It depends on how much you can invest in it – The money and your time.
To answer this question, we also need to know about your goal. You can continue with other Cisco certifications or maybe, you can change the line and mix it with something else.
Let’s have a look, which job openings are on the job boards to take advantage of a CCNA certificate.
I- You have only a CCNA certificate and you are on the way to be a network professional
This means that you are beginning your journey to becoming a network expert. You can work as a junior admin in an environment where experienced network professionals work. You will do some daily tasks including monitoring, hardware installations (as the second staff member), and routine things like configuration backup. You cannot earn too much money in this position; however, it is a good investment for your bright future. If you spend one or two years at this step while preparing for your CCNP, you will be rewarded for your efforts with a good income boost and job security. CCNA certificate is a mandatory and foundational step for CCNP.
II- You have only a CCNA cert and you do not want to invest more in it
If you say, “CCNA is enough for me and I don’t want to waste more of my time and money for certifications”, then you can find a job in a mid-size company as system/network admin. You have to look after windows servers and maybe some other systems. You can make an acceptable amount of cash and work in an environment without too much hierarchy. If you are good at relationships and you are a practical kind of person, this is the exact job for you. The CCNA certificate is sufficient for this position. It will be very helpful in your career.
III- You have CCNA + some Microsoft certifications (like MCSE) + experience
In this case, your dominant skills are system administration skills. You already proved yourself in this area and can work in a Multinational Enterprise branch as a senior system admin. You can handle network administration tasks with your CCNA certificate or better, in very large structures, it will let you lead a team composed of both system administrators and network administrators.
IV- You have CCNA + Security certification (CISA+GIAC) + 3-4 years’ experience
You can work as a System Security Engineer in an Enterprise environment or you can work in a consulting company as an information security auditor. Your CCNA certificate will let you have more expertise on network related issues and support your success.
V-You have CCNA + more than ten years’ experience on Windows & UNIX
If you have development skills, project management skills and you have spent a considerable amount of years in several areas of IT business, then a CCNA is not a big part of your skillset, but at least it shows that you are still in touch with the practicalities of network operations and it helps you to achieve the Enterprise Architect position.
As a step or as a component, CCNA is a valuable item in your personal inventory. It is worthy to get it and anybody can get the certificate, but you need other skills and experience to utilize it to the maximum extent. Initially, you cannot expect high paying jobs, but with some experience, you can climb the ladder of success. For students, I strongly recommend participating in Cisco programs in colleges. This will help them make an easy start for their careers.
If you would ask, “How much money can you make with a CCNA certificate?” my first answer would be “No, CCNA itself does not make money for you.”
