IT certifications can improve your job prospects and earning power, but the payoff depends on which certification you choose, what your current role is, and how much time and money you're willing to spend

An IT certification proves to employers that you know specific technologies or practices — it's a credential you earn by passing an exam, not a degree. Some certifications open doors to jobs you couldn't get without them. Others add a line to your resume that hiring managers notice. Some cost hundreds of dollars and months of study for a modest bump in pay. The difference matters, and it's worth understanding before you commit.

The real question isn't whether certifications are worth it in general. It's whether a specific certification is worth it for you, right now, in the role you want next.

Key Takeaways

  • Entry-level certifications like CompTIA A+ and Security+ can be prerequisites for certain government and corporate jobs, making them necessary rather than optional for those paths.
  • Cloud certifications from AWS, Google, and Microsoft often lead to higher salaries and more job openings than general IT certifications, but require hands-on experience to pass.
  • The cost of a certification — exam fees, study materials, and your time — ranges from $200 to $500 for entry-level to $1,000+ for advanced cloud credentials.
  • Certifications expire or require renewal every two to three years, so factor in ongoing costs if you plan to keep the credential current.
  • Your current job title and experience matter more than the certification itself; a certification helps you move to a specific next role, not just any better job.

When a certification is actually required

Some employers and government agencies won't hire you without specific certifications. If you're applying for a federal IT job, a Department of Defense contract role, or a position at a bank or healthcare company with strict compliance rules, you may need CompTIA Security+ or a similar baseline credential before you can even interview. These aren't optional — they're gatekeeping requirements.

Check the job postings for roles you actually want. If three out of five postings say "Security+ required" or "AWS Solutions Architect certification preferred," that's a signal. If none of them mention certifications, you're probably not blocked by the lack of one. This is the fastest way to know whether a certification is worth your time: does the job you want require it or strongly prefer it?

Government and defense contracting is the clearest case. Private companies vary widely. A startup may not care about certifications at all. A Fortune 500 company may require them for promotion or for certain roles. Ask people already in the role you want — they'll tell you whether the certification mattered for them.

How much certifications actually change your salary

Salary bumps from certifications are real but uneven. Someone with a cloud certification (AWS, Google Cloud, Azure) often sees a $5,000 to $15,000 annual increase over someone in the same role without it, according to job postings and salary surveys. Entry-level certifications like CompTIA A+ show smaller increases — sometimes $2,000 to $5,000 — because they're more common and often paired with less experience.

The catch: the salary increase usually comes when you move to a new job, not when you add the certification to your current one. You study for three months, pass the exam, and then you're a more competitive candidate for the next role. Your current employer may not raise your pay just because you earned a credential. Plan to job-hunt after you certify if you want to see the salary benefit.

Certifications also matter less if you already have years of experience in the field. Someone with eight years of hands-on cloud work may not see much salary movement from an AWS certification because employers already know what they can do. Someone with two years of IT support work might see a bigger jump from CompTIA Security+ because the certification signals readiness for a security-focused role they couldn't otherwise access.

The real cost: time, money, and renewal

The exam fee is only part of the cost. CompTIA A+ costs about $240 per exam (you take two), plus study materials that run $100 to $300. AWS Solutions Architect Associate costs $150 for the exam, but most people spend $200 to $500 on courses and practice tests. Advanced certifications like AWS Solutions Architect Professional or Kubernetes certifications can run $300+ for the exam alone, plus $500+ in study materials.

Then there's your time. Expect 40 to 100 hours of study for entry-level certifications, 80 to 200 hours for intermediate ones, and 150+ hours for advanced credentials. If you're working full-time, that's three to six months of evenings and weekends. Some people can do it faster; some need longer. Factor in the real cost of your time — if you're earning $25 an hour, 100 hours of study is $2,500 in opportunity cost, even if you're not literally losing that money.

Most certifications expire after two or three years. You'll need to renew by passing another exam or earning continuing education credits. That's another $150 to $300 every few years, plus study time. If you earn a certification and then leave the field, you've paid for something you won't use.

Cloud certifications versus general IT certifications

Cloud certifications (AWS, Google Cloud, Microsoft Azure) tend to have better job market outcomes than general IT certifications. There are more open positions, the salary bump is larger, and employers actively seek people with these credentials. If you're choosing between CompTIA Network+ and AWS Solutions Architect Associate, the AWS cert usually leads to more opportunities and higher pay — but it also requires hands-on experience with AWS to pass.

General IT certifications like CompTIA A+, Network+, and Security+ are broader. They teach foundational concepts that apply across many jobs and employers. They're easier to pass without real-world experience because the exams test knowledge more than hands-on skill. They're also more universally recognized — a Security+ is respected everywhere, while an AWS cert is specific to Amazon's platform.

The trade-off: cloud certifications are more lucrative and in-demand right now, but they're narrower. If you get an AWS cert and then your next job uses Google Cloud, you'll need to recertify. General IT certs are more portable across employers, but they don't lead to as many high-paying roles. Choose based on the actual jobs you're targeting, not on which certification sounds more impressive.

What certifications won't do for you

A certification alone won't get you hired if you have no relevant experience. Employers want to see that you can actually do the work. A certification shows you studied the material and passed an exam; it doesn't prove you've built anything, solved real problems, or worked on a team. If you're switching careers entirely — from retail to IT — a certification helps, but you'll also need a portfolio, a bootcamp, or an entry-level job to prove you can perform.

Certifications also won't make up for poor communication, missing soft skills, or a bad interview. You can have every credential on paper and still lose the job to someone with fewer certifications but better people skills or a clearer explanation of what they've built.

And certifications won't protect you from industry changes. If you certify in a technology that becomes obsolete in five years, the credential becomes a line on an old resume. Choose certifications in technologies that are actively growing and that you'll actually use in your next role.

How to decide if a specific certification is worth your time

Start by looking at real job postings for the role you want next. Search LinkedIn, Indeed, and your local job boards for that title. Count how many postings mention the certification you're considering. If it appears in 60% or more of the postings, it's probably worth doing. If it appears in 10% or fewer, it's probably not a priority.

Then talk to people already in that role. Ask them whether the certification was required, helpful, or irrelevant. Ask whether they saw a salary bump after earning it. Ask how long they studied and whether they'd do it again. This conversation is worth more than any article because they know the actual job market in your area and industry.

Finally, calculate your own cost-benefit. If the certification costs $500 total and takes 80 hours of study, and it leads to a $10,000 annual salary increase, that's a good return. If it costs $1,000 and takes 200 hours and leads to a $2,000 increase, it's less clear. If you're not sure you'll stay in IT, the calculation changes again — you might not recoup the cost before you leave.

Frequently Asked Questions

Do I need a certification to get an IT job?

Not always. Many IT jobs don't require certifications, especially if you have a degree in computer science or related field, or if you have years of hands-on experience. However, some roles — particularly in government, defense, healthcare, and finance — do require specific certifications like Security+ before you can be hired. Check the job postings for roles you actually want to see whether certifications are listed as required or preferred.

Which certification should I get first?

That depends on your current role and where you want to go next. If you're in general IT support and want to move into security, Security+ is a common next step. If you're in infrastructure and want to move to cloud, start with a cloud provider's foundational cert (AWS Cloud Practitioner, Google Cloud Associate, or Azure Fundamentals). If you're not sure, CompTIA A+ is the broadest entry-level option, but it's also the least specialized and may not lead to the highest-paying roles.

How long does it take to study for a certification?

Entry-level certifications like CompTIA A+ typically require 40 to 100 hours of study. Intermediate certs like Security+ or AWS Solutions Architect Associate usually take 80 to 200 hours. Advanced certifications can require 150+ hours. The actual time depends on your background, how much hands-on experience you already have, and how fast you learn. Most people study part-time over two to six months.

What happens if I fail the exam?

You can retake it. Most certification programs let you retake the exam after a waiting period (usually 14 days). You'll pay the exam fee again, so budget for the possibility of needing two or three attempts. Many people pass on the first try if they study thoroughly, but it's not may provide. Some study programs include practice exams that closely match the real test, which can improve your odds.

Do certifications expire?

Most do. CompTIA certifications are valid for three years. AWS certifications are valid for three years. Microsoft certifications vary but are typically valid for one to three years. After expiration, you can renew by passing another exam or, in some cases, by earning continuing education credits. If you let a certification expire and don't renew it, you can't list it as current on your resume, though you can mention that you previously held it.
