Decoy Score · the Asymmetric Dominance Score

Is your middle tier actually a decoy? Find out in 90 seconds.

Decoy Score by PricingAutopsy is a SaaS decoy pricing tier calculator that computes the Asymmetric Dominance Score (ADS) — a transparent 0–100 index measuring how hard your middle tier works to make your target tier feel inevitable. It is the only tool that scores your real numbers against a formula grounded in Huber, Payne & Puto (1982) and benchmarks them against 47 hand-analyzed SaaS pricing structures.

The 47-company benchmark dataset

Each row is a real SaaS pricing structure with tier prices and feature counts manually extracted, then scored with the same ADS formula your inputs run through. Sort yourself against the field.

Prices reflect published list pricing captured during analysis (2024–2026); they change frequently and are illustrative of structure, not current quotes. Feature counts are PricingAutopsy’s manual tally of marketed features per tier.

How the Asymmetric Dominance Score is computed

No black box. The ADS is a weighted composite of six sub-dimensions, each calibrated against the decoy-effect literature and the 47-row dataset above.

weight 24%

1 · Price Ratio Spread

Middle price as % of high price. Peak score in the 52–68% band — where the mid feels like the rational anchor.

weight 22%

2 · Feature Asymmetry Index

How much more the mid shares with the high tier than the low tier. The closer mid leans to high, the stronger the pull up.

weight 18%

3 · Decoy Obviousness Penalty

If the mid price sits within 15% of either neighbor, the decoy reads as manipulation — score penalized hard.

weight 16%

4 · Value-Per-Dollar Gradient

Does features-per-dollar drop at the high tier? A sharper drop makes the mid look like the sensible buy.

weight 10%

5 · Tier Name Anchoring

Aspirational names (Pro, Business, Growth) on the mid tier signal upgrade; adequacy names (Basic, Lite) flatten it.

weight 10%

6 · Upgrade Friction Delta

Feature gap between mid and high. Too small = no pull; too large = fear. Optimal gap is moderate.
