Circa Sports charges no commission, so the table shows the quoted prices unchanged. Its margin lives inside the odds instead, which is why a sharp bookmaker's prices are often the reference line that exchange prices are compared against. Use the table to see what an exchange would have to quote, after its commission, to match a Circa Sports price, and the devig calculator to strip the built-in margin.
Comparing with a bookmaker
The honest comparison between an exchange price and a bookmaker price is after commission. Take the exchange price, apply Circa Sports's rate, and read off the effective odds; if the bookmaker offers more than that, the bookmaker is the better bet. The break-even column is the same comparison expressed as a win rate: a bookmaker price whose implied probability is below the exchange's break-even rate beats the exchange.
When the rate changes
Commission is not fixed. Exchanges vary it by country, discount activity-based tiers apply, and promotional rates come and go. The calculator's custom option lets you type any rate, and the table above shows how much a percentage point of commission is worth at each price: at even money one point costs about half a hundredth of a decimal point, at 10.00 it costs nearly a tenth.
