Hi,

May be..

=IFERROR(SUMPRODUCT(--(A36>=A12:A33),C12:C33)+(INDEX(C12:C33,MATCH(A36,A12:A3 3)+1)/(INDEX(A12:A33,MATCH(A36,A12:A33)+1)-INDEX(A12:A33,MATCH(A36,A12:A33)))*(A36-INDEX(A12:A33,MATCH(A36,A12:A33)))),SUM(C12:C33))

HTH

Hello, Try this,

=IFERROR(SUMIF(A12:A33,"<="&A36,C12:C33)+(INDEX(C12:C33,MATCH(A36,A12:A33,1)+1 )/(INDEX(A12:A33,MATCH(A36,A12:A33,1)+1)-LOOKUP(A36,A12:A33)))*(A36-LOOKUP(A36,A12:A33)),SUM(C12:C33))
