Know what a WhatsApp broadcast costs before you hit send

The most reliable way to cut broadcast spend is not a cheaper rate — it is a smaller, sharper audience. A blast to your entire contact list pays full price for thousands of people who were never going to act, while a segmented send to contacts who browsed a category, abandoned a cart or bought from you in the last quarter costs a fraction and typically converts far better. Before pricing a broadcast in this calculator, ask which segment actually needs this message — the answer is almost never "everyone".

Suppression lists matter as much as segments. Exclude contacts who purchased in the last few days from promotional sends: they have already converted, the message reads as noise, and every block or report they file counts against you. The same goes for contacts who have ignored your last several campaigns — industry reports suggest re-engaging dormant contacts with a targeted win-back message works better than including them in every routine broadcast.

Frequency matters because WhatsApp tracks how recipients react to your messages through a quality rating. When too many people block or report a sender, that rating drops, and a sustained drop can limit how many business-initiated conversations you can open per day. In other words, over-broadcasting does not just waste this month's budget — it can cap next month's reach. Sensible frequency caps protect the asset that makes broadcasts worth anything: deliverability.

• Cap promotional broadcasts per contact — many teams settle on one or two a week, adjusted by engagement.
• Suppress recent purchasers and repeatedly unresponsive contacts from marketing sends.
• Prefer utility templates for transactional updates — they are billed at a much lower rate than marketing templates.
• Invite a reply where you can: follow-ups inside the 24-hour service window need no template and cost ₹0.145 each in India, still well under a marketing template.

Run a few scenarios in the calculator above — full list versus a 20% segment, marketing versus utility — and the economics usually speak for themselves. The cost per delivered message is the figure to watch when comparing WhatsApp against SMS or email for the same campaign.

One more variable now applies to marketing broadcasts. Meta's max price, in beta, is a ceiling on what Meta charges for each delivered marketing message sent through its Marketing Messages API. It caps the charge per delivery, not the total for a broadcast. It is available in beta through InfiQ, but InfiQ billing for max-price messages is to be announced, so this calculator keeps a single per-message figure for sends without a max price. How max price works.
