4.3 Calculation of the costs of developing software
In the economic part of the thesis calculates cost estimates for design work, and calculates the cost-effectiveness of the developed software system.
To the estimate of expenses include the following outcomes:
• cost of materials;
• cost of the basic and additional salary;
• unified social tax;
• cost of maintenance and operation of equipment;
• Other cash costs.
4.3.1 Calculation of the cost of materials
For the work, necessary to organize one work place and one workstation to install the server part of the software package. To save the server part of the software in the design stage can be set in the workplace programmer. Needed one PC with processor intel core i3 – 10000tg
Also, in the development of complex software following materials were used:
1. Pens and pencils - 300 tg.
2. Notebooks - 500 tg
3. Mouse - 3200 tg
4. USB Flash Drive 4GB - 2000 tg.
5. Headphones - 2000 tg
6. Books - 5000 tg
7. Other materials - 1000tg.
Total: 14000.00 tg.
Total expenditure on materials is: 114 000 tg.
4.3.2 Expenditure on salaries
The basic wage is calculated based developer of salary (Table 4.2.1.), As well as the duration of individual stages of work in the development of software system.

The average number of working days in a month is 22 days.
Additional monthly fee is charged at the rate (Kad) of 20% of the basic salary and is:
S = Sm * Kad = (130000*20)/100 = 26000tg.
Accrual of social security payroll is 26% of the basic salary:
P = Sm* 26% = 130000 * 26% = 33800tg.

4.3.3 The costs of operation and maintenance of equipment
Development of software system was made on a laptop. The cost of a single PC is 100 000 tenge.
The cost of 1 hour of computer time is calculated by the formula:
Ct = Se / Ty * K where
Se - Annual operating costs;
Ty - Annual Usable PC time;
K - coefficient of utilization of the PC (0.7).
The annual operating cost calculated by the formula:
Se = Sa + Sz where,
Sa - Deductions for depreciation (12.5% cost of the PC);
Sz - The cost of maintenance (2% cost of the PC).
Se = 100000 * (12.5 + 2)/100 = 14500tg.
Annual Usable time of equipment is calculated as the product of the number of working days in a year at the time of the PC in the day:
Ty = 252 * 7 = 1764 hour.
Then the cost of one hour of computer time:
Ct = Se / Ty * K = 14500 / 1764 * 0.7 = 11.7tg.
The number of working hours spent on the development and debugging of software system is (66 * 8) = 528 hours. Thus, the cost of maintenance and operation of the PC are equal to:
P = 528 * 11.7 = 6177.6 tg.
