Enter a stake in Tanzanian shillings and two or three quoted decimal prices. Use 1 in the third field for a two-selection accumulator.
Formula and worked example
Combined decimal price = price 1 × price 2 × price 3. Gross return = stake × combined price. Net profit excludes the original stake.
For TZS 1,000 at prices 1.80 and 2.10, the combined price is 3.78. If both selections win and the bet settles at those prices, the gross return is TZS 3,780 and net profit is TZS 2,780, before any applicable deductions.
What the calculation means
The combined probability assumes independent events. Correlated selections may be restricted or priced differently. Returns include stake.
The displayed implied probability comes from the combined quoted price. It is not a measured chance that all selections will win. Voids, taxes and other settlement adjustments are not included.
Football markets and accumulator rulesEducational estimates only; no outcome is guaranteed. For adults where lawful. Set limits and never chase losses.
Try another worked scenario
Load an example, then select Calculate. These hypothetical inputs remain editable before calculation.
Combined price 5.40; winning gross return TZS 54,000; net profit TZS 44,000.
Conditional revised price 2.70; winning gross return TZS 27,000; net profit TZS 17,000.
Combined price 3.78; winning gross return TZS 18,900; net profit TZS 13,900.
The void-leg example assumes the applicable rules replace that leg with 1.00. A builder or promotion may use a different rule. Price multiplication does not check whether related selections are accepted and does not estimate their joint probability.
