FAQ

Common Questions

Everything you need to know before your next bid.

It’s more than a spreadsheet. Decode a VIN to auto-fill the basics, apply Manheim, Copart, or IAAI buyer fees automatically, layer in state sales tax, and get your max bid ceiling with a full cost breakdown — usually in under two minutes.
You source and enter them yourself from whichever supplier you trust — Car-Part.com, eBay.com, LKQ Pick Your Part, new OEM, or aftermarket. AuctionCalc totals them instantly and factors them straight into your max bid.
No. AuctionCalc prevents blind bidding by giving you the real numbers so you can make an informed call — you still do the research and choose which vehicles to bid on.
No. AuctionCalc is an independent tool built to help buyers in the US and Canada estimate costs at Manheim, Copart, IAAI and OPENLANE auctions. We are not affiliated with, endorsed by, or sponsored by any of these companies.
Manheim doesn’t publish a single public buyer-fee schedule — fees are set per account, tier, and location. Rather than guess, we ship honest, clearly-labeled placeholder fields under the Manheim tab so you can enter your own account’s actual rates.
It depends. Licensed dealers with a valid resale/dealer certificate are typically exempt from sales tax at the point of auction purchase — tax is collected later when the vehicle is resold. The calculator defaults to tax-exempt; uncheck the box in Market Value if you don’t hold a valid certificate for this purchase, and it will apply your selected state’s statewide sales tax rate. On the Canadian calculator the same field applies your province’s GST, HST or PST instead.
It depends on whether you’re signed in. Signed out, your calculations stay in your own browser’s local storage and are not sent anywhere. Signed in, they’re saved to your AuctionCalc account on our servers so they’re waiting for you next time. We never sell your data and never share it with advertisers. One thing to know: saved deals can appear in Deal Hunter, the high-ROI feed available to Pro members — those entries show the vehicle, platform and deal figures, never your name, email or account.
They reflect each platform’s published Standard buyer-fee structure — Manheim, Copart and IAAI in the US, and Copart, IAAI and OPENLANE in Canada. Auction fees can change without notice, so always confirm current fees with your branch before placing a bid.
No — the core calculator is free to use with no account required. Enter your own figures and you’ll get your max bid ceiling, the full fee breakdown and your ROI. A free account adds VIN decoding, calculation history saved to your profile, and Deal Score; you’ll confirm your email address before those account features switch on. Paid plans raise your monthly VIN allowance and unlock the Chrome extension, portfolio tracking and Deal Hunter.
Every calculation you save gets a 0–100 Deal Score — 60% based on ROI (capped at 40%) and 40% on projected profit (capped at $10,000) — so you can tell an Excellent Deal from a Weak one at a glance. Switch the Recent Calculations list to “Best Deal” sorting to see your top-ranked saves first. It’s calculated entirely in your browser from your own saved history, free on every plan.

The US Salvage Auction Calculator for Manheim, Copart & IAAI

AuctionCalc is a purpose-built salvage auction calculator for the US used-car market. If you’re bidding on repairable vehicles at Manheim, Copart, or IAAI auctions anywhere in the country, AuctionCalc works out your true acquisition cost in US dollars — combining parts sourced from suppliers like Car-Part.com and eBay.com, estimated body-shop labor, each platform’s buyer-fee schedule, state sales tax, and transport back to your shop. The result is your max bid ceiling: the highest amount you can pay at auction and still hit your target profit.

Unlike a generic bid calculator, AuctionCalc applies damage- and theft-history adjustments to retail value, accounts for resale-certificate sales-tax exemptions that most licensed dealers qualify for, and decodes your VIN to auto-fill year, make, and model in seconds. Use it as your Manheim fee calculator, Copart fee calculator, IAAI fee calculator, and car-flipping profit estimator — all in USD, built for dealers and rebuilders bidding anywhere in the US.

AuctionCalc covers the Canadian market too. The Canadian calculator runs the same engine against Copart, IAAI and OPENLANE Canada, applies each province’s GST, HST or PST rather than US state sales tax, and works in the figures Canadian rebuilders and licensed dealers actually deal with — so a buyer in Ontario, Alberta or British Columbia gets a max bid ceiling built on their own costs, not a converted US one.
