FAQ

Common Questions

Does the plugin work with Elementor / Divi / Beaver Builder? ▼
Yes. Any WordPress page builder that supports shortcodes will work. In Elementor, add a Shortcode widget and paste your [studycalcs] code.
Will it slow down my site? ▼
No. The calculator loads inside a lightweight iframe with loading="lazy" — it doesn't block your page, execute on page load, or add any scripts to your global scope.
Can I use multiple calculators on the same page? ▼
Yes. Drop as many [studycalcs] shortcodes as you like on one page — each renders independently. Great for building a dedicated tools page.
Do I need to update the plugin? ▼
The plugin is just a shortcode wrapper — the calculator itself is served from studycalcshub.com. Updates to the calculators are live immediately with no plugin update required on your end.
Is the attribution link required? ▼
Not enforced, but sincerely requested. The "Powered by Study Calcs Hub" link is how we keep the tool free for everyone. Set attribution="0" to hide it — but please consider leaving it on.
