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.

01 ◆

Stackable's block is a single-step math widget. Multistep flows with conditional branches need a real plugin.

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.
