WhatsApp Cost Radar 2026

A free calculator to estimate what you will pay on WhatsApp from 1 October 2026, when Meta starts charging for service messages sent outside the free 72-hour window.

What changes in October 2026

Until now, service messages — the ones replying to a customer who wrote first — were free inside the support window. Under Meta’s new scheme, those sent outside the 72-hour window carry a per-message cost, and that cost varies country by country. For a business with high support volume, the change can move the bill significantly.

What the simulator does

• Estimate your monthly cost by conversation volume and country.
• Compare spend before and after the pricing change.
• See how much each message type weighs: marketing, utility, authentication and service.
• Measure the effect of replying inside the 72-hour window.
• Download the result to share with your team.

How to bring the bill down

The biggest lever is replying inside the free window: an agent that answers in seconds, at any hour, keeps most conversations within 72 hours and avoids the per-message cost. The other two are consolidating several exchanges into a single conversation, and using Click to WhatsApp Ads, which open the support window at no template cost.
