The buying calculator
Built for the moment the bidding gets fast.
Auctions move quickly, and it is easy to bid on instinct and discover the margin has gone when the invoice arrives. MarginRight works backwards from the profit you need, so you know where to stop before you start.
Enter the retail value and your costs, choose Margin Scheme or Plus VAT, and the calculator shows your maximum bid, projected profit, gross margin and return on investment together. You can save each appraisal and come back to it later.
Why dealers use it
Protect margin on every purchase.
Every cost in one place
Auction fees, prep, transport and VAT treatment are built into the number, not forgotten until the invoice arrives.
Margin Scheme and Plus VAT
Switch VAT treatment and see how it changes your bid, profit and return on the spot.
Profit, margin and ROI at a glance
Know what a deal is really worth before you commit, with a clear signal for whether to buy or walk away.

Step 1
Enter the deal
Retail value, current bid, auction fee, prep, transport and your VAT scheme.
Step 2

Built by a UK independent dealer.
MarginRight was created by an active independent motor dealer who buys stock at auction every week. It exists to solve one real problem: knowing exactly when to stop bidding before profit disappears.
