Garage door openers have become a staple of modern home convenience. They provide security, automation, and ease of access, especially when integrated with smart home systems. But as energy costs continue to rise, homeowners are becoming increasingly curious: How much power does a garage door opener use?
While garage door openers aren’t typically the biggest contributors to your electricity bill, they do consume energy—both during operation and while sitting idle. In this article, we’ll break down exactly how much power these devices use, explore different types of openers, look at standby consumption, and provide tips on how to reduce your energy costs over time.

How Much Power Does A Garage Door Opener Use – The Complete Breakdown
Understanding how much electricity your garage door opener uses requires looking at two modes of power consumption: active usage (when opening/closing the door) and standby mode (when the opener is idle but ready to receive a command).
1. Power Consumption During Operation
When your garage door opener is in use—i.e., when it’s opening or closing the door—it draws the most electricity. On average:
- Garage door openers use 350 to 600 watts while operating.
- The motor typically runs for 10–15 seconds per use, meaning the overall energy used per operation is low.
Let’s break it down further with an example:
- If your opener uses 500 watts and operates for 15 seconds, that’s:
- 500 watts×15 sec3600=2.08 watt-hours\frac{500 \text{ watts} \times 15 \text{ sec}}{3600} = 2.08 \text{ watt-hours}3600500 watts×15 sec=2.08 watt-hours per use.
Assuming you open and close the garage door four times a day, your total daily usage is:
- 2.08×4=8.32 watt-hours/day2.08 \times 4 = 8.32 \text{ watt-hours/day}2.08×4=8.32 watt-hours/day
That translates to about 2.5 kilowatt-hours (kWh) per year—a minimal amount by most household standards.
2. Standby Power Consumption
What surprises many homeowners is that garage door openers draw power even when they’re not in use. This is called phantom load or vampire power.
On average:
- Most openers consume 4 to 8 watts in standby mode.
- Over 24 hours, that’s:
- 6 watts×24 hrs=144 watt-hours/day6 \text{ watts} \times 24 \text{ hrs} = 144 \text{ watt-hours/day}6 watts×24 hrs=144 watt-hours/day
- Over a year, standby usage could total:
- 144×365=52,560 watt-hours144 \times 365 = 52,560 \text{ watt-hours}144×365=52,560 watt-hours or 52.5 kWh/year
If you pay $0.15 per kWh, that’s nearly $8 annually just for standby power—more than the power used during actual operation!
3. Energy Use by Opener Type
Different types of garage door openers use varying amounts of power depending on their design and technology.
| Opener Type | Operating Power | Standby Power | Notes |
|---|---|---|---|
| Chain Drive | 400–600W | 5–7W | Most common; generally loud and older |
| Belt Drive | 350–500W | 4–6W | Quieter, smoother, slightly more efficient |
| Screw Drive | 500–600W | 5–8W | Powerful but higher maintenance |
| Direct Drive / Jackshaft | 300–400W | 3–5W | Most efficient and modern |
Newer models, particularly ENERGY STAR-rated openers, tend to use less standby power than older models.
Factors That Affect How Much Power a Garage Door Opener Uses
There are several key variables that influence how much electricity your garage opener consumes:
a. Motor Size and Efficiency
Older motors tend to be less efficient, consuming more watts during use. Some premium models include DC motors, which are quieter and use less power than traditional AC motors.
b. Door Size and Weight
Larger or insulated garage doors require more torque to lift, meaning the opener needs more power to do the job. A double garage door or heavy wood-paneled door will cause your opener to draw more current.
c. Frequency of Use
A household that uses the garage door once per day will consume far less energy than one that opens and closes it 10 times daily.
d. Smart Features
Modern garage openers often come with:
- Wi-Fi connectivity
- Cameras
- Motion detectors
- Smartphone integration
These features add small but consistent standby power draw.
How to Calculate the Energy Cost of Your Garage Door Opener
To calculate how much energy your opener uses and what it costs, use this simple formula:
sqlCopyEditPower (in kWh) = (Watts × Hours of use per year) / 1000
Cost = Power (in kWh) × Cost per kWh
Let’s say your opener:
- Uses 500 watts per use
- Operates 4 times per day for 15 seconds each
- Has a standby draw of 6 watts
Step 1: Calculate annual operating power
- 4 uses/day × 15 sec = 60 sec/day = 1 minute
- 500W × (1/60) hrs = 8.33 Wh/day
- Annual: 8.33 × 365 = 3,041 Wh = 3.04 kWh
Step 2: Calculate annual standby power
- 6W × 24 = 144 Wh/day
- Annual: 144 × 365 = 52,560 Wh = 52.56 kWh
Step 3: Add them up
- Total = 3.04 + 52.56 = 55.6 kWh/year
Step 4: Estimate cost
- If your electricity rate is $0.15/kWh:
- 55.6 × $0.15 = $8.34 per year
How to Reduce Power Usage from Your Garage Door Opener
If you want to reduce the amount of power your opener uses, especially standby power, here are some practical tips:
1. Unplug During Extended Absences
If you’re going on vacation or won’t be using the garage for a while, unplug the opener to eliminate standby power.
2. Upgrade to an ENERGY STAR Model
Look for garage openers with ENERGY STAR ratings. These use as little as 1 watt on standby, significantly lowering your yearly energy consumption.
3. Use a Smart Plug with Scheduling
Smart plugs allow you to cut power to the opener at night or during set hours. Just ensure it doesn’t interfere with safety features or remote access.
4. Limit Extra Features
If you’re not using smart home integrations, consider turning off Wi-Fi or camera functions when unnecessary.
Common Myths About Garage Door Opener Power Usage
Myth 1: “Garage door openers use a lot of electricity.”
Truth: They use very little during operation—comparable to a light bulb. Most of the cost comes from standby usage.
Myth 2: “Opening the garage frequently drastically increases bills.”
Truth: Frequent use has some impact, but it’s still minimal compared to appliances like HVAC systems or refrigerators.
Myth 3: “Smart openers are always more efficient.”
Truth: While convenient, smart openers may consume more standby power unless specifically designed to be energy-efficient.
FAQs: How Much Power Does A Garage Door Opener Use?
Q1: Does the opener use electricity even when not in use?
Yes, most garage door openers consume 4 to 8 watts on standby, 24/7.
Q2: Can I use solar power to operate my garage door opener?
Yes, you can power your opener using a solar-powered battery backup system, especially in off-grid or eco-friendly setups.
Q3: How much does it cost monthly to run a garage door opener?
Usually less than $1/month, assuming average usage and power rates.
Q4: What’s the most efficient type of opener?
Direct drive openers with DC motors are typically the most energy-efficient.
Final Thoughts
So, how much power does a garage door opener use? The answer is: surprisingly little. While standby power contributes more than the actual operation, the annual cost is still quite low—generally under $10 per year for most households.
However, being energy-conscious is always a good idea. If you’re looking to cut costs, reduce phantom load, or upgrade to a more efficient system, small changes can make a noticeable difference over time.
