The term Percent Error refers to the percentage-based difference between an item's known value and its approximate or measured value. It is used to report the discrepancy between the experimental value and its real or exact value in scientific experiments. It is calculated as a percentage of the precise value.
Percent Error \( = \frac{TV - OV}{TV} × 100\% \)
The calculation is sped up by using our online Percent Error Calculator, which shows the percentage error in the twinkling of an eye.
Calculations of percent error are useful in describing the precision of measurements based on predicted values. In addition to doing all that, this calculator helps you use fewer sheets of paper.
What is Percent Error?
The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.
When estimating the value of something, the percent error shows how far off you are from the actual value. Percentage errors may happen due to inaccurate material. Sometimes, those conducting experiments lack the necessary supplies, which can result in inaccuracy.
Percent Error Formula
This percent error can be calculated using the following formula:
Percent Error \(= \dfrac{TV – OV}{TV} × 100\% \)
TV = Theoretical Value
OV = Observed Value

Absolute Error vs. Percent Error
Absolute Error is the difference between an absolute measurement’s calculated and actual values.
Relative error vs. percent error
The relative error is equal to the absolute error divided by the result. While the Percent error is the difference between the correct value and the observed value divided by the actual value.
FAQs
What are the absolute maximum and minimum values?
The absolute maximum point is the location at which a function can reach its highest value. An absolute minimum point is where the function’s least possible value is obtained. These values can be found using an absolute maximum and minimum calculator.
What is the vector magnitude calculator?
A tool that assists you in estimating magnitude based on vector components is the vector magnitude calculator.
How to find the percent error for multiple data?
- You need to take the difference between the actual and estimated values.
- Multiply the outcomes from step 1 by the actual value.
- For the overall percentage, multiply the result by 100.
