How to use the bet calculator
- Enter the odds for one leg for a single bet, or two to six legs for a parlay. Any format works:
1.85,−118,17/20. - Leave the boxes you don't need blank.
- Enter your stake.
You'll see the bet type, the total odds (decimal and American), the total return and your net profit — plus the implied chance of the whole bet landing.
Example: a two-leg parlay
You back a CS2 favourite at 1.85 and a League of Legends team at 2.10, with $25:
| Value | |
|---|---|
| Total odds | 1.85 × 2.10 = 3.89 (+289) |
| Total return | $97.13 |
| Net profit | $72.13 |
| Implied chance | 25.7% |
The same $25 on the 1.85 leg alone returns $46.25 — a $21.25 profit at a 54% implied chance.
How the margin stacks up in a parlay
If every leg is a fair coin flip priced at 1.90 (about 5% margin on each side), here's what happens as you add legs:
| Legs | Total odds | Fair odds | Payout vs fair |
|---|---|---|---|
| 1 | 1.90 | 2.00 | 95% |
| 2 | 3.61 | 4.00 | 90% |
| 3 | 6.86 | 8.00 | 86% |
| 4 | 13.03 | 16.00 | 81% |
| 6 | 47.05 | 64.00 | 74% |
Parlays are a fine way to have fun with small stakes on a big weekend of matches — just know the price of that fun grows with every leg.
Esports rules to check before you bet
- Forfeits and walkovers: a team pulling out can void the leg or, at some books, settle it as a loss.
- Stand-ins and roster changes: most bets still stand if a team plays with a substitute.
- Map count: "match winner" bets settle on the series, not on one map. See map handicaps and series betting.
A three-leg parlay across different games
Parlays often mix titles on a busy day. Say you back a CS2 map winner at 1.70, a League of Legends team at 1.55 and a Valorant team at 2.05, with $25:
| Value | |
|---|---|
| Total odds | 1.70 × 1.55 × 2.05 = 5.40 (+440) |
| Total return | $135.04 |
| Net profit | $110.04 |
| Implied chance of all three | 18.5% |
Each leg looks comfortable on its own, but all three have to win, and the combined chance is under one in five. If one of the matches is a Bo1, treat that leg with extra care: single maps are the most random bets in esports.
Games also differ in how often upsets happen and how much a roster change matters, so a parlay across titles carries risks from each of them. Keep the stake small and the legs few.
