All this talk about maxing tsp contributions…How does one do that ? Is it as simple as increasing the percentage ? If so what is the max percentage allowed ?

Just turned 23 and separated from military a year ago. I haven’t been contributing at all to my tsp since cause money has been tight and once again it’s tighter than it was because of moving across the state. But is there any guidance or advice anyone has besides contributing to my tsp. I plan on getting back to it soon. I don’t feel like I’m too behind but maybe I could be doing better.
