Free bet conversion calculator
Convert a free bet into guaranteed cash via lay matching
Convert a free bet into guaranteed real cash by laying it at a betting exchange.
What is free bet conversion?
Most free bets have a catch: you only keep the winnings, not the stake. A €50 free bet at 2.00 only pays you €50 (the €50 stake doesn't return). Matched bettors extract real cash by laying that same selection at a betting exchange — guaranteeing some net profit either way. Typical conversion rates are 70-80% depending on odds and exchange commission. Combine with Bet boost comparison to evaluate which promo offers convert best.
