Project weight in kg at Age 500, plan the XP needed, and share your pet’s growth scenario.
Patch-aware age limit
Age 500 is the current community-reported default. Match the cap shown in your game so an old patch limit does not distort the result.
Enter your pet’s current age and weight in kg. Choose any target age within your patch cap.
Add your current age and weight to see a projection, or try the labeled example.
Projected kg = current kg ÷ (current age + 10) × (target age + 10). Keep the same pet and modifiers. This community model estimates growth; it does not estimate Trade Tokens or prove a pet’s cooldown. Community Pets reference.
Cooldown by age
Example observations are prefilled below. Replace them with the same pet at two ages, keeping its mutation, toy, hunger, buffs and patch unchanged. The projection follows your observed trend.
Scenario target age
Age 145
Observed reduction
1s per age
Additional ages
35
At cap 500
15s or lower*
This target is reachable by age 145 only if the observed linear trend continues. *The real pet-specific cooldown floor is unknown.
This page answers how cooldown changes with age using two observations from one pet. It also keeps the weight projection close because age and weight are often checked together.
Use the ability calculator for buffs, multiple pet copies, fires per hour, and session totals.
Open the ability proc calculatorKeep the same pet, mutation, toy, hunger, active buffs, and game patch between observations.
Use ages far enough apart that the rounded displayed cooldown actually changes.
Convert minutes to seconds first. For example, 1m 20s becomes 80 seconds.
Pet-specific floors and non-linear scaling can break the trend, so replace old observations as you progress.
Legacy mechanic warning
The older community page says the machine required an Age 100+ pet, consumed a duplicate, and raised the former limit one age at a time up to 125. Newer June-July 2026 evidence shows pets reaching Age 500, and players report legacy age breaks becoming a head start when the cap changed.
Do not sacrifice a duplicate based only on an old guide. Inspect the current game UI and patch state first.
No official current formula page was found. The weight equation and two percent boundary come from the community-maintained wiki. Age 500 is supported by a maintained calculator and a June 2026 leveling guide. The old Age Break rules remain here only as historical context. The cooldown result uses your observations because a universal current formula is not supported.

Inspect sourceEnter its current age and weight in kg. The community model divides current weight by current age plus 10, then multiplies by 510 for Age 500. For example, 2 kg at Age 1 projects to about 92.73 kg at Age 500. This is a model example, not a guarantee for your pet or patch.
Yes. Share plan creates a link that restores the same age, kg and target. Save image downloads a result card. Plan XP carries both ages into the XP tool, where you enter your measured XP rate and daily hours.
Record the same pet at two different ages without changing its mutation, toy, hunger, buffs, or game patch. Enter both displayed cooldowns and a target. The calculator measures the observed seconds-per-age change and estimates when the target would be reached if that trend continues.
No. Cooldown scaling and floors are pet-specific and can change with modifiers and patches. The result is a scenario based on two observations from the same unchanged pet, not a universal formula.
Current June-July 2026 community reports and maintained calculators use an Age 500 cap. Older Age 100 and Age 125 pages still exist, so the calculator keeps the cap editable and asks you to follow the value shown in your current game patch.
The community-documented model is W2 = W1 / (A1 + 10) x (A2 + 10). It uses one observed weight and age to project a second age. The community wiki warns that limited measurement precision can produce about a two percent error.
Older sources describe a machine that raised the former Age 100 cap one level at a time to 125. The June 2026 Age 500 update made those old limits unreliable. Check the current in-game interface before sacrificing a duplicate pet or paying any legacy machine cost.
Keep the same pet specification as you move from age and cooldown into abilities, leveling, mutations, value, or trade decisions.
