Key Takeaways

The Builder Barracks has 12 troops, all researched with Builder Elixir in the Star Laboratory, and every one maxes at level 20 at Builder Hall 10.
Maxing all twelve takes 391,895,500 Builder Elixir and 565d 6h 3m 30s of Star Laboratory time, about a year and a half with one lab and no boosts. That is 150 paid upgrades.
Each Builder Hall raises the troop cap by two levels: level 4 at BH2, level 6 at BH3, and so on up to level 20 at BH10.
Troops unlocked later start higher. The Electrofire Wizard arrives at level 17, so it needs only 3 paid levels and 15,600,000 Builder Elixir.
BH8 to BH10 account for 301,200,000 Builder Elixir, 77% of the total. The last two levels of each troop cost 4.6 to 5.8 million and take 6 days 12 hours each.

All 12 Builder Base Troops: Cost to Max

Builder Elixir and Star Laboratory time from each troop's starting level to level 20, before boosts. A troop starts at the level shown when you unlock it, so those levels cost nothing.

Troop Research Added at Each Builder Hall

Each new Builder Hall lifts every troop's cap by two levels and adds the troop unlocked there. This is the research each hall opens, so you can plan the Builder Elixir before you upgrade it.

Builder Hall	Troop cap	New upgrades	Builder Elixir	Lab time	Running total
BH2	level 4	6	45,500	1h 3m 30s	45,500

BH10	level 20	25	132,000,000	162d	391,895,500

Lab time is for one Star Laboratory with no Clock Tower boost. The BH10 row is the biggest single step: 132,000,000 Builder Elixir and 162d.

Where the Builder Elixir Goes

Early research is almost free. Everything up to BH5 costs 21,295,500 Builder Elixir across all troops, under 6% of the total. The cost climbs fast after that because each new hall adds two levels to every troop you already have.

The most expensive troops

Cannon Cart (37,700,000), Baby Dragon (37,340,000) and Night Witch (36,600,000) cost the most to max. Raged Barbarian is the cheapest of the troops that start at level 1, at 32,720,500.

The last two levels

Level 19 and 20 of every troop need Star Laboratory 10 and Builder Hall 10. Together they cost between 9,800,000 and 11,400,000 Builder Elixir per troop and 13 days of lab time.

One lab, one queue

The Star Laboratory researches one troop at a time, so the 565d 6h 3m 30s total is calendar time if the lab never stops. Pick the troops you actually use first.

Planning Builder Base Troop Research

Keep the Star Laboratory running. With 565 days of research and one lab, any idle hour is lost. Start a long level before you log off.
Research your army first. You only take a few troop types into a battle, so max those before troops you never use.
Upgrade the Star Laboratory with the hall. Levels 19 and 20 need Star Laboratory 10, and that lab upgrade itself takes days, so start it early at BH10.
Use the Clock Tower on long research. The Clock Tower speeds up the Star Laboratory while it runs, so turn it on when a 6-day level is in progress.

On my Builder Base, Dark Knight (ID #82GY00YYQ), the Builder Hall is at BH10 and the defenses are close to max, but the troops are not. Seven are maxed at level 20: Bomber, Baby Dragon, Cannon Cart, Drop Ship, Power P.E.K.K.A, Hog Glider and Electrofire Wizard. Five are still behind: Raged Barbarian (level 14), Sneaky Archer (11), Boxer Giant (9), Beta Minion (4) and Night Witch (12). Maxing those five takes 50 more upgrades, 155,520,000 Builder Elixir and 231 days 14 hours of lab time.

My usual army is 3 Power P.E.K.K.A, 1 Bomber and 2 Cannon Carts, with 2 more Power P.E.K.K.A as reinforcements. That is why the P.E.K.K.A, Bomber and Cannon Cart were maxed first. The Battle Machine is maxed at level 35, and I bring the Battle Copter (level 22) into Stage 2 when I need it.
