System bet calculator.
Add up to 6 selections and bet them as doubles, trebles, fourfolds and more. See combined odds, total stake, return and exactly how many must land to go into profit.
Selections (3)
Expected value uses the win % you set per selection and assumes the selections are independent. Leave a win % blank to use the odds-implied chance.
Mark matches as won, lost or void to test the system with the results you expect.
System
Pick which combination sizes to bet. Each line is staked separately.
What should you play?
- Best balance: All doubles. Expected ROI +1.5% with a 40% chance of turning a profit.
- Highest expected ROI: Accumulator at +2.3%, but it only lands 16% of the time.
- Most reliable: All singles returns a profit 58% of the time (ROI +0.7%).
Higher combinations multiply your edge, so they pay more when they land but win less often. Singles and low combinations win more often but grow slower.
| Structure | Bets | Exp. ROI | Hit chance |
|---|---|---|---|
| Accumulator | 1 | +2.3% | 16% |
| Full cover | 4 | +1.7% | 16% |
| All doublesRecommended | 3 | +1.5% | 40% |
| Full cover + singles | 7 | +1.3% | 40% |
| All singles | 3 | +0.7% | 58% |
Every figure here comes from the win % you entered per selection — not from the tipster's record. Leave it blank and it falls back to the odds-implied chance, which is the same as assuming no edge at all. Same stake per bet across structures.
How many must land?
- Profit becomes possible from 3 of 3 correct (best-case combination of results).
- Profit is guaranteed once 3 of 3 land, whichever they are.
Results differ by which selections win because odds differ. Ranges below show worst to best case for each number of winners.
| Winners | Return (worst → best) | Profit (worst → best) |
|---|---|---|
| 3 / 3 | €16.45 | +€12.45 |
| 2 / 3 | €2.97 → €3.78 | €-1.03 → €-0.22 |
| 1 / 3 | €0 | €-4 |
| 0 / 3 | €0 | €-4 |
| Combination | Bets | Return if all win |
|---|---|---|
| Doubles | 3 | €10.22 |
| Trebles | 1 | €6.24 |
System bets spread risk across combinations but cost more in total stake. More bets is not more edge. Save the picks you actually back and track real results.

Frequently asked
What is a system bet?
A system bet covers several combinations of your selections at once — for example all the doubles and trebles from four picks. You win something even if not every selection lands, but you stake more because each combination is a separate bet.
What are Trixie, Yankee, Lucky 15, Heinz and Lucky 63?
They are named full-cover systems. Trixie = 3 selections, all doubles + the treble (4 bets). Yankee = 4 selections (11 bets). Heinz = 6 selections (57 bets). Adding singles makes them Patent, Lucky 15, Lucky 31 and Lucky 63. The calculator names your setup automatically.
How many selections must win to make a profit?
It depends on the odds, not just the count. The calculator shows, for every number of winners, the worst and best profit — and the point where profit becomes possible and where it is guaranteed.
Does this store my data?
The calculator itself stores nothing — it runs in your browser. Signed in, you can also build the coupon from picks you have access to and save it to your private bet history. It saves as "planned", so it stays out of your ROI until you mark it as placed. Vault numbers are only ever your own.
