How to find out upgrade cost of a unit

[CppMaster]

Hello,
where can I find information how much gold would upgrade of a unit cost without any reduction when I haven't unlocked it? I wanna know how much gold should I save to when I unlock it. I couldn't find it in ingame civilopedia.

I speculate that you can get it from Defines. Maybe someone will correct me on it.

I think the variables we care about are:
BASE_UNIT_UPGRADE_COST = 10
UNIT_UPGRADE_COST_EXPONENT = 1
UNIT_UPGRADE_COST_PER_PRODUCTION = 1
UNIT_UPGRADE_COST_VISIBLE_DIVISOR = 5

The way I understand is that:

(Upgraded production - Old production) * 1 + 10 [With everything rounded to the nearest multiple of 5 so a 0 or 5]

where Upgraded production is the production cost of the better unit and Old Production is the production cost of the previous unit. This is why Longswordsman cost less to upgrade to Tercio than Pikeman.

Seems to also be * (1 + 0.3 * upgradedUnitEra)
