Is a Master's degree or an MBA worth it? Should you pursue higher education?

A Master's degree program or any post-graduate program in Bulgaria costs anywhere from 16,500 Bulgarian Lev(s) to 49,500 Bulgarian Lev(s) and lasts approximately two years. That is quite an investment.

You can't really expect any salary increases during the study period, assuming you already have a job. In most cases, a salary review is conducted once education is completed and the degree has been attained.

Many people pursue higher education as a tactic to switch into a higher paying job. The numbers seem to support the thoery. The average increase in compensation while changing jobs is approximately 10% more than the customary salary increment.

If you can afford the costs of higher education, the return on investment is definitely worth it. You should be able to recover the costs in roughly a year or so.

The figures provided here are averages of numbers. Those figures should be taken as general guidelines.

Bulgaria / All Professions

The term 'Annual Salary Increase' usually refers to the increase in 12 calendar month period, but because it is rarely that people get their salaries reviewed exactly on the one year mark, it is more meaningful to know the frequency and the rate at the time of the increase.

How to calculate the salary increment percentage?

The annual salary Increase in a calendar year (12 months) can be easily calculated as follows: Annual Salary Increase = Increase Rate x 12 ÷ Increase Frequency

The average salary increase in one year (12 months) in Bulgaria is 4%.

A Drilling Engineer is considered to be a low bonus-based job due to the generally limited involvement in direct revenue generation, with exceptions of course. The people who get the highest bonuses are usually somehow involved in the revenue generation cycle.

69% of surveyed staff reported that they haven't received any bonuses or incentives in the previous year while 31% said that they received at least one form of monetary bonus.

Those who got bonuses reported rates ranging from 0% to 4% of their annual salary.

No Bonus

Types of Bonuses Considered

Individual Performance-Based Bonuses

The most standard form of bonus where the employee is awarded based on their exceptional performance.

Company Performance Bonuses

Occasionally, some companies like to celebrate excess earnings and profits with their staff collectively in the form of bonuses that are granted to everyone. The amount of the bonus will probably be different from person to person depending on their role within the organization.

Goal-Based Bonuses

Granted upon achieving an important goal or milestone.

Holiday / End of Year Bonuses

These types of bonuses are given without a reason and usually resemble an appreciation token.

Bonuses Are Not Commissions!

People tend to confuse bonuses with commissions. A commission is a prefixed rate at which someone gets paid for items sold or deals completed while a bonus is in most cases arbitrary and unplanned.

What makes a position worthy of good bonuses and a high salary?

The main two types of jobs

Revenue GeneratorsSupporting Cast

Employees that are directly involved in generating revenue or profit for the organization. Their field of expertise usually matches the type of business.

Employees that support and facilitate the work of revenue generators. Their expertise is usually different from that of the core business operations.

A graphics designer working for a graphics designing company.

A graphic designer in the marketing department of a hospital.

Revenue generators usually get more and higher bonuses, higher salaries, and more frequent salary increments. The reason is quite simple: it is easier to quantify your value to the company in monetary terms when you participate in revenue generation.

Try to work for companies where your skills can generate revenue. We can't all generate revenue and that's perfectly fine.

Bonus Comparison by Seniority Level

Top management personnel and senior employees naturally exhibit higher bonus rates and frequencies than juniors. This is very predictable due to the inherent responsibilities of being higher in the hierarchy. People in top positions can easily get double or triple bonus rates than employees down the pyramid.

Drilling Engineer Average Hourly Wage in Bulgaria

16 BGN per hour

The average hourly wage (pay per hour) in Bulgaria is 16 BGN. This means that the average Drilling Engineer in Bulgaria earns approximately 16 BGN for every worked hour.

Hourly Wage = Annual Salary ÷ ( 52 x 5 x 8 )

The hourly wage is the salary paid in one worked hour. Usually jobs are classified into two categories: salaried jobs and hourly jobs. Salaried jobs pay a fix amount regardless of the hours worked. Hourly jobs pay per worked hour. To convert salary into hourly wage the above formula is used (assuming 5 working days in a week and 8 working hours per day which is the standard for most jobs). The hourly wage calculation may differ slightly depending on the worked hours per week and the annual vacation allowance. The figures mentioned above are good approximations and are considered to be the standard. One major difference between salaried employees and hourly paid employees is overtime eligibility. Salaried employees are usually exempt from overtime as opposed to hourly paid staff.
