Online Calculators: calculate percent error

How to find percent error: To correctly put together the percent error equation, take the difference from accepted value which is also your result minus the accepted value, divide by accepted value and multiply this result by 100. This formula is always expressed as %.

Example how to calculate percent error: You estimated your monthly car payment to be $315. The actual car payment turned out to be $300. Calculate the percent error in these payments. First, take 315 and subtract 300 = 15. Next, take 15 and divide by the correct monthly car payment. 15/300=0.05. Finally, multiply 0.05 by 100=5%. The final percent error in your car payment estimate equals 5%.
