If we invest everything in the ship's fund every month and make a 17% profit each month, we'll have 2.35 MCr when the bill comes due on 1111/001. Anything less than that and we won't make it, and it leaves us only 150 KCr to operate on, after the payment.
For us to never spend more than 50% of the ship's fund, we have to make between 23-24% profit on average, every run.
Stated differently, we have to make 184 KCr per month. Or, assume we alternate a week in J-space with a week in port(s) for a whole year, we have to make 84.7 KCr each jump. More if we have to slow down for any reason.
That tells me two things.
- We will certainly have to spend down the ship's fund to less than 50% its current value, more often than we'd like.
- We will have to mitigate that risk by taking other kinds of risk so we can receive bigger rewards.
