Frequently Asked Questions

What is a credit?

In Dlubal CALC, a credit is the smallest billing unit. Each action, such as a chat, an RFEM call, or a PDF report, consumes a fixed number of credits, as shown in the table above.

What will happen if I run out of credits?

You will see a notice in the chat and your monthly credits will refill automatically at the start of the next billing period. With any paid plan, you can purchase a credit top-up pack at any time. With the Free plan, upgrading is the way to get more credits.

Can I buy extra credits without changing my plan?

Yes, with any paid plan, you can purchase one-time credit packs ranging from quick top-ups to large packs with volume discounts. Purchased credits never expire and are only used once your monthly credits have been used up.

Is it possible to cancel at any time, and what is the process for yearly billing?

Yes, you can cancel at any time. Your plan will stay active until the end of your paid period, and then it will revert to the free plan. With yearly billing, you get two months free (about 17% off), since it costs 10 times the monthly price.

More information about pricing details

Will my credits expire at the end of the month?

Credits from the monthly plan reset at the end of each billing period and do not roll over. However, credits from purchased top-up packs never expire and remain in your account permanently.

How do team credits differ between the Professional and Enterprise plans?

The Professional plan includes team management for up to five members, each of whom uses their own monthly credits. With the Enterprise plan, the entire team shares a single credit pool, and pricing is based on the entire team rather than on individual users.
