📊 Achievement Rate Calculator

📌 Achievement Rate Formula
• Achievement Rate (%) = (Actual ÷ Target) × 100
• Below 100%: Target not achieved
• 100%: Target achieved
• Above 100%: Target exceeded

💡 Usage Examples
• Sales target: 100M, Actual: 120M → Rate: 120%
• Sales target: 500 units, Actual: 450 units → Rate: 90%
• KPI target: 80 points, Actual: 85 points → Rate: 106.25%

⚠️ Notes
• Target value must be greater than 0
• Higher rate is not always better (e.g., cost targets)
• Accurate goal setting is key to performance measurement

What Is an Achievement Rate?

The achievement rate is a metric that expresses, as a percentage (%), the ratio of the actual result to the target you set. It is used to objectively measure performance in any area with quantitative goals, such as sales, sales volume, output, or KPIs. For example, if the sales target is 100 million KRW but actual sales are 80 million KRW, the achievement rate is 80%, meaning you reached 80% of the goal. Achievement rates are widely used, from evaluating individual work performance to managing an organization's strategic objectives.

How to Calculate the Achievement Rate

The achievement rate is calculated by dividing the actual value by the target value and multiplying by 100. That is, Achievement Rate (%) = (Actual ÷ Target) × 100. A result below 100% means the target was not met, exactly 100% means the target was achieved, and above 100% means the target was exceeded. For example, with a target of 500 units and an actual of 450 units, (450 ÷ 500) × 100 = 90%. Because division by zero is undefined, the target value must always be greater than 0.

Practical Examples

The achievement rate is useful in many situations. A sales target of 100 million KRW with an actual of 120 million KRW gives a 120% rate, meaning the goal was exceeded. A sales target of 500 units with an actual of 450 units gives 90%, slightly below target. A KPI target of 80 points with an actual of 85 points gives 106.25%, above expectations. Calculating the achievement rate lets you grasp progress toward a goal at a glance and helps you address shortfalls or analyze the reasons behind over-performance.

Points to Note When Interpreting

A higher achievement rate is not always better. For metrics where lower is better, such as cost, defect rate, or churn rate, a rate above 100% may actually indicate a worse outcome than the target, so you should first consider the nature of the metric. In addition, if the target itself is set too low, a high achievement rate may carry little real meaning. Accurate and reasonable goal setting is the key to using the achievement rate properly as a performance measurement tool.
