In the publication are presented studies to determine the accuracy of the group approach in calculating the cost of technological engineering products. For this purpose, the cost price of a specific item is calculated by applying the developed approach and the group is compared with the actual cost. The results obtained show that the use of group approach enables a comparatively fast and sufficiently precise calculation of the technological cost of machine products.
