With this hot tub cost calculator, we aim to help you calculate the electric cost of your hot tub consumption. You can check out our electricity cost calculator and electricity cost – single usage calculator to understand more about this topic.

We have written this article to help you understand how to calculate the cost of your hot tub consumption. We will also demonstrate some examples to help you understand the concept.

How to calculate the hot tub cost?

To understand the hot tub cost calculation, let's look at the following example:

  • Power consumption: 1,000 W
  • Utility rate: $2/kWh
  • Usage: 2 hours

You can calculate hot tub cost in 4 steps:

  1. Compute the power consumption

    The first step is to compute the power consumption of the hot tub. That is how much power your hot tub consumes, and it should be displayed on the hot tub. In this example, the hot tub consumes 1,000 W. Please check out our electrical power calculator to facilitate this calculation.

  2. Determine the utility rate

    The next step is to determine the utility rate. This is how much you have to pay for every kWh of energy you consume. The utility rate of this hot tub is $2/kWh. This means you have to pay $2 for every 1 kWh of energy you consume.

  3. Determine the usage of the hot tub

    Now, you need to determine the hot tub usage, which is the number of hours you use the hot tub in a given time frame. For our example, the hot tub is used for 2 hours per day.

  4. Compute the hot tub cost

    The last step is to calculate the hot tub cost using the following formula:

    hot tub electric cost = power consumption / 1,000 × utility rate × usage

    Hence, the hot tub electric cost is 1,000 W / 1,000 × $2 / kWh × 2 hours = $4 per day.

How much is the hot tub electric cost per month?

Now that you have understood how to calculate the hot tub cost, you should be able to answer this question easily. It totally depends on your power consumption, the utility rate of your electric service provider, and the hot tub usage.

The higher the power consumption, utility rate, and usage, the higher the hot tub's electric cost per month.

FAQ

Can the power consumption of a hot tub be negative?

No, the power consumption of a hot tube cannot be negative. This is because a negative power consumption would mean the hot tub is generating power instead of using it.

How can calculate the hot tub electric cost?

You can calculate the hot tub electric cost in four steps:

  1. Find or compute the power consumption.

  2. Determine the utility rate.

  3. Determine the usage of the hot tub – the average number of hours per day.

  4. Apply the hot tub cost formula:

    hot tub electric cost = power consumption / 1,000 × utility rate × usage.

What will be the hot tub cost if there is no usage?

The hot tub electric cost will be $0 since there is no usage. However, in reality, the hot tub will consume at least a little bit of energy, even if you do not use it.

How much does a hot tub cost?

An average price of a hot tub can range from about $3,000 to $16,000. However, depending on the level of luxury, some can go way beyond those numbers.
