OSRS DPS Calc
OSRS DPS Calc is a free, independent Old School RuneScape toolkit for comparing combat setups, planning upgrades, calculating skill requirements, and checking Grand Exchange information. Every important input is visible and editable, helping players understand why a result changes.
DPS Comparison
The main DPS calculator compares two Melee, Ranged, or Magic setups against the same target. Players can use Sand Crab, Giant Mole, and Vorkath presets or create a custom target with editable defence, hitpoints, and defence bonuses.
Each setup supports combat style, attack type, levels, equipment bonuses, prayers, attack-style bonus, attack speed, and estimated cost. Results include average DPS, maximum hit, hit chance, estimated time to kill, attack and defence rolls, DPS difference, and incremental DPS per million GP.
This helps players determine whether an expensive equipment upgrade provides meaningful improvement. It also demonstrates why a faster weapon can outperform a slower weapon with a larger maximum hit.
Additional Tools
The site includes calculators for combat level, melee max hit, Prayer, Construction, Herblore, Crafting, Cooking, and Fletching. Skill calculators convert current and target levels into required experience and whole action counts.
The Grand Exchange tracker provides recent OSRS Wiki price information, observed five-minute volume, tax reminders, and item timestamps. Supporting sections cover money-making methods, quests, gear, bosses, achievement diaries, Hiscores, XP planning, methodology, and sources.
How to Use
No account or installation is required. Choose a target, configure Setup A and Setup B, and review the comparison. Change one input at a time to see how levels, equipment, prayers, attack speed, and target defence affect the result.
The model uses standard OSRS attack-roll, defence-roll, hit-chance, average-damage, and attack-speed calculations. It also explains that special attacks, movement, phase downtime, immunities, and equipment-specific effects may require separate modelling.
OSRS DPS Calc is completely free and works in modern desktop and mobile browsers. It is an independent fan resource and is not affiliated with or endorsed by Jagex.
