Thanks for posting an explanation of the problem. I do need a worksheet-formula-only way to do the interpolation (e.g. no VBA or macros), and I would like a smooth curve a la spline or similar. For now I have switched to the Legendre formula, and that seems to work OK for the t...
The firstFOR loopwill return the sales values for any day which is present in the day’s ranges and the secondFOR loopwith theIF-Thenstatement will store value to thesmall_incrementandlarge_incrementvariables. Using the formula for calculating interpolation, this function will return our desired ...
Method 6 – Using INDEX and MATCH Functions to Do Linear Interpolation Use the following formula for x1: =INDEX(C5:C14,MATCH(G8,C5:C14,1)) Here, G8 is the value of Day 85 (x) for which you want to interpolate. The above formula finds the value of x1 where the MATCH function ...
To create a sample linear interpolation formula, follow these steps: Type the following values in a worksheet: excel A1:9B1: =(A7-A1)/(ROW(A7)-ROW(A1))A2: =A1+$B$1A3:A4:A5:A6:A7:11 Select cells A2:A6. On the Edit menu, point to Fill, and then click Down. The formula is ...

So, the simple formula for interpolation is: y = y1 + (x – x1) * (y2 – y1) / (x2 – x1) Where: x1andx2are the known values of the independent variable that represent the unknown value of x that needs a functional value. ...
The FORECAST.LINEAR function is a powerful tool in Excel that can be used for interpolation. To use this function, first, organize your data into two columns with known values. Next, select the cell where you want the interpolated value to appear and use the formula =FORECAST.LINEAR(x, kno...

For y2, the formula is: =INDEX(C5:C10,MATCH(F3,B5:B10,1)+1) Finally, use the FORECAST function as described above to return the estimated value of y: =FORECAST(F3,F6:F7,F4:F5) How to Interpolate in Excel with the Interpolation Formula ...
