We designed these plans around what actually drives lead generation results, drawing on the interactive-content patterns proven by Stripe, Typeform, and HubSpot. The Growth plan unlocks the features, white-labelling, CRM webhooks, and A/B testing, that convert casual visitors into qualified leads.
Interactive tools convert 15-30% of engaged visitors compared to 2-4% for static forms, according to Demand Gen Report data. The jump from Free to Starter unlocks the branding, integrations, and lead volume that make that conversion gap actionable.

Frequently asked questions
What is CalcStack pricing?
CalcStack pricing starts with a free plan that includes up to 10 leads per month and 3 tools. Paid plans are priced by leads captured: $39/mo for 1,000 leads with CRM integration, scaling to $79/mo for 10,000 leads with white-label branding and A/B testing. Agency plans offer unlimited leads and tools for client deployments. All paid plans include a 14-day free trial.
Can I try CalcStack for free?
Absolutely. The Free plan gives you lead capture for up to 10 leads per month, 3 interactive tools with 2,000 views per month, and basic analytics, all with no credit card required. Choose from hundreds of calculators, scorecards, decision engines, benchmarks, graders, and quizzes. Upgrade any time.
What happens if I hit my view limit?
Your embedded tools will be paused until the next billing cycle. Upgrade your plan to restore them instantly and get more monthly views. Free now ships with 2,000 monthly views (up from 500), so for most embeds the binding constraint is the lead cap below, not views.
What happens if I hit my Free lead cap?
Leads keep getting captured, but the new ones beyond 10 in the current month are locked in the dashboard. The visitor still completes the tool, the lead is still recorded, and the details (email, inputs, results) unlock as soon as you upgrade. Nothing is lost; the cap drives the upgrade conversation, not a hard stop.
Can I switch plans later?
Yes. You can upgrade, downgrade, or cancel at any time. Changes take effect at the start of your next billing period.
Which integrations are included on each plan?
Starter includes Zapier integration so you can push leads to any CRM or tool. Growth and Agency plans add direct integrations with HubSpot, Mailchimp, Salesforce, Slack, and custom webhooks. Free captures leads to your CalcStack dashboard; CRM routing turns on at Starter.
What does "white-label" mean?
On Growth and Agency plans, all CalcStack branding is removed from your embedded content. Calculators, scorecards, graders, quizzes, all look like a native part of your website.
Do you offer annual billing?
Yes, save 17% by switching to yearly billing. Toggle the switch at the top of this page to see annual prices.
What payment methods do you accept?
We accept all major credit cards via Stripe. Agency customers can also pay via invoice.
Is there a free trial for paid plans?
Yes. Starter and Growth plans include a 14-day free trial so you can test every feature before committing.
What's included in Priority Support?
Agency plan customers get a dedicated account manager, sub-2-hour response times during business hours, and onboarding assistance.
Every CalcStack tool embedded on your website captures leads automatically, visitor inputs, results, and buying signals sent straight to your CRM.
