A live calculation on the same functions as the product
Change the bid, the country or the resale price. Exchange rates in the demo are fixed and logistics tariffs are typical, so the amounts show the mechanics, not an offer.

Calculation warnings: 3
- Rate "ua.registration_blanks_plates" is not confirmed by an official source — check before paying. Бланк свідоцтва 606 + номерні знаки 350 грн — лише вторинне джерело (hsc.gov.ua віддає 403).
- Rate "ua.registration_expert_examination" is not confirmed by an official source — check before paying. Сума 10.2% ПМ = 339.46 грн — з п. 36-3 КМУ 795, але обовʼязковість для вживаного імпорту і ПДВ на послугу НЕ підтверджено.
- Logistics and services use TYPICAL tariffs — replace them with your own in tenant settings.
Rules: UA@2026-01-01. Confidence in the calculation: 54%. Demo exchange rates and typical tariffs, not an offer; the resale price is your assumption (in the Pro extension this is a market estimate).

Questions
Frequently asked questions
Where do the numbers come from?
Auction fees come from the public Copart and IAA tables on the date checked. Customs rates come from dated rules with links to laws and official pages. Logistics and services use your tariffs; until you enter them, typical values are used and the calculation warns you about it.
How is margin calculated?
Margin is the difference between the sale price and the cost, divided by the sale price; markup is shown separately. The default verdict: 15% and up is good, 8% and up is acceptable, 0% and up is risky, below that is not worth it. You can change the thresholds.
Does it work on auction pages?
The extension is being built for Copart and IAAI lot pages; selectors are tested against saved pages. Auctions can change their layout, so we have to update selectors after changes. We are not affiliated with the auctions.
What about zero duty for US cars in the EU?
The calculator accounts for EU Regulation 2026/1455 on the Polish, Lithuanian and German routes: 0% duty applies only to cars assembled in the US, with proof of direct transport. The calculator suggests the country of origin from the VIN, but documents are still required.
Calculate margin before the bid, not after
The first 14 days are free, then from $29 a month.
