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.

How it works
- How much does Twilio Verify cost in 2026?
- $0.05 per successful verification, plus channel fees. SMS adds $0.0083 per US attempt; Push and TOTP include the channel fee in the $0.05; Voice and Email are billed separately on those products (as of 2026-11-02).
- Am I charged for failed verifications?
- The $0.05 verification fee is charged only on successful verifications — not failed, expired or uncompleted ones. SMS attempts are always charged, including resends, even if the user never completes.
- What is a worked example?
- 20,000 started × 1.3 SMS attempts × 90% success → 18,000 × $0.05 + 26,000 × $0.0083 = $900 + $215.80 = $1,115.80 per month, about $0.062 per successful signup, before carrier fees.
- Do carrier fees apply to Verify SMS?
- Carrier passthrough fees may apply on top of SMS attempts. Use the Twilio SMS cost calculator to estimate AT&T, T-Mobile and Verizon fees.
- Why is WhatsApp not in the calculator?
- Twilio's official Verify page lists two different WhatsApp rates ($0.0034 in the channel table vs $0.0147 in the FAQ), so we omit it rather than guess.
