See if this formula does what you want...

=IF(A1<1,0.05,IF(A1<10,0.1,IF(A1<40,1,IF(A1<100,5, IF(A1<400,10,IF(A1<1000,50,100))))))

Note: You end points overlapped (for example, 40 appeared in two test
conditions), so you may want to change my < to <= if I guessed wrong as to
which range you actually wanted them in.

Can you explain what you mean by "nest it for 7 iterations"?
