The second series contains the x value to look up and the resulting estimate of y.

The first series consists of the arrays of x- and y-values. The interpolation results can be shown on a graph by creating an Excel chart with two data series. Use Named Cells to make the formula much easier to understand:

This formula can be used in Excel to linearly interpolate the value of y: Instead, use the interpolation formula below, where y is the value to return, and x is the independent variable: It’s also possible perform linear interpolation in Excel without using the FORECAST function. =FORECAST(F3,F6:F7,F4:F5) How to Interpolate in Excel with the Interpolation Formula The only difference is that the array argument for the INDEX function is column C.įinally, use the FORECAST function as described above to return the estimated value of y: The formula for x2 returns 60 because the result returned by the MATCH function is increased by 1 to tell Excel to lookup the next row in the array.įor y1 and y2 the formulas are very similar. This tells the MATCH function to return a position from the temperature array that is less than the lookup_value when an exact match is not found. The formula returns 40 because the match_type argument in the MATCH function is set to 1. INDEX returns the actual value in the n th position of a row or column of data.īy using these functions together, we can extract the values of x1, y1, x2, and y2 we need for the interpolation. MATCH returns the location of a value (n) in a column or row of data. RELATED: USING EXCEL’S INDEX AND MATCH FUNCTIONS TO LOOK UP ENGINEERING DATA

The syntax for these functions is explained here, so if you need a refresher be sure to check that out. You can use the INDEX and MATCH functions to get the same results. If you are not a Microsoft 365 subscriber or are using an older version of Excel, the XLOOKUP function is not included. Use the INDEX/MATCH Functions for Interpolation in Excel But what if you need to interpolate missing data in Excel for better accuracy? Well, it’s also possible to perform linear interpolation in Excel, which enables you to estimate a y-value for any x-value that is not provided explicitly in the data. In some other posts on looking up tabular data in Excel, I’ve focused on how to extract known x- and y-values from a table. If you are on an older version of Excel, use the INDEX/MATCH method described below.

If you are a Microsoft 365 subscriber, or are using Excel 2021, Excel for the web, or Excel for iOS or Android devices, you can use the XLOOKUP function to extract the values. However, if you need even greater accuracy, you may want to consider a more advanced method such as cubic splines. In most cases linear interpolation in Excel will provide results that are sufficiently accurate. Linear interpolation assumes that the change in y for a given change in x is linear. To interpolate between x- and y-values in a large data set (more than 2 pairs of values), use either XLOOKUP or INDEX and MATCH to extract a pair of x- and y-values to interpolate between.
