Hey! I'm the solo dev behind EncounterForge 5e. I built this because D&D encounter math has always felt like something a calculator should just handle — DMG thresholds, monster count multipliers, XP breakdowns. I wanted something that shows you why an encounter is deadly, not just that it is. The core calculator is completely free, no account needed. Paid tiers unlock PDF export, session history, and DM tools like a Quest Journal and Module Rescaler. It's still in beta — I'm actively fixing bugs and adding features. Would love to hear what would make your prep easier!

Free D&D 5e encounter calculator — real-time XP math as you add monsters (beta, feedback welcome)

I'm more of a builder than a player I got into D&D tooling because the encounter math always looked like the most fixable problem. The DMG XP thresholds, the monster count multiplier, the back-and-forth... it felt like something a calculator should just handle.

So I built EncounterForge 5e.

Free, no account needed:

Real-time difficulty rating (Easy / Medium / Hard / Deadly) with full XP breakdown
168 SRD monsters, filterable by CR, type, HP, AC
Auto-Suggest picks monster combos to hit a target difficulty for your specific party (3x/day)
