.018, 1M–10M $0.015, 10M+ $0.012. Hobby is free up to 50,000 MRU per app (upgrade required above). SSO connections: 1 included, 2–15 $75/mo each, 16–100 $60, 101–250 $48, 251+ contact sales. Directory Sync uses the same tiers but billing starts 2027-01-01 (off by default; projected cost shown). B2B add-on $100/mo ($85 annual) with 100 MRO included, then 101–1,000 $1, 1,001–10k $0.90, 10,001–100k $0.75, 100k+ $0.60. SMS $0.01 (US/CA), satellite domain $10/mo, Protect 10k checks free then $0.002. Example: 200k users × 60% = 120k MRU → $25 + 50k × $0.02 + 20k × $0.018 ($1,360) + 9 × $75 SSO ($675) = $2,060/mo.

How it works
- How much does Clerk cost in 2026?
- Hobby is free up to 50,000 MRU per app. Pro is $25/mo ($20 billed annually) and Business $300/mo ($250 annually), each with 50,000 MRU included, then $0.02 per MRU up to 100k, $0.018 to 1M, $0.015 to 10M and $0.012 above (as of 2026-11-02).
- What is an MRU?
- A Monthly Retained User is a user who visits your app in a given month at least one day after signing up. Users who sign up and never return after day one are free ("First Day Free"), so MRU is usually well below MAU.
- What is a worked example?
- 200,000 monthly users × 60% retained = 120,000 MRU on Pro: $25 + 50,000 × $0.02 + 20,000 × $0.018 = $1,385, plus 10 SSO connections (1 included, 9 × $75 = $675) → about $2,060 per month.
- How are SSO and Directory Sync priced?
- One enterprise SSO connection is included; connections 2–15 cost $75/mo each, 16–100 $60, 101–250 $48, 251+ contact sales. Directory Sync uses the same tiers, but Clerk starts billing it on 2027-01-01.
- What does the B2B add-on cost?
- $100/mo ($85 annually) with 100 monthly retained organizations included, then $1 each for 101–1,000, $0.90 to 10,000, $0.75 to 100,000 and $0.60 above.
