It needs to be determined what formulas are no longer accurate
This page contains a listing of various formulae for Earth Empires.
Basic Formulae
Please note, a lot of these are old formulas, and need to be updated. This list does not include every formula either. Those highlighted in green are as accurate as possible.
Earth is a game of numbers and formulas. So here they are:
| Calculating | Formula |
|---|---|
| Per Capita Income (PCI) | 22.5 * (1 - Taxrate) * (1 + ((Networth/Land)/90000)) * (1 + (2 * (Ent/Land))) * BusTech * GvtPCIBonus |
| Revenue | PCI * Pop * Taxrate |
| Construction Cost | 3 * Land + 1500 |
| Destruction Cost | 0.2 * (3 * Land + 1500) |
| Rebuilding Cost | |
| Oil Consumption | (Troops + Jets + Tanks)/25 |
| Buildings Per Turn | (CS/4 + 5) * GvtContrBonus |
| Military Upkeep | Troops Upkeep: Troops * .11 * MilTech% * (1 + Networth/40000000) * GvtBonus * Constant Jets Upkeep: Jets * .14 * MilTech% * (1 + Networth/40000000) * GvtBonus * Constant Turrets Upkeep: Turrets * .18 * MilTech% * (1 + Networth/40000000) * GvtBonus * Constant Tanks Upkeep: Tanks * .57 * MilTech% * (1 + Networth/40000000) * GvtBonus * Constant Spies Upkeep: Spies * 1 * MilTech% * (1 + Networth/40000000) * GvtBonus * Constant Constant = If MilBases/Land < .295 Constant = 1 - 1. 3 *(MilBases/Land) Else (that is, if the number of MilBases built is more than 29.5% of your land) Constant = 0.61 |
| Alliance Costs | Defensive Allies: DefAllies * Networth * 0.002 (0.2% of NW each) Offensive Allies: OffAllies * Networth * 0.002 (0.2% of NW each) Intelligence Allies: IntelAllies * Networth * 0.0015 (0.15% of NW each) Research Allies: ResAllies * Networth * 0.0015 (0.15% of NW each) Trade Pacts: TradePacts * Networth * 0.0005 (0.05% of NW each) GDI Costs (Theocracy): Land * 8 GDI Costs (All Others): Land * 4 Declare War Costs: Land * 10 |
| GDI Penalty | Because of the defensive nature of the alliance, one side effect of GDI is 10% lower gains from your attacks. |
| Land Upkeep | Land Upkeep = (Land ^ 2) * (7/1500) + (Land * 3) |
| Total Expense | Military Upkeep Costs + Alliance Upkeep Costs + Land Upkeep Costs |
| Networth | (Troops * 0.5) + (Jets * 0.6) + (Turrets * 0.6) + (Tanks * 2) + (Spies * 1) + (Tech * 2) + (Land * 45) + (Buildings * 35) + (Money / 20000) + (Food/1000) + (Missles * 2500) + (Pop/6) + (Oil/100) |
| Food Production | (Farms * 5.3) + (Unused Acres*0.4) * GovFoodBonus * AgriTech |
| Food Consumption | (Pop * 0.03) + (Spies * 0.005) + ((Troops + Jets + Turrets) * 0.001) + (Tanks * 0.003) |
| Food Decay | Bushels * 0.001 |
| Technology Percentages | BaseTech + (MaxTech - BaseTech) * GovtBonus * (1 - Exp(-Effective * TechPoints / (C1 + (C2* Land)))) See techology for more info |
| Military Formulas | |
| SPAL (Spies Per Acre Land) | (Spies*GovtBonus*Spytech + 1/4 AlliesSpies)/Land |
Most formulae use standard rounding, but some, like networth, use truncation.
Note: A good player does not have to know all the formulas.
