Combat Sports Value Calculator

What the headline measures

Combat Sports Value Calculator is designed to compare a combat-sports probability estimate with the offered price. For the selected event, another period or grading basis is a different question.

Combat Sports Value depends on the event scope represented by Estimated win probability and Reference stake.

Where input quality can fail

In this model, a material participant, format, or source change requires a new expected value baseline.

For this comparison, a difficult weight cut, replacement opponent, or round-format change warrants a new calculation.

As a practical check, weigh-in information, reach, pace, style matchup, recent activity, and judging format should refer to the scheduled bout.

How to source the fields

Estimated win probability is a separate input defined as your probability estimate.

Sportsbook decimal odds is a separate input defined as available market price.

For expected value, Reference stake represents stake used to express expected profit.

Within this calculation, confirm that the baseline and adjustment did not both come from the same news.

How the formula works

Formula: expected profit = probability × profit − loss probability × stake.

Stake and quoted prices determine return, profit, or allocation.

The formula cannot verify that every price remains executable.

On this page, use a separate scenario for a plausible upper or lower assumption.

Comparing two plausible cases

• Keep stake fixed and compare the accepted price with one realistic adverse quote.
• For promotions or hedges, test the actual eligible maximum.
• Do not change multiple prices when identifying the source of a return difference.

Reproducing the method

When using the result, this worked case verifies the method without describing a typical market.

For the Combat Sports Value Calculator, the values below differ from the form defaults. In the current scenario, they make the method checkable and do not describe a recommended or typical wager.

Estimated win probability is 58.8%. Sportsbook decimal odds is 2.337. Reference stake is $108.

Applying the Combat Sports Value rule: expected profit = probability × profit − loss probability × stake.

• Expected ROI: 37.42%
• Break-even rate: 42.79%

For this expected value example, a mismatch usually comes from units, rounding, a sign error, or a different option selection. Within this calculation, check those items first.

On this page, reproduction confirms arithmetic, not event assumptions.

The answer is exact only for the entered prices and terms.

Recalculate after a quote, limit, or eligibility change.

In this model, compare only after confirming same event, selection, and settlement period.

Practical limitations

• Method, round, and settlement rules require separate modeling.
• For the selected event, verify scheduled rounds, no-contest treatment, method definitions, and the official-result policy.
• As a practical check, the calculation cannot verify whether every source was collected at a compatible time.

Do not force significant strikes prop into an unrelated field. The Significant Strikes Prop provides its method.

When to update the page

Store expected value with event, selection, compared line, time, and source for Estimated win probability.

For this comparison, start a new case when period, participant, settlement rule, or source definition changes.

At this stage, keep source revisions and market moves as different update reasons.
