It's usually always worth it to upgrade mods if you intend to put them in a weapon at all in the first place. 10% damage for 6 cost up front is extremely expensive, but you get an additional 10% damage for only 1 additional cost on each upgrade.

Basically, at rank 1, you're only getting 1.66% damage per cost, but at rank 5, you're getting 5.45% damage per cost ~ almost 5x the efficiency.
