Esports Match Win Probability Calculator

What this page can answer

For this market, the calculator asks whether the entered data can convert a user-entered rating difference into a fair win probability and price. Defaults demonstrate the form rather than a typical market.

Both participants must use one rating scale and the same event conditions.

Reading the formula

For this market, the calculation uses win probability = logistic((selected rating − opponent rating + adjustment) ÷ scale).

Venue, surface, confidence, and form should move the baseline only when they add new information.

Double counting occurs when the rating already reflects the same factor.

Under the entered assumptions, an arithmetic check does not validate the underlying evidence.

Input scope and units

For estimated win probability, Selected side rating represents power rating for the selected side. At this stage, use a current source for Opponent rating. Here it means power rating on the same scale.

Venue or surface adjustment records positive values favor the selected side. Rating points per logistic step belongs to the same period as the other entries. It is controls how strongly rating differences affect probability.

For the saved case, a source revision should stay visible rather than being blended into an unrelated adjustment.

Scenario testing

• In the current scenario, create a neutral case before applying the full change to Rating points per logistic step.
• When using the result, shrink a small-sample rating gap toward the broader baseline.
• On this page, a large fair-price swing signals sensitivity to scale or confidence.

Checks the arithmetic cannot perform

Fair price expresses model probability. It does not independently validate the rating.

Within this calculation, a format, roster, patch, or equipment change can alter an input even when its number is unchanged.

In the current scenario, use rules and participant information for the exact league, tournament, map, set, race, or innings being priced.

Following the calculation

When using the result, these numbers demonstrate how fields flow into the answer.

Begin with Selected side rating at its loaded example value and keep the other displayed defaults.

Method: win probability = logistic((selected rating − opponent rating + adjustment) ÷ scale).

Within this calculation, a clean reproduction is not evidence that the inputs are accurate.

Interpreting the displayed value

A large market difference deserves a calibration review.

Rating scale and confidence are common sources of disagreement.

On this page, a difference should survive one reasonable adverse case.

A useful calculation record

When using the result, start a new case when period, participant, settlement rule, or source definition changes.

In the current scenario, another reader should be able to repeat the calculation.

Settlement and data limitations

• The rating scale must be calibrated to the sport and competition.
• For the selected event, check event length, tie or overtime procedure, participant requirements, and the sportsbook void policy.
• In this model, a precise answer does not reduce uncertainty in undocumented inputs.
