Example scenarios: bet slip calculation
These are calculations built with example odds — not real matches or predictions. The numbers come from the same engine as the tool above.
Scenario 1
4-match accumulator, if all win
Odds 1.40 × 1.65 × 1.90 × 2.10 · stake 50.00 TL
- Total odds 9.22.
- Return 460.85 TL, net profit 410.85 TL.
Scenario 2
6 low-odds selections
Odds 1.20 × 1.25 × 1.30 × 1.15 × 1.35 × 1.22 · stake 100.00 TL
- Even though each is low, the total odds become 3.69; potential return 369.34 TL, net 269.34 TL.
- All six selections must win for the slip to pay out; adding selections raises the odds but makes the slip harder to win.
Scenario 3
3-match accumulator, if one match loses
Odds 1.85 × 2.40 × 1.70 · stake 20.00 TL
- Total odds were 7.55, potential return 150.96 TL.
- Because selection 2 lost, the slip loses: return 0.00 TL, net -20.00 TL.
- Had the same three selections been played as a 2/3 system, one of the 3 columns would have won — see the system calculator.
How are bet slip odds calculated?
The total odds of an accumulator are the product of the odds of all selections on the slip. For example, three selections at 1.50, 2.00 and 1.80 give total odds of 5.40. The potential return is these total odds times the stake: 540.00 TL on a 100.00 TL slip. For the net profit, subtract the stake from the return. The calculator does not round the odds in intermediate steps; it only rounds the TL amount to two decimal places.
Total odds = odds₁ × odds₂ × … × oddsₙ Potential return = total odds × stake Net profit = potential return − stake
Example: odds 1.50 × 2.00 × 1.80 = 5.40. With a 100.00 TL stake, the potential return is 540.00 TL, net profit 440.00 TL. If any selection loses, the slip loses and the result is -100.00 TL.
The tool does not round odds in intermediate steps. Three odds of 1.15 multiply to 1.520875; the screen shows 1.52 but the return of a 10.00 TL slip is calculated from the exact product and rounded to two decimal places: 15.21 TL.

What is the difference between an accumulator and a system bet?
An accumulator is a single column: if every selection wins it pays out at the total odds, and if a single selection loses the slip loses. A system bet splits the same selections into several columns; the cost rises with the number of columns, but some columns can win even if a selection loses. With four selections, an accumulator is 1 column, a 2/4 system 6 columns and a 3/4 system 4 columns.
| With 4 selections | Columns | First return |
|---|---|---|
| Accumulator | 1 | 4 winning |
| 3/4 system | 4 | 3 winning |
| 2/4 system | 6 | 2 winning |
You can find the number of columns and the cost of a system bet with the iddaa System Bet Calculator.

From calculation to analysis
The calculator only shows the maths of the slip; it does not tell you how reasonable the selections are. To compare a match's markets with past matches by opening odds, use Auto Analysis; for all analysis tools, use the Analysis Hub.
Responsible gambling
This calculator only does the maths; it never says any result will win and promises no winnings. As the number of selections grows the total odds rise, but the slip's chance of winning falls. Set your budget in advance; people under 18 may not bet. For details, see the Responsible Gambling page. See the iddaa.com rules for official rules and limits.
Frequently asked questions
How are iddaa bet slip winnings calculated?
In an accumulator, the odds of all selections are multiplied to get the total odds; the potential return is the total odds times the stake. For example, three selections at 1.50, 2.00, 1.80 with 100.00 TL give total odds of 5.40 and a potential return of 540.00 TL.
What is the difference between net profit and potential return?
The potential return is the total amount paid out, stake included. The net profit is what remains after deducting the stake you placed. In the example: 540.00 TL − 100.00 TL = 440.00 TL.
What happens if one match on the slip loses?
In an accumulator, a single losing selection means the whole slip loses; the return is zero. For a structure where some columns can still win when a selection loses, use a system bet.
How are the stake and return rounded?
The calculator does not round the total odds in intermediate steps; it displays them with two decimals. The potential return is calculated from the exact product and only the TL amount is rounded to two decimal places. So multiplying the two-decimal odds on screen by hand can differ by a few hundredths.
Can I enter odds with a comma?
Yes. You can type odds as 1.85 or 1,85; the calculator reads both as the same number.
Does the calculator apply iddaa's official limits?
No. The tool only does the maths of odds and returns; see the iddaa.com rules for official rules and limits such as maximum winnings or minimum stake. A calculation is not a promise of winnings.
