Clerk Cost Calculator

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.
