What Does It Cost to Charge a Golf Cart?
Around a dollar a charge for most carts — here's the actual kWh maths, how to work it out for your own electricity rate, and how to pay less.
Charging a golf cart costs roughly $0.50 to $1.50 for a full charge for most electric carts. That's the headline, but the number depends entirely on your battery capacity and your local electricity rate — and it's easy enough to calculate exactly rather than rely on someone else's average.
Here's the maths, and what it works out to over a year.
The calculation
Charging cost comes down to one formula:
Battery capacity (kWh) ÷ charger efficiency × your electricity rate ($/kWh)
To get your battery capacity in kWh, multiply the pack voltage by its amp-hour rating and divide by 1,000. A 48V pack rated at 170Ah is:
48 × 170 ÷ 1,000 = 8.16 kWh
At a typical residential rate of $0.12–$0.16 per kWh, a full charge of that pack costs roughly $0.98 to $1.30, before accounting for charging losses.
Typical costs by setup
| Pack | Approx. capacity | Cost per full charge |
|---|---|---|
| 36V lead-acid | ~6 kWh | ~$0.70–$0.95 |
| 48V lead-acid | ~8 kWh | ~$0.95–$1.30 |
| 48V lithium | ~5–7 kWh usable | ~$0.70–$0.95 |
Lithium comes out cheaper per charge for the same real-world range, for two reasons: it charges more efficiently, so less of what you pay for is lost as heat, and more of its nominal capacity is actually usable. Lead-acid should only be discharged to around 50% to protect its lifespan, which means you're regularly recharging a pack you only half-used.

What it costs over a year
Charging three times a week at around a dollar a charge works out to roughly $150 a year. Daily charging lands nearer $350.
For context, that's the running cost of the vehicle in full — there's no fuel, no oil, no filters. Compare it against a gas cart's fuel bill alone and the gap is substantial, which is a large part of why electric dominates neighborhood and resort use now. See electric vs gas golf carts.
Finding your own numbers
Your electricity rate is on your utility bill, usually shown as cents per kWh. Use the all-in rate including delivery charges, not just the supply portion — the difference is often significant.
Your battery capacity is on the battery label or the cart's spec sheet. Every model page on our site lists the battery in its specs.
Charger efficiency is typically 85–90% for a modern charger. Divide by 0.85 to be conservative — you pay for what goes into the charger, not what reaches the battery.
Measuring what you're actually using
If you'd rather know than estimate, a plug-in energy monitor between the outlet and the charger costs very little and settles it. Charge from empty to full once with the meter in line and you have your real per-charge figure, including charger losses — no assumptions about efficiency required.
It's also a useful diagnostic. If the kWh per charge climbs over months while your driving stays constant, that points at either an ageing pack drawing more to reach the same state, or a charger becoming less efficient. Either way it's an early warning worth having.
For most owners this is optional. It's genuinely worth doing if you're running several carts, if you're on a time-of-use tariff and want to confirm the saving, or if you're trying to work out whether a lithium conversion pays for itself.
How to pay less
Charge off-peak. If your utility offers time-of-use pricing, overnight rates are often substantially cheaper. Since most people charge overnight anyway, this is close to free money — but only if you're actually on the right tariff, so check.
Don't leave it plugged in indefinitely. Modern chargers taper off, but a lead-acid charger left connected for weeks still draws some power and can cook the pack over time.
Keep tires properly inflated. Not a charging saving as such, but you'll travel further per charge, which is the same thing in practice. Underinflation is the most common avoidable range loss.
Charge fully rather than in short bursts if you're on lead-acid. Partial charging shortens its life, and a pack replaced sooner costs far more than any electricity saving.
Consider lithium if you're charging daily. Higher efficiency and greater usable capacity mean fewer kWh for the same distance — see converting a golf cart to lithium.
Charger types and how they affect cost
The charger itself doesn't change what a kilowatt-hour costs, but it does change how much of what you pay actually reaches the battery.
Onboard chargers are built into the cart — plug into a standard outlet and go. Convenient, and what most modern carts ship with.
Portable chargers live separately and plug in when needed. Slightly cheaper to replace, one more thing to carry.
Lithium-specific chargers use a different charging profile from lead-acid ones. Using the wrong type doesn't just cost efficiency — it can damage the pack outright. This matters if you convert; see converting a golf cart to lithium.
Older or failing chargers waste noticeably more energy as heat. If your electricity use has crept up without your driving changing, an ageing charger is a plausible cause.
Can you charge from solar?
Yes, and for some owners it works well — a modest rooftop or carport array generates enough over a day to cover typical cart use, since a full charge is only a few kilowatt-hours.
Two honest caveats. First, if you already have home solar, charging the cart during daylight simply uses generation you'd otherwise export, which is usually the better value — no new hardware required. Second, installing solar specifically to charge a cart rarely pays back on its own: at $150–$350 a year of electricity, the payback period on a dedicated array is very long.
Solar makes sense as a small addition to an existing system, or where running mains power to where the cart lives would be expensive.
Electricity vs gas, in real numbers
A gas cart burning a few gallons a week at pump prices costs several times what the equivalent electric charging does — before you add oil changes, filters, spark plugs and the servicing a combustion engine needs.
The gap widens over years of ownership. It narrows only when you factor in eventual battery replacement, which is the one significant electric-specific cost. Lithium's longer life pushes that far enough out that electric generally stays ahead over a decade. The full comparison is in electric vs gas golf carts.
Charging cost in context
It's worth keeping this in proportion. At $150–$350 a year, electricity is one of the smaller costs of owning a cart. The expenses that actually move the budget are the purchase price, eventual battery replacement, and insurance if you're financing or running an LSV on public roads.

Common questions
How much does it cost to fully charge a golf cart? Typically $0.50–$1.50 depending on pack size and your electricity rate. A 48V lead-acid pack at average US rates comes out around a dollar.
Is it cheaper to charge at home or at a course? Home is usually cheapest, and some courses offer charging free as an amenity. Public charging for carts is uncommon.
Does leaving it plugged in cost much? A modern charger draws very little once the pack is full, but leaving a lead-acid cart connected for weeks is bad for the batteries regardless.
How much electricity does a golf cart use per year? Roughly 150–350 kWh for typical use — three charges a week to daily charging.
Does fast charging cost more? No. Cost tracks energy delivered, not speed. Lithium simply accepts it faster.
Can I charge a golf cart from a normal household outlet? Yes. Standard cart chargers run from an ordinary 110V household outlet. Use a dedicated circuit where you can, and avoid running through a long extension lead — voltage drop makes charging slower and less efficient.
Is it cheaper to charge lithium or lead-acid? Lithium, for the same real-world range. It charges more efficiently and more of its capacity is usable, so fewer kilowatt-hours go in for the same distance out.
Does cold weather increase charging cost? Somewhat. Cold reduces available capacity and charging efficiency in any chemistry, so you pay slightly more per usable mile in winter. The effect is more pronounced on lead-acid.
How long does a full charge take? Lead-acid typically 8–10 hours; lithium usually 2–5. Most owners simply charge overnight, which makes the difference academic unless you need a mid-day top-up.
Should I unplug the charger once it's full? Modern chargers taper off and are designed to be left connected short-term. For storage over weeks, disconnect and top up periodically instead of leaving it plugged in continuously.
Does charging cost more than a course's cart fee? Nowhere close. At around a dollar per charge, home charging is a fraction of what a single rental round costs, which is a large part of the ownership argument.
Figures are estimates based on typical residential electricity rates and standard pack sizes. Your actual cost depends on your utility rate, battery capacity, charger efficiency and how deeply you discharge between charges.
