What is the difference between committed cost and actual cost?

Whether the money has been paid. Committed cost is what the project is obligated to spend under a signed subcontract, an issued purchase order, or an executed change order, but has not yet been invoiced for. Actual cost is what has actually been paid or accrued against those commitments as the work is done and invoices come in. A subcontract signed for $1.0M is a $1.0M commitment on day one; the actual cost against it grows from zero toward $1.0M as the subcontractor bills. Tracking only actual cost tells you where the money has gone; tracking committed cost tells you where it is already promised to go, which is the earlier and more useful warning.

Why does committed cost reveal an overrun before actual cost does?

Because a commitment is made before the invoices arrive, sometimes months before. When a subcontract is awarded above its budget line, the overrun is locked in the moment the contract is signed, even though the actual cost against it is still zero and will not show the problem for weeks. A team watching only actual cost sees the overrun late, when the money is already spent; a team watching committed cost sees it at award, while there is still time to react, by resequencing, value-engineering, or covering it from buy-out savings. This is why disciplined cost control compares committed cost to the budget continuously, not just actual cost at month end.

How do committed cost, budget, and actual cost fit together?

They are three readings of the same cost line at different stages. The budget is the plan: what the estimate said the scope should cost. The committed cost is the obligation: what signed contracts and purchase orders now bind the project to spend, which may be above or below the budget once the work is bought out. The actual cost is the reality: what has been paid as the work proceeds. A healthy line has committed cost at or below budget and actual cost tracking toward committed. When committed cost exceeds the budget, the line is in trouble regardless of how little has been paid so far, which is exactly the signal cost control exists to catch.

CommittedCost

The overrun is locked in the day the contract is signed, not the day the invoice arrives. Committed cost is the warning that comes months before the money moves.

Definition

Committed cost is the value the project is contractually obligated to spend under signed subcontracts, issued purchase orders, and executed change orders. It sits between the budget, what you planned to spend, and the actual cost, what you have paid, with the portion not yet invoiced being the open commitment. Watching committed cost against the budget is how a team sees an overrun coming before the invoices arrive.

Between the plan and the payment

On our $10.8M cost budget, $5.4M is paid and another $2.6M is committed but not yet invoiced, an $8.0M total obligation. The committed line, not the paid line, is what tells you whether the budget still holds.

Three readings of the same line

Budget, committed, actual: the plan, the obligation, and the reality. The gap between committed and budget is the overrun you can still do something about.

Reading	Answers	Timing
Budget	What the estimate said it should cost	Set at award
Committed cost	What signed contracts + POs bind you to	At each award, before invoices
Actual cost	What has actually been paid	As invoices land

The budget-minus-committed gap at award is the buy-out buffer; the remaining spend is cost to complete.

How POD reads committed cost

POD reads each purchase order, subcontract, and executed change order as committed cost against the budget line it belongs to, and reconciles it alongside the actual cost from your pay applications, so the budget, the committed total, and the paid-to-date figure sit together instead of in three separate systems. A category whose committed cost has crossed its budget is visible at award, next to the field record, rather than at month-end close. POD reads and reconciles the commitments you upload; it does not negotiate your contracts or decide how to cover an overrun. What it removes is the lag between signing a commitment and seeing its effect on the budget.

Committed minus actual is work bought but not yet paid. Add the still-uncommitted scope and you have the cost to complete.
