The precision of the Variable Pay calculations are highly dependent on the number formats you choose, because many of the results are the product of several calculations. SAP SuccessFactors Variable Pay module rounds at each step of the calculation.
Number Formats are configured during the initial implementation and not generally changed after implementation. Default and rules created during implementation populate in the Number Formatting Rules List.
If the standard formats do not meet your needs, you can create additional number formatting rules in Plan setup→Set Number Format Rules.

Number format rule determines how numbers will be displayed based on what type of field the number is being used for:
- Money
- Percent
- Amount
- Rating
- Ratio Value – applicable to comp-ratio display
- Proration – applicable to date-based proration
Number Format Parameters
- Rule name: Unique string value id
- Format: Determines how significant and non-significant digits are displayed
- Use For: Specify the type of number field
- Mode: Determines if the numbers will be rounded or truncated
- Multiple: Determines the rounding behavior. Can be rounded to increments of 10, 100, 1000 etc.
Note
- Compensation templates allow number formatting to be defined at Field Type level (e.g. money type, percent type, etc.) while Variable pay templates allow for column-level number format (e.g. one money field can use standard money format, another money field can have a custom number format).
- The system calculates and stores percent type fields as a real number, for example, 90% is stored as 0.90, and not as a whole number unlike in compensation where 90% is stored as 90.
If you need a certain field to use a different format than the default, you can assign a different format in Design Worksheet→Set Number Formats.

Note
Number formats are not generally changed after implementation.
New number formats should be thoroughly tested as it may cause forms not to launch successfully.
