What XP formula does this use?

It uses Jagex's exact experience curve: xp(L) = floor((1/4) × Σ floor(n + 300 × 2^(n/7))). This gives 13,034,431 XP for level 99 and about 104,273,167 XP for level 120.

Why does level 99 to 120 take so much longer than 1 to 99?

The XP curve is exponential. Reaching level 99 needs about 13 million XP, but level 120 needs over 104 million — so the last 21 levels require roughly seven times the XP of the first 98.

How accurate is the time estimate?

The XP totals are exact. The time depends on your chosen XP-per-hour rate, which varies with gear, location, and how consistently you play. Pick the band closest to your real rate for the best estimate.

Can I use this for the 200M XP cap?

This tool forecasts to level 120. Since 200M XP is far beyond level 120, you can estimate the remaining time by dividing the extra XP by your XP-per-hour rate.

Does this run online?

No. The XP table is computed and all maths runs locally in your browser. Nothing is sent to a server.

Know exactly how long the grind will take

RuneScape 3 levelling rewards consistency, but the XP curve hides just how much work the higher levels demand. This calculator uses Jagex’s exact experience formula to tell you the XP remaining to your target, then converts it into training hours and real-world days based on your method and daily play time.

How it works

Total XP to reach a level follows the published Jagex curve:

xp(L) = floor( (1/4) * SUM_{n=1}^{L-1} floor( n + 300 * 2^(n/7) ) )

Level 1 is 0 XP, level 99 is 13,034,431 XP, and level 120 is about 104,273,167 XP. The tool computes the XP for both your current and target levels, subtracts to get the XP remaining, and divides by your chosen XP-per-hour rate to get total training hours. Dividing again by your hours per day gives the number of days.

Example and tips

Going from level 70 to 99 with a standard 250k XP/hour method needs roughly 12.7 million XP, or about 51 hours — around 17 days at 3 hours a day. Push to an efficient 500k XP/hour method and the same goal halves to about 25 hours. The single biggest lever is your XP-per-hour rate, so investing in better gear or a faster method usually beats simply playing longer. Re-run the tool whenever your rate improves to keep the forecast honest.
