What this tool calculates
Summarize betting profit or loss from total returns and total stakes, then calculate ROI and the proportion of stakes recovered.
Net profit or loss = total returns − total stakes. ROI = net profit or loss ÷ total stakes × 100%.
Inputs are processed locally in your browser. Verify market definitions and settlement terms before relying on a result.
Worked example
With 1,000 staked and 1,120 returned, net profit is 120 and ROI on stakes is 12%.

FAQ
How is the profit and loss calculated?
Net profit or loss = total returns − total stakes. ROI = net profit or loss ÷ total stakes × 100%.
Does the result include bookmaker margin?
Only when the displayed formula explicitly uses market odds. Model probabilities and projections are based solely on the values entered.
Why can my bookmaker settlement differ?
Operators may use different rounding, void, dead-heat, minimum-stake, or market settlement rules. Check the rules for the specific bet.
How much precision does the calculator use?
Calculations use JavaScript floating-point precision and are rounded only for display, normally to two or four decimal places.
Can this result predict a winning bet?
No. It calculates a mathematical scenario from your inputs and does not account for every source of uncertainty or guarantee an outcome.
