What is the wheel score used in the OptionIncomeTools wheel screener?

The wheel score is a 0–100 composite that ranks an underlying for the wheel strategy by combining premium efficiency, liquidity, and assignment-risk-adjusted yield; it is a screening heuristic, not a forecast.

Calculation type: Heuristic score Method version: 1.0 Date reviewed: 2026-06-23

Formula

A weighted average of three sub-scores (each 0–100):
  50% × annualized screen yield (normalized)
  30% × liquidity score
  20% × assignment-risk score (lower delta = higher score)

Worked example

SOFI scores 72 because its annualized screen yield is in the top quartile of our universe (yields 85), its liquidity score is 78, and its assignment-risk score is 50 due to a 0.30 short put delta. Composite = 0.5(85) + 0.3(78) + 0.2(50) = 72.

Common misinterpretation

Treating wheel score as a quality score or a prediction of profit. It is a relative ranking inside our screened universe under the current snapshot. A wheel score of 75 today may be 55 tomorrow if implied volatility falls or assignment risk rises.
