Fictional worked example

Compare television picture modes

A household keeps the same evening viewing schedule but measures different average draw with two picture modes using the same program.

Inputs and calculation

Cinema mode
Tool input	Value
Currency	USD
Power unit	W
Power	95
Hours per day	3
Days or equivalent sessions	30
Duty cycle (%)	100
Energy price (USD per input kWh)	0.24

95 ÷ 1,000 × 3 × 30 × 100% = 8.55 kWh. 8.55 × 0.24 rounds to USD 2.05.

Tool result · USD 2.05

Bright mode
Tool input	Value
Currency	USD
Power unit	W
Power	140
Hours per day	3
Days or equivalent sessions	30
Duty cycle (%)	100
Energy price (USD per input kWh)	0.24

140 ÷ 1,000 × 3 × 30 × 100% = 12.6 kWh. 12.6 × 0.24 rounds to USD 3.02.

Tool result · USD 3.02

At identical viewing time the brighter mode adds 4.05 kWh. This isolates the power difference from the effect of watching longer.

Treat these as example measurements. Content, brightness and connected speakers can change measured draw.
