D&D 5e Encounter Calculator - DnD Metrics

Calculate encounter difficulty for Dungeons & Dragons 5th Edition using Challenge Ratings 2.0. Our D&D encounter calculator uses data from over 15,000 real combat encounters to predict battle difficulty with 87% accuracy.

Features of Our D&D Encounter Builder

How to Use the Encounter Calculator

  1. Add your party members with their levels
  2. Select monsters to face the party
  3. View difficulty rating and combat predictions
  4. Adjust encounter balance as needed

Why Use DnD Metrics?

Unlike the basic Challenge Rating system in the Dungeon Master's Guide, our calculator uses Challenge Ratings 2.0 - a data-driven system based on thousands of real D&D combats. This provides more accurate difficulty predictions for modern 5e gameplay.

Better Than Kobold Fight Club

DnD Metrics offers a modern alternative to Kobold Fight Club with improved accuracy, updated monster stats, and AI-powered combat predictions.
