You can see your profit champs top the list with a wide drop off after FE. They all follow the same general trend of an increasing % of the levelling cost being returned as rewards until eventually the 2.5% increase in total FP cost per level outstrips the reward FP growth (which i've never been able to come up with a precise formula for but is slightly faster than linear but slower at high levels than the 2.5% exponential growth of total cost). The ones that eventually become easy to get big profits off of have a notably higher % of the levelling cost returned as rewards all the way through. You can get a rough idea of the number you're looking for just looking at the level 10->11 stats for each building. Profit range from about Lv 38 to about Lv 60.ĭue to insufficient data GBs in the following ages have not yet been classified: It is evident that the GBs can be separated into 3 tiers: The top 3 GBs in descending order of profitability are: IT, Arc, Cape.

For clarity only the ratio for 1st place is shown, i.e., PR = P1/F1. Since at any given level, F is different for GBs in different eras, a fair comparison between the return on investment can be made by evaluating the profit-versus-lock-in ratio. The following table is a summary for locking in 1st place. The profitable range for 1st place is indicated as. The profitable range from L0 to L1 is different for each GB.įor the following graphs, positive means profit and negative means loss.Beyond that, a parabolic-like function takes over, turning loss into profit at some critical level L0, attaining some maximum profitability before dropping back to loss at another critical level L1.Profitability decreases (loss increases) rapidly for the first 10 levels (Lv 0-9).The profit or loss by locking in 1st and 2nd place is plotted as a function of GB level. Other GBs are not listed due to incomplete data, but GBs of the same era should have the same results (e.g., ToR should be the same as Obs). E.g., a GB in sticks is written as "Lv 0" instead of "Lv 0->1" on wikia.

The level of a GB is defined as the current level. Numbers for Obs, Zeus, CdM, Alcatraz, Cape, IT, Arc, AO, and Kraken are taken from wikia.
