Full bio →The Two Dominant Salvage Auctions
Copart and IAA (Insurance Auto Auctions, now branded simply as IAA) are the two largest salvage and insurance auto auctions in the United States. Both sell total-loss, salvage-title, and clean-title vehicles sourced from insurance companies, fleet operators, and dealers.
Choosing between them usually comes down to which auction has the vehicle you want — but knowing the fee differences helps you budget accurately on each platform.
Buyer Fee Comparison
Both auctions use tiered flat-fee structures up to a threshold, then switch to percentage rates for higher bids.
Bids Under $5,000 — Secured Payment
| Bid Amount | Copart Secured | IAA Secured | Difference |
|---|---|---|---|
| $500 | $200 | ~$185–$205 | ≈ even |
| $1,000 | $355 | ~$325–$360 | ≈ even |
| $2,000 | $500 | ~$475–$510 | ≈ even |
| $3,000 | $650 | ~$620–$660 | ≈ even |
| $5,000 | $775 | ~$740–$790 | ≈ even |
Bids $5,000–$15,000 — Secured Payment
| Bid Amount | Copart Secured | IAA Secured | Difference |
|---|---|---|---|
| $7,500 | $825 | ~$800–$860 | ≈ even |
| $10,000 | $900 | ~$890–$960 | ≈ even |
| $14,999 | $900 | ~$900–$980 | ≈ even |
| $15,000+ | 7.5% | 7.5%–8% | ≈ even |
Takeaway: Buyer fees at Copart and IAA are nearly identical across all bid levels. The difference is typically under $50 at bids below $10,000 — not a meaningful reason to prefer one over the other.
Unsecured Payment Comparison
Both auctions charge significantly more for credit card and digital wallet payments.
| Bid Amount | Copart Unsecured | IAA Unsecured |
|---|---|---|
| $2,000 | $620 | ~$600–$650 |
| $5,000 | $1,025 | ~$990–$1,050 |
| $10,000 | $1,250 | ~$1,200–$1,300 |
| $15,000+ | 12.5% | 12%–13% |
Again, nearly identical. Use secured payment at both auctions to minimize fees.
Virtual Bid Fee Comparison
| Feature | Copart | IAA |
|---|---|---|
| Pre-bid fee | $0–$129 | $0–$129 |
| Live bid fee | $0–$149 | $0–$149 |
| In-person bid | None | None |
Virtual bid fees are essentially the same at both auctions.
Gate Fee Comparison
| Vehicle Type | Copart | IAA |
|---|---|---|
| Clean title | $79 | ~$85 |
| Salvage title | $95 | ~$85–$95 |
IAA’s gate fees tend to run slightly lower for clean title vehicles at some locations. Copart’s salvage gate fee ($95) is at the high end of IAA’s range.
Storage Fee Comparison
| Feature | Copart | IAA |
|---|---|---|
| Free days | 3 business days | 3 business days |
| Storage rate | ~$25–$40/day | ~$25–$40/day |
| Late payment fee | $50 | $50 |
Storage policies are functionally identical between both auctions.
Membership and Access
| Feature | Copart | IAA |
|---|---|---|
| Basic membership | Free (public bidder) | Free (public bidder) |
| Premier membership | ~$400–$800/year | ~$400/year |
| Dealer license required | For some title types | For some title types |
IAA’s premium membership tends to be slightly less expensive than Copart’s for equivalent access tiers.
Where Copart and IAA Actually Differ
Inventory Size
Copart is the larger platform — it typically lists more vehicles at any given time. IAA tends to have strong inventory in late-model insurance total-loss vehicles from major carriers.
Geographic Coverage
Both operate nationwide, but specific vehicles are only at specific yards. A vehicle 800 miles away at a slightly lower buyer fee is almost never worth the transport cost difference over a nearby vehicle.
Platform Reliability
Copart’s online bidding platform has a long track record of stability. IAA’s platform has improved significantly but can still experience slowdowns during high-volume auctions. For high-value or time-sensitive bids, platform reliability matters.
Title and Documentation
Both auctions provide title documentation post-purchase. Copart titles generally process faster at most locations. If you’re in a state with strict title transfer timelines, ask the specific yard about processing times.
Which Is Cheaper?
For most buyers bidding under $10,000 with secured payment, the total cost difference between Copart and IAA on equivalent vehicles is under $50–$100. That difference is easily erased by a single extra storage day or a slightly higher bid at the other platform.
The real cost variables are:
- Transport cost from the yard to your location — this can be $300–$1,500 and far exceeds any fee difference
- Payment method — using credit card vs wire transfer adds $60–$350 in buyer fees regardless of which auction
- Storage days — missing the 3-day free window costs $25–$40/day at both platforms
Choose based on inventory, not fees. Buy the vehicle you want at the auction that has it. Use the Copart Fee Calculator to calculate your exact Copart total before bidding, and IAA’s fee estimator on their site for IAA vehicles.
