Twilio SMS Cost Calculator — Base Rate + Carrier Surcharges
Twilio's US SMS base rate is $0.0083 per message for the long-code examples shown in its current pricing table. Carrier surcharges are added on top and vary by destination carrier. Choose a carrier to estimate the all-in cost, then verify the live table before budgeting a campaign.
Current base rate
Uses the $0.0083/message US base rate currently shown in Twilio's pricing documentation.
Carrier-specific estimate
Choose AT&T, T-Mobile, Verizon, or other carriers instead of hiding the surcharge behind one average.
Transparent assumptions
The calculator separates Twilio's base charge from carrier fees and links to the official source.
Worked example: 10,000 US long-code messages
At the $0.0083 base rate, 10,000 messages cost $83 before carrier fees. With AT&T selected, the modeled $0.0035 surcharge adds $35. Registration, phone-number, failed-message, and international charges are outside this example.
Planning estimate: $118 total, or $0.0118 per message, before non-message charges.
How to use this estimate
- 1
Choose the carrier
Select the destination carrier that best matches your US traffic instead of using a blended average.
- 2
Enter message volume
Use the number of message segments you expect to send; long messages can count as multiple segments.
- 3
Separate fixed costs
Keep registration, campaign, number, and compliance fees in a separate budget line.
What can change the result
Carrier and sender type
A2P 10DLC, toll-free, short code, and international SMS can use different pricing tables.
Message segments
Unicode characters and long copy can turn one visible message into multiple billable segments.
Scale changes the decision
At high volume, a small per-message surcharge can matter more than the headline base rate.
Rates, registration fees, failed-message fees, and international prices can change. Treat the result as a planning estimate and confirm the current Twilio table before sending at scale.
Methodology & sources
This is an independent estimate. The calculator applies the rates shown in its breakdown; platform contracts, country, account tier, taxes, and promotions can change the final amount. Confirm the current terms before making a financial decision.
Rates and platform terms can change. Use the linked official source when available and verify the current terms before transacting.
