An estimate is a calculation of the expected cost, time, and resources required to complete a project or task, based on available information, assumptions, and expertise. The accuracy of an estimate varies depending on the level of detail and complexity of the project, as well as the experience and expertise of the estimator.

Factors considered in preparing an estimate include the scope of work, materials and equipment, labor costs, overhead costs, and contingencies. The level of detail in an estimate can vary depending on the needs of the client or project team. An estimate is not a guaranteed cost, but it can provide a useful starting point for planning and budgeting a project.
