What it means

An economy does not always use all the workers, machinery and buildings it has available. Economists compare what it is producing with an estimate of what it could keep producing without putting too much strain on those resources. If actual production is below that estimated level, the output gap is negative. If it is above it, the gap is positive. The sustainable level cannot be observed directly, so different estimates may disagree.

Example

If businesses have spare machinery and people who want work cannot find it, that may point to a negative output gap across the economy. One business with an idle machine would not establish the national figure on its own.

Why it matters

The estimate helps policymakers judge whether more spending might use spare capacity or add pressure to prices. It is an estimate, not a precise reading from a meter.
