The theory

Understanding Group Size Profitability.

Tour profitability is a balance between revenue and two types of costs: fixed and variable.

/ Formula

Fixed Costs are expenses you incur for the tour regardless of how many people show up. This includes your guide's salary for the day, vehicle rental, or non-refundable permits. Variable Costs are per-person expenses, such as snacks, bottled water, equipment rental, or commission to a booking agent. Understanding this distinction is key to finding your break-even point and identifying the most profitable group size.

Profit = (Group Size × Price Per Guest) - Fixed Costs - (Group Size × Variable Cost Per Guest)
/ Industry standard

The break-even point is the group size at which your total revenue equals your total costs, resulting in zero profit and zero loss. It's the minimum number of guests you need for a tour to pay for itself. Knowing this number is crucial for setting your minimum booking policies.

Questions, answered

Frequently asked questions.

A fixed cost is an expense that does not change with an increase or decrease in the number of goods or services produced or sold. For a tour, this is your guide's flat-rate pay or a park permit. A variable cost is an expense that changes in proportion to production output or sales. For a tour, this is the cost of a lunch or bottle of water for each guest.
Not necessarily. While it might generate the most revenue, it may not be the most profitable if your variable costs are high. Furthermore, you must consider non-financial factors. Does guest experience or safety suffer in a larger group? Does a larger group have a greater environmental impact? The 'best' group size is a balance of profit, quality, safety, and sustainability.
This calculator assumes fixed costs are constant across all group sizes. For a scenario with changing fixed costs, you should run the calculator twice. First, run it for group sizes 1-8 with the cost of one guide. Then, run it a second time for group sizes 9-16, but add the cost of the second guide to your 'Fixed Costs' input. You can then compare the results tables to find the true optimal size.
The break-even point is the group size at which your total revenue equals your total costs, resulting in zero profit and zero loss. It's the minimum number of guests you need for a tour to pay for itself. Knowing this number is crucial for setting your minimum booking policies and avoiding running tours that lose you money.
Yes, this is very normal. Your fixed costs are spread across more people as the group grows, so the impact of that cost on each individual guest becomes smaller. This causes the profit generated by each additional guest to be higher at the beginning. Don't focus too much on 'profit per guest'—the most important metric for decision-making is the 'total profit' for the tour.
