SMS vs WhatsApp vs Voice Cost Calculator
Enter your monthly message volume for each channel and see an estimated cost comparison, including cost per lead if you know your conversion numbers.
Why compare cost across channels, not just per-message price
SMS almost always looks cheapest per message, but it isn't always the cheapest way to hit a business outcome. WhatsApp Business API costs more per conversation but supports two-way replies and rich media, which can lift response and conversion rates enough to lower your effective cost per lead. Voice sits in between, with a higher cost per contact but often the highest-trust channel for time-critical or high-value outreach.
How to use this calculator
Enter your typical monthly volume and rate for each channel you use. If you know how many leads or conversions came from that volume, add it in the optional field to see a blended cost-per-lead figure across all three channels combined. Adjust the rate fields to match your actual pricing for a more accurate comparison.

WhatsApp Business API pricing is typically conversation-based and includes richer media and two-way messaging capability, which SMS does not offer. The right channel depends on the use case, not just the per-message price.
Not necessarily. OTPs and time-critical alerts often perform best on SMS regardless of cost, while WhatsApp can lift conversion on marketing and support conversations enough to offset the higher per-message rate. Compare cost per lead or per outcome, not just cost per message.
