flowchart symbol meaning Algorithm and flowchart: definitions, symbols, examples (2025)

When it comes to creating flowcharts, understanding the meaning of each symbol is crucial for effective communication and problem-solving. As someone who has worked with flowcharts for a while, I've come to appreciate the importance of using the right symbols to convey my ideas. In this post, I'll break down the most common flowchart symbols and their meanings, so you can create your own flowcharts with confidence.

1. Oval: Terminator

The oval symbol, also known as the terminator, is used to represent the starting or ending point of a flowchart. It's usually labeled with a descriptive phrase, such as "Start" or "End," to indicate the beginning or conclusion of a process. The oval symbol is a great way to define the boundaries of your flowchart and provide context for the reader.

2. Rectangle: Process

The rectangle symbol represents a process or an action that needs to be performed. It's often labeled with a verb or a phrase that describes the activity, such as "Calculate" or "Validate Input." The rectangle symbol is a fundamental building block of flowcharts, as it helps to break down complex processes into manageable steps.

3. Rhombus: Decision

The rhombus symbol, also known as the diamond, represents a decision or a conditional statement. It's used to indicate a point in the flowchart where a choice needs to be made, based on certain conditions or criteria. The rhombus symbol is usually labeled with a question or a statement that requires a yes or no answer.

4. Parallelogram: Input/Output

The parallelogram symbol represents input or output operations, such as reading data from a file or displaying output on a screen. It's often labeled with a descriptive phrase, such as "Read Data" or "Print Report." The parallelogram symbol is useful for highlighting the interactions between a process and its environment.

5. Arrow: Flowline

The arrow symbol, also known as the flowline, represents the flow of control or the direction of a process. It's used to connect different symbols in a flowchart, indicating the sequence of steps or the flow of activities. The arrow symbol is essential for creating a clear and logical flowchart that's easy to follow.

6. Circle: Connector

The circle symbol, also known as the connector, is used to connect two or more flowcharts or to indicate a jump to another part of the flowchart. It's often labeled with a reference number or a descriptive phrase, such as "Go to Step 3." The circle symbol is useful for creating complex flowcharts that span multiple pages or diagrams.

7. Loop: Repeat

The loop symbol, also known as the repeat symbol, represents a loop or a repetition of a process. It's used to indicate that a sequence of steps needs to be repeated, either a fixed number of times or until a certain condition is met. The loop symbol is useful for modeling iterative processes or recursive algorithms.

8. Document: Data

The document symbol represents a data file or a document that's used as input or output in a process. It's often labeled with a descriptive phrase, such as "Customer Database" or "Invoice Template." The document symbol is useful for highlighting the role of data in a process and the interactions between different data sources.

9. Manual Input: Manual Operation

The manual input symbol represents a manual operation or a step that requires human intervention. It's often labeled with a descriptive phrase, such as "Enter Customer Data" or "Verify Signature." The manual input symbol is useful for highlighting the points in a process where human input or judgment is required.

10. Predefined Process: Subroutine

The predefined process symbol represents a subroutine or a pre-defined process that's used in a larger flowchart. It's often labeled with a descriptive phrase, such as "Calculate Tax" or "Validate Address." The predefined process symbol is useful for breaking down complex processes into smaller, reusable modules that can be easily integrated into larger flowcharts.
