Grow a Garden Pet XP Calculator

Pets accumulate XP over time based on their species and their Age level. Higher age pets produce more XP/sec and often have stronger passive effects. The XP-to-level curve is steep: Level 1→5 costs 250 XP, but Level 75→100 costs 115,000 XP, so pushing a pet to Max takes a meaningful time investment even with boosts.

Shiny (+15%), Inverted (+50%), Golden (+10%), Rainbow (+20%), and Radiant (+25%) all modify effective XP/sec. Shiny is the most common mutation (~32% drop chance) while Inverted is rarer but gives the biggest single-mutation boost. Only one mutation rolls per pet.

Yes. Friend Boost, Food XP boosts, and pet mutation XP bonuses all stack multiplicatively on the pet's base XP/sec rate. A Shiny pet (+15%) with a 25% friend boost and a +20% XP food running effectively earns 1.6× base XP/sec.

Leave the pet equipped 24/7 so it accumulates XP while offline (pets continue earning while you're away), use a Shiny or Inverted mutation pet if you have one, stack friend boost by tending friends' gardens, and feed any XP-boost food consumable when stacking toward a level goal. Most mid-tier pets reach Level 75 in 3-5 days of continuous use with a 50% effective boost.
