Effective odds at Sporttrade
| Odds | Effective | American | Break-even | Net profit on 100 |
|---|---|---|---|---|
| 1.50 | 1.490 | -204 | 67.11% | 49.00 |
| 1.91 | 1.892 | -112 | 52.86% | 89.18 |
| 2.00 | 1.980 | -102 | 50.51% | 98.00 |
| 2.50 | 2.470 | +147 | 40.49% | 147.00 |
| 3.00 | 2.960 | +196 | 33.78% | 196.00 |
| 5.00 | 4.920 | +392 | 20.33% | 392.00 |
| 10.00 | 9.820 | +882 | 10.18% | 882.00 |
Because commission comes off profit only, the effect grows with the odds. Short prices lose very little; long prices lose a meaningful slice. A bettor who mostly backs favourites therefore feels 2% commission far less than one who backs outsiders.
Lay bets
Laying at Sporttrade reverses the bet: you accept a backer's stake and risk a liability of stake × (odds − 1). Commission is charged on your profit when the outcome loses. Switch the calculator to "lay" to see liability, profit after commission and break-even for a lay at any price.
Comparing with a bookmaker
The honest comparison between an exchange price and a bookmaker price is after commission. Take the exchange price, apply Sporttrade'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.
Frequently asked questions
What does 2% commission do to my odds at Sporttrade?
On net winnings, commission takes 2% of the profit on a win and nothing on a loss. Even money becomes 1.980; the effect is larger at longer odds because the profit slice is larger.
What bookmaker price equals a Sporttrade price?
The break-even odds shown by the calculator: a bookmaker offering more than that beats Sporttrade after commission, one offering less does not.
How is a lay bet's liability calculated?
Liability = backer's stake × (odds − 1). If you lay 100 at 2.10, you risk 110 to win 100 minus commission.
Is the 2% figure current?
