If you play Old School RuneScape (OSRS), you’ve probably heard people talk about “DPS calculators.” DPS means damage per second, and these tools help you figure out which weapon, gear, or setup gives you the highest consistent damage output. They’ve become essential for PvMers, speedrunners, and anyone who wants to squeeze the most value from their equipment.
But with multiple calculators available—Wiki, GearScape, OldSchool.tools, spreadsheets, even RuneLite plugins—the obvious question is: which one is the best?
What Makes a Good DPS Calculator?
Before ranking them, it’s worth noting what actually matters when comparing calculators:
- Accuracy – Uses correct formulas for max hit, accuracy, and DPS.
- Ease of use – Clear UI, quick inputs, mobile-friendly.
- Support for combat styles – Melee, Ranged, Magic.
- Boss-specific flexibility – Handling multi-phase fights or special mechanics.
- Community trust – Updated regularly, transparent about methods.
The Top OSRS DPS Calculators
1. OSRS Wiki DPS Calculator
The Wiki DPS calculator is the community’s go-to tool. It’s clean, reliable, and always updated alongside game patches. You can plug in gear, prayers, and potions, then share your loadouts with a link. It’s also one of the easiest to use.
👉 Best for: General use, beginners, and anyone who wants accuracy without overthinking.
2. GearScape
GearScape is a powerhouse for comparing multiple setups. It lets you filter out items you don’t own, set budget constraints, and test different scenarios like multi-phase bosses. If you’re trying to decide between two weapons or optimize your boss loadout, GearScape often gives more flexibility than the Wiki tool.
👉 Best for: Advanced players and bossing optimization.
3. OldSchool.tools DPS Calculator
This is a straightforward option. OldSchool.tools strips everything down to the basics—pick your gear, check DPS, done. It covers melee, ranged, and magic but without all the extra features.
👉 Best for: Quick checks and players who don’t need extra bells and whistles.
4. OSRSBox DPS Guide
Back in 2019, OSRSBox published an in-depth blog on how DPS is actually calculated. It’s not an interactive tool, but it’s the best explanation of the math behind accuracy rolls and damage. If you’re curious why DPS calculators give the results they do, this guide is worth a read.
👉 Best for: Players who want to understand the formulas behind the numbers.
5. RuneLite DPS Plugin (Legacy)
There used to be a RuneLite DPS meter plugin, which displayed damage rates in real time. While it’s no longer supported officially, some players still seek it out. It’s more of a live tracker than a calculator, but historically it was helpful for seeing how gear changes impacted DPS during a fight.
👉 Best for: Players who prefer in-game feedback over external tools.

Which DPS Calculator Should You Use?
- If you’re new to DPS calculators → Use the OSRS Wiki tool.
- If you’re optimizing for raids or bosses → Choose GearScape.
- If you just need something quick → Go with OldSchool.tools.
- If you want to learn the math → Read the OSRSBox blog.
Most players end up using both the Wiki tool (for trust & sharing) and GearScape (for fine-tuning setups) depending on the situation.
How DPS Is Calculated (Simple Breakdown)
Every calculator works off the same three principles:
- Max Hit – Your highest possible hit based on strength, gear, and boosts.
- Accuracy – The probability your hit will land against an enemy’s defence.
- DPS – Max hit × accuracy × attack speed.
Different tools just present this data in different ways.
