I've never calculated the exp before even though I was curious about it as well. Knowing everything else in the game, the values are done using integer math (so decimals are truncated, not rounded) which mean you probably get more exp by waiting until the resources are near full.

As for leveling up, there is no downside to doing it fast. You will get more BP and vit which will only make it easier to rank. Just be careful not to level up with full vit or bp (although everyone does it a few times anyway)
