What is the XP formula in Old School RuneScape?

OSRS uses a fixed cumulative table. The XP required for level L is floor(sum from n=1 to L-1 of floor(n + 300 * 2^(n/7)) / 4). Level 99 requires 13,034,431 XP and level 92 is exactly the halfway point at 6,517,253 XP.

How much XP is needed for level 99?

Exactly 13,034,431 experience. Reaching level 92 (6,517,253 XP) means you are halfway to 99 in raw experience, which is why pushing the last few levels feels so slow.

What are virtual levels?

The XP table continues past level 99 up to a theoretical level 126 at 200,000,000 XP (the experience cap). These virtual levels are cosmetic and shown in some interfaces but do not unlock new content.

Why does each level need more XP than the last?

The formula grows roughly geometrically because of the 2^(n/7) term, so the XP per level keeps increasing. Early levels take seconds while the jump from 98 to 99 alone is over 1.2 million XP.

Does this match the in-game numbers exactly?

Yes. The calculator uses the same integer floor-based formula Jagex uses, so every level threshold matches the official OSRS experience table to the exact XP.

The Old School RuneScape XP & Level Calculator turns a raw experience number into your current level and tells you exactly how much grinding remains until your next level or any target up to 99 (and virtual 126). It uses the same integer formula the game itself uses, so the thresholds match the official hiscores precisely.

How it works

OSRS experience is defined by a single cumulative formula. The experience required to reach level L is:

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

To find your level from total XP, the calculator walks the table and returns the highest level whose threshold you have met or exceeded. The XP to the next level is simply XP(currentLevel + 1) - yourXP, and the XP to a target level is XP(target) - yourXP (clamped to zero if you are already there).

Key milestones

Level 92 = 6,517,253 XP — the exact halfway point to 99.
Level 99 = 13,034,431 XP — the standard “maxed” skill.
Level 126 = 200,000,000 XP — the experience cap (virtual level).

Because of the 2^(n/7) growth, each level costs noticeably more than the last. The single jump from 98 to 99 is over 1.2 million XP, more than every level from 1 to 74 combined.
