Goal of this application is to equalize expenses of all persons.
For example, two guys (Mike and Jimmy) want to drink a beer at home. Mike went to a shop and buy two bottles of beer and spent 60 dollars (it's very expensive beer).
The $60 price is High for Mike. He wants to split it with Jimmy to not be left without money.
So. Both guys have the same shares in this budget -- 50%. Mike have $60 expenses. Jimmy -- $0 expenses. That is, monetary shares of each guy = $30 (totalExpenses * share)
We need to equalize own expenses and monetary shares for each person.
By this example, funds of
Mike = 30 - 60 = -30
Jimmy = 30 - 0 = +30
Funds calculated by this formula:
Funds = shareInMonetary - ownExpenses [ + incomeTransactionsTotal - outcomeTransactionsTotal ]
To make funds of each persons equals 0, we can follow two ways:
- Reduce monetary share of Jimmy to 0 and increase for Mike to 60.
But this way Mike will become drunk. - Reduce expenses of Mike to 30 and increase for Jimmy to 30.
I think, Jimmy will like second way. So how to change expenses?
Easy! Jimmy should give $30 to Mike. In other language, we
need to create a transaction from Jimmy to Mike with 30 dollars total.
After transaction has been proceeded, let's recalculate funds for beer-guys.
Mike = 30 - 60 + 30 - 0 = 0
Jimmy = 30 - 0 + 0 - 30 = 0
Funds are equalized and now guys are happy.
