Cross Object Formula Field in Salesforce

What You’ll Learn

S2 Labs

Imagine if information from your Accounts, Opportunities, Contacts, and Products seamlessly flows together, automatically calculating and displaying right at your fingertips. That’s the magic of Cross-Object Formula Fields in Salesforce.

These dynamic fields act as data bridges, pulling information from related objects and presenting it in a single, unified field. Think of it like a custom calculator that uses data from other objects to generate the results you need.

Let’s find out more about cross-object formula fields in Salesforce and how they work.

What is the Cross Object Formula Field in Salesforce? 

A formula that merges fields on two related objects and spans them is known as a cross-object formula. Suppose an object is on the detail side of a master-detail connection.

In that case, a cross-object formula may reference merge fields from a master (“parent”) object. Lookup relationships can also be used with a cross-object formula.

In Salesforce, a cross-object formula field allows you to automatically calculate and display data from multiple related objects within a single field. It acts as a bridge, pulling information from other objects and presenting it within the current object you’re working with.

Here are some critical characteristics of cross-object formula fields:


Cross Object Formula Field in Salesforce uses merge fields to access data from related objects through established lookup relationships. You can perform various calculations on the referenced data, including arithmetic, logical, and text-based operations. They can also return different data types like currency, date, number, or text, depending on the referenced fields and calculations.


  • It provides increased efficiency as it automatically calculates data, eliminating the need for manual calculations and data entry in multiple locations.
  • Reduces errors by eliminating manual data manipulation and ensuring consistency across objects.
  • Provides consolidated information from related objects in a single place, leading to better decision-making.
  • Flexible calculations allow you to tailor the field to specific business needs and requirements.

Use cases

  • Calculate discounts based on customer data: Pull annual revenue from the Account object and calculate a discount percentage for the Opportunity object.
  • Display combined inventory levels: Sum inventory quantities from various product-related objects for a complete picture. Automate lead scoring: Evaluate lead data from different sources and assign a score based on criteria.
  • Create dynamic text fields: Combine text from different fields across objects to generate personalized messages or labels.


  • Security: Requires appropriate field-level security settings to ensure data access control.
  • Performance: Complex calculations or referencing large datasets can impact page load times.
  • Formula limitations: Subject to Salesforce formula syntax and functionality restrictions.

How to Create a Cross-Object Formula Field in Salesforce?

You can follow the following steps to create a cross-object formula field in Salesforce successfully.

Navigate to Setup:

Go to Setup > Object Manager.

Choose the object and field location:

  1. Select the object where you want to create the cross-object formula field.
  2. Click on Fields & Relationships.
  3. Click on New.

Configure the field details:

  1. Choose Formula as the data type.
  2. Enter a Field Label and Field Name.
  3. Select the Formula Return Type that matches the desired output (e.g., Currency, Number, Text).

Build the Formula:

  1. Click on Advanced Formula.
  2. Use the Insert Field button to select fields from related objects through lookup relationships.
  3. Use operators and functions to perform calculations or manipulations.
  4. Check the syntax using the Check Syntax button before saving.

Access and visibility:

  1. Set the Field-Level Security to control user access to the field.
  2. Choose which Page Layouts should display the field.

Cross-Object Formula Salesforce Example

Let’s consider a scenario where you want to calculate the total value of opportunities associated with an account. You can create a Cross-Object Formula Field on the Account object to sum the values from related Opportunity records.

IF(ISBLANK(RelatedOpportunities), 0, 
SUM(RelatedOpportunities, Amount))

Things To Remember

  • Cross cross-object Formula Field can only be created on many sides.
  • Fields can be referred up to 10 relationships away.
  • We can’t reference cross-object formula fields in roll-up summary fields and when creating default values.
  • We can use the formula field in the validation rule.

Remember, effectively using cross-object formula fields requires understanding relationships between objects, data types, and formula syntax. If you’re unsure about implementing them, consulting with a Salesforce administrator or developer is recommended.
