What is Forecast Accuracy?

How close forecasts are to actual results.

How to calculate it

Calculate Forecast Accuracy as: 1 − |Actual − Forecast| / Actual × 100. Pull the inputs from your connected data and track the trend over time in your dashboard.

Examples

Example 1

Forecast $480k, actual $500k -> 96% accuracy.

Example 2

A $480k forecast against $500k actual -> 96% accuracy, strong enough that leadership can plan hiring and spend against the next forecast.

Why it matters

Forecast accuracy measures how close forecasts are to actual results and underpins the credibility of planning and the quality of decisions built on it. Accurate forecasts let the business commit resources confidently, while poor ones erode trust in the planning process. Cherry-picking favorable periods gives a misleadingly rosy view.

Benchmark context

90%+ is strong for stable demand; volatile or early-stage businesses naturally forecast less accurately, so benchmark against your own variability.

Common pitfalls

Cherry-picking favorable periods.
