RAM use should always be 100% for reasonable definitions of "use". There's always more disk pages to be cached unless the machine has just booted. If they're not all being used, it means something temporarily flushed all the pages which is actually a bad thing.

I think it’s reasonable to assume that OP was talking about user space applications, not kernel disk cache.

Adding up the memory use of apps isn’t actually a good way to calculate RAM needs though. It undercounts (because file caching matters too) and overcounts (because many things are fine swapped out).
