Income

You can increase your money in multiple ways:

Per turn income
Planet & Race Mod Helper (Convert percentage to multiplier)

((Planet or Race Mod / 100) + 1) = Multiplier

Example Terran Agriculture Mod - ((20 / 100) + 1) = 1.2

Example Viral Commercial Mod - ((-30 / 100) + 1) = 0.7

Tax
Tax Formula

((Planet Population * (Planet Loyalty / 5000)) + (Planet Population / 2)) * Race Tax Mod = Credits Per Turn                                                                         Example - ((15,878 * (5,000 / 5000)) + (15,878 / 2)) * 1 = 23,817 Credits Per Turn

Commercial
Commercial Formula

(Planet Commercial * ((Commercial Research * 0.5) + 5)) * Race Commercial Mod = Credits Per Turn                                                                                Example - (10,000 * ((100 * 0.5) + 5)) * 1 = 550,000 Credits Per Turn

Agriculture
Agriculture Formula

((Planet Agriculture * ((Agriculture Research * 0.1) + 1)) * Race Agriculture Mod) * Planet Agriculture Mod = Food Per Turn                                          Example - ((10,000 * ((100 * 0.1) + 1)) * 1.2) * 1.2 = 158,400 Food Per Turn

Industry
Industry Formula

(Planet Industry * ((Industry Research * 0.1) + 1)) * Race Industry Mod = Goods Per Turn

Example - (10,000 * ((100 * 0.1) + 1)) * 1.5 = 165,000 Goods Per Turn

Mineral mining
Mineral Mining Formula

(Planets in Colony * ((0.13 * Mining Research) + 1) * Race Mining Mod = Minerals per turn

Example - (25 * ((0.13 * 10) + 1) * 1 = 58 Minerals per turn

Plunder planets
Plunder Formula

(([Planet Population * 2,500] + ((5,500 * [Total Planet Infra^2]) / Planet Land) + [200,000 * Planets in colony]) / 15) * Race Plunder Mod = Credits from Plunder

Example - (([15,878 * 2,500] + ((5,500 * [30,934^2]) / 30,934) + [200,000 * 25]) / 15) * 0.5 = 7,161,066 Credits From Plunder
