MongoDB Certified DBA

Database administrators and application developers may wish to add a MongoDB certification to their profile. At $150 and no maintenance fee, it’s practically free and can add a couple grand each year to your salary.

  • Five-year cost: $150 exam fee
  • Five-year average potential ROI: $14,095 total
  • Exam: 90 minutes online
  • Prerequisites: None, but MongoDB recommends you understand system programming and database fundamentals, as well as basic JavaScript.
  • Difficulty: People rate the MongoDB certification as moderate
  • Training: MongoDB offers free online training and prep materials, making it even more of a steal


The Certificate of Cloud Security Knowledge (CCSK) isn't just one of the cheapest certifications, it's also the highest-paying. Aimed primarily at cloud and InfoSec pros, the CCSK is also recommended for people who manage cloud vendors and contracts. The CCSK doesn't validate or substitute for practical experience, but it's a great way to demonstrate knowledge of cloud models, security risks and best practices. Many IT pros obtain it in conjunction with a higher-level cloud certification. 

  • Five-year cost: $345 exam fee, which also includes a free retake; free update modules are offered with new versions; no continuing education or maintenance fees
  • Five-year average potential ROI: $121,550
  • Exam: 90 minutes online; open book
  • Prerequisites: None
  • Difficulty: Hard
  • Training: The essential documents are free but many people recommend formal training to increase your chance of passing the test

Top 5 highest-paying IT certifications 

If you're looking for ROI, these certifications offer the most reward for your monetary investment. Because most certifications cost more than the exam fee, we've calculated a five-year cost that includes maintenance fees, recertification costs within five years and required continuing education. The five-year return reflects the potential salary increase multiplied by five years, minus how much you pay for the certification.

It's important to note that certifications—especially advanced ones—won't necessarily help your career or earnings if you don't have practical experience to go with them. And while some companies do reward current employees for obtaining certifications, many do not. The real value of certifications is in helping you get promoted or obtaining a higher-level position.
