The expected economic effect is the main indicator of the return on the implementation of the production automation system. It is calculated using the formula:
E = E(p) – E(n) * K(p)
Where:
E(r) – annual savings;
E(n) – standard coefficient;
K(p) – capital investments in the creation of the project and implementation of the system.
K(p) is calculated based employment database on the duration of work at a specific stage. It is important to know that design is understood as the activity of preparing the entire system or any part of it, and implementation is the commissioning of the APP structure.
Calculation of automation costs
At the beginning of the calculations, the duration of each stage of work is determined, from writing the technical task to compiling reports. The value of this indicator is taken either from the standard tables or calculated using the formula:
T(o) = (3 * T(min) + 2 * T(max)) / 5
Where:
T(o) – expected period (stage) of activity;
T(min) and T(max) – minimum and maximum duration of work.
Estimated capital costs are calculated using the formula:
K(k) = C + Z(n) + M(n) + N ,
Where:
C – price of the APP program;
Z(п) – the amount paid to specialists;
M(p) – expenses for using computers;
H – overhead costs at the design and implementation stage.
The cost of operating accessories is calculated by adding up all the costs of purchasing them, using wholesale prices as the basis.
Operating costs are the funds spent on maintaining the programmers who service the system, as well as the costs of ensuring the operation of the program itself and the maintenance of buildings and structures.
Example. A domestic organization with one accountant on staff offers its services to people. The business owners purchased a license to use the product "1C: Enterprise Accounting 2.0" and hired employees of the company "1C" to implement it. Let's assume that the cost of the software is 11,000 rubles, and the programmer's services are 10,000. Thus, capital investments for implementation will be:
K = 11,000 + 10,000 = 21,000 rubles
The employee's monthly salary is 50,000 rubles. The total costs of maintaining personnel will be:
Z = 1 * 50,000 * (1 + 34% / 100) = 67,000 rubles.
Let's assume that the value of annual savings from implementing the program will be the same as the expected savings from increasing the productivity of the accountant, which we will calculate using the formula:
P = 67,000 * 9 = 603,000 rubles.
Economic efficiency in this case will be:
E = 603,000 – 21,000 * 0.15 = 599,850 rubles.
As a result, even with an approximate calculation of economic efficiency, the implementation of an automation system for one accountant's workstation will bring the enterprise an annual saving of 599,850 rubles. In order to achieve this figure, it will be necessary to initially invest only 21,000 rubles.
