How can I use an IF function and tell excel that if a number is between a
range, use a certain percentage and if it's between another range, use
another percentage.

For example.

Between 0.01 - 10.00 use 8%
Between 10.01 - 20.00 use 8.25%
Between 20.01 - infinite use 9%


IF(A120.01,9%*A1,IF(A110.01,8.25%*A1,IF(A10.01, 8%*A1,0)))
