Accuracy % = (Correct Entries ÷ Total Entries) × 100. Results are calculated in your browser and are not stored.
How to use this
- 1. Count the records, rows, or fields in the batch you completed.
- 2. Have someone verify a sample — or re-check it yourself against the source — and count real errors.
- 3. Compare the result against the standard your task or employer specifies.
- 4. Track the number over several batches. A single batch tells you little; a trend tells you a lot.
