What is Fast Formula?

Fast Formula is a simple way to write formulas using English words and basic mathematical functions to define business rules in Oracle HCM. It is a powerful and flexible tool that can tailor the application to meet specific business requirements without custom programming.

How does it work?

Fast Formulas are written in a proprietary language developed by Oracle. They can reference database items, perform loops, and make decisions with IF statements, among other functionalities. The formulas can be as simple as calculating a date difference or as complex as determining eligibility for benefits based on many factors.

Usage of Fast Formula in Fusion HCM

Oracle Payroll Fast Formula is used across various modules to handle complex calculations and business logic. Here are some of the key areas where Fast Formula is utilized:

In Payroll:

  • Calculating earnings and deductions
  • Determining tax withholdings
  • Processing payroll for different groups of employees

In Benefits:

  • Determining eligibility for different benefit plans
  • Calculating employer contributions
  • Managing enrollment periods and rules

In Compensation:

  • Calculating bonuses and commissions
  • Driving salary increases and adjustments
  • Implementing compensation rules and guidelines

Absence Management:

  • Calculating leave accruals
  • Determining eligibility for leave types
  • Managing absence payments

Oracle Fast Formula Examples

Below are some simple Oracle fast formula examples

  1. Payroll Calculation for Overtime


/* Define the overtime rate as 1.5 times the standard rate */





/* Calculate overtime hours */



/* Ensure we do not have negative overtime hours */




/* Calculate overtime pay */


/* Return the overtime pay */


  1. Transformation Fast Formula for Data Load

/* Fast Formula for transforming a data format during data load */


/* Convert the date from DD-MM-YYYY to YYYY-MM-DD format */



/* Return the transformed date */


These are some Sample Fast formulas in Oracle Fusion HCM. If you take up a course in Oracle Fusion HCM, you will learn about these in further detail. 

Case Study: Fusion Payroll: How to Create and Modify a Fast Formula

Creating a Fast Formula:

  • Identify the Requirement: Understand what you need the formula to do. For example, calculate overtime pay for employees.
  • Define the Inputs: Determine what inputs are needed for the calculation, such as hours worked and overtime rates.
  • Write the Formula: Using the Fast Formula language, write the formula logic. This will include defining variables, writing calculations, and setting up any necessary conditions.
  • Test the Formula: Before deploying, test the formula to ensure it calculates correctly in all expected scenarios.

Modifying a Fast Formula:

  • Understand the Existing Logic: Before making changes, it’s crucial to understand the current logic and what each part of the formula does.
  • Make the Changes: Carefully make the required changes, ensuring you do not disrupt the existing logic unless necessary.
  • Test Thoroughly: After changes, test the formula extensively to ensure that it still works as expected and that the new modifications produce the correct outcomes.

Best Practices:

  • Comment your formulas to explain complex logic.
  • Keep formulas as simple as possible.
  • Reuse formulas when possible to maintain consistency.
  • Regularly review and update formulas as business rules change.

Step By Step Process of Creating Fast Formulas in Oracle Fusion HCM

Page 1: Overview and Initial Setup

Step 1: Accessing Fast Formulas

Log in to your Oracle Fusion HCM instance using your authorized credentials. Once logged in, navigate to the “Setup and Maintenance” work area, the hub for configuring and managing your HR processes.

Step 2: Locate the “Manage Fast Formulas” Task

In the “Setup and Maintenance” work area, use the search bar to locate the task “Manage Fast Formulas.” This task is where you will define, create, and manage your custom Fast Formulas.


Step 3: Initiate Fast Formula Creation

Click on the “Manage Fast Formulas” task to enter the Fast Formulas page. Here, you’ll find various options related to your existing formulas and the ability to create new ones. Click on the “Create” button to start crafting your Fast Formula.

Step 4: Enter Basic Details

Begin by providing a distinctive name for your Fast Formula. This name should be meaningful and relevant to the logic you will define. Additionally, select the appropriate legislative data group and effective date to ensure the formula aligns with applicable regulations and requirements.

Step 5: Choose Context

Select the context that best represents the area of your HR process where the Fast Formula will be applied. The context is where your formula logic will operate, such as payroll, absence, or compensation calculations.

Step 6: Add Input Values

Define the input values required for your Fast Formula. These inputs can include constants, variables, or values from the application. These inputs serve as the building blocks of your formula logic.

Step 7: Craft Formula Logic

This is where the heart of your Fast Formula lies. In the “Formula” section, you’ll write the intricate logic that shapes the behavior of your custom formula. Utilize the special syntax provided by Oracle Fusion HCM to integrate functions, operators, and built-in variables, creating a sophisticated set of rules and calculations.

Step 8: Testing the Formula

Before deploying your Fast Formula in a live environment, it’s crucial to test it thoroughly using sample input values. Use the “Test” button to validate the formula’s accuracy and reliability. This step helps identify and rectify potential errors or miscalculations before they impact HR processes.

Step 9: Save and Activate

After writing, testing, and refining your Fast Formula, save it. If the formula is ready to be put into action, click the “Activate” button to make it active. This step marks the transition from a concept to a functional component of your HR processes.

Step 10: Attach to Relevant Process

Depending on the context you selected earlier, you might need to attach the Fast Formula to a specific process. This ensures that the formula is executed in the correct scenarios, such as during payroll processing or absence accruals.


Step 11: Review Usage and Details

Fast Formulas can have wide-ranging impacts across your HR processes. Use the tool’s built-in functionality to review the formula’s usage and dependencies. This step helps ensure that changes to the formula are made with a comprehensive understanding of its implications.

Step 12: Manage and Maintain

After your Fast Formula is used, you can manage and maintain it as needed. This includes editing the formula, creating clones for variations, or retiring formulas no longer required.

Creating Fast Formulas in Oracle Fusion HCM represents a powerful capability for organizations seeking to tailor their HR processes to their unique requirements. It’s crucial to invest time in thoroughly understanding the logic you’re implementing, testing it rigorously, and maintaining it to ensure the integrity and accuracy of your HR operations. For in-depth guidance and specific syntax, always refer to Oracle’s official documentation or consult with experienced professionals.
