We have then, $26,830,797 - $3,199,504 = $23,631,393 of total revenue PRE staff, insurance and other costs not directly related to the airframe.
Doing maths: $24,047,184 - $3,147,368 = $20,899,816 of total revenue PRE staff, insurance etc, etc.
We know that the E190 is currently priced $11,606,410 higher than the An158. And the difference in revenues between both aircrafts is: $23,631,393 - $20,899,816 = $2,731,576. This means that the E190 will earn $2,731,576 MORE than the An158 in an year.
So we divide $11,606,410 / $2,731,576 per year = 4.25 YEARS.
That's the amount of time it takes to the E190 to balance the price with the An158. Going beyond that will make the E190 earn MORE than the An158.
I didn't take in consideration the engine commonality as I don't know the cost of the An158 engine.
Disclaimer: I know that the E190 carries more ppl than the An158, but as there was a comparison between them....
Disclaimer: I am brand new to this game, and haven't actually joined MT #3. I also bolded & fixed a typo, you put 26 million when you meant 23.
Since nobody sensible buys fleets of 1 plane, wouldn't it make more sense to compare revenue %? The An158 earns ~11.4% less revenue per year than the E190 according to your numbers. The thread doesn't mention actual plane cost, just that there's an ~11.5 million dollar difference. If it's an 11.4% increase, i.e. 100 million v 111.4 million, then you could spend $1 billion on 10 An158, and looking at ~210 million revenue per year. Or you could spend the same 1 billion on 9 E190, and be looking at the same ~210 million revenue.
If it's 200 million per plane v 211, then the E190 is going to come out ahead. If it's 50 million v 61.5, then the An158 will come out ahead, because even though a single E190 will show more lifetime profit after 5 years, an initial investment of 500 million will give you a fleet of 10 v a fleet of 8, and the 2 extra planes will outweigh the slightly higher profit of the E190.
Unless I'm missing something obvious.
I hope a new, full sized game starts relatively soon.
