Auction Software Cost Calculator: Compare Fees vs. Flat Rate
Stop Paying the “Success Tax” on Your Auctions
Most auction software charges you more when you succeed. Use this calculator to see exactly how much profit you are losing to commission fees—and how much you could keep with Selling Lane.
Legacy auction platforms don't just charge you once; they often penalize you three different ways. We call this the Triple Success Tax:
- The Platform Tax: They take a percentage of your total sales (Hammer Price). The more you sell, the more they take.
- The Buyer Tax: They tack extra fees onto your winning bidders (Internet Premiums). That is money that should be going into your pocket, not theirs.
- The Growth Tax: They charge you "per seat" for every employee you add. They literally punish you for hiring more staff to grow your business.
The software doesn't work harder just because you sold a $50,000 item or hired a new clerk. So why pay more?
Use the calculator below to see exactly how much this "Triple Tax" is costing you.

Industry Comparison: Who Penalizes Your Growth?
Most legacy auction platforms operate on a "revenue share" model. The more you sell, the more they take. Selling Lane operates on a SaaS (Software as a Service) model: one flat fee, unlimited success.
