How Much Does It Cost to Run Landscape Lighting?
Ten low-voltage LED fixtures draw about 50 watts total — all-evening curb appeal for a dollar or two a month. At the US-average rate of 16.5¢/kWh, running landscape lighting costs about $1.50/month ($18.05/year) at typical use. Adjust the watts, hours, and your rate below for your exact number.

Cost = power (kW) × hours × days × your rate. Defaults are typical values — enter your appliance's actual watts (often on a label) and your real rate for a precise figure.
How much electricity does landscape lighting use?
At 50 W for 6 hours a day, landscape lighting uses about 0.3 kWh per day — roughly 9 kWh per month and 110 kWh per year. That's about 1% of the 863 kWh the average US home uses in a month. Energy use is the same everywhere — only the price per kWh changes your bill.

Measure what landscape lighting really costs you
The estimate above uses typical wattage and hours. A plug-in energy meter logs the kilowatt-hours this appliance actually uses — leave it in for a week, multiply by your rate, and the estimate becomes a measurement. A whole-home monitor does the same for every circuit at once, but its sensors install inside the panel.
