Manager
Salary per day = 300,000÷21 = 14,286 RUB
Salary per week = 14,286×5 = 71,429 RUB
Cost of mentoring time =
(71,429×80%)+(71,429×50%)+(71,429×20%)+(71,429×10%) =
57,143 + 35,714 + 14,286 + 7,143 = 114,286 RUB
New employee
Salary per day = 40,000÷21 = 1,905 RUB
Salary per week = 1,905×5 = 9,524 RUB
Cost of learning time =
(9,524×90%)+(9,524×70%)+(9,524×50%)+(9,524×30%) =
8,572+6,667+4,762+2,857 = 22,858 RUB
the cost of mentoring + the cost of learning =
= 114,286 + 22,858 = 137,144 RUB
Manager
Cost of mentoring time =
(71,429×5%)+(71,429×10%)+(71,429×10%)+(71,429×10%) =
3,571+7,143+7,143+7,143 = 25,000 RUB
New employee
Cost of learning time =
(9,524×80%)+(9,524×50%)+(9,524×20%)+(9,524×5%) =
7,619 + 4,762 + 1,905 + 476 = 14,762 RUB
the cost of mentoring + the cost of learning =
= 25,000 + 14,762 = 39,762 RUB
1st week - by 75%,
2nd week - by 60%,
3rd week - by 10%.
4th week - remains the same, but compensated by others.
1st week - by 10%,
2nd week - by 20%,
3rd week - by 30%,
4th week - 25%.
Without a training program — 137,144 RUB
With a training program — 39,762 RUB
Let's calculate the benefit: 137,144 - 39,762 = 97,382 RUB.
Benefit÷salary RUB = 97,382÷40,000 = 2,4 months
Salary and training time are specific data that should not be underestimated. Having considered the dynamics of changes in the time spent on training with and without the program, you can understand in numbers whether one or another method of training a new employee is effective or not without waiting for the results of the employee's performance.
Feel free to try these formulas on your case!
In the next Part 2, we will take a deeper look at this case and try to take into account the cost of preparing a training program as an integral and, no doubt, expensive part of the process.
