Your RAM usage tells you everything.

Yes, and it’s simple. Open Task Manager (Windows) or Activity Monitor (Mac) and watch your memory usage while you do your actual work. If you’re consistently above 80-90% usage and the system starts swapping to disk (high page file usage on Windows, memory pressure in the red on Mac), 32GB will help. If you’re sitting at 60-70%, you won’t see much difference.

The tricky part: some workflows (like video editing, big data processing, or running VMs) benefit from extra headroom even if you’re not pegged at 100%. But for most people—coding, browsing, office work, light creative work—16GB is still fine. If you never see it go above 80%, buying more RAM is just spending money.

Also, check your swap/compression usage. If your system is writing heavily to disk (high page file activity), that’s the real scream for more memory.

Don’t guess. Just watch for five minutes during your hardest task.
