You may be considering enrolling in a coding bootcamp, but you have some questions first. Some common questions include:

• How much is a coding bootcamp?

• Are bootcamps worth it?

• Do coding bootcamps work?

The good news is that coding bootcamps do work. In fact, bootcamp grads see a median salary increase of$22,000 over their pre-bootcamp jobs. Considering that the average cost of a coding bootcamp is$13,579, that's a pretty good return on investment (ROI). 

What is a coding bootcamp?

What are coding bootcamps? Coding bootcamps are intensive training programs designed to quickly prepare students for careers in tech. You can find bootcamps for software engineering, data science, cybersecurity, and other tech careers. Most full-time bootcamps last around three to four months. Part-time bootcamps take longer but allow students to attend without quitting their jobs.

Coding bootcamps appeal to people who want to start a new career quickly without taking four years to earn a bachelor's degree. They also appeal to people who already have a four-year degree but want to improve their skills or gain new skills in order to advance their careers.

What are the requirements for a bootcamp?  

The requirements vary from one bootcamp to another. Some are designed for complete beginners, while others require some coding experience. Check with your bootcamp provider to find out if coding experience is required. Even beginner-friendly bootcamps typically require a good grasp of basic math and English proficiency. 

Most coding bootcamps require a high school diploma or GED. In addition, you may have to take an assessment or participate in a technology interview. These tests evaluate your coding skills and ability to think like a programmer. Many bootcamp providers offer pre-work or free introductory courses that help you prepare for the bootcamp.

What jobs can I get after a bootcamp?

You can qualify for a variety of jobs after taking a coding bootcamp. Some of the most common are junior developer, front-end or back-end web developer, full-stack web developer, software developer, and software engineer.

Junior developer: Junior developers represent the bottom rung on the software developer career ladder. They are just getting started in their careers. Junior developers may work in mobile app development, software development, or web development. They earn an average of$53,800 per year.

Front-end developer: These professionals work on the front end of a website, which is the part that users can see and interact with. They format text, insert links where needed, and control the overall look of the website. They may design forms for user input as well. They earn an average of$75,310 per year.

Back-end developer: Back-end developers work on the back end of the website. That means they work on what you don't see. For example, if the site has a login form, the programming that lets the website find your account and pull it up is happening in the back end and was likely programmed by a back-end developer. These professionals earn an average of$81,160 per year.

Full-stack web developer: Full-stack web developers work on both the front end and back end of the website. They need to know the programming languages that are used in both. Surprisingly, they don't earn more than front-end or back-end developers. Full-stack web developers earn an average of$67,170 per year. It pays to specialize.

Software developer:These professionals evaluate users' needs and create software designed to meet those needs. They create models and flowcharts that show how a program should function. Programmers then use those models and flowcharts to help them create the code to run the program according to the software developer's specifications. Software developers earn an average of$72,590 per year.

Software engineer: Software engineers work with designers to create a variety of software products. They might work on video games, operating system software, or other applications. Software engineers use engineering principles as well as programming knowledge to help them plan their projects. They earn an average of$87,550 per year.

How can I calculate a bootcamp's return on investment? 

Are dev bootcamps worth it? One way to find out is to calculate the return on investment you can expect to receive if you attend one. ROI is a calculation that helps you determine whether the amount you will make from an investment is enough to be worth making the investment.

You can calculate ROI by dividing the net return on the investment (the amount of profit) by the cost of the investment and multiplying by 100. So, to figure the one-year ROI of a bootcamp, you would take the amount you expect to make in your new job and subtract the amount you make now. You would then divide that number by the cost of the bootcamp plus the cost of not working for the duration of the bootcamp. Multiply that by 100 to get the ROI.

Let's do an example. You currently earn$35,000 per year as an administrative assistant and expect to earn$60,000 per year after your bootcamp. The bootcamp costs$15,000 and you will miss three months of work, which will cost you$8,750.

          ($60,000-$35,000)

ROI = --------------------------  x 100 = 105.26%

          ($15,000+$8750)

Where else can you get a return of over 100% on your investment? This calculation assumes that you'll see all of your return in the first year, but you'll keep earning returns on an investment in your education for the rest of your life.

In most cases, coding bootcamps will provide a good return on your investment. However, that is not always the case. For example, if you currently make$60,000 per year and you expect to make the same after the bootcamp, you are not going to see any return on your investment. Make sure to do the math yourself with your own numbers to determine whether the bootcamp is worth it.

How to market a bootcamp on a resume 

Since coding bootcamps are relatively new, you might need to put a little extra effort into proving to a hiring manager that you have the right qualifications for the job. Here are a few tips that might help.

1. Link to your online portfolio in the header of your resume. This is a good way to show the hiring manager what you can do.

2. List your most impressive software projects under the job you created them for or in a separate section titled "Projects." Be sure to list the programming language you used for each one. This will help you get past any automated screening software.

3. List your bootcamp along with any college experience in the education section. If you have a college degree, be sure to include it
