Quick briefing before auction day. IAAI buyer fees decide whether a deal is a win or a loss. Fees are tiered by purchase price and vary by license type, buyer volume, and facility — there is no single public schedule that fits every account. This guide shows how to bake fees into max-bid math, watch title risk, and verify numbers on the lot cost calculator before you bid.
Core idea — Bake fees into the max bid
Don’t treat the hammer price as the final cost. IAAI charges a buyer fee that changes as the hammer crosses price bands, plus service/gate and other line items that vary by facility. Your max bid must include buyer fees, service charges, transport, and a repair buffer. Do that math before you click "place bid." If you want a deeper breakdown on how poor max-bid math inflates costs, calculate the true cost of a bad max bid: calculate the true cost of a bad max bid.
1) How IAAI fees actually work
IAAI publishes buyer-fee schedules by buyer type (licensed, non-licensed, heavy, Rec Rides, and volume tiers). Exact dollar bands change and differ by account. Treat any third-party “exact schedule” as suspect unless it matches what your logged-in IAAI cost calculator shows for that lot.
- Open the Vehicle Details page while logged in and use IAAI’s Cost Calculator for the specific lot.
- Expect separate line items: buyer fee, service/gate, environmental, title handling, and sometimes virtual/internet bid fees.
- Broker buys add the broker’s fee on top of IAAI’s charges.
For planning before you have a live lot open, AutoFlip’s free IAAI fee calculator applies approximate planning estimates (often in a ballpark effective range near 8–13% of hammer on mid-range lots). Those are estimates only — always verify on the lot calculator and final invoice.
Small hammer jumps can push you into a higher fee band and add meaningful dollars instantly. That kills thin-margin flips. When the numbers are borderline, consult guidance on when to walk away at salvage auctions.
2) Max bid math — exact for your account, not wishful
Set a strict max bid. Work backward from your target leave-for-profit number.
Steps:
- Estimate ARV (after-repair value) conservatively based on comps in your target radius.
- Subtract your repair estimate and sales costs to get a target purchase price.
- Pull buyer fee + service/gate (and other line items) from the IAAI Cost Calculator for that hammer — or use a conservative planning estimate and pad upward.
- Factor in transport and title work – use a conservative transport range and assume the high end until you prove otherwise.
Concrete planning example (illustrative only — replace with your lot calculator numbers):
Say you plan on a $1,000 hammer. A conservative planning stack might put combined IAAI buyer + service charges in the mid-hundreds (not a tiny flat fee). Published transport ranges for domestic moves are often broad; use a conservative range of $500–$1,500 for planning until you have a carrier quote. See common transport cost mistakes that shrink your max bid.
Example planning math: $1,000 hammer + ~$300 auction fees (placeholder) + $500–$1,500 transport = roughly $1,800–$2,800 before repairs, tax, and title. Replace the ~$300 placeholder with the Cost Calculator total for your buyer type. Don’t guess cheaper just to justify an emotional bid.
3) Title risk and paperwork traps
Title status kills deals. IAAI listings sometimes show "clean," "salvage," or other state flags. Treat ambiguity as a red flag. If title work or reissue is likely, build in a title-handling buffer. Expect states to have variable title fees; don't count on cheap or instant re-titles.
Common traps:
- Listings with mismatched VIN notes. If the VIN is partial or flagged, expect title delays.
- Previously out-of-state vehicles with salvage brands. Some states require rebuilt inspections that add time and costs.
- Broker layers. If you buy through a broker, they will add their fee on top of IAAI’s fees. Treat broker costs as mandatory, not optional.
Also review salvage title history red flags to watch to spot messy VIN and branding issues early. Rule of thumb: if paperwork looks like it will take more than two weeks or needs significant re-issue work, either pass or cut your max bid by your worst-case title cost estimate. Don’t assume you’ll fix title for free.
4) Repair spread — what you must assume
Don’t under-estimate mechanical surprises. When you budget repairs, assume the job will find one unexpected item. That usually eats your thin spreads.
Two practical points:
- Use a conservative labor-rate assumption for your market. If you don’t have a shop rate, assume higher than the going rate when you first start bidding.
- Reserve for parts lead time. A missing part can push storage and transport days, and those costs add up fast. See common salvage repair cost surprises.
Example application: if your ARV math only gives you a $1,000 cushion between purchase+auction fees and expected sale, you’re not safe. Move on or renegotiate your numbers.
5) Auction day behaviors that cost you money
Two bad habits that show up often:
- Chasing a car past your max because you want it. Every extra $100 over your max needs to be justified by documented upside. If you can’t show that upside in comps, stop. If you’re unsure whether to stick to a number, check 7 signs you're overbidding at salvage auctions.
- Forgetting fee-band cliffs. Bids that cross into a higher fee band without adjusting your max are how flippers lose money. Watch thresholds on the Cost Calculator as the hammer climbs.
Also, pre-calculate fees for vehicles you track using the lot calculator or a conservative planning estimate. Don’t rely on memory at the last second.
Mini case: Small sedan, tight margin
Use this template on a morning run list. Replace fee placeholders with your Cost Calculator output.
- Hammer target: $1,000.
- IAAI fees (buyer + service/gate + other line items from Cost Calculator): enter the live total — do not invent a schedule.
- Transport planning: use $500–$1,500 until carrier quotes are in.
Work the numbers: hammer + live IAAI fee total + transport high end + repair/title buffers + desired profit. If expected resale doesn’t cover that stack, skip the lot.
Where a salvage flip tool helps
Use a max-bid calculator to avoid accidental overbids and to keep thin spreads from disappearing when fees stack. AutoFlip Pro's Max Bid Calculator combines clean market value, title discount, transport, auction fee planning estimates, repair cost, profit margin, and a risk adjustment so you can see the true max bid before you enter a lot.
- Applies planning fee estimates you can override with your invoice/Cost Calculator numbers.
- Includes transport and title adjustments so you don't forget hidden costs.

Key takeaways
- Always include IAAI fees from the lot Cost Calculator (or a padded planning estimate) in your max bid before you bid.
- Watch fee band thresholds — small hammer increases can add hundreds in fees.
- Use a conservative transport range until you get an exact carrier quote; budget the high end.
- Assume paperwork delays; title issues are the most common profit-killer.
- Set a hard walk-away number and don’t chase in the heat of the sale.
FAQ
Do IAAI buyer fees include environmental or gate fees?
Not always as one line. Buyer fee is only part of the stack. Service/gate, environmental, title handling, and virtual bid fees can apply depending on lot and facility. Pull the full Cost Calculator total for that vehicle.
How do I handle broker fees?
If you use a broker, their fee is on top of IAAI’s fees. Always ask the broker for a full breakdown and add it into the max bid math. Do not bid until you’ve confirmed the broker's total charge.
What if the car crosses a higher fee band while I’m bidding?
Stop and recalculate immediately. Re-check the Cost Calculator (or your planning estimate) at the new hammer. If the new total kills your margin, walk away.
Can I get a refund of buyer fees if I don’t pick up the car?
Refund policies vary and tend to be strict. Don’t rely on refunds. Your planning should assume fees are non-refundable once the car is awarded.
What’s the fastest way to avoid fee surprises?
Pre-calc fees for every lot you watch using IAAI’s Cost Calculator while logged in. Keep a max-bid template that adds fees + transport + repair buffer + profit. If a lot doesn’t clear your template, skip it.
Actionable checklist (print and bring to the sale)
- List lot numbers and pull live Cost Calculator totals for each (or pad a planning estimate upward).
- Write your walk-away max bid that already includes those fees.
- Get a transport quote or plan on the high end of a $500–$1,500 planning range.
- Confirm title flags on the VIN; if unclear, reduce max bid for title risk.
- Do not bid without your final numbers in front of you.
Bring the checklist. Bid cold. Win clean.
