What is your provider's markup actually costing you?

Most WhatsApp Business API providers bill you Meta's per-message charge plus their own margin — usually 15–25%, billed through their platform so you never see the split. Enter your monthly message volume below to see the two halves separately. Nothing is stored, and you don't need an account.

Destination market Rates differ by country. We only list markets we hold a rate card for.

Marketing messages Broadcasts, offers, re-engagement.

Utility messages Order updates, reminders, receipts.

Authentication messages OTPs and verification codes.

Assumed provider markup 20%

Slide this to match what you believe your provider adds. We default to 20% — the middle of the range typical resellers charge. If you know your real figure, use it.

Why Klaros can't mark this up even if we wanted to.

You connect your own WhatsApp Business Account and your own Meta billing. Meta charges you directly; we are never in the payment path. That isn't a pricing promise we could revise later — it's a consequence of the architecture. We charge a flat licence and nothing per message. See pricing →

How this is calculated

Meta bills per message, at a rate that depends on the destination country and the category of the message. We multiply your volume by Meta's published rate for the market you picked, then apply the markup percentage you selected to show what a reseller would add on top. Service messages — the replies your customers start — are free under current pricing, so they're not billed here.

These rates were derived from real WhatsApp billing, not a published list — but they are still an estimate, not a quote. Your own invoice depends on your exact message mix and any agreement you hold with Meta. Once you're sending through Klaros, the in-app cost dashboard replaces this estimate with your real billed figures — computed by the same code that produced the numbers above.
