What Are the Formulas in Google Sheets? A Practical Guide
Learn what the formulas in Google Sheets are, how to write them, and practical examples for sums, lookups, and text tricks. A technical, step-by-step guide for students and professionals.
In Google Sheets, formulas are expressions you type into a cell to perform calculations, reference other cells, or manipulate data. A formula always starts with an equals sign (=) and can combine operators, functions, and cell references to produce dynamic results. Common examples include SUM, AVERAGE, VLOOKUP, and IF, which expand your spreadsheet capabilities.
What are the formulas in Google Sheets?
If you’re answering what are the formulas in google sheets, they are expressions that start with = and perform calculations, reference other cells, or transform data. In practice, a formula can add numbers, join text, search for a value, or compute dates. Each formula combines operators, constants, cell references, and functions to produce a result that updates automatically when inputs change. The most common functions include SUM, AVERAGE, IF, and VLOOKUP, but Google Sheets supports hundreds of specialized functions for text, date handling, arrays, and analytics. A good formula is readable, uses relative and absolute references appropriately, and avoids hard-coded constants scattered through a sheet. According to How To Sheets, clear, well-documented formulas pay dividends in accuracy and collaboration. In the examples below, you’ll see the basics in action and how to extend them to real-world tasks.

Steps
Estimated time: 15-25 minutes
- 1
Plan data layout and formula targets
Review your data columns and decide which cells will hold formulas. Sketch a simple mapping of inputs, outputs, and references so you can keep formulas readable and maintainable.
Tip: Label your output cells clearly and consider named ranges for long formulas. - 2
Enter the first formula in a cell
In a blank cell, type = followed by the formula that uses your chosen function and references. Start with a simple example to verify behavior.
Tip: Use a small data sample to validate accuracy before expanding to the full range. - 3
Copy or fill the formula to adjacent cells
Drag the fill handle or use copy/paste to propagate the formula. Choose relative vs absolute references carefully to ensure correct results when moved.
Tip: When copying, test a couple of cells in different rows to confirm references adjust as intended. - 4
Introduce absolute references where needed
Lock certain references with $ (e.g., $A$1) to keep anchors fixed while other references adjust with fill operations.
Tip: Use absolute references for constants or lookups you don’t want to shift. - 5
Add error handling
Wrap risky calculations with IFERROR or ISERROR to present friendly messages instead of raw errors.
Tip: Plan user-friendly fallbacks to improve resilience. - 6
Audit and optimize
Review formulas for redundancy, consider ARRAYFORMULA or QUERY for efficiency, and comment complex logic where possible.
Tip: Comment in the sheet (using notes) to explain non-obvious parts.

FAQ
What is a formula vs. a function in Google Sheets?
In Sheets, a formula is an expression that computes a value. A function is a predefined operation you call within a formula, like SUM or IF. You combine functions and references to build powerful, dynamic calculations.
A formula calculates something using functions and references. Think of functions as built-in tools within your formula.
How do I sum a column in Google Sheets?
To sum a column, use a formula like =SUM(A:A) or =SUM(A1:A100). The range should cover all cells you want to include. You can adjust the range as data grows.
Use SUM with the column range, and extend it as your data grows.
How can I fix common errors like #REF! or #VALUE!?
#REF! usually means a referenced cell was deleted or moved. #VALUE! often indicates wrong data types. Check your references, ensure ranges exist, and consider wrapping calculations in IFERROR to provide friendly messages.
Check your references and data types; use IFERROR to handle unexpected results.
Can I run formulas across multiple sheets?
Yes. You can reference cells on other sheets with SheetName!Cell. For example, =SUM(Sheet2!A1:A10). Be mindful of data organization to avoid circular references.
Yes, you can pull data from other sheets with SheetName!Cell and manage it carefully.
What’s a good starting point for learning Google Sheets formulas?
Start with basics like SUM, AVERAGE, and IF, then gradually add lookups (VLOOKUP/INDEX-MATCH) and text functions. Practice on a small dataset and gradually scale up.
Begin with simple functions, then build up to lookups and text handling.
The Essentials
- Master basic formula syntax to unlock Google Sheets power
- Use relative/absolute references correctly
- Handle errors gracefully with IFERROR
- Leverage common functions (SUM, IF, VLOOKUP) for real-world tasks
- Audit formulas for readability and performance
