Bonus Bet Value Calculator
Estimate how much cash value you could retain from a stake-not-returned (SNR) free bet you’ve already been issued, from the bonus amount, your back odds and any lay commission. Educational only — no offers shown.
This is an estimate of the value you could retain from a free bet you have already been issued. The real figure depends on getting a matching lay price at the time, and higher back odds generally retain more of a stake-not-returned bonus. HaterPicks doesn’t offer or promote bonuses.
What is a bonus bet worth?
A stake-not-returned free bet pays only the profit, not the stake, so it’s never worth its full face value in cash. This tool estimates the retained value if you were to place the free bet and lay it off. It exists to help you understand the maths of a bonus you already hold — HaterPicks does not offer or advertise bonuses.
The formula
conversion % = value ÷ Bn × 100
where Bn = bonus amount, O = decimal back odds, and c = lay commission percentage (0 if you’re not hedging on an exchange).
Worked example
A $50 SNR free bet placed at decimal odds of 4.00, with no lay commission, estimates to 50 × (3 ÷ 4) × 1 = $37.50 — a 75% conversion. The same bonus at 2.00 would estimate to just 50 × (1 ÷ 2) = $25 (50%), which is why longer odds retain more of a stake-not-returned bonus.
When to use it
Use it to understand what a free bet you already hold is roughly worth in cash before deciding how to use it. Remember it’s an estimate — the real outcome depends on being able to lay the bet at a matching price when you act, and prices move. It is not betting advice.

What is a stake-not-returned (SNR) bonus bet?
A stake-not-returned free bet pays only the winnings, not the stake itself. If you place a $50 SNR bonus at decimal odds of 4.00 and it wins, you receive the $150 profit — the $50 “stake” is not returned. That’s why a free bet is worth less than its face value in cash.
How do you estimate the value of a bonus bet?
A common honest model estimates retained value as Bonus × (O − 1) ÷ O, optionally reduced by any lay commission: value ≈ Bn × (O − 1)/O × (1 − c/100). Dividing by the bonus amount gives the conversion percentage. It assumes you can lay the bet off at a matching price.
Why do higher odds convert a free bet better?
Because the stake isn’t returned, the (O − 1)/O factor grows towards 1 as odds rise. At short odds you keep a small fraction of the face value; at longer odds you keep more — which is why free-bet conversion strategies typically use higher back odds.
Is this a guaranteed figure?
No. It’s an estimate that depends on getting a matching lay price at the moment you hedge, which is not always available. HaterPicks is a research and analytics product — it does not offer, advertise or promote bonuses, and this is not betting advice.
