How to use the round robin calculator
- Enter your picks (up to eight) in any odds format. American odds such as
−110and+150work as typed. - Choose the round robin type: by 2s, 3s, 4s and so on, or all sizes.
- Enter the stake per parlay.
- Mark picks as Lost or Void / push to see how the parlays settle.
You see the number of parlays, your total risk, the total return and the profit.
Round robin sizes
The number of parlays depends on how many picks you have and the size you choose.
| Picks | By 2s | By 3s | By 4s | By 5s |
|---|---|---|---|---|
| 3 | 3 | 1 | ||
| 4 | 6 | 4 | 1 | |
| 5 | 10 | 10 | 5 | 1 |
| 6 | 15 | 20 | 15 | 6 |
Example: four picks by 3s
Four picks at −110, +120, −105 and +150, with $10 on each parlay. That is 4 parlays and $40 at risk.
- If all four picks win, the parlays return $387.56 (profit $347.56).
- If the +120 pick loses, only the parlay made of the other three survives. It returns $93.18, a profit of $53.18 on $40.
- Run the same picks by 2s and you get 6 parlays, $60 at risk and $273.76 back if everything wins.
When a round robin makes sense
- You like several picks but cannot stomach losing everything on one miss.
- You want a fixed number of parlays at fixed sizes, instead of choosing combinations by hand.
- Each pick is priced fairly. If your picks are weak, more parlays only lose faster.
For one parlay on every pick, use the parlay calculator. For British full-cover bets such as Yankees and Lucky 15s, see the bet calculator. Read what is a parlay and same game parlays for the risks.
