Breakdown

Formula: successful = started × success %; cost = successful × $0.05 (charged only on successful verifications — not failed, expired or uncompleted) + for SMS: started × attempts × $0.0083 per US SMS attempt (always charged, including resends, even if the verification fails). Push and TOTP: channel fee included in the $0.05. Voice and Email: $0.05 here, with voice/email usage billed separately on those products (not modeled). WhatsApp is omitted because Twilio's official page lists conflicting rates ($0.0034 in the channel table vs $0.0147 in the FAQ). Example: 20,000 started × 1.3 attempts × 90% → 18,000 × $0.05 + 26,000 × $0.0083 = $900 + $215.80 = $1,115.80. Carrier passthrough fees may apply on SMS attempts — see the Twilio SMS calculator.

Estimates only. Official list prices as of 2026-11-02 (Asia/Shanghai); the provider's pricing page prevails. Sources: Twilio Verify pricing
