As you track your projects in Notion, visual progress bars offer a quick snapshot of your progress, an aesthetic enhancement, and a subtle source of motivation. By pairing creative characters with a few Notion functions, you can create beautiful, inspiring progress bars to bolster your workspaces.

The Functions

To create your progress bars, you’ll use the three below functions. If you’re new to formulas, consider starting with Meet Notion’s Formula Property.

slice()

The slice() function returns a segment of a provided text string. It takes three arguments:
  1. The original string
  1. The starting point, where the first character is 0.
  1. The ending point (optional).
Example: slice( "Into the ocean.", 9, 14 ) → "ocean"

if()

The if() function allows you to perform an action if a condition is met, or another action if the condition is unmet. By nesting if() functions, or placing them within one another, you can specify actions for numerous conditions.
The if() function takes three arguments:
  1. The test expression, which evaluates to true or false.
  1. The operation to perform if true.
  1. The operation to perform if false.
Example: if( 2 < 3, "Yes", "No" ) → "Yes"

Comparison Operators

For the first argument — the test expression — you can use comparison functions, such as test() or comparison operators, which you’ll find in The Notion Formula Cheat Sheet.

round()

The round() function rounds the provided decimal number to the nearest integer.
Example: round( 3.2 ) → 3

format()

The format() function converts a provided number to a text string.
Example: format( 20 ) → "20"

Your Percentage Property

To visualize your progress, you first need to calculate it as a percentage within an independent property. You have many ways of doing so; here are two:

Completed Units vs. Total Units

For each project in your database, you might have a property for total units required for completion, then another property for currently completed units.
For example, a school photographer might have a database of classes, with properties for Total Students and Completed Students.
In a Progress (Percentage) property, you can divide the completed units by the total units:
prop( "Completed Students" ) / prop( "Total Students" )

Rollup

If you follow the Bulletproof Workspace methodology your Projects database is linked to your Tasks database. Therefore, you can add a Rollup property that automatically calculates the percentage of tasks completed for the project:
  • Add the Rollup property.
  • Choose your Tasks database.
  • Choose the Checkbox field that indicates the task is complete.
  • Within Calculate, choose Percentage checked.

Your Creative Characters

Your progress bar will include creative characters to represent completed and uncompleted segments of your bar. Here are a few you might consider:
  • Stars → ★☆
  • Circles → ●○
  • Shades → ▓░

Create Your Progress Bar

With your Progress (Percent) property created and your creative characters determined, you’re ready to create your progress bar. Create a new Formula property, name it Progress, then add this formula:
slice("★★★★★★★★★★", 0, round(prop("Progress (Percent)") * 10)) + slice("☆☆☆☆☆☆☆☆☆☆", 0, round((1 - prop("Progress (Percent)")) * 10)) + " " + if(prop("Completed Units") == 0, "0", format(round(prop("Progress (Percent)") * 100))) + "%"

How It Works

Display Solid Stars

The formula starts by determining the number of solid stars to display:
  • It uses the slice() function, where the initial string is ten solid stars.
  • The starting point is 0.
  • For the end point, it multiplies the percentage by 10 to provide a decimal number between 1 and 10. It then rounds that decimal using the round() function.

Add Empty Stars

  • The formula takes the same approach with the empty stars, but it subtracts the percentage from 1.
  • To append it to the solid stars, it uses the concatenation operator (+)

Display the Numeric Percentage

Because your creative characters form a text string, the appended percentage also needs to be a string.
  • If Completed Units is 0, the formula returns "0" (a string).
  • Otherwise:
    • It multiples the percentage by 100 to return a number between 1 and 100.
    • It then uses round() to eliminate any decimals.
    • Then, the format() function converts it to a string.
  • Finally, the concatenation operator adds the % character.
