Why are these calculators free?
Because every fleet manager faces these three questions.
TCO, perk tax and CO₂ are the three numbers asked in every C-level meeting. We want you to have them in five minutes — not in days of Excel work.
Because GDPR-friendly means local computation.
All inputs are processed exclusively in your browser. No server transmission, no calculation-related cookies, no tracking of results.
Because DKV InstantFuel provides the data backbone.
Once you’re on DKV InstantFuel, the data for all three calculators is clean in a single dashboard — no manual upkeep, no after-the-fact receipt sorting.
