Even money (evens)
Even money is a price at which your profit on a winning bet equals your stake, so a €10 bet returns €20 in total. Irish bookmakers show it as evens, EVS or 1/1 in fractional odds, and as 2.00 in decimal. Before any margin is taken, that price implies a 50% chance. On a casino table the same phrase describes a 1:1 payout, which is not the same thing as a fair coin toss.
How the even-money sum works
The arithmetic is short: implied probability is 1 divided by the decimal price, so 1 ÷ 2.00 gives 50%. The fractional version reads the same way, with 1/1 meaning one unit of profit for each unit staked.
Prices either side of evens tell you which way the bookmaker leans. A horse at 4/5 (1.80) implies about 55.6%, while 6/5 (2.20) implies about 45.5%, so anything shorter than evens is odds-on and anything longer is odds-against.
Free bets change the return, and that is where readers most often get caught out.
A €10 free bet struck at evens pays €10 in winnings only, because the free stake is not returned, whereas the same bet with your own cash gives back €20.
Is an even-money price really fifty-fifty?
Rarely, and the margin explains why. In a two-way market where a bookmaker prices both sides at 10/11 (about 1.91), each side implies roughly 52.4%, so the book adds up to about 104.8% rather than 100%.
Roulette shows the same gap in a different form. On a single-zero wheel, red covers 18 of 37 pockets, giving a 48.65% chance against a 1:1 payout, and the zero is where the 2.7% house edge comes from.
Even-money price compared with a true coin toss
The table sets an even-money bet, as you meet it at a bookmaker or casino, against a genuinely fair 50/50 outcome.
Even-money bet | True 50/50 chance |
|---|---|
| Profit equals stake on a win | Profit equals stake on a win |
| Win chance usually just under 50% | Win chance exactly 50% |
| Red on a European wheel: 48.65% | No zero pocket to lose on |
| Margin or house edge built in | No margin taken |
| Shown as EVS, 1/1 or 2.00 | No price printed anywhere |
| La Partage halves the roulette edge to 1.35% | No rule needed to correct it |
Terms often confused with even money
Even money is not the same as a draw-no-bet or a void bet, where your stake comes back without profit.
It is also separate from “evens” used loosely to mean a close contest, since a price only reflects the bookmaker’s view plus its margin. On French roulette tables the La Partage rule returns half of an even-money stake when zero lands, though which tables carry it varies between operators.
