Double Chance Calculator: Fair Odds & All Markets (2026)
Enter the home, draw and away odds and this tool builds all three double chance markets at once, strips out the bookmaker's margin to show the fair price, and works out your return. No rival calculator derives the fair odds from 1X2.
Double chance calculator
1X2 odds
Enter the standard home, draw and away decimal odds.
Leave offered odds blank to use the fair price. Add the bookmaker's actual double chance odds for an exact return and a fair-price comparison.
Result
Return shown at the fair no-vig price. A real bookmaker will pay a little less.
This is the margin baked into the three 1X2 prices. The fair odds above remove it, so the real bookmaker double chance price will be shorter than fair.
What 1X, 12 and X2 cover
Each double chance market covers two of the three match outcomes. Here is exactly when each one wins and loses.
| Market | Covers | Wins if | Loses only if |
|---|---|---|---|
| 1X | Home win or draw | Home wins or it is a draw | The away team wins |
| 12 | Home win or away win | Either team wins | It is a draw |
| X2 | Draw or away win | Away wins or it is a draw | The home team wins |
The double chance formulas
Every number here comes from the three 1X2 prices. Nothing is guessed.
Implied chance
p = 1 / odds
Turn each 1X2 price into a probability. Home 2.0 implies a 50% chance.
Combine two outcomes
double chance chance = pA + pB
A double chance covers two outcomes, so add their probabilities. 1X is home plus draw.
Fair no-vig odds
fair = (pH + pD + pA) / (pA + pB)
Normalise by the 1X2 total to strip the margin, then invert for the fair decimal price.
Return
return = stake x odds
Your return is stake times the price you actually get. Profit is the return minus the stake.
Double chance betting, priced properly
A double chance bet trades a smaller payout for a bigger safety net by covering two of the three match outcomes. As of 2026 this ToolsGambling calculator does what the settle-only tools do not: it builds all three markets from the raw 1X2 odds and shows you the fair price, so you can see exactly how much margin the bookmaker has folded into the double chance market.
What is a double chance bet?
A double chance bet covers two of the three possible results in a football match on a single ticket. Instead of picking just the home win, you back home or draw, so you win if either lands. The trade-off is a shorter price, because you are far more likely to win.
There are three markets. 1X backs the home win or the draw. X2 backs the draw or the away win. 12 backs either team to win, with only the draw losing. You are buying insurance against one outcome, and the odds reflect how likely that cover is.
Because two outcomes are covered, double chance prices are usually short, often between 1.20 and 1.50 for a favourite. That is why the fair price and the margin matter so much: a small difference in odds is a big difference in value at these levels.
For a long time I treated double chance as a beginner's crutch, until I started comparing the offered price to the fair price. On some matches the double chance market is padded far more than the 1X2, and once you can see that, you either bet the two singles instead or walk away.
The three double chance markets
Every double chance bet is one of these three, and the calculator prices all of them at once from your 1X2 odds.
1X: home win or draw
The most popular double chance. It wins if the home team wins or draws, and only loses if the away side wins. It is the go-to cover for a home favourite you are not fully confident in.
X2: draw or away win
The mirror image, backing the away team or the draw. It loses only if the home side wins. Useful when you fancy an underdog to at least avoid defeat.
12: home or away win
This one covers both teams to win and loses only on a draw. It is the pick when you expect a decisive result but cannot call which way, common in cup ties and derbies.
How do you calculate double chance odds?
Four steps, and the tool runs them the moment you type. Doing it once by hand shows you where the margin hides.
- 01
Turn odds into probabilities
Divide one by each 1X2 price. Home 2.0 is 50%, draw 3.33 is 30%, away 4.0 is 25%.
- 02
Add the two you cover
For 1X add the home and draw probabilities. In this example 50% plus 30% is an 80% raw chance.
- 03
Strip the margin
The three 1X2 probabilities sum to more than 100% because of the vig. Divide the combined chance by that total to get the fair no-vig probability.
- 04
Invert for the price
One divided by the fair probability is the fair decimal price. Compare it to what the bookmaker actually offers on double chance.
Why the fair price matters
Bookmakers do not just pass the 1X2 margin into double chance. They often add more, because casual bettors treat double chance as a safe bet and do not shop the price. That is exactly where value leaks away.
When you enter the offered double chance odds, the calculator compares them to the fair price. If the gap is wide, backing the two outcomes separately, or dutching them, can return more than the double chance ticket for the same cover.
When is double chance worth it?
Double chance lowers variance, not the house edge. It suits some situations and quietly wastes value in others.
Cup ties and knockouts
When a result matters more than style, 12 to cover both winners is a clean way to back a decisive game without calling the side.
Shaky favourites
1X on a home favourite you half-trust turns a nervy 90 minutes into a bet that survives a draw. You pay for that comfort in a shorter price.
When the price is padded
If the offered double chance odds sit well below the fair price, skip it. Back the two outcomes separately or move on. The margin comparison above flags this.
