What is committed cost in construction?

Committed cost is money you've promised but not yet paid — the value of purchase orders you've issued and subcontracts you've signed. The work isn't invoiced yet, but the cost is locked in, so it belongs in your view of where the job's budget stands.

What is the difference between committed and actual cost?

Committed cost is money promised (POs and signed subs); actual cost is money already spent and invoiced. A cost code can look under budget on actuals alone while committed costs will push it over — which is why tracking both gives the true picture.

Committed Cost vs Actual Cost in Construction (and Why Both Matter)

Q: Why track committed cost?

Because actuals lag reality. If you only watch what you've spent, a code can look fine right up until the invoices for work you already committed to arrive. Tracking committed cost shows the overrun before it hits, while you can still act on it.

If you track a job only by what you've spent, you're always looking at the past. A cost code can read comfortably under budget while you've already signed subcontracts and issued POs that will blow right through it. The fix is to track two numbers, not one: what you've spent, and what you've promised.

The two numbers

Actual cost — money already spent and invoiced. What's left your account or hit your books.
Committed cost — money you've promised but not yet paid: the value of purchase orders you've issued and subcontracts you've signed. Not invoiced yet, but locked in.

Your real exposure on a cost code is closer to actual plus committed. Ignore the committed side and you're flying on stale information.

Why it matters — a quick example

Say your electrical budget is $8,000. You've paid $3,000 so far, so on actuals you look 63% under budget — comfortable. But you've also signed the electrician's contract for the remaining rough-in and finish at $6,000. Actual + committed is $9,000 — already $1,000 over. On actuals alone you don't see it until the invoice lands and it's too late to renegotiate. Tracking committed cost shows it now.

The point Actuals tell you what already happened; committed cost tells you what's about to. Watch both and an overrun shows up while you can still do something about it.

You don't need enterprise software for this

Big project-management platforms track committed cost automatically, but you can do the same thing in a spreadsheet: budget by code, log both what you've committed and what you've spent, and compare the total to budget. It's exactly the kind of early-warning view that keeps a job's margin from eroding without you noticing.

Committed is promised; actual is spent. A code can look under budget on actuals while committed costs will push it over.

Why track committed cost?
