What is Actual Cost?

Actual Cost (AC), historically termed Actual Cost of Work Performed (ACWP), is the total financial expenditure incurred in accomplishing work performed during a given period.

Formula

Actual Cost (AC) = Site Labor Expenditure + Material Invoices + Equipment Rental & Fuel + Subcontractor Payments + Indirect Overheads

Variables Explanation

- Site Labor: Payroll costs for site workers and supervisors.
- Materials: Invoiced cost of raw materials incorporated into work.
- Equipment: Machinery lease, maintenance, and fuel cost.
- Overheads: Site office utilities and supervision expenses.

How to Calculate

1. Enter direct site labor payroll cost.
2. Input material purchase invoices.
3. Input equipment rental and operational fuel expenses.
4. Input subcontractor and overhead costs to sum total AC.

Worked Example

Labor Cost: $45,000.
Material Invoices: $120,000 (concrete & steel).
Equipment Lease: $25,000 (crane & pumps).
Subcontractor & Overheads: $15,000.
Total Actual Cost (AC) = 45,000 + 120,000 + 25,000 + 15,000 = $205,000 (ACWP).

Practical Construction & Project Controls Use

Used by job cost accountants and project controllers to aggregate actual cost ledgers for Cost Performance Index (CPI) calculations.

Understanding the Result

Provides total actual cash outlay. Comparing AC against EV reveals cost efficiency (Under Budget vs Over Budget).

Limitations & Assumptions

Requires accurate accrual accounting so that material delivered and installed is matched with corresponding cost ledgers.
