Cumulative Costs/Builder Base

==Summary==
The goal of this page will be to enumerate the total costs in time and to upgrade everything in the game at each Builder Hall level. In order to do this, some assumptions will have to be made:
#The costs of removing Obstacles will be ignored.
#The Buildings that get repaired during the tutorial will be excluded from Builder Hall 1's costs; similarly, buildings that exist when Stage 2 is established are excluded from Builder Hall 6's costs. The following is a list of buildings that are affected:
#*2x (1 in each stage)
#*2x (1 in each stage)
#*1x (stage 2)
#*1x (stage 2)
#*1x (stage 1)
#*1x (stage 2)
#*1x Builder Barracks (stage 1)
#*1x (stage 1)
#*1x Star Laboratory (stage 1)
#*1x Reinforcement Camp (stage 2)
#*20x (10 in each stage)
#*Technically, the Builder Hall and O.T.T.O's Outpost are pre-existing buildings when Stages 1 and 2 (respectively) are established, but since they do not have defined level 1 costs, they do not affect totals in any way.
#Since the tutorial can't be skipped, and due to the small amount of Builder Hall 1 contents, Builder Halls 1 and 2 will be merged, though costs and times incurred during the tutorial itself will be counted.
#Clock Tower boosts are not factored into upgrade times in any way; using them may reduce the real-time upgrade duration.
#Last Updated: The May 2023 "Builder Base 2.0" update.
==Calculators==
===Buying Builder Gold or Builder Elixir with Gems===
Calculations on this page assume that you always buy large amounts of resources at the maximum rate, therefore the cost of buying 1,000,000 Builder Gold is considered 700 gems rather the output of this calculator (1,200 gems).
===Buying Time with Gems===
===Buying Gems with $USD===
Calculations on this page assume that you always buy large amounts of chests of gems, therefore the cost of buying 6,500 gems is considered USD 46.43 rather the output of this calculator (USD 49.99 by buying a box of gems).
==Builder Gold Costs (excluding walls)==
This information is based on the number available to build and maximum level of each structure at each Builder Hall level. Walls have been separated from buildings because they are so expensive they distort the stats, and now that they can be upgraded with either resource at higher levels it makes sense to treat them separately. See the individual pages for a cost break down.

==Walls==
Walls can be upgraded to level 7 or higher with either Builder Gold or Builder Elixir, but the cost of either resource is the same.

==Time Costs==
Note that if trying to calculate Gem costs from the below, one cannot simply add up all the times and calculate the gem cost; instead the gem cost for each individual upgrade must be calculated and then summed together. This will cause the gem cost to be more expensive then simply putting the times into the time to gem calculator would indicate.
Star Laboratory Research times are separated from build times because there is only one Laboratory; overall research times will not be sped up by obtaining the second builder, O.T.T.O.
Also not that the Gold Pass time totals can be a little different from the actual time total, since the Gold Pass time totals use rounding.

===Decorations===
The cost to buy decorations are listed here, assuming that all decorations (that can be bought with in-game currency) are bought. However, they aren't considered in the grand total.
Decorations	Builder Gold	Gem
Total 	3,625,000 	750
===Daily Discounts and Special Packs===
If you decide to gem everything, then buying Magic Items from the Trader and the various special packs will save some money. Again, they aren't considered in the grand total.
Magic Item 	Gem Cost	Maximum Gem Cost if the effects are bought separately	Gems saved
Wall Ring 	50 	600* 	550
Book of Heroes 	500 	1,000 	500
Book of Building 	925 	1,616 	691
Book of Fighting 	925 	938 	13
Rune of Builder Gold/Builder Elixir	1,500 	4,133 	2,633
Clock Tower Potion 	75 	494** 	419
*This considers the cost of the level 10 Wall in Gems (1,200 Gems saved for 2 Wall Rings) instead of the level 7 Wall (the highest-cost Wall that uses only 1 Wall Ring, which costs 567 Gems).
**This assumes that both Builders and the Star Laboratory are all active, and that all resource production buildings are active, in which case 4h 30m is saved for each upgrader and the same time's worth of resources is produced for all resource producers. The value shown here is the gem value of the Builder Gold and Elixir produced, as well as the gem cost to save that amount of time per upgrader.

===Builder Time vs Lab Time===
With the introduction of O.T.T.O as a second Builder starting from Builder Hall 6, it is thus helpful to provide a comparison of how two builders will compare against a Star Laboratory when all three are kept active.
Although the two are fairly even up until Builder Hall 3, builder time greatly exceeds lab time at higher levels, even when accounting for having two builders. It is thus inefficient lab-wise to completely max out buildings and heroes before beginning a Builder Hall upgrade, since that will guarantee downtime on the Star Laboratory. On the other hand, it allows players to let their Lab to be idle for a time to commit to other Builder Elixir upgrades, such as for Army buildings or Heroes.
The "Normalised Builder Time" column is equal to the total Builder Time prior to BH 6, and equal to half that time from BH6 onwards; this equals the time it would take to upgrade all buildings if all builders are perpetually active.
