Economy: settlement income calculation

[Lord Maximus]

I'm trying to find out how settlement (city/castle) income is calculated. Is there anyone here who knows?

I'm guessing each Settlement has some base stats which are multiplied with factors based upon buildings, traits & tax.
I've inspected most of the *.txt files but was unable to found these "base" stats.

I want to use those stats to build a small application which can be used to calculate income development over a period of time to determine the best upgrade/building planning for each settlement.

Any thoughts/ideas?

Two marginally-useful ideas:

Go directly to Creative Assembly and see if they'll make the data available. They've been pretty good about opening up a lot of the other data.

If that doesn't work, you can probably get a decent approximation by reverse-engineering it. Take a saved game and follow one city turn-by-turn. Measure the changes in both input (such as population and new buildings) and output (gross income). You should be able to isolate the change caused by each factor.

Not a bad idea. I've made an excel sheet which i use to track a few settlements turn by turn.

If you ever end up doing that, please post the results. I, for one, would be very interested in the results.

As would I.

I have noticed that often times, the economic gain for building a road or port isn't displayed properly. For example, I am making 100/turn on trade and I set a paved road to be built. It will display a gain of say 200/turn for 300/turn total. Then AFTER its built, the trade jumps up by a lot more than the projected gain. Its even worse with ports. They show almost no potential gain but it always seems to help greatly after its built. It would be really nice to know what's going on here.

It would also be nice to have some ballpark estimate of how much a probince would be worth if it were converted from castle/city.

Max--

I'd like to see any results as well.

Kawligia--

I'm wondering if the number you're seeing initially is, perhaps, a nominal value while the final value is adjusted for all other factors. For example, building a road has a base value of 100 kazoomies (or maybe 10% of total income) but once it's built, that number is modified by the governor's traits (such as good trader or superterrific administrator) and other already-constructed economic buildings.
