OSRS Combat Calculator – Instantly Calculate Your RuneScape Combat Level

Introduction

That’s where our OSRS Combat Calculator at AizoroTools.com comes in. With just a few quick inputs—your attack, strength, defense, hitpoints, ranged, magic, and prayer levels—you can instantly calculate your precise combat level, whether you’re a pure, a main, or anything in between.

What Is Combat Level in OSRS?

Combat level is a numerical representation of your overall combat prowess in the game. It’s the number next to your character’s name and is calculated based on a combination of your:

• Attack

• Strength

• Defense

• Hitpoints

• Ranged

• Magic

• Prayer

The maximum combat level is 126 for melee-based accounts and 126.1 for ranged/magic-based accounts.

Your combat level determines:

• Who you can attack in the Wilderness

• What content you can access

• How you stack up in PvP worlds

• Your efficiency in PvM (Player vs Monster) combat

Why Use an OSRS Combat Calculator?

The formula for calculating combat level is not simple. It’s a weighted formula that changes depending on whether your combat style is melee, ranged, or magic. Doing it by hand is a pain.

Here’s why the calculator is useful:

✅ Instant Results – No more math
✅ Accurate to the decimal
✅ Helps optimize your build (pures, zerkers, tanks, etc.)
✅ PvP Planning – Know who you can fight
✅ Training Goals – See how much a level-up will affect your combat level

What Inputs Does It Take?

Just enter your current levels for the following stats. Each input accepts values from 0 to 99, except for Hitpoints, which must be 10 or more.

---

1. Attack Level (1–99)

Attack improves your accuracy with melee weapons. Essential for:

• Main accounts

• 60 Attack pures (Dragon scimitar, DDS)

• 75 Attack builds (Godswords)

---

2. Strength Level (0–99)

Strength boosts melee max hit. Often maxed early by:

• 1 Defense pures

• Obby maulers

• Max mains

---

3. Defense Level (0–99)

Defense reduces the chance of being hit and allows better armor. Important for:

• Mains

• Tanks

• Zerker pures (usually capped at 45)

4. Hitpoints Level (10–99)

Gained through combat training. Minimum value is 10. Higher HP means longer fights and more survivability.

5. Ranged Level (0–99)

Increases accuracy and max hit with bows, crossbows, and other ranged weapons. Pure builds often rely heavily on range.

---

6. Magic Level (0–99)

Boosts spell power and accuracy. Also affects access to teleportation and PvM spells. Used heavily in:

• Mage pures

• Void builds

• PvM mains
