Success Rate Calculator — Measure Performance & Probability

Success Rate Calculator

Calculate success rates, probability, and performance metrics. Analyze attempts vs successes with statistical confidence intervals.

Step 1: Success Data

Success Rate Formula

Success Rate = (Successful Attempts ÷ Total Attempts) × 100%. Confidence intervals calculated using binomial proportion confidence interval.

Step 2: Analysis Settings

Statistical Notes

Confidence intervals indicate the range where the true success rate likely falls. Higher confidence levels result in wider intervals.

Confidence Interval Analysis

Success Rate Formula

Success Rate = (Successes ÷ Total Attempts) × 100%

Confidence intervals calculated using the Wilson score interval formula for binomial proportions. This provides accurate intervals even with small sample sizes.
