What XP curve does the calculator use?

It uses a cubic curve where the total XP to reach a level equals the level cubed, similar to the medium-fast growth in many RPGs. The XP for a single level is the difference between consecutive cubes, so higher levels cost far more than early ones.

Why does the final stretch take so long?

Because XP scales with the cube of the level, the gap between level 99 and 100 is enormous compared with the gap between level 9 and 10. The last handful of levels can take as long as everything before them combined.

How accurate is the XP-per-hour estimate?

The built-in methods are reasonable averages, but real rates vary by location, gear and efficiency. For the most accurate forecast, time yourself for an hour, note the XP gained, and enter it as a custom XP-per-hour rate.

How is the finish date computed?

The tool divides total play hours by your hours-per-day to get whole days, then adds that many days to today. It assumes you play your stated hours every day; skipping days pushes the date back proportionally.

Can I model an XP boost?

Yes. Either pick the boost method preset or enter a custom XP-per-hour that reflects your active multiplier. The remaining-time math scales directly with the rate, so doubling XP-per-hour roughly halves the days needed.

Grinding to a level cap is mostly arithmetic once you know your XP rate, but the cubic XP curve makes the back half deceptively long. This calculator turns your level, play schedule and method into a realistic day-count and finish date so you can plan the grind instead of guessing.

How it works

Total XP to reach a level follows a cubic curve, and the remaining grind is the difference between the cap and your current level:

totalXp(L)   = L^3
xpRemaining  = totalXp(cap) − totalXp(current)
hoursNeeded  = xpRemaining / xpPerHour
days         = ceil(hoursNeeded / hoursPerDay)

Because XP grows with the cube of the level, each level costs more than the last and the final levels dominate the timeline.

Example and tips

From level 30 to 100 at 30,000 XP per hour and 2 hours per day, the remaining XP is roughly one million, around 33 play hours, and about 17 days. Time a single hour of your actual grind and enter it as a custom rate for the sharpest estimate, and remember that an XP boost scales the whole timeline down in direct proportion.
