Trade Value Formula Explained

The Grow a Garden trade value formula computes a numerical value score for each pet based on its rarity tier and current level. Comparing these scores determines trade fairness.

Value Score = base_value × rarity_multiplier × level
Trade Ratio = Side A Value / Side B Value

Rarity Multiplier Reference for Trading

RarityValue MultiplierBase ValueExample (Level 10)
Common1001,000
Rare1002,000
Epic1003,000
Legendary1005,000

A trade ratio of 1.0 indicates perfectly balanced value. Ratios between 0.85 and 1.15 are generally considered fair. Values outside this range suggest one party is receiving significantly more value.

How Trade Evaluation Works in Grow a Garden

Evaluating a pet trade requires understanding the underlying value mechanics. Follow this framework to assess any proposed swap:

  1. Identify both pets' rarity tiers — Determine whether each pet is Common, Rare, Epic, or Legendary to apply the correct value multiplier.
  2. Note each pet's current level — The level directly scales the value score; higher-level pets carry proportionally more trade weight.
  3. Compute value scores — Use the formula: value = 100 × rarity_multiplier × level for each pet.
  4. Calculate the trade ratio — Divide Side A's value score by Side B's value score to obtain the ratio.
  5. Interpret the ratio — A ratio near 1.0 is fair. Above 1.15 favors Side A. Below 0.85 favors Side B.
  6. Make an informed decision — Use the computed ratio alongside your personal strategy to accept, decline, or negotiate the trade.

Grow a Garden Trade Calculation Examples

Example 1: Fair Trade — Rare Level 15 for Epic Level 10

Side A: Rare Level 15 | Side B: Epic Level 10

Side A: 100 × 2 × 15 = 3,000
Side B: 100 × 3 × 10 = 3,000
Ratio: 1.00 — Perfectly Fair Trade

Example 2: Favorable to Side A — Legendary Level 8 for Rare Level 12

Side A: Legendary Level 8 | Side B: Rare Level 12

Side A: 100 × 5 × 8 = 4,000
Side B: 100 × 2 × 12 = 2,400
Ratio: 1.67 — Side A is overpaying significantly

Example 3: Slightly Favorable to Side B — Common Level 20 for Epic Level 4

Side A: Common Level 20 | Side B: Epic Level 4

Side A: 100 × 1 × 20 = 2,000
Side B: 100 × 3 × 4 = 1,200
Ratio: 0.60 — Side B is receiving more value

Trade Fairness Guidelines for Grow a Garden

Understanding trade fairness thresholds helps you make smarter swapping decisions. Use these guidelines alongside the calculator to evaluate every trade opportunity.

Trade Ratio Interpretation

Ratio RangeVerdictWhat It Means
0.85 – 1.15Fair TradeBoth sides are exchanging roughly equal value. This is a balanced swap.
1.15 – 1.50Favors Side ASide A is giving more value than they receive. Consider asking for additional items.
0.50 – 0.85Favors Side BSide B is receiving more value. Side A should renegotiate or decline.
Above 1.50Highly UnbalancedSignificant value gap. Strongly reconsider this trade unless strategic reasons apply.
Below 0.50Highly UnbalancedSide A is receiving far less value. This trade is generally not recommended.

Note: Value scores are quantitative estimates. Subjective factors like sentimental attachment, breeding potential, and collection goals may influence your final decision beyond pure numerical value.

People Also Ask About Grow a Garden Trading

Fair trade values are determined by computing each pet's value score using the formula: base value (100) multiplied by the rarity multiplier and the pet's level. Common pets use a 1x multiplier, Rare 2x, Epic 3x, and Legendary 5x. Comparing the two scores produces a trade ratio; a ratio between 0.85 and 1.15 generally indicates a fair swap.
Four rarity multipliers directly impact pet trade values: Common pets use a 1x multiplier, Rare pets use 2x, Epic pets use 3x, and Legendary pets use 5x. These multipliers scale the base value of 100 per level, meaning a Level 10 Legendary pet is worth 5,000 compared to a Level 10 Common pet at 1,000 — a fivefold difference in trade value.
Yes, bundle trades are common. To evaluate multi-pet trades, calculate each pet's value score individually and sum them for each side. For example, trading two Rare Level 10 pets (2,000 + 2,000 = 4,000) for one Legendary Level 8 pet (4,000) would be a perfectly fair trade with a 1.0 ratio.
Pet level has a direct linear impact on trade value. The value score formula multiplies the base value, rarity multiplier, and the pet's current level. A Level 20 Rare pet (4,000) is worth exactly twice as much as a Level 10 Rare pet (2,000) of the same rarity. Leveling pets before trading is a reliable way to increase their trade worth.
A trade ratio between 0.85 and 1.15 is considered a good, fair trade in Grow a Garden. A ratio of exactly 1.0 means both sides have identical computed value. Ratios below 0.85 indicate Side A is undervalued, while ratios above 1.15 mean Side A is overpaying. Always aim for trades within the 0.85–1.15 range for equitable exchanges.

Frequently Asked Grow a Garden Trading Questions

Yes. The trading calculator includes all four pet rarity tiers: Common (1x), Rare (2x), Epic (3x), and Legendary (5x). Each rarity uses its specific value multiplier to ensure accurate trade comparisons between any combination of pet types.
Absolutely. Cross-rarity trades are the most common use case. The calculator handles any rarity combination — Common for Legendary, Epic for Rare, or any other pairing. The value score formula normalizes all pets to a common scale, making cross-rarity comparisons straightforward and reliable.
When both pets share the same rarity tier and level, their value scores are identical, producing a trade ratio of exactly 1.0. This indicates a perfectly balanced trade. However, individual preferences and strategic goals may still influence your decision beyond pure numerical equality.
The value score calculation is based on established Grow a Garden rarity multipliers and level scaling mechanics. While the formula provides a reliable quantitative framework, actual trade values may fluctuate based on market demand, seasonal events, and community trends. Use the calculator as a strong baseline reference.
Yes, many players use both tools in tandem. First, use the Grow a Garden Pet Calculator to plan resource needs for leveling pets. Then, use this trading calculator to evaluate the improved trade value of your leveled pets. Combining both tools maximizes your overall pet economy strategy.
The base value score focuses on rarity and level. Breeding potential adds subjective value beyond the numerical score. A pet near its breeding threshold may carry extra strategic worth. Consider using the pet calculator to check breeding eligibility and factor that into your trade decisions alongside the computed value score.

Grow a Garden Trading Glossary

Value Score

A numerical representation of a pet's trade worth, calculated by multiplying base value, rarity multiplier, and current level.

Trade Ratio

The quotient of Side A's value score divided by Side B's value score. A ratio of 1.0 indicates equal value on both sides of the trade.

Rarity Multiplier

A scaling factor applied to base value: Common=1x, Rare=2x, Epic=3x, Legendary=5x. Higher rarities command exponentially greater trade value.

Fair Trade Range

The ratio band between 0.85 and 1.15 where both parties exchange roughly equivalent value. Trades within this range are considered balanced.

Bundle Trade

A trade involving multiple pets on one or both sides. Total value is the sum of individual pet value scores for each side.

Cross-Rarity Trade

A swap between pets of different rarity tiers, such as trading a Legendary pet for multiple Common or Rare pets of equivalent total value.

Overpay

When one side of a trade offers significantly more computed value than they receive, indicated by a ratio above 1.15 or below 0.85.

Trade Verdict

The final assessment of a proposed trade: Fair, Favorable to Side A, or Favorable to Side B, based on the computed trade ratio.
