Outdoor Lighting Cost Calculator
Estimate the cost to install or upgrade low-voltage outdoor landscape lighting — fixtures, transformer, wiring, and labor — by fixture count, grade, and DIY vs professional.
Planning landscape or outdoor lighting? This estimates the installed cost of a low-voltage setup — fixtures, the transformer, wiring, and labor — so you can budget before you buy. It updates as you adjust the project.
Number of fixtures
How many light fixtures the project includes — path lights, spotlights/uplights, step or deck lights, etc. A typical front-yard setup runs 6–12.
Fixture grade
Quality tier of the fixtures. Budget covers basic plastic/aluminum path and spot lights; Standard is quality LED; Premium is solid brass or architectural-grade.
Installation
Low-voltage (12V) landscape lighting is DIY-friendly. DIY removes the labor; a pro handles design, cable runs, and setup.
Smart controller / timer
An optional timer or smart (app/voice) controller to automate the lights. Leave off for a plain transformer with a basic photocell or dial timer.

A lot of this is labor — and it's DIY-friendly
Hiring out covers design, cable runs, and setup, and labor is often as much as the fixtures themselves. Low-voltage (12V) landscape lighting is one of the more approachable DIY outdoor projects, though — it runs on safe low voltage and usually needs no permit — so doing it yourself can cut the cost substantially if you're up for burying cable and placing fixtures.
Estimates use 2026 averages for low-voltage (12V) LED landscape lighting and will vary with fixture brand, yard layout, and region. They cover fixtures, a transformer, wiring/connectors, optional install labor, and an optional controller — but not line-voltage (120V) fixtures (which need an electrician and often a permit), trenching under driveways or patios, or major electrical work to add an outlet. LED fixtures last for years and cost very little to run, so ongoing energy cost is minimal.
💡About this calculator▼
Outdoor lighting transforms a yard — but the cost ranges from a weekend's DIY project to a four-figure professional install, depending on how many fixtures you want, how nice they are, and who does the work. This calculator gives you a realistic installed-cost range before you start buying fixtures or calling installers.
Enter how many fixtures you're planning, choose a quality grade, pick DIY or professional installation, and decide whether you want a smart controller. The tool adds up the fixtures, the transformer, the wiring, and any labor into a low-to-high total, broken down so you can see where the money goes.
The biggest swing isn't the fixtures — it's who installs them. Low-voltage (12-volt) landscape lighting is one of the friendlier outdoor DIY projects, so doing it yourself can roughly halve the cost of a professional install. The calculator makes that trade-off clear so you can decide where your project lands.
A low-voltage landscape lighting system has a few standard parts, and the calculator prices each one.
The fixtures are the main material cost: their price depends on how many you have and their grade. Budget fixtures are basic plastic or aluminum path and spot lights; Standard are quality LED units; Premium are solid brass or architectural-grade pieces built to last decades. The per-fixture cost climbs steeply with grade.
The transformer is the box that steps your household 120V down to the safe 12V the system runs on — every low-voltage setup needs one, sized to the total wattage of the fixtures. Wiring and connectors are the low-voltage cable that links the fixtures back to the transformer, scaled to the number of fixtures (more fixtures, more cable and connections).
Installation is the big variable. Choose DIY and the labor cost is zero — you're paying only for parts. Choose professional and the calculator adds an install charge per fixture, which covers the design, trenching, cable runs, and aiming; on a typical job, that labor rivals the cost of the fixtures themselves. Finally, an optional smart controller adds app, voice, or scheduling control beyond a basic timer.
Add the parts together for a low-to-high installed total. The exact formula and a worked example are below.
📐How it's calculated▼
The total is the sum of the parts, each carried as a low-to-high range.
Total = Fixtures + Transformer + Wiring + Install labor + Controller
- Fixtures = Number of fixtures × per-fixture cost (Budget ~$30–$60, Standard ~$60–$120, Premium ~$120–$250) - Transformer = ~$80–$300 (one, sized to the system) - Wiring & connectors = Number of fixtures × ~$5–$15 - Install labor = Number of fixtures × ~$50–$150 (professional only; $0 for DIY) - Smart controller = ~$30–$150 (optional)
Example: 8 Standard fixtures, professionally installed, no smart controller
→ Fixtures: 8 × $60–$120 = $480–$960
→ Transformer: $80–$300. Wiring: 8 × $5–$15 = $40–$120
→ Install labor: 8 × $50–$150 = $400–$1,200
→ Total: about $1,000–$2,580
Do that same job yourself and you drop the $400–$1,200 of labor, landing around $600–$1,380 — which is why DIY is so common for low-voltage lighting.

🔍Finding your inputs▼
Number of fixtures: How many individual lights the project includes — path lights along a walkway, spotlights or uplights on trees and the facade, step or deck lights, and so on. A modest front-yard accent setup is often 6–12 fixtures; lighting a whole property can run 20 or more. Count each light as one fixture.
Fixture grade: The quality tier, which drives the per-fixture price. Budget fixtures (basic plastic or cast-aluminum) are inexpensive but shorter-lived. Standard fixtures are solid quality LED units — the sweet spot for most homeowners. Premium fixtures are solid brass, copper, or architectural-grade, costing several times more but lasting decades and aging beautifully. You can mix grades in reality; pick the one that best represents most of your fixtures.
Installation: Choose DIY to price just the parts. Low-voltage landscape lighting is genuinely DIY-friendly — it runs on safe 12V, the wiring is forgiving, and most areas don't require a permit. Choose Professional to include installer labor, which covers lighting design, running and burying cable, and aiming each fixture; expect it to add roughly as much as the fixtures cost.
Smart controller / timer: Leave on "Basic timer" for a standard transformer with a photocell (dusk-to-dawn) or simple dial timer, which is included in the transformer cost. Choose "Smart controller" to add app, voice-assistant, or scene/scheduling control, which costs a bit more but lets you automate and adjust the lighting remotely.
⚠️Special situations▼
Should I do it myself or hire a pro?
Low-voltage lighting is one of the best outdoor projects to DIY. It runs on safe 12-volt power (not the 120V that needs an electrician), the cable connections are forgiving, and most jurisdictions don't require a permit. Doing it yourself removes the labor — often roughly half a professional bill. Hiring a pro buys lighting design (placement and aiming make a huge difference to the look), faster installation, and clean cable burial. If you're comfortable laying cable and willing to experiment with fixture placement, DIY saves a lot; if you want a designed, polished result fast, the labor is what you're paying for.
What size transformer do I need?
Add up the wattage of all your fixtures, then pick a transformer rated comfortably above that — a common rule is to use no more than about 80% of the transformer's capacity, leaving headroom for adding fixtures later. With LED fixtures (typically 3–7 watts each), even a dozen lights draw very little, so a modest transformer covers most home systems, which is reflected in the transformer range here. Larger or growing systems may need a bigger unit or a second transformer.
Are premium brass fixtures worth the extra cost?
It depends on how long you'll keep them and the look you want. Budget aluminum and plastic fixtures work fine but can corrode, fade, or crack within a few years, especially in harsh climates or near sprinklers. Solid brass and copper cost several times more but essentially last forever, develop an attractive patina, and rarely need replacing — so over a couple of decades they can be the cheaper choice. For a forever home or high-visibility front yard, premium often pays off; for a quick refresh or a home you'll sell soon, standard LED is the value pick.
I want to light my whole property, not just the front
Just scale up the fixture count — but plan the system, don't just multiply. Large installs may exceed a single transformer's capacity (you'll need a bigger one or a second), and long cable runs can cause voltage drop that dims the farthest fixtures, which is where a pro's design experience earns its keep. Budget for more wiring and possibly heavier-gauge cable on long runs. The per-fixture costs here still apply; the total simply grows with the count, and the orange 'premium project' range reflects a whole-yard scope.
Does outdoor lighting add much to my electric bill?
Barely, if it's LED. A typical LED landscape fixture draws only a few watts, so even a sizable system running dusk-to-dawn usually adds just a few dollars a month to your electric bill. (If you're replacing old halogen landscape lights — which drew 20–50 watts each — switching to LED cuts that running cost dramatically.) The real cost of a lighting project is the upfront install, not the electricity, which is why this calculator focuses on the project cost rather than ongoing energy.
❓Common questions▼
How much does outdoor landscape lighting cost?
A typical low-voltage landscape lighting project runs roughly $1,000–$2,600 for around 8 quality fixtures professionally installed, or about $600–$1,400 if you do it yourself. Small budget setups can be a few hundred dollars; large or premium whole-property installs can reach $5,000 or more. The biggest factors are the number of fixtures, their quality grade, and whether you hire a pro. Enter your specifics above for a tailored range.
How much does it cost to install landscape lighting per fixture?
All-in, professionally installed low-voltage fixtures commonly run about $110–$270 each once you fold in the fixture, a share of the transformer and wiring, and labor — with premium brass fixtures pushing higher. The fixture itself is roughly $30–$250 depending on grade, and professional labor adds about $50–$150 per fixture. Doing it yourself removes the labor portion. Multiplying a per-fixture figure by your count is a quick estimate; the calculator above does it precisely and adds the shared transformer cost.
Is low-voltage landscape lighting hard to install yourself?
It's one of the more DIY-friendly outdoor projects. The system runs on 12 volts stepped down by a transformer, so the shock risk is minimal and the wiring is far more forgiving than household electrical — you typically just connect fixtures to a cable and bury it a few inches deep. Most areas don't require a permit for low-voltage work. The trickiest part is design: placing and aiming fixtures for the best effect takes some experimentation. If you're comfortable with basic outdoor work, DIY can roughly halve the cost.
How many landscape lights do I need?
It depends on what you're lighting. For a front yard, many homeowners start with 6–12 fixtures: a few path lights along the walkway, two or three uplights on trees or architectural features, and a couple to wash the facade or house number. Lighting an entire property — back yard, sides, multiple trees, a patio — can take 20 or more. It's better to start with fewer, well-placed fixtures than to over-light; you can usually add to a low-voltage system later if the transformer has spare capacity.
Does landscape lighting use a lot of electricity?
Not with LED, which is now standard. LED landscape fixtures draw only a few watts each, so even a full system running every night typically adds just a few dollars a month to your electric bill — the energy cost is negligible compared with the upfront install. Older halogen landscape lighting used far more (20–50 watts per fixture), so if you're upgrading from halogen, LED slashes the running cost as a bonus. Either way, the money in a lighting project is in the fixtures and labor, not the electricity.
