## How to interpret

W — Gain: the offer received exceeds the one delivered according to the chosen criteria. F — Balance: the difference is less than 10%. L — Loss: the offer received is lower than the one delivered.

The difference is calculated relative to the greater total of both sides. In combined mode, we calculate the difference in income and rarity separately and apply the weight you choose. A rarity score does not equate to money.

Income, weight and mutations

We use the base income from the catalog and add the bonuses from the mutations above ×1: Golden and Rainbow together give ×5. For size, enter the current weight and reference weight of the species; without both, we do not apply size bonuses. The size model uses Scale = ∛(kg / kg_ref), Scale^1.85 up to Scale 5 and a reduced curve above that point. It is a community estimate.

If you know the final income shown in the game, fill in “Final Income in the Game”. This value replaces the estimate and must already include weight and mutations. Pets without confirmed income require this amount to compare by income.

Rarity scoring rule

Common starts at 1 point and each rarity doubles the previous one, up to Divine with 512. Available: ×1; rotation or store: ×1.25; limited: ×2; unavailable: ×3. For limited and unavailable, weeks reported increase by 10% per week, up to 50%. Mutation bonuses are added above the base: Silver ×1.5; Golden ×2; Rainbow ×4; Bloom, Parasite, Fractured and Scrambled ×3.

Availability and age are manual choices for your simulation. We do not assume that a pet is out of circulation. These weights are comparison rules and not official market values.

The result compares the selected criteria. Demand, player preference and actual availability can change the negotiation. Check out the pets and income in the game before deciding.

## Headless Horseman

The panel advertises $8.5B/s (8.5 billion per second). This is not a controlled base-income measurement. Weight and mutations can change a specimen’s income. Tools keep base income unconfirmed and require your specimen’s actual income when needed.[Headless Horseman →](/en/pets/headless-horseman/)

The income figures have not been normalized for weight and modifiers. They are displayed as income, not proven base income. Do not use them to derive a weight formula.
