The OSRS Combat Level Calculator is a tool designed for Old School RuneScape players to determine their combat level based on their skill levels in Attack, Strength, Defence, Hitpoints, Prayer, Ranged, and Magic. The combat level is a key indicator of a player’s or monster’s strength in combat, calculated using a formula that balances melee, ranged, and magic-based skills. This calculator provides an accurate and instant result, helping players plan their training and optimise their combat builds. It is inspired by tools like the one found on oldschool.tools, offering a user-friendly interface that works across all screen sizes.

How to Use

1. Enter Skill Levels: Input your current levels for Attack, Strength, Defence, Hitpoints, Prayer, Ranged, and Magic in the provided fields. Ensure the values are between 1 and 99 (10–99 for Hitpoints).

2. Validate Inputs: The calculator will highlight any invalid entries (e.g., values outside the allowed range) with a red border.

3. Calculate: Click the “Calculate” button to compute your combat level.

4. View Result: Your combat level will be displayed instantly below the form. If the inputs are invalid, an error message will appear.

5. Experiment: Adjust skill levels to see how they affect your combat level, useful for planning skill training or creating specialized accounts like pures or skillers.

Tips

• Optimise Builds: For specific account types (e.g., 1 Defence pures), keep Defence at 1 and focus on Attack, Strength, Ranged, or Magic to minimise combat level while maximising damage output.

• Prayer Impact: Prayer has a smaller impact on combat level (divided by 2 in the formula), so levelling it is efficient for combat bonuses without significantly raising your combat level.

• Ranged/Magic Focus: If Ranged or Magic is much higher than Attack and Strength, the calculator uses the higher of the two for the final computation, ideal for ranged or magic-based builds.
