Duty Cycle Calculator

Find the duty cycle of a signal.

Duty cycle (%) 20

Formula: duty cycle = on time ÷ period × 100

Step-by-step with your numbers:

1. Values used:

2. On time = 2

3. Period = 10

5. Duty cycle = On time x Period = 2 x 10 = 20%

Did we solve your problem today?

Duty cycle is the fraction of one period a signal is active.

The math behind it

duty cycle = on time ÷ total period × 100.

2 ms on, 10 ms period → 20%.

PWM?

Pulse-width modulation varies duty cycle to control power (e.g. LED brightness, motors).
