Screen Time Cost Calculator

Calculate the true cost of your screen time, including device depreciation, electricity consumption, and potential health-related expenses. This calculator helps you understand both the financial and wellness impact of your digital device usage.

How It Works

The calculator uses these formulas to estimate various costs:

$\text{Electricity Cost} = \text{Hours} \times \text{Power Usage} \times \text{Electricity Rate}$

$\text{Device Depreciation} = \frac{\text{Device Cost}}{\text{Expected Lifespan}} \times \frac{\text{Daily Usage}}{\text{Total Daily Hours}}$

$\text{Health Impact Cost} = \text{Base Health Cost} \times \text{Usage Factor} \times \text{Risk Multiplier}$

Where:

• Hours = Daily screen time hours
• Power Usage = Device power consumption in kWh
• Electricity Rate = Cost per kWh
• Device Cost = Purchase price of devices
• Expected Lifespan = Device lifetime in years
• Usage Factor = Screen time relative to recommended limits
• Risk Multiplier = Based on usage patterns and preventive measures
