OSRS DPS Formula

The core formula used for calculating theoretical DPS is: $$ \text{DPS} = \frac{(\text{Max Hit} + 1)}{2} \times \frac{\text{Hit Chance}}{100} \times \frac{1}{\text{Attack Speed (ticks)} \times 0.6} $$

Variables

• Maximum Hit ($M$): The highest damage value your current gear setup can roll. This includes potions, prayers, and special attack bonuses.
• Hit Chance (Accuracy %) ($H$): The probability (from 0 to 100) that your attack will successfully land against your target’s defence, derived from accuracy rolls.
• Attack Speed (Game Ticks) ($T$): The speed of your weapon or spell, where 1 tick equals 0.6 seconds. This is typically 4 ticks (2.4s) for most fast weapons, or 5-8 for slower ones.

What is Damage Per Second in OSRS?

Damage Per Second (DPS) is the metric used to measure the rate at which a player deals damage in Old School RuneScape. It is arguably the single most important metric for efficiency in all forms of combat, from training Slayer to bossing at the Theatre of Blood. A higher DPS means less time fighting and fewer supplies used.

The calculation is complex in reality, relying on hidden variables like the player’s Attack/Strength/Magic/Range bonuses, the opponent’s Defence, and the specific mechanics of the weapon being used. However, this calculator simplifies the process by requiring the three core outputs of any full DPS calculation: Max Hit, Hit Chance, and Attack Speed (in ticks).

How to Calculate OSRS DPS (Example)

1. Determine Max Hit ($M$): Assume a setup giving a Max Hit of 50.
2. Determine Hit Chance ($H$): Calculate the accuracy roll, resulting in a 90% Hit Chance.
3. Determine Attack Speed ($T$): The weapon is a Dragon Scimitar, which has a speed of 4 ticks.
4. Calculate Average Damage per Hit: Average Damage = $(50 + 1) / 2 = 25.5$.
5. Factor in Accuracy: Accurate Average Damage = $25.5 \times (90 / 100) = 22.95$.
6. Calculate Attacks Per Second: Seconds per Attack = $4 \times 0.6 = 2.4$ seconds. Attacks Per Second = $1 / 2.4 \approx 0.4167$ APS.
7. Final DPS: $22.95 \times 0.4167 \approx 9.56 \text{ DPS}$.

Frequently Asked Questions (FAQ)

Why is the calculated DPS sometimes higher than my expected in-game damage?

This calculator provides a theoretical maximum DPS. Real-world DPS can be lower due to opponent health remaining, walking/movement delays, or specific combat mechanics not accounted for in the simplified formula.

What is a ‘Tick’ in OSRS?

A tick is the fundamental unit of time in Old School RuneScape, lasting exactly 0.6 seconds. All game actions, from movement to combat, are measured in ticks.

How do I find my Max Hit and Hit Chance values?

These values require a separate Max Hit calculator (often found online) that inputs your exact gear, stats, and opponent’s defence to provide the final Max Hit and Accuracy roll probability.

Does this calculator work for all combat styles?

Yes. The simplified formula works for Melee, Ranged, and Magic, provided you have correctly determined the Max Hit and Hit Chance values for that specific style and target.
