Which term describes the practice of estimating future costs based on current data trends?

The term that describes the practice of estimating future costs based on current data trends is trend analysis. This method involves examining historical data over a specific period to identify patterns or trends that can be projected into the future. By analyzing these trends, appraisers and analysts can develop estimates concerning future costs, revenues, or other financial metrics.

Trend analysis relies on the assumption that past performance is indicative of future results, which makes it a powerful tool in financial forecasting and budgeting. It captures the dynamics of data variations and provides a basis for making informed decisions related to cost management and financial planning. Understanding these trends is crucial for accurate property and asset valuation in damage appraisal, as it allows professionals to make evidence-based predictions for future costs associated with repairs, replacements, or other necessary financial considerations.
