Morphology
The meaning 'to accumulate' is directly derivable from combining 'stack' (to pile items) with 'up' (indicating upward increase or completion): piling things up naturally leads to a larger amount over time. This compositional motion/increase pattern is common cross-linguistically and follows a standard English verb+particle meaning, so a B1 learner who knows both constituents would likely infer the MWE's sense.
Etymology
Stack up comes from the simple image of putting things one on top of another: you make a stack and lift things up into a neat pile, so it's used to mean 'to arrange things in a neat pile'.
