Calculate how to maximize the value of free bets and bonuses from bookmakers

Free bets are promotional offers from bookmakers that allow you to place a bet without risking your own money. There are two main types:

Stake Not Returned (SNR): If your bet wins, you receive only the profit, not the free bet stake.
Stake Returned (SR): If your bet wins, you receive both the profit and the free bet stake.

This calculator helps you determine the optimal strategy to extract maximum value from free bets using matched betting techniques.

Recommendation:

Look for high odds (typically 3.0+) to maximize the conversion rate for SNR free bets.
Try to find close matches between back and lay odds to minimize the qualifying loss.
Consider using betting exchanges with lower commission rates to increase your profit.
Always check the terms and conditions of free bets for minimum odds requirements and other restrictions.
For SR free bets, lower odds can sometimes be more profitable than higher odds.
