Set up a 2-column table somewhere like this:

0 0
51 0.05
201 0.1
501 0.2

and so on for your other values. Suppose this occupies cells X1 to Y8.

Then you can use this formula:

=VLOOKUP(D1,X$1:Y$8,2)

to return the appropriate factor depending on the value in D1. Copy
down as required.

Hope this helps.

Thank you!
