Duty %

About this calculator

Use this calculator to get a PWM-style duty cycle from high time and low time. Enter on and off in the same time unit.

Duty % = 100 × on / (on + off). 2 on and 8 off is 20%. Average PWM voltage is that fraction times the supply. On plus off must be positive.

On: Time high.

Off: Time low.

Duty %: On as a percent of the period.
