Odds Boost Value Calculator
Measure the extra expected value created by an odds boost. Executable prices, limits, promotion terms, commission, and timing determine whether an allocation is available.
Inputs for expected boost value
Replace every default with a value for the same event and settlement period.
The question behind the result
This page calculates Expected boost value from the visible Stake and Original American odds entries. The output applies only to the scenario and market boundaries stated on the form.
For this market, use an executable price for the exact selection and stake, not an earlier screenshot or an unavailable best quote.
How to source the fields
Stake records amount wagered with the boost.
For expected boost value, Boosted American odds represents enter positive or negative American odds.
At this stage, use source precision during calculation and round only the display.
Separate the current output from the closing line value work on Closing Line Value, without substituting its answer for an input on this page.
How the formula works
Formula: boost value compares expected profit at the original and boosted prices.
Which input should be tested first
After documenting expected boost value, the Round Robin Bet can answer another question.
Worked example with different inputs
In the current scenario, these numbers demonstrate how fields flow into the answer.
Boundaries of the calculation
Stake caps and excluded markets can limit the usable value.
In the current scenario, a precise answer does not reduce uncertainty in undocumented inputs.
To compare sports arbitrage separately, open the Sports Arbitrage after saving this baseline.
A useful calculation record
The evidence behind this scenario
A boundary check should cover realistic low and high values for Stake, not arbitrary extremes. Hold Original American odds steady during that test. If Expected boost value crosses the relevant line throughout a defensible range, the conclusion is sturdier than one supported by a single point estimate.
Document why Boosted American odds belongs in this calculation instead of merely recording its number. A short reason—role change, venue effect, price quote, or observed rate—helps another reader understand how it relates to Original American odds and why Expected boost value changed from the baseline.
Results from different calculators should be compared only after their event scopes align. Match the participant, period, and settlement treatment behind Boosted American odds and Estimated win probability; then compare Expected boost value. Otherwise the apparent difference may come from two tools answering different questions.
Revisit this page when the evidence supporting Estimated win probability or Stake changes materially. Keep the earlier Expected boost value in the record, add the new source and timestamp, and rerun the same method. That sequence distinguishes updated information from silent changes to the calculation process.
Input and settlement questions
On this page, which field should be tested first in Odds Boost Value?
Before using the result, should stake be rounded before entry for Odds Boost Value?
Can expected boost value prove that a wager has value for Odds Boost Value?
The output is only as reliable as Stake, Original American odds, and the market definition. Ordinary event variance remains outside the formula.
In Odds Boost Value, what if the market covers a different period?
For this comparison, create another calculation for that period instead of scaling the old answer mechanically.
