Formula and calculation
Estimate an accumulator’s normal payout and the capped refund available when exactly one leg loses under selected insurance terms.
Combined odds = product of leg odds. Eligible refund = min(stake × refund rate, refund cap), only under an exactly-one-loser insurance condition.
Values are informational. Operator rules, limits, voids and rounding may change an official settlement.
Worked example
A $20 treble at 1.80, 1.90 and 2.10 has combined odds 7.182 and potential return $143.64. A 100% refund capped at $20 is $20.

FAQ
Does this accumulator insurance 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.
