Enter the total length of stay, in nights, and the total cost of the stay into the calculator to determine the cost per night. This calculator can also determine the total cost or number of nights given the other variables are known.

Cost Per Night Formula

The following equation is used to calculate the Cost Per Night.

CPN = TC / N
  • Where CPN is the cost per night ($/night)
  • TC is the total cost ($)
  • N is the number of nights staying at the location

To calculate the cost per night, add together the total cost of the trip plus taxes, then divide by the length of stay in nights.

What is a Cost Per Night?


Cost per night is a way to define the average cost of staying at a hotel, or other location like an Airbnb, for one night. Typically the longer you stay at a place, the better the rate per night.

How to Calculate Cost Per Night?

Example Problem:

The following example outlines the steps and information needed to calculate the Cost Per Night.

First, determine the length of the stay. For this example, a couple is taking a vacation on a 7-night trip to the tropics.

Next, determine the total cost per night. Adding together the entire trip cost comes out to $10,000.00.

Finally, calculate the cost per night using the formula above:

CPN = TC / #N

CPN = $10,000.00 / 7

CPN = $1,428.5 /night
