Cost trend analysis is a method of monitoring a project and the distribution of its costs. It is to align the budget for milestones, the entire project and the timely control of cost increases. Permanently monitored values are:

• Planned costs – what was originally planned for implementation.

• Actual expenses – what was actually spent on the work done.

• The cost of the work done is what was planned and actually spent on the work done. This includes the cost of work, materials, and external services.

• Space remaining is what is left to do and calculated as the difference between the amount of work planned and what was actually made by a certain time. Space remaining = planned costs – the cost of the work done.

• Additional expenses are the difference between actual and planned costs. Additional expenses = actual expenses – planned expenses.

V-fact is preliminary actual cost and a signal of overspending. V-fact = budget + additional expenses + space remaining.
