> **Short answer:** Betting odds dey tell you two things: how much you go collect if you win, and how likely di bookmaker reason say di result be. With decimal odds, your return na stake × odds. Low odds mean small return, and result wey dey more likely.

## Odds example: Gor Mahia vs AFC Leopards

See simple 1X2 market. "1X2" mean home win (1), draw (X) or away win (2).

| Result | Odds (example odds) | Wetin you go collect for KSh 100 | Profit for KSh 100 |
|---|---|---|---|
| Gor Mahia win (1) | 2.10 | KSh 210.00 | KSh 110.00 |
| Draw (X) | 3.20 | KSh 320.00 | KSh 220.00 |
| AFC Leopards win (2) | 3.60 | KSh 360.00 | KSh 260.00 |

Make we say you put KSh 100 as stake (di money wey you bet) on Gor Mahia at 2.10.

If Gor Mahia win 2–1, you go collect KSh 100 × 2.10 = KSh 210. Na your KSh 100 back, plus KSh 110 profit.

If di match draw or AFC Leopards win, your KSh 100 don go.

## Wetin be decimal odds?

Decimal odds na one number wey show your total return for every 1 unit wey you stake. Na im people dey use pass for Nigeria, Kenya, Ghana, South Africa, Uganda and Tanzania.

Di formula no hard:

- **Return** = stake × odds
- **Profit** = return − stake

Example: GH₵10 at odds 1.80 go return GH₵10 × 1.80 = GH₵18. Your profit na GH₵18 − GH₵10 = GH₵8.

Your stake dey always inside di return. Na why decimal odds no dey ever go below 1.00.

## Wetin be fractional odds, and how you go turn am to decimal?

Fractional odds dey show your profit compared to your stake, like 5/2. You go read 5/2 as "five to two". E mean say for every 2 units wey you stake, you go get 5 units profit.

To turn fractional odds to decimal, divide di top number by di bottom number, then add 1.

So 5/2 go be (5 ÷ 2) + 1 = 2.5 + 1 = 3.50.

| Fractional | How we take calculate am | Decimal |
|---|---|---|
| 1/2 | (1 ÷ 2) + 1 | 1.50 |
| 1/1 (evens) | (1 ÷ 1) + 1 | 2.00 |
| 11/10 | (11 ÷ 10) + 1 | 2.10 |
| 6/4 | (6 ÷ 4) + 1 | 2.50 |
| 2/1 | (2 ÷ 1) + 1 | 3.00 |
| 5/2 | (5 ÷ 2) + 1 | 3.50 |

You dey add 1 becos decimal odds carry your stake inside. Fractional odds no carry am.

## How you go turn odds to implied probability?

Implied probability na di chance wey di odds dey show for one result. To get am, divide 1 by di decimal odds, then multiply by 100.

Make we use di Gor Mahia example for up:

- Gor Mahia win at 2.10: 1 ÷ 2.10 = 0.4762, so about 47.62%
- Draw at 3.20: 1 ÷ 3.20 = 0.3125, so 31.25%
- AFC Leopards win at 3.60: 1 ÷ 3.60 = 0.2778, so about 27.78%

Dis na wetin di bookmaker reason, no be fact. Teams fit beat dis numbers, and dem dey beat am. Read more for our guide on [implied probability](https://oddsclass.com/learn/implied_probability/).

## Why odds no dey di same for every bookmaker?

Odds dey different becos each bookmaker dey set dia own price and add dia own margin. Di margin (di profit wey bookmaker don hide inside di odds) na di main reason.

Add di three implied probabilities from di example:

47.62% + 31.25% + 27.78% = 106.65%

If di book fair, e for add up to exactly 100 percent. Di extra 6.65% na di margin. E mean say di odds for every result small pass di "fair" price small.

Bookmaker wey get smaller margin go give odds wey high small. Dem also dey react to news and bets for different speed. Na why one site fit show 2.10, and another one show 2.05, for di same team.

## Wetin low odds and high odds mean?

Low odds mean say di bookmaker reason say di result fit happen, so e no go pay much. High odds mean say di result no too likely, so e go pay more.

See am with R20 stake:

| Odds (example odds) | Implied probability | Wetin you go collect for R20 | Profit for R20 |
|---|---|---|---|
| 1.25 | 80.00% | R25.00 | R5.00 |
| 2.00 | 50.00% | R40.00 | R20.00 |
| 5.00 | 20.00% | R100.00 | R80.00 |

Low odds no mean say di bet safe. Even at 1.25, di odds dey show say di result go fail about 1 time out of 5.

High odds no be "better value" automatically too. Big money for something wey hardly happen, most times e go still end as loss. To check your own figures, use our [payout calculator](https://oddsclass.com/tools/payout_calculator/).

## Mistakes wey people dey make

- **To forget say stake dey inside di return.** Odds 2.10 for KSh 100 go give KSh 110 profit, no be KSh 210 profit.
- **To think say low odds safe.** Favourite for 1.25 fit still lose.
- **To take implied probability as di real chance.** Na di bookmaker guess, and di margin dey inside.
- **To turn fraction to decimal wrong.** Always add 1 after you divide. 2/1 na 3.00, no be 2.00.
- **To ignore small price difference.** Small gap like 2.05 vs 2.10 dey change wetin you go collect for every bet.
