How is this result calculated?The tool converts every format to Decimal first, then uses the same payout math for singles, parlays/accas and system bets.
Implied probability = 1 ÷ Decimal odds
Combined priced probability = multiply each leg's implied probability (independent-leg assumption)
Profit = stake × (Decimal − 1)
Potential win return = profit ÷ total outlay
How system bets are handled
The system tab creates every 2/N, 3/N or 4/N round-robin combo with the same stake per combo. The headline card shows the all-legs-win case; the ladder shows what different numbers of winning legs can return.
Quick example
$100 at Decimal 2.50 returns $250 total, with $150 profit and a 150% potential win return. A three-leg parlay with each leg priced at 50% has a 12.5% combined priced probability if the legs are independent.
Entered price implies 50% or more · Entered price implies 30% to 49.99% · Entered price implies below 30%
HOW IT WORKS
Pick a slip. Add odds. Check the payout.
Use one odds format for the whole slip by default. Add your stake and lines, then read profit, total payout and the priced probability before you place the bet.
02
Type stake and odds
Choose the odds format once, then enter every line in that format. If a slip really mixes formats, open the advanced per-leg setting.
03
Read the payout before any illustration
Start with profit, total payout and potential win return. The optional variance illustration appears only for a valid Single bet and uses an explicit fair-line assumption.

PRICED CHANCE BANDS
What the priced-chance bands mean
The bands use 1 ÷ Decimal odds only. They do not know your edge, bankroll, market margin or the true chance of the outcome.
50%+
50%+ — shorter entered price
The entered price implies at least 50%. That normally means a shorter price and lower potential profit, not a safer or better bet.
30–49.99%
30–49.99% — middle price range
The entered price implies between 30% and 49.99%. Use it as a price-reading shortcut only; value still depends on an independent probability estimate.
Below 30%
Below 30% — longer entered price
The entered price implies below 30%. Parlays often reach this band because leg probabilities multiply, but this calculator does not recommend a stake.

This is a fair-line variance illustration, not an edge model. One entered price cannot reveal the full market margin, correlations or the outcome's true probability.
This is a calculator, not betting advice. It uses the odds you enter and standard payout math; final settlement always depends on the sportsbook's confirmed slip, market rules and any void, push, cash-out or bonus-bet terms.
FAQ
Common questions about bet calculation
The questions bettors usually check before placing a slip: payout math, void legs, accas, system stakes, same-game parlays and odds formats.
How do I calculate profit and total return on a single bet?
Profit = (decimal odds − 1) × stake. Total payout = decimal odds × stake. So a $100 single at 2.50 pays $250 back: $150 profit plus the original $100 stake.
How are parlay, accumulator or acca odds multiplied?
Every leg is converted to Decimal first, then multiplied. Example: 2.00 × 1.91 × 2.10 = 8.022. A normal parlay/acca needs every leg to win. The displayed combined priced probability multiplies each leg's implied probability and assumes the legs are independent.
What happens if one parlay leg is void, pushed or cancelled?
In most sportsbooks, a void, push or cancelled leg is treated as Decimal 1.00, so it neither wins nor loses and the parlay is recalculated using the remaining valid legs. Final settlement still depends on the bookmaker's own rules.
What do 2/N, 3/N and 4/N system bets mean?
A system bet, also called a round robin in some markets, splits your picks into smaller combos. 2/N creates every double, 3/N every treble and 4/N every four-fold. You may still get a return without every leg winning.
How is total stake calculated for a system bet?
Total stake = stake per combination × number of combinations. For example, five selections in a 2/N system create 10 doubles. If you stake $10 per combo, your total outlay is $100.
Why might the calculator differ from my sportsbook payout?
Common reasons are odds movement, rounding, void/push legs, cash-out, free bets, bonus stakes or local settlement rules. The calculator uses the odds you type in; the confirmed sportsbook slip decides the final payout.
Can I use this for same-game parlays?
Use it only as a rough payout check. Same-game parlay legs are often correlated, so sportsbooks reprice them instead of simply multiplying each leg like a normal accumulator. The final in-app SGP price is the number that matters.
How do I enter Hong Kong, Malay or Indonesian odds?
Choose the odds format shown on your betting screen, then type the price exactly as displayed. The calculator converts Hong Kong, Malay and Indonesian odds to Decimal first, then calculates single, parlay and system returns from that Decimal value.
