How many attacks does that next upgrade actually cost you? This calculator turns an upgrade price into concrete numbers: how many attacks you need, how many hours of farming that is, and how many overnight sessions it would take. Enter your own average loot per attack, yours is the only number that matters, and the results update as you type.
Rough example only: many farmers see something like 150k to 400k total loot per attack depending on league and dead-base luck. Use your own average.
Default 8. Search time, battle length, and troop training all vary, adjust to your pace.
No magic: attacks needed is the upgrade cost divided by your average loot per attack, rounded up. Hours is attacks divided by attacks per hour. Nights assumes an 8 hour overnight farming session. The output is only as honest as your input, so track a few real sessions and use your true average rather than a hopeful one. Loot per attack swings a lot with league and dead-base availability, which is exactly why we do not preload a number for you. If you want to raise that average, our farming guide covers armies, league choice, and dead base hunting.
Run a late-game upgrade through the calculator and the result is rarely comforting. Big Town Hall upgrades routinely work out to dozens of attacks, spread over many hours, and that is for a single upgrade out of the dozens on your to-do list. Multiply by every building, every level, and every hero, and you can see why so many players stall out in the late game. The loot is gettable, the hours are the problem.
If the calculator just told you your next upgrade is 50 attacks away, you have two options: grind them out by hand, or let Goblins Farm run them. It plays Clash of Clans inside the free BlueStacks emulator on Windows or macOS, skips bases below your loot thresholds, attacks the ones worth taking, and stops on its own when your gold, elixir, or dark elixir target is reached.
