And some things need to be done regardless of popularity votes. Like fixing decades old bugs like in DATEDIF, and providing matching names between VBA and WorkBook Functions. And providing certain basic Basic functions like max and min. Really.

Thanks for the suggestion, and thanks for showing how you’re using the FORECAST as a workaround. We’ll consider this request along with all the other ideas here and prioritize it according to the votes – so please keep voting if you want to see the priority raised!
Best,
John [MS XL]Brian Canes commentedMaybe have a more general interpolation  Linear, 2nd degree polynomial, third.... and also extrapolation. I have the workaround based on the LINEST function as follows. Define names n, k and m.
'unY=Sumproduct(unX^(n+1m),LINEST(y,x^k))
'where m=TRANSPOSE(ROW(INDIRECT("1:"&(n+1))))
'where k=TRANSPOSE(ROW(INDIRECT("1:"&n)))
'x is array or range of known x's
'ys array or range of known y's
So n=1 is linear, etc
'n is number of terms in polynomial 0<n<16
'unX is unknown x argument
'unY is unknown y to be determined
So for n=1 =SUMPRODUCT(15^(n+1m),LINEST({75000;25000},{10;20}^k)) gives 50000
and =SUMPRODUCT(5^(n+1m),LINEST({75000;25000},{10;20}^k)) gives 100000
Powerful

And while you look at data validation distinguish between text and numbers by doing the usual excel thing in the dv dropdown by justifying numbers right and text left.
