Time for the full version
The free version is meant for private use and caps results at 1,000,000 after 31 days. A one-time licence removes both limits — and lets you use DeskCalc at work.
Use it at work
The free version is licensed for private use only. Any commercial use — office, practice, freelance — requires a licence.
No calculation limit
After 31 days the free version caps results at 1,000,000 — enough for private use, not for business figures. The full version has no ceiling.
Lifetime, no subscription
Pay once, keep it. Free updates within V11.x, and it runs on terminal servers with the multi-user licence.

More than 10 seats? Running a terminal server?
Accounting firms rarely install a calculator on just one machine. Tell us how many seats you need and how you deploy — you get a written quote, not a sales call.
- Terminal server, Citrix and RDS — licensed per seat, not per machine.
- One licence file, one invoice — no key juggling for your IT.
