How to improve your financial index?

How do you improve it? My currently 150.67. I want to improve mine to at least 200

Pro tip: (because I feel nice today)

Once your outgoings/expenses as on your overview of the months profit loss go over 100B a month, providing you are still keeping a healthy income compared to that (and 150 shows a healthy income) then another formula for calculating the FI kicks in and your FI can rise substantially higher.

Shh!

J/k, good tip.

Also remember that the FI works over time, a steady increase in FI month on month can alo result in a jump at the turn of each game year.

Whats FI?

Financial Index. Any relation to American Dad?
