This commercial auction financing calculator estimates the two numbers that decide the deal after you win a commercial property at auction: your total cash to close and your monthly carrying cost on a bridge loan. Your close date is fixed, your deposit is non-refundable, and there is no financing contingency, so the math needs to be right before you bid. Enter your own figures below. Everything updates as you type.

Bidding on a specific deal? Let's talk before the gavel drops. We know which of 700+ bridge lenders actually fit an auction close, so you can plan your financing with a clear head instead of a guess.
How to read this commercial auction financing calculator
Cash due at close is your equity plus loan fees and closing costs, minus the earnest deposit you already wired. It is the wire you send to actually take title.
Why interest-only? Commercial bridge loans are almost always interest-only, so your monthly cost is the loan balance times your rate, divided by twelve. You repay the principal when you sell or refinance into permanent debt.
What the buyer's premium does. Most auction platforms add a premium on top of your winning bid, so your real purchase price and your real loan are both based on bid plus premium, not the bid alone. This tool builds that in.
