Markus has already captured the key points about how the PMP® certification can positively influence your career and salary potential. His insights on the salary survey data and industry preferences are spot on.
One thing I’d like to add: if you’re aiming for a junior project manager or project coordinator role, you may be able to land it without any certification. However, if you’re targeting a senior PM position—especially in larger organizations or highly regulated industries—the PMP is almost always considered a must-have. Many recruiters and hiring managers will look for it right away when reviewing candidates for higher-level roles.
Additionally, the more senior you get, the more you will feel the "pressure" (often self-imposed) to get your PMP. After all, everyone around you has it, so you probably should, too. At least, that's how I felt back then. But... just as Harry said: It was worth it and I'd do it again.
Best of luck in your project management journey!
