S* KP (4.3)
where Q – the conditional number of operators;
KP – the coefficient depending on qualification of the developer;
B – the coefficient of increase in the expenses, connected to incompleteness of the description and need of specification and finishing, is accepted by B=1,3;
S – coefficient which is defined by complexity of the task, in this case S =85.

Summary labor input of creation of the program:
Т = tu + tр + tп + tотл + tрук + tдок; (4.6)

4.3 Calculation of a salary of the programmer
Official salary of the programmer depending on his qualification:
Ds = 65000 tenge
Annual amount of a salary:
Sy = Ds * 12; (4.7)
where 12 – number of months in a year.
Sy = 65000 * 12 = 780000 tenge ;
Award for work good results:
Sy *%P
P
=
;
100 (4.8)
where award percent %P = 7.
780000 *7
P = = 54600 tenge

Main salary:
MS = Sгод + P ; (4.9)
MS = 780000 + 54600 =834600 tenge ;
Percent of an additional salary:

Дк – Дв – Дп - До (4.10)
where До = 42 – holidays;
Дк = 365 – calendar days;
Дв = 104 – weekends;
Дп = 12 – holidays.

OffS = 834600 + 169340,34 = 1003940,34 tenge;
General salary fund from ESN
OffSesn = OffSр-н * 0,11 ; (4.13)
where 0,11 – ставка СН (социальный налог), установлен в размере 11% с 01.01.2009 года.
OffSesn = 1003940,34* 0,11 = 110433,4374 tenge ;
Annual fund of working hours:
Fгод = (Dk – Dv – Dp – Do) * tсм ; (4.14)
Fy = (365-104-12-42) * 8 = 1656 hour ;
