In construction, accurate forecasting isn’t a luxury — it’s a necessity. One of the most important metrics every contractor must understand is Cost to Complete (CTC). Whether you’re running one project or managing dozens, knowing how much more you’ll need to spend helps you stay profitable, stay on schedule, and avoid surprises.

This guide explains what cost to complete construction means, why it matters, and how tools like PivotXL can simplify the process.


What Does Cost to Complete Mean?

Cost to complete is the amount of money needed to finish a project. It includes expected costs for:

  • Labor and remaining work
  • Subcontractor commitments
  • Unpurchased materials and equipment
  • Indirect costs and overhead
  • Approved change orders

Contractors typically update this estimate every month. It plays a big role in work-in-progress (WIP) reporting and helps you stay compliant with ASC 606 revenue recognition rules.

Why Cost to Complete Matters

Knowing your cost to complete allows you to:

  • Recognize revenue accurately under ASC 606
  • Track job profitability in real time
  • Predict cash needs for the coming weeks
  • Identify risk early when jobs go over budget
  • Communicate clearly with clients and bonding agents

Without reliable CTC data, your WIP reports won’t reflect the true health of your projects — and you risk underbilling or misstating profits.


How Contractors Estimate Cost to Complete

Most construction companies follow a similar process each month:

  1. Pull actual job costs from your accounting system
  2. Ask project managers to estimate what’s left to spend
  3. Update spreadsheets with labor, materials, and sub estimates
  4. Calculate % complete based on total expected cost
  5. Review the data and build the WIP report

This process works — but it’s time-consuming, often manual, and prone to errors.


Challenges with Manual CTC Reporting

Many contractors rely on spreadsheets, which can create problems:

  • Slow turnaround: Reports can take days to finalize
  • Too much manual work: Copy-pasting data and checking formulas every month
  • No visibility: Teams work in silos with outdated templates
  • Version control issues: Multiple versions of the same file cause confusion
  • Missing audit trail: It’s hard to track changes or who made them

All of these issues can impact the quality of your financial reports — and make it harder to make informed decisions.
