I'll just give some figures, using base values taken from UESP:
Mage - 4 (non-reusable) consumables per 8 damage and 60 seconds of 40 armor, short-mid range (flames, oakflesh, potion of minor magicka)
Archer - 1 (potentially reusable) consumable per 14 damage, unlimited 46 armor, long range (long bow, iron arrow, imperial light armor set)
Melee - unlimited 7 damage, unlimited 63 armor, short range (iron sword, imperial armor)
Mage - 11 (non-reusable) consumables per 75 damage and 30 seconds of 80% damage removal (lightning storm, dragonhide, potion of plentiful magic)
Archer - 1 (potentially reusable) consumable per 43 damage, unlimited 82 armor (daedric bow, daedric arrow, dragonscale armor)
Melee - unlimited 14 damage, unlimited 108 armor (daedric sword, daedric armor)
Start game (as shown in the first set of figures), the mages are getting the least bang for the buck. Especially as that armor spell is pretty much a necessity with the range limit that seems to exist on the continuous damage spells like flames. Archery possibly has the best of it, given their effective range, while melee is in the middle, due to being limited to close range only.
End game (second set of figures), archers are easily at the forefront, given the damage, armor, and range. Again I'd say melee is in the middle, due to the ability to indefinitely deal damage. Mages may get the best damage, and the 80% damage removal, but to have enough magicka to cast each spell only once, they'd need to be level 75.
These figures assume no levels, no perks, and no enchantments/alchemy/smithing, using only base damage and base magicka cost. Also the attempt was an equal comparison between magic and melee, so the figures use one handed sword, and single hand casting.
Edit: As an interesting side note, using flames for 10 seconds gives 5 damage more than 1 second of lightning storm, for only 2 more magicka. So from a damage:cost point of view, the novice spell gotten right at the start is actually better than the end game master spell.
