Average Income? (Game End Screen)

On my last game, my average income was -70bc or so, and yet I finished with more money than I started with. How is this possible?

Because its not taking: final $ - initial $ / number of turns. Its averaging your income for each game turn. This means you had a lot of turns with negative income.

(final$ - initial$) / #turns = average = (Turn1$ + Turn2$ Turn3$ ...+TurnN$)/ nturns

horay for math.

Average is path independant operation. (kind of like gravity and work, and not like friction and work).

So you can take individual points along the path and add them together then divide or just doing it final- initial value.

Since the integral of time Vs income graph is given in units of $ since income is $/turn and time is messure in turn.
Then we can take the ine integral of the function from a to b divided by b-a which is the number of turns.
Also you can take the intial and final values of $ and divide by turns.
Both of these should be =.

But that is only true if there is no outside factors in the $ value.
Such as donations, anomlies with cash, or small civs. paying you off..
If you take that out then they should be equal.


So what this means is that
Initial$ + AverageIcnome(numberofturns)+gifts/anomolies/payoffs = Final$

so if average income < 0, and final >intial then gift >0

Thurlin, That doesn't make any sense. If you average a negative value then you have to end up with a lower amount of money than what you started with. The only way that could be the case is if the calculation doesn't take into account certain types of "income" (perhaps only tax income is counted)

I've seen this too but decided that it would be too much work to figure out how it's calculated.

Gifts are not calculated into income. Neither are anomolies or buy offs. Upgrades or destroying ships for cash.

Tax income is the only thing counted on that calculation. Even freighter revenue is not counted.

It is only counting tax income. Other sources of income would include: trade from freighters, tourism, tribute/gifts, selling techs, etc.

Thank you. Thats what I meant but I couldn't get back in to edit the message.

OK, it's only counting tax income - that's the positive #.

What expeditures is it counting?

it counts all expenditure, and income i would say. at the end of my last game, i got bored and decided to set production 100% 80% research and did tech victory in a few turns, but it was costing me like 10000bc each turn, at end i had average income of -4732 bc. the game didnt last very long anyway

Also keep in mind average income doesn't reflect the "free bail-out" you get on lower difficulties when you drop below -2000bc.
