Frequently Asked Questions

Do I need a CalcMountain account to use the calculators?

No. All 400+ calculators are free to use on calcmountain.com with no sign-up required. Accounts are only needed for embedding calculators on your own site, saving calculations, and downloading PDFs.

How does embedding work?

After subscribing to a paid plan, you create an embed key in your dashboard, configure your allowed domains and branding, and copy a small HTML snippet (a div + script tag). Paste it anywhere on your site and the calculator loads automatically inside a responsive iframe.

Can I customize the look of embedded calculators?

Yes. All paid plans include custom branding — set a primary color, accent color, and logo. Professional and Unlimited plans also let you remove the "Powered by CalcMountain" badge for a fully white-label experience.

Can I change or cancel my plan at any time?

Yes. Upgrade, downgrade, or cancel directly from your billing dashboard. Changes prorate for the current billing period and take effect immediately.

What payment methods do you accept?

All major credit cards via Stripe. Billing is monthly with no long-term contracts.

Is there a free trial or free tier?

Every calculator is free to use on calcmountain.com — that is the permanent free tier. The $19/mo Starter plan is the entry point for embedding calculators on your own domain.
