Pick your pet, enter its current age and the age you want to reach, and this calculator returns the real time required at that pet's actual XP-per-second rate — with mutation multipliers and active XP buffs applied. If you only need the raw XP totals between two levels, use the Pet XP Calculator instead.
Pets gain XP passively while equipped and level up through ages. Each age costs progressively more XP than the last, so the jump from age 40 to 50 takes far longer than 1 to 10. Reaching age 50 requires roughly 50,000 total XP, and your pet's base XP-per-second plus any mutation and buff multipliers determines how quickly you get there. Pets can keep aging past 50 up to 100.
Time = XP needed ÷ effective XP per second. Effective XP/s is your pet's base rate multiplied by its mutation multiplier and any active buff, plus any extra flat XP/s you add. Because rarer pets have much higher base XP rates, the same age gap can take hours on a Mythic pet or days on a Common one.
Roughly 50,000 total XP. The real time depends on your pet's XP-per-second, its mutation multiplier, and any active buffs — this calculator returns the exact figure for your setup.
Yes. Higher-age pets are worth more because age represents time invested, and age also drives weight, which carries its own trade premium.
Pets gain XP while equipped and active. Plan long aging runs around sessions where the pet stays out.
The highest base XP-per-second pets in the current meta, boosted by a mutation, age fastest. Check the Pet Tier List for the up-to-date ranking.
