Trade calculator
Put together the two offers and compare what you deliver with what you receive.
You give
Choose a pet to start.
You receive
Choose a pet to start.
Add pets to both sides
The result appears when both offers are filled.
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.
