Continuous improvement in purchasing

In vehicle trading, the best operator is not necessarily the one selling the most cars, but the one completing the most efficient deals. Every purchase introduces both economic and tax risk. The calculator turns three frequently misjudged factors into visible numbers:

  • The cost trap under § 25a Repairs reduce profit, but normally do not reduce the margin-scheme VAT base.
  • The EU dilemma An EU dealer receiving a § 25a gross invoice cannot deduct input VAT. Opting for standard taxation may produce the better transaction.
  • Cash flow versus profit A high gross return on paper means little if VAT is calculated from the wrong tax base.

Why calculation beats intuition

Common mistake

The gut-feeling calculation

“Buy for €10k, spend €1k, sell for €13k. That is €2,000 profit.”

Result: ignores the tax treatment.
Actual profit is often below €1,200.
