How to Calculate Hotel Room Rate: The Hubbart Formula
Calculating the correct room rate is essential for hotel profitability. While dynamic pricing changes rates based on demand, every hotelier needs a "bottom line" rate—the minimum price required to cover costs and achieve a return on investment (ROI). This calculator uses the Hubbart Formula, a standard bottom-up approach used in the hospitality industry.
Understanding the Calculation Logic
The Hubbart Formula determines the Average Daily Rate (ADR) by working backward from your financial goals. Here is the step-by-step logic used in this calculator:
Calculate Total Required Revenue: Add your Total Annual Operating Expenses (staff, utilities, taxes) to your Desired Annual Profit (ROI).
Adjust for Non-Room Revenue: Subtract income generated from other departments like food and beverage, spa services, or parking. This gives you the net revenue that must be generated specifically by selling rooms.
Calculate Projected Room Nights: Multiply the total number of rooms in your property by the days open per year (usually 365) and your estimated Occupancy Rate.
Determine the ADR: Divide the Required Room Revenue by the Projected Room Nights.
Factors That Influence Your Inputs
Operating Expenses: Be thorough. Include undistributed operating expenses like administration, marketing, and property operation/maintenance.
Occupancy Rate: This is a critical variable. If you overestimate occupancy, your calculated rate will be too low to cover costs. It is safer to use a conservative estimate based on historical data or market averages.
Non-Room Revenue: For bed and breakfasts, this might be zero. For full-service hotels, this can be significant. Deducting this ensures you don't overprice your rooms by ignoring other income streams.
Why Not Just Use Competitor Pricing?
While looking at competitors (Compset) is vital for market positioning, it doesn't account for your specific cost structure. If your mortgage or utility costs are higher than the hotel next door, matching their price might lead to a loss. This calculator helps you find your "Break-Even Plus Profit" rate, which serves as your baseline price floor.

var totalRevenueRequired = expenses + profit;
// B. Room Revenue Required (Total – Non-Room Income)
var roomRevenueRequired = totalRevenueRequired – nonRoomRev;
// C. Calculate Total Room Nights Sold
// Formula: Rooms * Days Open * (Occupancy Percentage)
var totalRoomNights = rooms * daysOpen * (occupancy / 100);
// D. Calculate Average Daily Rate (ADR)
var adr = 0;
