TRANSPARENT MATH

Calculation steps

  1. Purchase price is not counted in full: resale value is deducted.
  2. All running costs are summed over the selected holding period.

Substitution with your values

Sum of displayed components A = 18000.00 + 9712.50 + 5850.00 + 5250.00 + 3200.00 = 42012.50Sum of displayed components B = 24000.00 = 24000.00Total: 42012.50 / 18000.00
