TIL you can get past the minimum coring cost on a province if you have a permanent claim.

I think its the admin efficiency actually. 300 * (1 - 0,40) * (1 - 0,25 - 0,10 - 0,25 - 0,25) = 27

Noob question, what is administered efficiency (besides the obvious 60% coring cost discount, guess I just answered my own question there lol) and more importantly how do I get it?

"Administrative efficiency is a country wide bonus that starts at 0% and increases by 20% at administrative technology level 17, 23 and 27, up to a total of 60%. Administrative efficiency directly reduces core creation and diplo-annexation costs. It also reduces the impact of province development on overextension and warscore cost, allowing for much larger territories to be conquered at once. " - EU4 wiki

So that's how people are able to blob to such ridiculous fucking extents by endgame

You don't even need the permanent claim! Here's me getting 13 cost for 21 development with a regular claim.

Is the "minimum" even a thing any more? Seems like not.

Hmm it seems like when they made the coring cost reductions multiplicative, it somehow screwed with the minimum base.

The coring cost reduction from the following stack multiplicatively:

Overseas provinces (-50%)

Non-overseas colonies (-50%)

Same colonial region/same continent for colonial nations (-75%/-25%)

Admin efficiency (-20%/-40%/-60%)

All other reductions stack additively. The minimum coring cost is 10% after the above reductions.

OP's case: 30 * 10 * (1 - 0.40) = 180 base cost with a minimum of 18, 180 * (1 - 0.25 - 0.10 - 0.25 - 0.25) = 27 actual coring cost.

LWMR's case: 21 * 10 * (1 - 0.60) * (1 - 0.50) = 42 base cost with minimum cost of 4.2, 42 * (1 - 0.33 - 0.25 - 0.10 + 0.002) = 13.524 actual coring cost

Mind elaborating a bit more on this? This has me intrigued. May have to do some testing based on your elaborations.

Basically can you explain how the multiplicative and additive coring reductions interact with each other? Be as detailed as you want/can. If I struggle to follow along I'll make sure to ask questions.

Thanks a ton if you elaborate more for me!!!

It is basically as I stated above, most reductions are additive while a few are multiplicative. The multiplicative reductions are applied first and as far as I know it is this cost that is used for calculating minimum coring cost, overextension, province warscore cost, religious unity etc. I am not 100% on the latter three, but at least coring cost. After the "base" coring cost is calculated the rest of the reductions are applied additively. This is all the "normal" core-creation reduction stuff: have claim/permanent claim, national ideas, adaptability idea, HRE reforms, reductions from religions and government forms, etc. The minimum coring cost of a province is 10% of the earlier calculated base and the maximum is the base of a 30 development province (provinces above 30 dev counts as 30 dev, as seen in OP's case).

So for a 24 dev province while playing as Italy (-25% coring cost) with the Adaptability idea (another -25%), a claim (-10%) and 40% admin efficiency, the calculation becomes:

24 (development value) * 10 * (1 - 0.40 (the admin efficiency)) = 144 base cost

The minimum cost for this province is 10% of that, 14.4. Then we apply the additive reductions:

144 * (1 - 0.25 * 0.25 * 0.10)

144 * (1 - 0.25 - 0.25 - 0.10) = 57,6 final coring cost

Admin efficiency can reduce it to below 1 ADM per dev. Admin efficiency is the only multiplicative core creation modifier iirc, everything else is additive. If you didn't have admin efficiency in this pic you'd be paying 1.5*30 = 45 admin to core it.

Overseas, same continent colonies, same region for colonial nations, and same continent for colonial nations are also all multiplicative.
