If you have four total records and only three sets are returned, how do you calculate the percentage of records retrieved?

To calculate the percentage of records retrieved, divide the number of records you actually received by the total number of records expected, then multiply by 100. In this case, you received 3 out of 4 records. So you compute (3 ÷ 4) × 100 = 0.75 × 100 = 75%. This means 75% of the expected records were retrieved. The formula is straightforward: (retrieved / total) × 100. It’s a basic arithmetic operation used frequently in data quality checks, reporting, and monitoring to express completeness or success rates.
