OSRS DPS Calc
OSRS DPS Calc is a free, independent web-based damage-per-second calculator for Old School RuneScape that compares two combat setups against the same target, outputting hit chance, average DPS, and time to kill for Melee, Ranged, and Magic.
What is OSRS DPS Calc?
OSRS DPS Calc is a free, web-based OSRS damage calculator published by the LootPath editorial team. You input two loadouts — each with attack roll, max hit, and attack speed — plus one shared target with Hitpoints and a defence roll. It returns hit chance, average damage per second, estimated time to kill, and (if setup cost is entered) incremental DPS per 1M GP. It runs entirely in the browser, requires no login, and never asks for a Jagex password or Bank PIN. Open OSRS DPS Calc to start comparing.
Key Features
- Two-loadout comparison — Enter Loadout A and Loadout B against the same target to see hit-chance difference, DPS, TTK, and cost side by side.
- Visible DPS formula — The estimate uses hit chance × average hit ÷ attack interval, with attack speed converted from OSRS 0.6-second game ticks into seconds per attack.
- Target-aware accuracy — Hit chance is calculated by comparing your attack roll with the target defence roll, so the same gear can perform differently against low- vs high-defence monsters.
- Style coverage — Supports Melee, Ranged, and Magic, and accounts for slash, stab, crush, Ranged, and Magic defence.
- Upgrade value — Optional setup cost adds cost per DPS and incremental DPS per 1M GP to show whether a pricier loadout is worth the GP.
- No account connection — Works without a login; no Jagex password, Bank PIN, or game session token is ever collected.
Who should use OSRS DPS Calc?
- Players planning gear upgrades — Compare two setups against the same target to see whether a more expensive weapon actually improves DPS before spending GP.
- Boss preppers — Check whether your current gear hits reliably against a boss's defence roll, and whether switching attack style (slash, stab, crush, etc.) wins.
- Efficient skillers — Test questions like "faster weapon vs bigger max hit" for training setups.
What can you do with OSRS DPS Calc?
- Compare weapon speed vs max hit — See whether a faster weapon with lower max hit outperforms a slower, harder-hitting one against a specific target.
- Evaluate accuracy vs defence — Input a high-defence target to see if an accuracy-focused setup narrows the gap against a max-hit setup.
- Check upgrade value — Add setup prices to get cost per DPS and incremental DPS per 1M GP, so you know what each million GP actually buys.
- Plan a boss kill — Estimate time to kill for two loadouts to decide if a gear change reduces fight time enough to matter.
How does OSRS DPS Calc work?
- Set one target — Enter Hitpoints and the relevant defence roll so both loadouts face the same monster.
- Enter two combat setups — Add attack roll, max hit, attack speed, and optional setup cost for Melee, Ranged, or Magic.
- Compare DPS and TTK — Read hit chance, average DPS, estimated time to kill, and the gain delivered by the more expensive setup.
The calculator uses the standard OSRS damage formula referenced from the OSRS Wiki and clearly states what it does not model: special attacks, boss phases, damage caps, and target-specific mechanics.
FAQ
What does OSRS DPS mean?
OSRS DPS means average damage per second. For a standard attack, the estimate combines hit chance, average damage on a successful attack, and the weapon's attack interval in seconds.
Does OSRS DPS Calc model every special attack and boss phase?
No. The current tool is a transparent standard-attack comparison. Special attacks, damage caps, immunities, phase downtime, and weapon-specific effects must be checked separately.
Is OSRS DPS Calc an official Jagex product?
No. OSRS DPS Calc is an independent fan-made toolkit published by LootPath and is not endorsed by or affiliated with Jagex.
Do I need to connect my RuneScape account?
No. The DPS calculator and supporting OSRS tools work without a login and never require a Jagex password, Bank PIN, or game session token.
