Planning a hero upgrade meant opening a wiki, adding up costs level by level, then working out how much a Gold Pass or a few Builder Potions would save. I wanted one place that does the maths for you.
COCUpgrade does exactly that: pick a hero, your current and target level and your boosts, and you get the total cost and time straight away.
Calculators for defenses and walls are next.
I review the data after every game update, checking upgrade costs and times against the Clash of Clans Fandom wiki and my own accounts. If a number on the site does not match the game, email cocupgradewiki@gmail.com with the hero, the levels and what the game shows, and I will fix it.
