Army buildings upgrade costs and times

Data current as of Jul 10, 2026Updated Oct 4, 2026

Army buildings are the cheapest way to make every future attack better, which is why the guides on this site keep putting them at the front of the queue. The Laboratory sets the ceiling on every troop and spell you research. The Clan Castle sets how many reinforcement troops you receive. Army Camps set how much army you bring at all. None of them defends anything, and all of them pay off on every raid and war attack from the moment they finish.

Everything in this category is paid in elixir, so it competes with your Laboratory research for the same storage rather than with defenses. The tables below list every level with its cost, upgrade time and Town Hall requirement, plus the TH Cap at each Town Hall. Barracks, the Dark Barracks and the two Spell Factories unlock new units rather than strengthening existing ones, so their levels matter only when the next unlock is something you will use. The Workshop, Pet House and Blacksmith arrive later and each opens a whole system of its own: siege machines, pets and hero equipment.

The Laboratory's research itself is on the troop, spell and siege pages; this page is about the buildings.

What to upgrade first

Laboratory first, every Town Hall. Each lab level unlocks a new tier of research, and the lab sits idle while it is being upgraded, so getting it done early costs the least research time.
Clan Castle next, then Army Camps. More and stronger reinforcements, then more housing space, raise every attack you make.
Workshop as soon as it unlocks. A low-level siege machine dies to defenses that a higher one walks through.
Barracks and Spell Factories only for an unlock you want. Upgrading them does not raise any troop's level.

Max-out Cost at Town Hall 18

Showing every level (TH18 is the current max)

Maxing all army buildings at Town Hall 18 from level 0 takes 670 builder-days and 1,048,546,900 elixir.

Builder-days are the summed upgrade time of every copy for one builder; divide by your builder count for a calendar estimate. No boosts, gems or helpers. “From the previous cap” assumes everything was at the TH17 TH Cap before you upgraded. Full Max-out Cost calculator
