Total Expenses and Income calculations

[rachelrring]

It seems maybe the way the totals are calculated is wrong somehow. I only noticed in passing while working on a different feature.

Will look in to later

When I enter:

• pay after tax: 10 weekly
• benefits: 10 monthly
• pension: 10 yearly

the total income displayed should be: (1052)+(1012)+(10*1) = 650.

However, it displays €640100
