How to calculate led retrofit savings
This calculator finds annual savings from switching to LED lighting by subtracting new (LED) annual energy cost from old annual energy cost.
How the calculation works
Annual savings = Old annual energy cost − New annual energy cost.
Example
Old lighting costing $800/year, new LED lighting costing $220/year: Annual savings = 800 − 220 = $580/year.
Frequently asked questions
How do I calculate LED retrofit payback period?
Divide the total upfront cost of the LED retrofit by the annual savings calculated here. For example, a $2,000 retrofit with $580/year in savings has a payback period of about 3.4 years.
LED Retrofit Savings
Annual savings = Old annual energy cost − New annual energy cost.

Pro Tips for LED Retrofit Savings
- Include both energy savings and any reduced maintenance/replacement cost (LEDs last much longer than incandescent or fluorescent) for a complete picture of total savings.
- Divide the upfront LED retrofit cost by annual savings to estimate a simple payback period in years.
Common LED Retrofit Savings Mistakes to Avoid
- Calculating energy savings alone without accounting for the retrofit's upfront cost when evaluating whether the investment makes financial sense.
