If you're regularly at 85%, get 32GB.

Yes, that’s a clear sign. 85% usage means your system is close to swapping memory to disk, which kills performance if it runs out.

The real question: what are you doing when it hits 85%? If it’s just a few Chrome tabs and Word, something’s wrong—maybe a memory leak or too many background processes. But if you’re running VMs, large development builds, heavy photo/video editing, or gaming with a bunch of mods or fast multitasking, then 32GB is the right move.

Here’s the practical test: when you’re at 85%, does everything feel sluggish? Does switching apps take a second? Do you see the “low memory” warning? If yes, you’re bottlenecking. If everything is still snappy, you might be fine—Windows reserves a chunk even when idle. But if you’re consistently pushing close to 16GB on normal workdays, upgrade.

Don’t wait until you’re at 100% and crashing. RAM is cheap relative to the headache of running out.

Future you will thank you when you don’t have to close half your apps just to open a PDF.
