Budgets, commitments and actual costs: three different views of spending

A budget is an agreed financial plan for a defined responsibility, scope and period. A commitment describes spending the business has undertaken but may not yet have fully realised. Actual cost describes recorded activity. These measures answer different questions; none is the same as the cash balance in the bank.

A company can be within its actual spending limit and still have little room for another order because it has already committed the remaining resources. Conversely, an apparently low actual cost can reflect late invoices or incomplete recording rather than genuine savings.

How DNA connects the measures

DNA relates budgets to cost centres and supports cost lines organised by general-ledger accounts or cost codes. Its budget-check results distinguish budget, committed, actual and available amounts, the current transaction, and the amount available after it. The result also states whether proceeding is allowed and whether an override is required.

The Budget vs Actual view applies a specific calculation to the returned totals: outstanding obligation is the larger of zero and committed minus actual; available budget is budget minus the larger of committed and actual. This matters because the displayed commitment and actual figures must not simply be added as if they were unrelated amounts.

A worked example

Northstar Services has a budget of USD 100,000, commitments of USD 60,000 and actual cost of USD 40,000. Under that view's calculation, the outstanding obligation is USD 20,000 and available budget is USD 40,000. Subtracting both USD 60,000 and USD 40,000 from the budget would double-count overlapping exposure.

If actual cost rises to USD 70,000 while the commitment figure is USD 60,000, the same calculation gives zero outstanding obligation and USD 30,000 available. It does not ignore actual spending above the commitment figure.

These examples explain the view's calculation. Transaction checks return their own available and after-transaction amounts and permissions; those returned results must be interpreted in their transaction context.

What the comparison does not establish

Available budget does not prove that cash is available, that a purchase is technically suitable, or that an approval requirement has been met. It describes room within a particular financial plan. Supplier terms, liquidity, authority and operational need remain separate considerations.

A useful review establishes the scope and period, understands the calculation, and traces important differences to the underlying records. Budget control is strongest when it supports decisions before commitments are made, while actual-cost analysis explains what eventually happened.
