It is extremely useful, as the HP 12c Platinum includes all the essential functions needed in accounting.

It is interesting to see that the HP 12c Platinum has remained on the market for the last 30 years without ever receiving a revised version. While some adjustments were made to the design, the original form and function have been preserved to this day, which is a hallmark of the HP 12c Platinum and the entire series.
