This gear ratio calculator determines the rate of mechanical advantage or disadvantage a gear train produces in a gear system. Read on to learn more about gear ratio and its importance in …

Use our Gear Ratio Calculator to optimize your vehicle's performance by accurately determining gear ratios, RPM, tire diameter, and MPH.

Save yourself the headache and let us figure out your ring-and-pinion gear ratio! Just type in your info (example: 5000 RPM), press calculate, and you’ll get the right ratio without the guesswork.

Quickly estimate overall gear reduction, output speed (RPM), and output torque for single- or multi-stage gear trains. Enter tooth counts or a known ratio for each stage, set efficiency, and …

Gear Ratio = Output Gear Teeth ÷ Input Gear Teeth. Say your motor drives a 20-tooth gear that meshes with an 80-tooth gear. That's 80 ÷ 20 = 4:1. Your motor spins four times for every …
