Received Bonus
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.

Geothermal Technician Average Hourly Wage in Tonga

7 TOP per hour

The average hourly wage (pay per hour) in Tonga is 7 TOP. This means that the average Geothermal Technician in Tonga earns approximately 7 TOP 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.
