Campground Utility Cost Per Site Calculator

Most campground owners discover they’ve made their utility math wrong when the July electric bill comes in. The air conditioners is on. The shower fills up. And then they look at their electric bill. The demand charge are higher than monthly rent for half of their inventory. That’s when you learn that dividing the total electricity bill by all sites, even if no one is occupying them, mean slow bankruptcy. Before setting your per-site rates, you must have an idea what a night on the ground cost you. So how do you go about it? Use the calculator above to handle the allocation logic, and concentrate on strategy.

The strategy is forcing yourself to break down your costs into variable versus fixed. What’s a variable cost? That’s what you pay for what you use: electricity (in terms of kilowatt-hours), water (gallons) and garbage (trash pickup). What’s a fixed cost? Those are your base bills regardless of whether there’s anyone in the park or not. Those are the fixed service fees for water and sewer line access. There are also demand charges, which is based off peak kilowatt usage rather than total energy consumed. This mix-up is the single biggest budgeting mistake managers make when running a hospitality business. It makes your profit margin per reservation impossible to see.

How to Calculate Your Utility Costs

Those numbers move on basis of occupancy. That means plugging in your average occupancy tells the tool how many days per site will be filled with guest who cover the fixed costs. There are one hundred sites with half occupancy. Each guest is not just paying for their own water and electricity; they’re also subsidizing vacant spot beside them. And if the subsidy is greater than room rate, the math gets ugly. So, the calculator wants your seasonal days. Why? Because a busy week in July isn’t the same as a slow Tuesday in November. Your utility costs vary by day of the year. Run the numbers for a stress test of full occupancy, will your demand charge eat your margin once the heat wave arrives?

Sewer and water are other expenses that can hide in the open. In most parks, it’s assumed that sewer flow equals water use. That doesn’t hold up in real life. Water used at the bathhouse for several sites will skew results. Leaky plumbing and irrigation of the lawn also skew things. By tweaking the sewer percent value on the tool, you can match sewer flow to actual water use. If your park features lots of trees and grass, such as in a campground setting, then more than just guest use will show up on your water bill. Should the excess water be considered part of site charge or handled as an operating overhead cost?

Same goes with garbage. Trash spikes disproportionately during holiday weekends. Spreading out the garbage costs over three hundred days softens the peak. This may work for annual budget purposes, but it does not work well when trying to analyze cash flows month by month. And then there’s the complexity of electric billing modes. To simplify things some parks bundle their electricity as part of site fee. This is great if your stay is short, but it is risky if it gets really hot or cold. Others bill electricity consumption directly by metering power used on a per kWh basis, moving the variable cost to the guest. The calculator models both.

If you choose to meter, how does that impact the fixed service fees and demand charges? Answer: those don’t magically go away because the guest now foots the kWh. Instead, they get shifted to other sites that aren’t billed. The result is a comparison grid showing how much cost will remain in the park regardless of the billing method. It underscores the tradeoff between what makes guests happy vs. Financially protecting yourself.

Admin overhead is the silent killer. There’s time spent on meter reading, billing, dispute resolution. The cost of all that work doesn’t factor into the net profit. Tacking on a tiny percent for administration recognizes the operational friction. When you’re working at thin margins, it’s a little line item that matters.

It’s a matter of getting the numbers right. And I don’t mean guessing; I mean knowing what you’re paying for. You give it context; the tool gives you the structure. Know when you use water and how much you use. Know what your peak loads are. Know what’s fixed, what’s variable. Do that, and you stop hoping the bills add up in the end: you’ll know they will. Air conditioners will run, but now you’ll know who’s paying for the breeze.
