How the OSRS XP Curve Works
Old School RuneScape uses a fixed experience formula that has never changed since the game's 2001 origins — every level requires roughly 1.104× the XP of the previous level, which is why the climb from 1–50 feels quick but 92–99 alone takes as much XP as every other level combined. Here's the exact XP total required at key checkpoints:
Level 1
0 XP
Level 10
1,154
Level 30
13,363
Level 50
101,333
Level 70
737,627
Level 92
6,517,253
Level 99
13,034,431
Notice level 92 sits at exactly half the total XP required for level 99 (6,517,253 × 2 = 13,034,431) — a well-known landmark OSRS players use to gauge "halfway to max" on any skill.
The Official Formula
XP(level) = ⌊ ¼ × Σ ⌊n + 300 × 2^(n/7)⌋ ⌋ for n = 1 to level−1
This calculator derives its entire level table directly from this formula rather than a hand-typed list, so every number above is provably exact — not an approximation.
How "Time to 99" Is Calculated
Once the XP gap between your current progress and your target level is known, the time estimate is straightforward division against your chosen method's XP/hr rate:
Formula
Hours Needed = (Target XP − Current XP) ÷ XP per Hour
Worked Example — Level 1 to 99 Magic via High Alchemy
(13,034,431 − 0) ÷ 70,000 ≈ 186 hours (≈ 93 days at 2 hours/day)
The GP cost or profit for the full grind is the hours needed multiplied by the method's GP/hr rate — a negative rate means you're spending Sheckles (usually on runes, bones, or raw materials), while a positive rate means the method pays for itself and then some, which is common for Slayer, Farming, and high-level Runecrafting methods.
Best XP/hr and GP/hr Methods by Skill
Some skills are pure cost (Magic, Prayer, Construction), some are pure profit (Runecrafting, Slayer, Hunter), and a few offer both a cheap and a fast option depending on your budget. Here's a snapshot of the top method per skill in this calculator:
| Skill | Fastest Method | XP/hr | GP/hr |
|---|---|---|---|
| Magic | Bursting/Barraging | 300,000 | −1,400,000 |
| Smithing | Dart Tips | 500,000 | −600,000 |
| Fletching | Dragon Darts | 500,000 | −60,000 |
| Runecrafting | Blood Runes | 22,000 | +1,200,000 |
| Hunter | Black Chinchompas | 275,000 | +200,000 |
| Mining | Blast Mining | 95,000 | +400,000 |
| Slayer | Konar Tasks | 40,000 | +300,000 |
Full details for all 23 skills — including budget-friendly alternatives at lower levels — are available in the Training Method dropdown above. GP/hr figures move with Grand Exchange prices, so treat them as directional rather than exact live quotes.
