The WhatsApp Reply-Cost Calculator
A Spanish-language calculator estimating what businesses may pay to answer customers through the WhatsApp Business API after October 1, 2026.
Field notes
The page models service-message costs from customer volume, country, and phone-number count, then presents three estimated usage scenarios. Its rules distinguish messages received from replies sent, limit the free allowance to 1,000 delivered responses per phone number each month, and note that unused allowance expires. The explainer also separates the 24-hour reply window from template messages used after that window closes, giving readers a practical map of which WhatsApp interactions the estimate covers.
