∫Key Calculus

Pricing and Billing

  • Subscriptions are $75/month, billed annually. Key Calculus partners with Stripe for payment processing.
  • Subscriptions will renew automatically on the anniversary of the original subscription purchase unless you cancel prior to the anniversary date. Subscription renewals will be billed at the current price as of the renewal date.
  • Subscriptions can be cancelled at any time, but cancelled subscriptions will remain accessible until the renewal date. So, for example, if you purchase a subscription on March 15, 2024, and cancel it on April 5, 2024, you will still have full access to the Key Calculus application until March 15, 2025.

    There are no refunds for cancelled subscriptions, so please take advantage of the free 30 day trial to determine if Key Calculus is right for you before purchasing. We recommend that you try Key Calculus using the same device and browser you intend to use for production work with the application.
