Grow a Garden Calculator

Most players land here with one decision: price a harvest, check a pet's future weight, or judge a Discord trade. Use the grid below after you know that decision — do not open every tool at once.

1. Values or trades: price crops on grow a garden values, then compare both sides with trading values / WFL.
2. Pets: start with the gag pet calculator hub or jump straight to weight, XP, hatch, or tier tools.
3. Mutations: stack tags in the mutation calculator, then confirm Sheckles in crop value.
4. Rare pets: run the dupe calculator before you accept — a Fair WFL does not clear a flagged serial.
5. After a numbered patch, read the changelog so you know which dataset the tools are drawing from.

AdSense and players both reject empty hub pages. These examples use the same constants as the live tools so you can verify the result yourself.

Example 1 — Pet weight at age 100

A pet that hatches at 5.5 kg follows W = (5.5 ÷ 11) × (age + 10). At age 50 that is 30 kg. At age 100 that is 55 kg — exactly ten times hatch weight. Traders often list "5.5 hatch / age 50"; this calculator removes the chat arithmetic before you open WFL.

Example 2 — Crop weight is squared

Crop Sheckle value scales with weight² before mutations. If two harvests share the same crop and mutations, a 2 kg crop is worth four times a 1 kg crop on the weight factor alone. That is why guessing weight in Discord causes bad trades — measure first, then open the crop value calculator.

Example 3 — WFL ±10% band

If you offer 1,000,000 Sheckles of value and receive 1,050,000, the ratio is 1.05 → Fair on this site (±10%). Receive 1,150,000 (1.15) → Win. Receive 850,000 (0.85) → Lose. The label only reflects the numbers you enter; it does not invent market demand.

Example 4 — Hatch speed cap

Helper hatch boosts add together and stop at 90% reduction. A 60-minute egg at the cap finishes in 6 minutes. Extra hatch pets past the cap waste roster slots you could use for mutation or XP roles — check the egg hatch calculator before you over-equip.

Match the tool to the decision. Opening the wrong page is how players misprice pets as if they were NPC crops — or treat WFL as a market guarantee.

Prefer tabs in one session? Use the all-in-one calculator. That hub is not a second homepage — the broad "grow a garden calculator" directory stays here.

Every calculator mirrors documented site constants. If an in-game prompt disagrees after you verified the patch, send a screenshot through contact.

• Pet weight: W = (hatchWeight ÷ 11) × (age + 10). Reverse: hatchWeight = (currentWeight × 11) ÷ (age + 10).
• Crop value (classic GAG): base × weight² × growth mutation × environmental bracket × (1 + friend boost). Growth mutations do not stack with each other — highest wins.
• Env bracket: 1 + (sum of env multipliers − count of env tags). Do not multiply Shocked × Celestial as a raw product.
• Egg hatch: baseMinutes × (1 − min(0.9, sum of helper boosts)).
• WFL: received ÷ offered — Win ≥ 1.1, Fair 0.9–1.1, Lose < 0.9.
• Pet XP: cumulative curve floor(20 × age^2.02); time estimates use your effective XP rate.

Classic Grow a Garden and Grow a Garden 2 do not share one price table. Mixing them is a common source of "calculator wrong" reports.

How we keep pages useful after patches

When a numbered update ships, we prioritize new pets, crops, mutations, and weather rows, then re-check formulas that community reports say have moved. The changelog is the version ceiling for what the tools claim to cover. Temporary gaps are better than silent wrong numbers.

• Treating current pet weight as hatch weight when ages differ.
• Multiplying every mutation together instead of using growth exclusivity + env bracket.
• Calling a trade Fair from vibes without entering both Sheckle totals.
• Skipping serial checks on rare pets because WFL looked fine.
• Using classic GAG crop math on Grow a Garden 2 harvests.

Strategy context lives in the guides below — calculators give numbers; guides explain when those numbers matter.
