Campsite Cost Split Calculator
Split the total cost of a campsite, cabin, or group rental evenly among your group based on nightly rate, number of nights, and group size.
How the share is worked out
An even split of the whole booking, not a per-night bill:
total cost = nightly rate × nights
cost per person = total cost / peopleAt the default $50 a night for 3 nights the site costs $150, and four campers owe $37.50 each. Nights and people must be at least 1, and the rate has to be above zero - a free permit site shows the error message instead of $0.00.
What to put in the nightly rate
Use the figure the whole group is liable for, which is rarely the headline price on the reservation page. State and national park bookings usually add:
- A reservation or booking fee, often $8 to $12, charged once per stay - divide it across the nights and add it to the rate.
- Extra-vehicle charges, typically $5 to $10 a night, when the group arrives in two or three cars.
- Per-person fees above the site's included headcount, common once a party passes six.
For an uneven trip, where someone joins late, run the numbers in person-nights rather than forcing one answer. Three people for 3 nights and one for 2 is 11 person-nights, so $150 divided by 11 is $13.64 a night each: $40.91 for the full stay and $27.27 for the shorter one.
Frequently asked questions
How much does a campsite cost per night?
Typically $20 to $40 for a standard site in a US state or national park, $50 or more for a group site with hookups, and nothing at all for dispersed camping on national forest land.
Should the person who books pay less?
They already carry the cancellation risk and the card charge, so many groups split evenly and let the booker skip the firewood or the ice run instead.
How do we split a site when people stay different nights?
Count person-nights. Add up each camper's nights, divide the total cost by that number, and charge each person their own nights at that rate.
