-110 break even: the win rate a capper actually needs
By Karel Moreau, editor of sportspicksdiscord ·
At standard -110 odds you need to win 52.38% of bets just to break even. You risk $110 to win $100, so each loss costs more than each win pays; the gap is the sportsbook's vig. That single number is the most useful tool you have for judging any picks service — and once you add the price of the subscription, the bar gets much higher than most buyers realise.
Where 52.38% comes from
At -110, a winning $110 bet returns $100 profit and a losing one costs $110. To break even, wins × $100 must equal losses × $110. Solve it and the winning share is 110 / (110 + 100) = 52.38%. The general formula for any negative American price is |odds| / (|odds| + 100); for positive prices it is 100 / (odds + 100).
Break-even win rate at common odds
| American odds | Decimal | Break-even win rate |
|---|---|---|
| -200 | 1.500 | 66.67% |
| -150 | 1.667 | 60.00% |
| -120 | 1.833 | 54.55% |
| -115 | 1.870 | 53.49% |
| -110 | 1.909 | 52.38% |
| -105 | 1.952 | 51.22% |
| +100 | 2.000 | 50.00% |
| +120 | 2.200 | 45.45% |
| +150 | 2.500 | 40.00% |
| +200 | 3.000 | 33.33% |
What a win rate is actually worth
Every point above 52.38% is profit; every point below is loss. Expected profit per one-unit bet at -110:
| Win rate | Profit per bet | Per 100 bets |
|---|---|---|
| 50% | -0.045 u | -4.5 u |
| 52.38% | -0.000 u | -0.0 u |
| 53% | +0.012 u | +1.2 u |
| 55% | +0.050 u | +5.0 u |
| 57% | +0.088 u | +8.8 u |
| 60% | +0.145 u | +14.5 u |
Read the 55% row carefully. A capper hitting 55% at -110 — which would put them among the better ones — makes +0.050 units per pick. Five hundredths of a unit. Real edge in sports betting is thin, which is why any service advertising 70%+ win rates deserves a hard look at how it is counting.
Now add the subscription
The 53 picks communities this site tracks cost a median of $64 per 30 days once weekly and three-day passes are normalised to a month. Say you bet $20 a unit. Just to cover the subscription you need 3.2 units of profit a month — before you make a cent.
| Capper hits 55% at -110 | 64 picks a month just to pay for the sub |
|---|---|
| Capper hits 53% at -110 | 272 picks a month just to pay for the sub |
| Capper hits 52.38% | Never. You lose exactly the subscription fee. |
That is the arithmetic most pick sellers do not show you. At small stakes, a paid picks service has to be very good just to cost nothing. The subscription only makes sense relative to your unit size — the bigger your units, the smaller the drag.
Why a short record proves almost nothing
Results at -110 are close to coin flips, so they are noisy. Over 100 picks, a true 55% capper will land anywhere from roughly 45% to 65% about 95% of the time. To tell a genuine 55% capper from a break-even one with that confidence you need around 1,457 graded picks. A "hot month" of 60 picks is noise.

Using this to judge a picks service
- Ask for the full record in units at the actual odds. A 58% record at -150 is worse than a 54% record at -110 (break-even at -150 is 60%).
- Divide the claimed profit by the number of picks. Anything much above 0.1 units per pick over a long record should be questioned.
- Count the picks. Under a few hundred, the record tells you little either way.
- Price the subscription in units. Monthly cost ÷ your unit size = the profit the capper has to generate before you are ahead.
Frequently asked questions
What is the break-even percentage at -110?
52.38%. You risk $110 to win $100, so you need to win 110 of every 210 bets to break even.
How do you calculate break-even win rate?
For negative odds: |odds| ÷ (|odds| + 100). For positive odds: 100 ÷ (odds + 100). At -110 that is 110 ÷ 210 = 52.38%.
Is a 55% win rate good in sports betting?
At -110 it is very good, but it is only worth about +0.05 units per bet. A subscription service has to clear its own price on top of that.
How many picks do you need to judge a capper?
Around 1,457 graded picks to separate a true 55% capper from a break-even one with roughly 95% confidence. Short records are mostly noise.
