You are right, you will lose 30% ( assuming you don't have another charm of a lower level to put in the other slot ).

It means there are trade offs on when to merge charms vs. bag space management. Defer merging, get more benefit short term, but risk slowing down the upgrading of charms as that is one more long term space taken from the combined available slots and total bag space. Or merge now, take a short term space hit ( but not as long as the not merge case ), get less benefit from the combined charms ( assuming you don't have a lower level one ), but get that much closer to having max level charms.
