How to Read Betting Odds: Decimal, Implied Probability
October 6, 2026
Read decimal odds, calculate implied probability, understand overround, convert fractional and American odds and read an exchange price ladder.
The two coloured columns on every Tigerexch market are the whole exchange in miniature. Blue is where you back, pink is where you lay, and almost every mistake new players make comes from not knowing exactly what each click commits them to. This guide walks through the maths with real rupee figures — profit, liability, commission and trading out — so that before you place a single bet you know the best case, the worst case and everything in between.

A traditional bookmaker sets a price and you can only bet that something will happen. An exchange such as Tiger Exchange works differently: it is a marketplace where players bet against each other, and the platform simply matches the two sides and takes a small commission from winnings. That creates two kinds of bet.
When you lay, you are effectively taking the role a bookmaker normally plays: you accept somebody else's back bet. That is why lay betting has a "liability" — the amount you must pay out to the backer if the outcome does happen. Getting comfortable with that single idea is the key to everything else on this page.
Open any match-odds market after your Tigerexch login and each selection shows a row of prices. The blue boxes are the best prices currently available to back; the pink boxes are the best prices available to lay. Under each price is the amount of money waiting to be matched at that price.
The back price is always slightly lower than the lay price. If India show 1.90 in blue and 1.92 in pink, the gap between them is called the spread. A tight spread usually means a busy, liquid market — an international fixture, for example — while a wide spread suggests few players are active and prices can jump. Before clicking, glance at the amounts under the prices: if only ₹500 sits at the best price and you want to stake ₹5,000, part of your bet may be matched at a worse price or stay unmatched.
All prices on Tigerexch are shown in decimal odds. Decimal odds include your stake, so a price of 2.50 means every ₹1 staked returns ₹2.50 in total if it wins — ₹1 of stake back plus ₹1.50 of profit. If you are more used to the Indian "rate" style, a rate of 40 paise corresponds to decimal odds of 1.40. Our separate guide on how to read betting odds goes deeper into conversions.
The formula for a back bet is simple and worth memorising:
Your maximum loss on a back bet is always the stake, no matter how high the odds. That is what makes backing the natural starting point for new players.
| Example | Stake | Back odds | Profit if it wins | Loss if it loses |
|---|---|---|---|---|
| Favourite to win | ₹1,000 | 1.50 | ₹500 | ₹1,000 |
| Even match | ₹1,000 | 2.00 | ₹1,000 | ₹1,000 |
| Slight underdog | ₹1,000 | 2.50 | ₹1,500 | ₹1,000 |
| Clear underdog | ₹500 | 4.00 | ₹1,500 | ₹500 |
Look at the last two rows: ₹1,000 at 2.50 and ₹500 at 4.00 both produce ₹1,500 profit, but the second risks only half as much. It also wins far less often, because 4.00 implies roughly a 25% chance while 2.50 implies roughly 40%. Odds are a statement about probability, not just about payout — a point we come back to in our cricket betting strategy guide.
When you lay, you choose a stake — the amount you win if the outcome does not happen — and the exchange works out your liability:
Lay ₹1,000 on a team at 2.50 and you win ₹1,000 if they lose. If they win, you pay ₹1,000 × 1.50 = ₹1,500. The ₹1,500 is blocked from your available balance the moment the bet is matched, which is why your balance seems to "drop" more than the stake you typed.
Now lay the same ₹1,000 on a strong favourite at 1.40. Liability is only ₹1,000 × 0.40 = ₹400. Lay a big underdog at 6.00 and the liability becomes ₹5,000 to win ₹1,000. The higher the odds, the more you put at risk to win the same amount — the opposite of backing.

| ₹1,000 bet at odds | Back: win | Back: lose | Lay: win (selection loses) | Lay: lose (selection wins) |
|---|---|---|---|---|
| 1.40 | +₹400 | −₹1,000 | +₹1,000 | −₹400 |
| 2.00 | +₹1,000 | −₹1,000 | +₹1,000 | −₹1,000 |
| 3.00 | +₹2,000 | −₹1,000 | +₹1,000 | −₹2,000 |
| 6.00 | +₹5,000 | −₹1,000 | +₹1,000 | −₹5,000 |
The table shows the mirror image clearly. Backing at long odds risks little to win a lot; laying at long odds risks a lot to win a little. Neither is "better" — they are two sides of the same trade, and the price decides who is getting value. Figures are before commission.
The exchange earns by charging a percentage of your net winnings on a market. You pay nothing on losing bets, and the commission is calculated after all your bets on that market are settled together. The applicable rate is shown in the market rules on your panel; we use 2% below purely for illustration.
Because commission is on net market profit, a trader who backs and lays repeatedly on one market only pays on the final result. That is fairer than paying on each winning slip, and it matters when the margins are small.
Many Indian players learned cricket betting through the lagai-khai vocabulary long before exchanges. Lagai means putting money on the favourite — the equivalent of backing. Khai means taking the bet against the favourite — the equivalent of laying. When someone says "India 40-42", they mean you can lagai India at 40 paise (decimal 1.40) or khai at 42 paise (decimal 1.42).
The maths is identical. Lagai ₹1,000 at 40 paise wins ₹400; khai ₹1,000 at 42 paise risks ₹420 to win ₹1,000. The exchange simply shows these as decimals in blue and pink columns. Our lagai-khai glossary, linked below, covers the rest of the slang.
Because you can both back and lay on the same market, you can open a position at one price and close it at another — exactly like buying and selling a share. This is called trading.
Before the toss you back Team A ₹1,000 at 3.00. They win the toss and a few early wickets fall in their favour, and the price shortens to 2.20. You now lay Team A at 2.20 to lock in a result whatever happens next.
To make the profit equal on both outcomes, the lay stake is back stake × back odds ÷ lay odds = ₹1,000 × 3.00 ÷ 2.20 ≈ ₹1,364.
Commission at 2% would then apply to the ₹364 net. Alternatively, you could lay just ₹1,000 at 2.20: you would then make ₹800 if Team A win (₹2,000 − ₹1,200) and break even if they lose — a "free bet" on your original selection. Many players use the cash-out button for this, which does the sum for you; see our guide on cash out and hedging.
Prices move both ways. If Team A drift from 3.00 to 4.50, laying now locks in a loss: lay stake ₹1,000 × 3.00 ÷ 4.50 ≈ ₹667, giving about −₹333 on either outcome. Taking a smaller, known loss can be sensible; hoping a drifting price comes back is how small losses become large ones.
Trading also works in reverse. Lay a team at 1.60 for ₹1,000 (liability ₹600). If they lose early wickets and drift to 2.40, back them to close: back stake = ₹1,000 × 1.60 ÷ 2.40 ≈ ₹667. If they win: −₹600 + ₹667 × 1.40 ≈ +₹333. If they lose: +₹1,000 − ₹667 = +₹333. Same principle, opposite direction: lay high-confidence prices you think are too short, back them later at a longer price.
The risk is the mirror image too. If the favourite strengthens from 1.60 to 1.20, closing your lay costs you, and if you do nothing, your full ₹600 liability is exposed. Always know your liability before you lay.

The bet slip opens with the price pre-filled. You can type a different price; if it is not available yet, the bet waits unmatched.
For a back bet the slip shows potential profit; for a lay it shows liability. Read that number — it is your real risk.
The market view shows green and red figures next to each team telling you what happens to your balance for every result.
Matched bets are live. Unmatched bets can be cancelled or edited until someone takes them. In-play markets add a short bet delay before acceptance.

Laying is a tool, not a strategy in itself. It makes sense when you believe a price is too short — the market is overrating a favourite — and the liability fits comfortably inside your bankroll. It makes sense for closing a back bet to lock in a result. And it is useful for opposing a single selection in a multi-runner market, such as laying one player in a "top batter" market rather than trying to pick the winner.
It does not make sense when the liability is large relative to your balance, when you are laying to chase a loss, or when you are laying in a market you do not understand. Set a maximum liability per bet as part of your bankroll plan — many disciplined players cap it at a small, fixed percentage of their balance. If betting ever stops feeling like entertainment, our responsible gambling page explains the limits and breaks you can set.
Exchange betting is offshore in model and Indian law varies by state; you are responsible for checking the rules where you live. Nothing here is a promise of profit — the examples show how the maths works, not what will happen.
Backing is betting that an outcome will happen; laying is betting that it will not. When you lay, you take the other side of someone else's back bet, so you win their stake if the outcome fails and pay their profit if it succeeds.
Profit = stake × (odds − 1). A ₹1,000 back at 2.50 returns ₹1,500 profit if it wins. If it loses, you lose the ₹1,000 stake and nothing more.
Liability is what you must pay if the selection you laid wins: stake × (odds − 1). Laying ₹1,000 at 2.50 has a liability of ₹1,500, which is blocked from your balance until the market settles.
Because the exchange holds your full liability, not your stake. A ₹1,000 lay at 4.00 blocks ₹3,000. It is released or paid out when the market settles.
Commission is a percentage of your net winnings on a market, calculated once the whole market settles. Losing bets pay nothing. The current rate is shown in the market rules on your panel.
Yes. Backing at a higher price and laying at a lower price (or the reverse) is called trading and can lock in a result before the match ends. If the price moves against you, closing locks in a loss instead.
At high odds, yes. Laying a 6.00 selection risks ₹5,000 to win ₹1,000. At short odds, such as 1.40, the liability is smaller than the stake. Always read the liability on the slip.
Lagai is backing the favourite and khai is laying it. A rate of 40 paise corresponds to decimal odds of 1.40. The exchange shows the same thing as blue and pink decimal prices.
Back का मतलब है कि आप मानते हैं कि result होगा, और Lay का मतलब है कि result नहीं होगा। Lay करते समय liability = stake × (odds − 1) होती है, इसलिए bet slip पर liability ज़रूर देखें।
