Stackable's block is a single-step math widget. Multistep flows with conditional branches need a real plugin.
Stackable calculator alternative
A Stackable calculator alternative with real pricing logic.
Stackable's calculator block is a great Gutenberg-native intro to on-page calculations. For teams that need conditional pricing, CRM integration, Stripe deposit, and a PDF quote, a custom build is the next step.

The bottleneck
What slows teams down today.
02 ◆
No CRM push, no email-with-quote, no PDF output. The lead capture story is missing.
03 ◆
Pricing logic is limited to direct math. Per-tier discounts, conditional fees, multi-currency need custom code.
04 ◆
No Stripe / payment integration.

FAQ
Stackable alternative FAQs.
No fluff — the specifics buyers want before booking a call. If yours isn't here, ask on the call.
Is the Stackable calculator block bad?
Not at all — it's exactly right for what it is. Quick on-page math (mortgage, BMI, conversion). When you need lead capture + conditional pricing + integrations, it's the wrong tool, but that's a different product.
How long does the custom build take?
5 days for Lite, 10 days for Pro, 3-4 weeks for Custom. Same packages as on /calculator-lp/.
Will the custom build still work in Gutenberg?
Yes — the calculator is a custom Gutenberg block + shortcode + REST endpoint. Drops into any page or post; theme-agnostic.

Extremely patient and extremely professional. And the result is amazing! Highly recommended!

Great experience overall. The cost estimation calculator works well for our B2B needs and does exactly what we discussed. It's simple to use, and the logic behind the calculations is solid. There were a couple of small tweaks needed after delivery, but the seller was quick to respond and fixed everything.
