Really simple economic math bug

Taxes percentage is REDUCING my income not increasing it

Hey Stardock - I did do a quick search first before posting - hard to believe nobody else has mentioned this simple math bug in the Economy screen.

In my screenshot you can see:

GDP = 4,352.68
Trade route income = 488.99
Taxes are set at 25% (assuming this is a 25% income multiplier?)

So my total income should be 4,352.68 + 488.99 * 1.25 = 6,052.08

BUT - the 25% rate is being applied as reducing factor:

4,352.68 + 488.99 * 0.25% = 1,210.42

So I'm losing nearly 5000 credits per turn!

Your math is wrong. It's 25%, not 125%....so should be .25, not 1.25 you are multiplying it by.

Yeah, not a bug, working as designed. Your 2nd calculation is how it works. You only get to keep the taxes not the total income. The taxes represent your Civs income - everything else is kept by the citizens. Additionally, raising taxes lowers morale/happiness and lowering taxes raises it. Actually kind of realistic if you stop and think about it.

Hmmm...yeah, I guess so. I think the UI could be more helpful in that case...

Agree with that. Took me awhile to get used to it once I figured out what was going on.

Hey, taxes function similar to how they would in our world.
As government you set tax bracket for your empire GDP. So you can raise the tax bracket, to get more income, but it will never exceed the 100%.

Income you get from a credits-per-turn treaty should not be multiplied by the tax, though.

I Totally agree with that. That's like the government taxing itself. After all the treaties are not between citizens and foreign Civs.

It makes receiving per-turn credits pretty useless, but-- if you can successfully offer an AI a per-turn deal (when you're at 95% prestige would be a good time....), it can be good for you. You end up not helping them. It's a broken mechanic, but that's how you would play it. It is what it is.

Just to be clear, this thread is not all a nothingburger. It's not just a UI issue. Per-turn credits deals are being multiplied by your low tax rate, while I believe the AI is being deducted the full amount. Which I find hard to believe is by design. h

I basically think of it as a small boost to my income and a way to economically cripple all my future enemies
