Project costs not adding up correctly?

One possible cause is that you have inadvertently included fixed costs somewhere in the plan. The summary cost includes fixed costs for subordinate tasks, which can make your summary and total project costs look incorrect.

You can check to see if fixed costs are the cause by showing the fixed costs column in the Gantt or Task Sheet view:


Fix the problem by deleting the fixed cost or by entering zero for the fixed cost (you can enter fixed costs in a summary task).
