Reduced Juice vs a Betting Rebate: Which Cuts Your Vig More?

Short answer: better prices usually beat a small rebate

Reduced juice lowers the cost of every single bet you place, win or lose. A rebate gives some of that cost back later, and only on the part of your action the terms cover. For a bettor who wins about half the time, moving from -110 to -105 cuts the expected yearly cost of vig roughly in half, while a 0.5% or 1% turnover rebate trims it by only a fifth or so.

The exception is a rebate paid on each losing bet at a meaningful rate, such as 5% of the stake back on every loser. That structure can be worth more than -105 pricing, but such offers are uncommon and usually come with caps, minimum odds or bonus-credit payouts. The rest of this article shows the math behind both models so you can price any offer yourself, or plug your own numbers into the cashback calculator.

How vig is built into a -110 line

Standard point-spread and totals markets are priced at -110 on both sides. You risk $110 to win $100, so a winning bet returns $210 and a losing bet costs $110. The break-even win rate is 110 divided by 210, or 52.38%, and two sides at 52.38% add up to 104.76% of implied probability. That extra 4.76% is the overround, the margin the book builds into the market.

The overround is not the same number as your expected loss per dollar. If you risk a flat $100 per bet at -110 and your picks are true coin flips, each win pays $90.91 and each loss costs $100. Your expected result is half of $90.91 minus half of $100, or about -$4.55 per bet, which is 4.55% of the amount you risk. Both figures describe the same price; the 4.55% is the one that matters for budgeting.

Converting any American price

• Negative odds (favorite or juiced line): implied probability = odds / (odds + 100). For -105 that is 105 / 205 = 51.22%.
• Positive odds (underdog): implied probability = 100 / (odds + 100). For +150 that is 100 / 250 = 40%.
• Overround: add the implied probabilities of every side of the market and subtract 100%.

Reduced juice: what -107 and -105 change

Reduced-juice pricing keeps the market structure but shrinks the margin. At -107 on both sides, break-even falls to 107 / 207 = 51.69%. At -105 it falls to 51.22%, a drop of about 1.16 percentage points from the standard -110 line. That sounds small, but it applies to every wager, so it compounds across a season.

Example. You risk $100 on a 50% proposition. At -105 a win pays 100 / 1.05 = $95.24. Expected value per bet = 0.5 x $95.24 - 0.5 x $100 = -$2.38. At -110 the same bet is worth -$4.55. Over 500 bets the difference is 500 x ($4.55 - $2.38), roughly $1,080 saved.

Reduced juice has two practical strengths. First, it is paid in the price itself, so there is nothing to claim, no expiry and no bonus credit to roll over. Second, it rewards you more when you win more: a lower break-even point helps a skilled bettor and an unlucky one in the same proportion per bet.

How betting rebates are structured

Rebates come in three common shapes, and the math differs sharply between them. Always read which base the percentage applies to before comparing it with a price improvement. The ways the base is calculated are covered in more detail on the sportsbook cashback page.

1. Turnover (handle) rebate. A fixed percentage of everything you wager, win or lose, for example 0.5% or 1%. It is predictable and pays regardless of results.
2. Rebate on losing bets. A percentage of the stake of each losing wager, for example 5%. It pays only on losers, so it is worth more to a bettor who loses more often.
3. Net-loss rebate. A percentage of your net loss over a period, for example 10% of the week's losses. If you finish the period ahead, it pays nothing at all.

Many rebates are credited as bonus funds rather than cash. A bonus credit that must be wagered or that returns only winnings is worth less than its face value, so a 1% rebate paid in restricted credit is not the same as 1% in withdrawable cash. The sibling article on lossback and bet insurance shows how to discount bonus bets to a cash figure.

Break-even win rates under each model

A rebate lowers your break-even point too, and the formula shows how much. Let w be the profit per $1 risked on a win (0.9091 at -110) and r the rebate rate. For a turnover rebate, expected value is p x w - (1 - p) + r, so break-even p = (1 - r) / (1 + w). For a rebate on losing stakes, expected value is p x w - (1 - p) x (1 - r), so break-even p = (1 - r) / (w + 1 - r).

Example. At -110 with a 1% turnover rebate: (1 - 0.01) / (1 + 0.9091) = 0.99 / 1.9091 = 51.86%. With a 0.5% turnover rebate: 0.995 / 1.9091 = 52.12%. With 5% back on every losing stake: 0.95 / (0.9091 + 0.95) = 0.95 / 1.8591 = 51.10%.

Compare those numbers with -107 (51.69%) and -105 (51.22%). A 1% turnover rebate on -110 lines is weaker than -107 pricing, and only the 5%-per-loser structure beats -105. A net-loss rebate has no fixed break-even improvement because its value depends on whether the whole period ends in the red.

Yearly cost of vig on 500 bets of $100

The table below prices one season for a bettor who risks a flat $100 on each of 500 two-way bets, for $50,000 of total stakes. Two win rates are shown: 50%, a bettor with no edge, and 52%, a bettor who picks slightly better than a coin flip. Rebates are assumed to be paid in withdrawable cash and to apply to every bet. All figures are expected values computed by rewinly.com editors, not guarantees.

How the rows are calculated. At -110 and 50% wins: 250 wins x $90.91 - 250 losses x $100 = -$2,273. A 1% turnover rebate adds 1% x $50,000 = $500. Five percent back on losers adds 250 x $5 = $1,250. A 10% net-loss rebate returns 10% of the expected $2,273 loss, about $227. At 52% wins the -110 baseline is 260 x $90.91 - 240 x $100 = -$364, so the net-loss rebate returns only about $36.

When a rebate is worth more than better prices

The table points to a few clear rules. A rebate wins the comparison only when its rate is high relative to the vig it offsets, when it is paid in cash, and when it covers all of your action. In practice that means checking the terms against the break-even formula rather than the headline percentage.

• Per-loser rebates of several percent can beat -105, because they refund part of the stake you actually lost on each losing ticket.
• Turnover rebates of 1% or less rarely beat genuine reduced juice; they sit between -110 and -107 in value.
• Net-loss rebates are the weakest for a winning bettor and pay most to the bettor who is losing, which is why they deserve the extra caution described in the loss-chasing trap.
• Bonus-credit payouts must be discounted, often heavily, before you compare them with a cash price improvement.
• Parlays and props often carry a wider margin than -110 sides, so a flat rebate on them offsets a smaller share of the real cost.

The two are not mutually exclusive. If a rebate applies on top of reduced-juice lines, the savings stack, and the break-even formula above still works: replace w with the profit per dollar at the reduced price.

Practical checklist before you compare offers

Treat both reduced juice and rebates as ways to lower a cost, not as a reason to bet more. Every row in the table above is still negative for a bettor with no edge; a smaller loss is still a loss. Decide your stake size and budget first, then pick the pricing that costs least for that plan.

1. Write down the price you would actually get on your usual markets, not the best price shown in an advertisement.
2. Identify the rebate base: turnover, losing stakes or net loss, and the period it is counted over.
3. Check whether the payout is cash or bonus credit, and any cap, minimum odds or excluded markets.
4. Run your expected handle and a realistic win rate through the formulas, or through the calculator, and compare the yearly result.
5. Set a deposit or loss limit in your account before the cycle starts, so the comparison never becomes a reason to increase volume.
