Capital Expenditure Forecasting: The Annual CapEx Number Is Not the Forecast

The CapEx budget says $4 million.

The cash forecast also says $4 million.

So far, so good.

Then the project that was supposed to start in February starts in June, equipment requires a deposit nobody modeled, and a construction invoice crosses the year-end boundary.

The annual total may still be right.

The forecast is not.

Capital expenditure forecasting is usually less about the approved amount than the timing of the project behind it.

Separate approval from forecast

An approved project is permission to spend.

It is not evidence that the spend will occur exactly as budgeted.

I like keeping project approval status separate from forecast timing.

A project can be approved and delayed. It can be partially committed. It can be canceled. Scope can change.

When those states are hidden inside one annual number, Finance learns about the cash movement late.

Forecast projects, not one CapEx percentage

For material capital spending, I prefer a project schedule.

Project name. Owner. Approved amount. Amount committed. Expected timing. Cash-payment timing. In-service date where depreciation matters. Remaining forecast.

Not every laptop needs its own line.

Materiality should decide the detail.

Recurring small equipment can use a simpler run rate while large projects get explicit schedules.

Cash timing and accounting timing are different

This is where CapEx can confuse an otherwise clean model.

A deposit may leave cash before the asset is placed in service. Depreciation begins according to accounting treatment, not necessarily when the vendor is paid. A project may accumulate construction-in-progress before becoming a depreciating asset.

The forecast should respect those differences.

Otherwise the P&L, balance sheet and cash forecast can each contain a different version of the same project.

Do not let unused budget become automatic future spend

A project comes in $200,000 under budget.

That does not mean another department has discovered $200,000 of free money.

Budget authority and forecast expectation are different concepts.

If the project is complete, the forecast should release the unused amount unless management deliberately reallocates it.

This sounds obvious. Annual planning processes have a way of making unspent budget feel like a natural resource that must be extracted before December.

Maintenance and growth CapEx tell different stories

I like distinguishing spending required to maintain current operations from spending intended to create new capacity or growth.

Replacing aging equipment is different from opening a new facility.

The distinction helps management understand what can be delayed and what delay would actually cost the business.

It also improves scenario planning. A downside case may defer expansion projects while preserving critical maintenance.

Projects need trigger dates

The easiest CapEx forecast to maintain is one that knows what event should cause Finance to update it.

Contract signed. Purchase order issued. Deposit paid. Construction begins. Delivery moves. Project goes live.

Those are better signals than waiting for the monthly actual to appear.

If Finance only updates CapEx after invoices post, the forecast is describing cash movement after the business has already committed to it.

Reforecast the remaining project, not the original project

Once a project starts, the original budget becomes a reference point.

The forecast should focus on what remains.

Actual spend to date plus committed spend plus the current estimate to complete.

If the project is overrunning, show it. If timing moved, move it. If scope changed, update the expected total.

This is the same discipline behind a useful rolling forecast: preserve the target, but let the outlook change.

The CFO should be able to see the commitments

Cash surprises often begin before cash moves.

A signed contract, purchase order or approved project can create a future obligation that is invisible in current actuals.

A good CapEx forecast gives management visibility into that committed pipeline.

How much is already spent? How much is committed? What remains discretionary? When is cash expected to leave?

The annual CapEx number answers almost none of those questions.

It is a budget.

The project schedule is the forecast.
