Example: Cost Savings and ROI Calculation for LED Lighting Upgrade

A homeowner decides to replace all 20 incandescent bulbs with LED bulbs. Each incandescent bulb has a wattage of 60W, and the LED replacement is 8W, both providing similar lumens (brightness).


  • The average cost of electricity is $0.12 per kWh.
  • Each bulb operates for an average of 5 hours per day.
  • Each LED bulb costs $5, while each incandescent bulb costs $1.
  • The average lifespan of an LED bulb is 25,000 hours, whereas the incandescent bulb’s is 1,200 hours.


  • Energy Consumption Comparison:
    • Annual energy consumption of one incandescent bulb:
    • 60W×5 hours/day×365 days/year=109.5kWh/year.
    • Annual energy consumption of one LED bulb:
    • 8W×5 hours/day×365 days/year=14.6kWh/year.
  • Annual Energy Cost Per Bulb:
    • Incandescent: 109.5 kWh \times $0.12/kWh = $13.14.
    • LED: 14.6 kWh \times $0.12/kWh = $1.75.
  • Total Annual Savings for 20 Bulbs:
    • Savings per bulb: $13.14 – $1.75 = $11.39.
    • Total savings: $11.39 \times 20 bulbs = $227.80.
  • ROI Calculation:
    • Initial investment for LEDs: $5 \times 20 bulbs = $100 (excluding incandescent bulbs as they are often already in place and need replacing).
    • Minus potential government rebate/incentive: Let’s assume a $20 rebate for energy-efficient upgrades.
    • Adjusted investment: $100 – $20 = $80.
    • ROI Timeframe: $80 / $227.80 annual savings = 0.35 years, or approximately 4 months.

In this example, the homeowner can recoup their investment in LED bulbs in just over 4 months, with significant annual savings afterward. Additionally, the long lifespan of LED bulbs means less frequent replacements, further enhancing savings over time.
