Budget plan

Income <----------------------> Expenditures

Expenditures:

- Fixed costs

- Non recurring high charges

I bought a new car for € 12.000,- and expect to buy a new one in 8 years. The price will probably be 15% higher then. The trade-in value will likely be € 2.500,-. How much should I put in my monthly budget plan?

Answer

12.000 x 1,15 = 13.800

13.800 - 2.500 = 11.300

11.300 / 96 = 117,71
