What are experience groups?

Each Pokémon species belongs to one of six experience groups that set how much total XP each level requires. Fast group Pokémon reach level 100 with 800,000 XP, while Slow group ones need 1,250,000, so the group strongly affects grind time.

What XP formula does this use?

It uses the official cubic-based formulas for each group. For example, the Medium Fast group requires n cubed total XP at level n, and the Fast group requires 0.8 times n cubed, matching the in-game tables exactly.

How is the time estimate produced?

It subtracts the XP for your current level from the XP for the target level to get XP remaining, then divides by your daily XP gain (XP per hour times hours per day) to get the number of days.

Why does my real grind feel slower than the estimate?

XP per hour usually drops as enemies become lower level relative to you, and breaks, travel, and menus eat real time. Treat the estimate as a best case and pad it if your hourly rate fades over a session.

Does an XP boost like the Lucky Egg change the result?

Yes. A Lucky Egg roughly multiplies XP gain by 1.5. Bake that into your XP-per-hour figure before entering it, and the day forecast shrinks accordingly.

Reaching the Pokémon level cap is a grind whose length depends on your species’ experience group and your daily play. This calculator uses the real cubic XP curves to compute exactly how much experience you have left and forecasts the days and hours it will take at your pace.

How it works

Each experience group defines the total XP needed at a given level n. The common groups use these formulas:

Fast        : floor( 0.8 × n³ )
Medium Fast : n³
Medium Slow : floor( 1.2·n³ − 15·n² + 100·n − 140 )
Slow        : floor( 1.25 × n³ )

The XP remaining is the target level’s total minus the current level’s total. Dividing by your daily XP gain gives the day estimate:

xpRemaining = total(target) − total(current)
dailyXp     = xpPerHour × hoursPerDay
days        = xpRemaining / dailyXp

Example and tips

A Medium Fast Pokémon going from level 50 to 100 needs 100³ − 50³ = 875,000 XP. At 60,000 XP per hour for 2 hours a day that is 120,000 XP daily, or about 7.3 days. A Slow group Pokémon over the same range needs nearly 1.1 million XP and takes proportionally longer. Apply a Lucky Egg by raising your XP-per-hour figure by 50 percent before entering it, and remember real hourly rates drop as you outlevel your grinding spot.
