Enter the monthly total of your lease or purchase 
payments, vehicle insurance, registration fees,
normal maintenance, fuel, public transportation,
parking and tolls for one month.  

To calculate the monthly amount for registration,
divide your annual registration by 12.  

For calculating the monthly insurance cost, if
your carrier issues 6-month policies, divide 
the total by 6.  If you receive an annual policy,
divide the total premium by 12.
