Hotel Cost Per Person Calculator
Split a hotel stay fairly among a group by calculating the true per-person cost including taxes and fees. Perfect for friends trips, family vacations, or work travel reimbursements.
About this calculator
The true cost of a hotel stay is almost always higher than the advertised room rate once taxes, resort fees, and other surcharges are added. The formula is: Cost Per Person = ((roomRate + fees) × nights × (1 + taxRate / 100)) / people. First, the nightly room rate and any nightly fees are summed to get the true nightly cost. That figure is multiplied by the number of nights to find the gross stay cost. The tax rate is then applied multiplicatively — adding 1 to the decimal form of the tax rate before multiplying avoids the common error of applying tax only to the base rate. Finally, the total is divided by the number of people sharing the room to find the individual share. Hotel taxes in major US cities often run 14–18%, making this adjustment significant.
How to use
Your group of 3 books a hotel room at $120/night with a $15/night resort fee, staying 4 nights, in a city with 15% hotel tax. Enter: roomRate = $120, fees = $15, nights = 4, taxRate = 15, people = 3. The calculator computes: ((120 + 15) × 4 × (1 + 15/100)) / 3 = (135 × 4 × 1.15) / 3 = 621 / 3 = $207 per person. Without accounting for fees and tax, a naive split of (120 × 4) / 3 = $160 per person would leave each person $47 short of covering the actual bill.
Frequently asked questions
What fees should I include when calculating the true hotel cost per person?
Common nightly fees to include are resort fees, destination fees, amenity fees, and parking fees if applicable. These are charged per room per night exactly like the base rate and should be added to the room rate before any other calculation. One-time fees such as a pet fee or early check-in fee should be added to your total separately after the main formula. Always check your booking confirmation for a fee schedule, as these charges are frequently omitted from the headline price shown in search results.
How does hotel tax rate vary by city and how does it affect my total cost?
Hotel tax rates vary significantly depending on city, county, and state — and in many cases all three layers apply simultaneously. New York City's combined hotel tax is around 14.75% plus a per-room nightly surcharge, while Las Vegas runs approximately 13%. International destinations can be even higher; some European cities add tourist taxes on top of VAT. A difference of just 5 percentage points on a $150/night room over 5 nights adds $37.50 to the total bill, which is why using the actual local tax rate rather than guessing produces meaningfully more accurate results.
Is it cheaper to book separate hotel rooms or share one room when traveling in a group?
Sharing is almost always cheaper on a per-person basis, but the savings depend heavily on room capacity and pricing. A room at $150/night split two ways is $75/person, while a second room doubles the cost. For groups of three or four, suites or connecting rooms may offer better value than two standard rooms at comparable hotels. Factor in the non-financial costs of sharing — sleep disruption, privacy, and differing schedules — when making the final call, especially on longer trips where comfort significantly affects your enjoyment.
