Quick Answer

TL;DR summary

For SNR (Stake Not Returned) free bets, use: Lay Stake = (Back Odds - 1) × Free Bet Value / (Lay Odds - Commission). A $50 SNR free bet at 5.00 odds, laid at 5.20 with 5% commission: Lay Stake = (5-1) × $50 / (5.20-0.05) = $38.83. Guaranteed profit: ~$38.35 (76.7% retention). Higher back odds = higher profit.

Frequently Asked Questions

Common questions about SNR free bets

What is an SNR free bet?

SNR stands for Stake Not Returned. With an SNR free bet, if your bet wins, you only receive the winnings (profit), not the original stake. For example, a $50 SNR bet at 4.00 odds that wins pays $150 profit, not $200 total. This is the most common type of free bet offered by bookmakers.

Why is the SNR formula different from normal bets?

Because SNR free bets don't return the stake, you only need to lay the potential winnings (Back Odds - 1) × Stake, not the full return. This means a smaller lay stake and liability, but the same profit retention concept applies.

What odds should I use for SNR free bets?

Use odds of 4.0 or higher for best results. Higher odds mean a larger portion of the return is profit (not stake), which you can't lose anyway with an SNR bet. At 5.0 odds, 80% of the return is profit. At 10.0 odds, 90% is profit.

How much profit can I expect from an SNR free bet?

Typical retention is 70-85% of the free bet value. A $50 free bet usually returns $35-42 in guaranteed profit. The exact amount depends on odds available and exchange commission. Higher odds and lower commission increase profit.

Should I let the free bet ride or lay it?

Always lay it. Laying guarantees your profit regardless of outcome. Letting it ride means gambling - you might win more, but you could also win nothing. Matched betting is about guaranteed returns, not gambling.
