What feature in TraX helps users outline their travel costs before the trip?

The feature that helps users outline their travel costs before the trip is the budget planner. This tool is specifically designed to allow travelers to project, allocate, and manage their expenses in advance, ensuring they stay within predetermined financial limits for their trips. By enabling users to break down costs into categories such as accommodation, transportation, meals, and activities, the budget planner facilitates a comprehensive overview of expected expenditures.

In contrast, the other options serve different functions. The cost analysis tool typically reviews past spending patterns rather than assist in planning future expenses. The expense report summary feature is mainly utilized post-trip to compile and summarize actual expenses incurred during travel, rather than for pre-trip budgeting. Itinerary calculation may assist with planning schedules and logistics but does not inherently focus on financial aspects.
