Help with a Crystal Report to determine Percentage change between formula and static value 1

[SBSMedicalTech]

I need help calculating the percentage difference between two fields.

In my report, I have the following formula fields set up:

Est1 Actual %
Est2 Actual %
Est3 Actual %
Est4 Actual %
Est5 Actual %

I also have 5 static percentages for each of these I need to get a percentage difference for:

1 %
20 %
59 %
18 %
2 %

In total, I need 5 new formula fields to determine the percentage difference between a formula field and a static value:

Percent diff between "Est1 Actual %" and "1 %"
Percent diff between "Est2 Actual %" and "20 %"
Percent diff between "Est3 Actual %" and "59 %"
Percent diff between "Est4 Actual %" and "18 %"
Percent diff between "Est5 Actual %" and "2 %

Just create 5 more formula

eg
@Est1 Diff
1- {@Est1 Actual %}

Repeat for others
