What These Numbers Mean
A quick guide to each figure above — in plain terms — so you can explain the value to your customer.
Proposed Annual Savings
How much money the new lights save on the power bill every year,
compared to the existing lights.
Energy Savings
How much less electricity (in kWh) is used each year. Lower energy
use also means a smaller carbon footprint.
Proposed Simple Payback
How long until the energy savings pay back the cost of the upgrade.
After this point, the savings are money in your pocket.
Monthly Cost of Waiting
The savings lost for every month the upgrade is delayed — the price
of sticking with the old lights a little longer.
10-Year Savings
The total saved over ten years — a sense of the long-term payoff of
switching to LED.
Annual Cost & Energy
On each side, the yearly power cost and electricity used — the
“Baseline” is today’s lights, the “Proposed” is the LED upgrade.
Tip: the charts show how the two options compare over time — the point where the lines cross is roughly your payback moment.
