How much money required to run a successful NCB (in General)

I was just wondering about how much money is now required to run a successful NCB. By that i mean reaching at least 3mil MPR, and also not hiring any minions along the way. I was thinking around 50mil would be needed but i was just wondering if that has changed due to the increase in length of the NCB.

3m mpr could likely be reached with that amount or less

Tank or Mage?

I will end up around 3m MPR with no money spent on BA, assuming I can keep at least close to my current growth level.

with the increase in length, you'll be actually get getting much more money to spend on BA.

50 million is plenty, you can buy BA for probably around halve to 3/4ths of your NCB with that amount of cash, just make sure you're not neglecting the use of your own equips.

I got to 2.6 mil without buying BA. I missed a lot of BA though. You should be able to get to 3 mil easy if you don't miss any, without spending cash.

as of tonight, my ncb is 6 weeks old. i have missed little if any ba and started with almost 1600. i broke 1m mpr this afternoon.

i will have to see how much i slow down as the challenge bonus decreases, but i also believe that 3m would be doable with no purchased ba and little missed of your natural regen.
