Formula and calculation
Build a finite loss-recovery staking sequence from a starting stake, decimal odds, and maximum number of consecutive losses.
Next stake = (accumulated losses + target profit) ÷ (decimal odds − 1). Each value is rounded up to the nearest cent.
Values are informational. Operator rules, limits, voids and rounding may change an official settlement.
Worked example
With a $10 start at 2.00 odds, six stakes are $10, $20, $40, $80, $160 and $320; total exposure is $630.

FAQ
Does this martingale sequence calculator predict an outcome?
No. It performs transparent arithmetic on the values you enter and does not use live data or predict an event.
Why can operator settlement differ?
House rules can define voids, pushes, commissions, promotion eligibility, and rounding differently. Check the rules attached to the wager.
When does the calculator round values?
Calculations retain JavaScript numeric precision and displayed money is rounded to two decimal places only at the output stage.
Can I use American or fractional odds directly?
No. This page expects decimal odds where an odds field appears. Convert other formats before entering them.
Are the results stored or transmitted?
No. The calculation runs locally in your browser and the page does not upload the values you enter.
