Choosing the right weapon in Old School RuneScape isn’t just about raw stats. Attack speed, bonuses, and hit chance all shape your true damage output. The OSRS weapon damage calculator helps you see exactly how much DPS (damage per second) your setup delivers.
By entering your stats, gear, and boosts, you can quickly compare weapons, plan Slayer tasks, or prepare for PvP and boss fights. This guide walks you through each step so you can make the most of the calculator and maximize your combat efficiency.
Why a Weapon Damage Calculator Matters in OSRS
Every hit in Old School RuneScape depends on stats, weapon speed, and accuracy. Even high Strength levels won’t guarantee good DPS if you’re using the wrong setup.
That’s where the OSRS weapon damage calculator helps—it shows your max hit, damage per second, and hit chance in seconds so you can optimize for Slayer, bossing, or PvP. For details about how we test formulas, visit the Methodology page for transparent insights.
Step 1: Enter Your Player Stats
Fill in your Attack and Strength levels. If you’re using ranged or magic, enter those skills instead.
👉 Space combat fans can measure weapon output in the Star Citizen DPS Calculator tool.
Step 2: Add Your Bonuses
Include all gear modifiers:
- Strength and accuracy bonuses from equipment.
- Prayer boosts like Piety or Rigour.
- Potion boosts such as Super Strength or Super Attack.
For advanced setups, you may also test modifiers in the OSRS attack speed calculator.
Step 3: Choose Your Weapon
Select the weapon you want to test. The calculator adjusts for:
- Attack speed (measured in ticks, 0.6 seconds each).
- Weapon type (melee, ranged, or magic).
- Special multipliers when applicable.
Players experimenting with spec weapons should also look at the special attack DPS calculator.
Step 4: Run the Calculation
Once inputs are ready, click calculate. You’ll see:
- Max hit – strongest possible hit.
- Average DPS – damage per second.
- Hit chance – how often your hits connect.
Step 5: Compare Setups in Real Scenarios
Test gear changes like:
- Whip vs. Tentacle on Abyssal demons.
- Blowpipe vs. crossbow for ranged DPS.
- Godsword specials in PvP.
| Setup | Max Hit | DPS | Hit Chance |
|---|---|---|---|
| Whip + Piety | 34 | 10.2 | 72% |
| Tentacle + Piety | 36 | 11.4 | 74% |
For bosses, you might want the OSRS boss DPS calculator to see how these numbers scale against high-defence enemies. Use the OSRS DPS Calculator to determine which weapon gives you the best time-to-kill ratio.
Common Questions Players Ask
Why does my DPS drop when I use faster weapons?
Because accuracy and strength bonuses matter more than speed alone.

Yes, but factor in protection prayers and food.
What’s a tick in OSRS?
One tick equals 0.6 seconds—every weapon is tied to a tick rate.
