Bet Profit & Payout Calculator
Use this bet calculator to translate decimal odds into precise payouts before placing any stake. It estimates gross return, net profit after exchange commission, optional withholding tax on winnings, and critical efficiency indicators such as ROI and implied probability, helping bettors evaluate whether a wager truly offers value compared to their projected win probability.
How the calculator works
The computation multiplies the entered stake by your chosen decimal odds to produce the gross return. The gross profit equals that return minus the original stake. A commission (common on exchanges) is applied only when there is a positive profit, followed by any withholding tax on the remaining winnings. The final net profit and total payout reflect those deductions, while ROI expresses the percentage gain or loss relative to the stake. Implied probability is calculated as 100 divided by the decimal odds, showing the break-even hit rate the market believes is required.
Example scenario
Imagine staking 60 on a team priced at 2.45 with a 5% commission and 10% tax. Gross return would be 147.00 and gross profit 87.00. Commission would remove 4.35, tax would take 8.25, leaving a net profit of 74.40 and a total cash payout of 134.40. If you estimate the true win probability at 45%, the wager would hold an edge because the implied probability at 2.45 odds is 40.82%.
