The step most players are planning right now. The summary shows the Gold and time for the Town Hall itself, the weapon levels and what Town Hall 18 unlocks.
| Level | Cost | Time |
|---|---|---|
| Level 1 | Comes with Town Hall 18 | |
| Level 2 | 18,000,000 Elixir | 7d |
| Level 3 | 22,000,000 Elixir | 9d |
| Level 4 | 26,000,000 Elixir | 11d |
| Level 5 | 28,000,000 Elixir | 13d |
Upgrading too early is the most common way to fall behind. In Clan War, matchmaking weighs your whole village, so a rushed base meets stronger opponents. In multiplayer battles your new Town Hall level counts too, while your own heroes and defenses are still capped at the old level.
On my TH18 account, MoonLight ID #9280QPL8G, I still have a few defenses to upgrade, mainly traps, bombs and Seeking Mines. My main armies are maxed, but the rest of my troops are a long way behind. I plan to max a few of them before and during the Hammer Jam event.
What I have learned on MoonLight, TH18: don't rush to Town Hall 19 if you are far behind. Plan first, then act. If you are between TH11 and TH13, move up to TH14, where Pet upgrades don't use a builder. If you are between TH14 and TH18, master your attacks before you move up.
Gold Pass and Hammer Jam cut both Gold and time. Builder Potions only cut time, by 9 hours each. Boosts multiply: 20% off, then half off, leaves 40% of the base.
| Boosts | Share of base cost | Share of base time |
|---|---|---|
| None | 100% | 100% |
| Gold Pass 10% | 90% | 90% |
| Gold Pass 20% | 80% | 80% |
| Hammer Jam | 50% | 50% |
| Gold Pass 20% + Hammer Jam | 40% | 40% |

On MoonLight, TH18, I save Builder Potions for when every builder is busy and none is close to finishing, and I use them only once I have the resources to start the next upgrades.

Gold. Every Town Hall level is paid in Gold, and the full cost is taken when the upgrade starts.
Going from TH17 to TH18 costs 25,000,000 Gold. With a 20% Gold Pass it drops to 20,000,000 Gold.
12 days of builder time. With a 20% Gold Pass it takes about 9 days 14 hours.
Yes. The calculator applies the Gold Pass builder discount of 10% or 20% to both cost and time. See how boosts change the cost for every combination.
Yes, but you only get half of the Gold back. Plan the timing before you tap upgrade.
Supercell has not announced a date. Based on TH17 and TH18, the 3rd to 4th week of November 2026 is the most likely window. See our TH19 release date guide.
