(1) Use the formula =ROUNDUP(C2,4) to round up percentage values to two decimal places; (2) use the formula =ROUNDDOWN(C2,4) to round down percentage values to two decimal places; (3) use the formula =ROUND(C2, N+2) to round percentage values to N decimal places.

Subtract the benchmark number from the new number, then divide the result by the benchmark number to get the percent variance. The calculation in this case is as follows: (150-120)/120 = a quarter-point-percentage-point-percentage-point-percentage-point You sold 25% more widgets today than yesterday, according to the percent variance.

  • Using the AVERAGE function, get the mean: =AVERAGE(B2:B7)
  • Subtract the average from each of the sample numbers:
  • Divide each difference by two and enter the results in column D, starting with D2:
  • Divide the sum of the squared differences by the number of items in the sample minus one:

  • In Excel, make sure your data is in a single range of cells.
  • Enter the formula "=VAR" if your data represents the entire population.
  • In the cell, the variance for your data will be displayed.
