About Us

CombatCalculatorOSRS.com is a fan-made toolkit for Old School RuneScape players who want quick, clear answers to a common question: “What’s my combat level—and what’s the fastest way to reach the next one?”

We built this site to feel lightweight and practical: enter your stats (or import public HiScores), see your combat level with precision, identify your dominant combat style, and get simple “next level” suggestions that show which single stat upgrade gets you there fastest. There’s also an optional Hitpoints estimation mode for niche training paths where HP XP doesn’t always track evenly.

What we care about

• OSRS-accurate math. We follow the standard combat formula and rounding behaviors so the results line up with what the game displays.
• Privacy by default. No accounts, no passwords, no weird data grabs. Use the calculator anonymously if you want.
• Fast and readable. Clean UI, quick inputs, instant results—built for desktop and mobile.
• Helpful, not spammy. We don’t want to be “another noisy tool site.” The goal is clarity.
