Where the numbers come from
The maths is the same as the calculator on the site, with nothing hidden: total = subscription + (marketing messages × marketing rate) + (utility messages × utility rate), at the rate of the market where the person receiving the message is, not where your company is registered. With the defaults — North America, 3 agents, 3,000 marketing and 1,000 utility messages — Meta charges $78.4 a month and the cheapest option lands at $93.4 with Chatwoot.
Meta's rates come from its own pricing documentation, verified on September 8, 2026; platform prices from each vendor's official pricing page, checked on August 30, 2026. The plan used is the cheapest one that actually includes WhatsApp, with minimum seats and mandatory add-ons priced in, which is where most published comparisons go wrong.
Why this is better for you, not just for us
A price table pasted into an article ages: three months from now it will be lying to your reader and you will not know. The widget is served from here, so when Meta moves its rates your page already shows the new number. The case in front of us: on October 1, 2026 Meta starts charging for replies sent inside the 24-hour window, and the last column already prices the same month under the new rule. If you have ever written about WhatsApp pricing, that article goes stale that day.
Frequently asked questions
What does it cost to use the calculator on my site?
Nothing, and there is no paid tier or account to create. All we ask is that the link to quetecuesta.com stays visible: it already sits in the widget footer and in the credit paragraph, so your reader can see where the numbers come from and check them.
Does it set cookies or track my readers?
It sets no cookies and stores nothing in your reader’s browser. The widget loads Vercel’s cookieless, anonymous pageview counter, the same one the rest of the site uses, which is the only way we know whether anyone is using it. There are no third-party pixels, no ads and no affiliate links inside the widget.
Do the numbers update on their own?
Yes. The widget is served from quetecuesta.com, so when Meta’s rate card or a platform’s price changes, your page shows the new figure without you touching it. That matters right now: on October 1, 2026 Meta starts billing replies sent inside the 24-hour window, and the “From Oct 1” column already prices it.
Where do the rates come from?
Meta’s own pricing documentation, verified on September 8, 2026, and each vendor’s official pricing page, checked on August 30, 2026. The table is ordered by total cost and by nothing else. Some platforms pay us a commission if someone signs up through our link, but those links live on our site, never inside the widget you embed.
Can I change the size or the language?
The suggested height is 860 pixels, which is enough on narrow screens; in a wide column you can drop it to about 700. The widget adapts to whatever width you give it and follows the reader’s dark mode. Two languages: /widget/calculator in English and /widget/calculadora in Spanish.
