To extract the numeric values from an alpha numeric text, use any of the following array formulas

{=SUM(MID(0&A1,LARGE(ISNUMBER(MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1)/1)*ROW(INDIRECT("1:"&LEN(A1))),ROW(INDIRECT("1:"&LEN(A1))))+1,1)*10^(ROW(INDIRECT("1:"&LEN(A1)))-1))}

OR

{=SUM(IFERROR(MID(A1,LARGE(ISNUMBER(MID(A1,ROW(IND IRECT("1:"&LEN(A1))),1)^0)*ROW(INDIRECT("1:"&LEN(A1))),ROW(INDIRECT("1:"&LEN(A1)))),1),0)*(1&REPT("0",(ROW(INDIRECT("1:"&LEN(A1)))-1))))}
