Track your pet's age progression — from Age 1 to Age 100 — and calculate exactly how long it takes to level up using any farming method. XP rates sourced from the GAG Fandom Wiki with weight-based formulas.

Select which XP-boosting pets are in your team and enter their weights. The planner uses weight-based formulas from the GAG Fandom Wiki to calculate your combined XP per second (adjusted by hunger). Self-only pets boost only themselves; Team pets boost all active pets.
All XP rates sourced from the GAG Fandom Wiki. Weight-dependent formulas mean heavier pets generate more XP. Capybara also prevents hunger loss for nearby pets. Starfish gains XP even at 0 hunger.
Leveling a pet in Grow a Garden is one of the biggest time investments you can make in the game. A single pet leveled from Age 1 to Age 50 requires 868,305 XP and roughly 160 hours of passive farming with a Blood Owl — or less than 40 hours if you know how to stack your methods correctly. This calculator gives you the exact time estimate based on your pet, your setup, and your schedule. No guessing. No wasted farming sessions.
Use the Pet Leveling Calculator above to get your time estimate. Then read the guide below to understand the system, maximize your XP rate, and never waste a farming session again.
In Grow a Garden, pets do not level up through a traditional point system. Instead, they age. Every pet starts at Age 1 and progresses through a continuous XP curve toward Age 100. Players often call this "leveling" because the effect is identical — higher age means stronger abilities, better passive generation, and more value in trades — but the mechanic is aging, not leveling.
XP is earned passively by keeping a pet equipped and actively by farming crops, triggering events, and using helper pets that accelerate the rate. The hunger bar is the single most important variable most players ignore — when hunger reaches 0%, XP generation stops completely.
The XP required to advance from Age n to Age n+1 follows this community-verified formula:
This exponential curve is why the early ages feel fast and the late ages feel brutal. Age 1 to Age 10 costs approximately 1,917 XP total. Age 40 to Age 50 costs roughly 224,000 XP — more than the entire first 40 ages combined.
Rarity does NOT change how much XP a pet needs. Every pet — Common or Prismatic — follows the same floor(20 × n2.02) formula. Rarity affects how much XP-per-second the pet generates, not how much it costs to level.
Every pet has a hunger bar that depletes over time. When hunger reaches 0%, XP generation pauses entirely. This single mechanic is responsible for more wasted farming time than any other factor in the game.
💡 Pro Tip: Feed your pet before every AFK session. This single habit can reduce your total leveling time by 15–25% across a full session.
The table below shows the cumulative XP needed to reach each major age milestone, plus the estimated farming time using two common methods: Blood Owl (0.08 × Weight + 0.5 XP/sec, ~1.3 XP/sec at 10kg) and a standard Owl (~0.20 XP/sec + 0.01/age). Use this to plan your leveling sessions and set realistic targets before committing.
| Age Target | XP This Age | Cumulative XP | Blood Owl Time | Owl Time |
|---|---|---|---|---|
| Age 5 | 328 XP | 612 XP | 8m | 41m |
| Age 10 | 1,692 XP | 5,918 XP | 1h 16m | 5h 29m |
| Age 15 | 4,132 XP | 21,265 XP | 4h 33m | 16h 53m |
| Age 20 | 7,657 XP | 52,064 XP | 11h 7m | 36h 9m |
| Age 25 | 12,275 XP | 103,766 XP | 22h 10m | 64h 3m |
| Age 30 | 17,991 XP | 181,851 XP | 38h 51m | 101h 2m |
| Age 35 | 24,809 XP | 291,819 XP | 62h 21m | 147h 23m |
| Age 40 | 32,732 XP | 439,190 XP | 93h 51m | 203h 20m |
| Age 45 | 41,764 XP | 629,503 XP | 134h 31m | 269h 1m |
| Age 50 | 51,907 XP | 868,305 XP | 185h 32m | 344h 34m |
| Age 60 | 75,535 XP | 1,513,645 XP | 323h 26m | 525h 34m |
| Age 75 | 119,365 XP | 2,984,761 XP | 637h 46m | 872h 44m |
| Age 100 | 214,888 XP | 7,152,114 XP | 1528h 14m | 1655h 35m |
Notice the jump from Age 50 (868,305 XP) to Age 100 (7,152,114 XP) — that is a 7.24× increase for diminishing returns on most pets. Only push beyond Age 50 for pets with strongly scaling abilities.
Blood Owl rate: (0.08 × Weight + 0.5) XP/sec, ~1.3 XP/sec at 10kg (full hunger). Owl rate: ~0.20 XP/sec + 0.01/age (full hunger). Actual time will vary based on weight, hunger management and active farming sessions. Formula: floor(20 × n2.02), community verified June 2026.
Every competitor calculator tells you how long it takes to max your pet. None of them tell you whether you should. That distinction matters — because spending 160 hours leveling a Common Cat is an objectively worse investment than spending 80 of those hours on a Blood Owl.
Before you commit to a full leveling run, run your pet through this decision framework.
Max these pets first, every time, no debate:
Look at the XP table above. Age 1 to Age 25 costs approximately 103,766 XP — about 1.5% of what Age 100 costs. But you capture roughly 40% of the practical farming benefit of a maxed pet in that first 25 ages for most pets. This is the budget player's optimal stopping point.
For pets you plan to trade within the next two weeks, Age 25 to Age 30 is where the value-per-XP ratio is highest. You've invested enough XP to show commitment and get a level premium in trades, without sinking 870,000+ XP into a pet you're giving away.
Some pets have static abilities that do not scale with age, or scale so minimally that the 868,305 XP investment from Age 1 to Age 50 will never be recouped in value. For these pets, Age 10 to Age 20 is plenty:
The difference between a player who reaches Age 50 in 60 hours and one who takes 180 hours is almost entirely method selection and execution, not time played. Here are all the farming methods your calculator supports, ranked by XP-per-hour output.
These pets generate XP continuously for your active pet as long as they have hunger. Stack as many as possible.
These methods require your attention but deliver significantly higher XP rates than passive pets alone. Combine them with passive helpers for maximum output.
Blood Moon is the single highest XP-per-hour event in the game at 18,000 XP/hour — more than 3× the rate of a Blood Owl passive. The problem is that most players simply wait for it to end. Here is exactly what to do the moment Blood Moon activates:
🔥 A single fully-active Blood Moon session of 45 minutes can deliver approximately 13,500 XP — equivalent to roughly 2.5 hours of passive Blood Owl farming. Blood Moon sessions, done correctly, are the single best ROI of any time you spend in the game.
The Stork pet delivers fruit to another player's garden and in doing so generates XP for your active pet. Players discovered that running a second account while your main is AFK creates a continuous XP delivery loop:
This method is particularly effective for early-game players who do not yet have a Blood Owl or multiple Owls. It is community-discovered, not officially documented, and may change with future patches — verify it is still active before building your strategy around it.
Every guide tells you that active farming is faster. None of them show you by exactly how much, or help you decide which approach fits your schedule. Here is the honest comparison for reaching Age 50 (868,305 XP total):
Pure AFK leveling to Age 50 takes approximately 186 hours. Active event farming cuts that to 40 hours. The difference is not skill — it is method selection and event timing. Use the calculator to plan around your schedule.
No other pet leveling guide covers this topic. It is the question traders ask every day in the Grow a Garden community: "Is it worth maxing this pet before I trade it?" Here is the framework to answer that question for any pet.
When you sell or trade a pet, its age directly affects perceived value and offer quality. The reason is simple: the buyer is paying partly for the pet's current ability output and partly for the farming time you have already invested. A higher-age pet means less work for the buyer.
The age premium is largest for pets whose abilities scale visibly with level — Dragonfly, Blood Owl, Kitsune, Queen Bee. It is smallest for pets whose abilities are static or cosmetic.
Use the Trade Calculator (linked in the Related Tools section below) to compare your pet's current trade value before and after committing to a full leveling run. The numbers will tell you whether the 160+ hours is worth it before you start.
The calculator at the top of this page gives you a precise time estimate based on your exact starting age, target age, and chosen farming method. Here is how to get the most accurate result:
💡 Pro Tip — Use the Hunger Adjustment: Most players leave hunger at 100% and get an overly optimistic estimate. Set it to 75–80% for AFK sessions without a Capybara. The difference between 80% and 100% hunger is the difference between a 60-hour estimate and a 48-hour estimate — plan honestly.
