Frequently Asked Questions
Can I use Calcimator for free?
Yes. Every calculator on Calcimator is free to use, with no sign-up required. The free tier includes all calculators, real-time results, charts, and shareable links. Paid plans add convenience features like ad-free usage, export, and higher API limits.
Can I switch plans at any time?
Yes. You can upgrade or downgrade your plan at any time. When upgrading, you get immediate access to new features. When downgrading, your current plan stays active until the end of the billing period.
What payment methods do you accept?
We accept all major credit and debit cards (Visa, Mastercard, American Express, Discover) through Stripe. All payments are processed securely.
Is there a free trial for paid plans?
We don't offer a traditional free trial because the Free tier already gives you full access to every calculator. Paid plans add quality-of-life features — try the free tier first and upgrade when you're ready.
What is the API and who is it for?
The Calcimator API lets developers run calculations programmatically. It's useful for integrating calculator functionality into your own apps, dashboards, or workflows. Free users get 100 requests per day, which is enough for testing and light usage.
