Notion’s Formula property offers immense utility, allowing you to manipulate other properties in a variety of useful ways. Formulas can be as simple as `2 + 2`

(literally) or elaborate compilations of nested functions.

The examples below are widely useful yet easy to implement for users at all levels. To demonstrate them, we use two sample databases: a basketball team roster and a list of ecommerce orders. Feel free to duplicate them for your own practice.

As you utilize the Formula property, be sure to reference *The Notion Formula Cheat Sheet*, and send any questions our way on Twitter.

If you’re new to formulas, consider starting with *Meet Notion’s Formula Property* for a fundamental understanding of how they work.

#### What You’ll Learn

**Team Roster**

We’ll begin with a database of players who comprise a basketball team.

*Side note: If you’re a hoops fan, you’ll appreciate The NBA — in Notion.*

### Merge First and Last Names

Given each player’s First Name (`text`

) and Last Name (`text`

), we can create a `Formula`

property that combines them into a Full Name using the `+`

operator:

`prop( "First Name" ) + " " + prop( "Last Name" )`

### Calculate Age

Given each player’s Birthday (`date`

), we can determine their ages with the `dateBetween()`

and `now()`

functions:

`dateBetween( now(), prop( "Birthday" ), "years" )`

### Add Context to Gallery Cards

When we display the roster as a Gallery, some properties stand alone ambiguously without context, such as Age. Using the `concat()`

function, we can add a label to those properties. When we do so, we also need to convert Age (`number`

) to `text`

using the `format()`

function.

`concat( "Age: ", format( prop( "Age" ) ) )`

`concat( "School: ", prop( "School" ) )`

**Ecommerce Orders**

The next set of examples augments a database of orders from an online business. The database contains an item for each unique Order-SKU pairing. For example, Order #1 contains two products (P18 and P21), and therefore has two items in the database: 1-P18 and 1-P21.

### Generate a Unique ID

Databases often need a unique ID for each item. Given the Order # (`number`

) and Product SKU (`text`

), we can generate a unique ID, which we can easily paste into the ID (`title`

) property. Because the Order # is a `number`

, we use the `format()`

function to convert it to a `string`

so it can be merged with the Product SKU (`text`

) using the concatenation operator (`+`

)

`format( prop( "Order #" ) ) + "-" + prop( "Product SKU" )`

### Calculate Markup

*Markup calculations would typically occur in an independent Products database, but for simplicity’s sake, we’ve included them here.*

Say we want our Markup to correlate with the Cost of Goods (`number`

):

- Where Cost of Goods is less than $10, Markup is 25%
- Where Cost of Goods is $10 or more, but less than $50, Markup is 20%
- Where Cost of Goods is $50 or more, Markup is 15%

We can achieve this with nested `if()`

functions:

`if( prop( "Cost of Goods" ) <= 10, .25, if( prop( "Cost of Goods" ) < 50, .2, .15) )`

### Calculate Customer Price

With the Markup determined, we can then calculate Customer Price by multiplying the Cost of Goods (`number`

) by the Markup (`number`

), then adding the Cost of Goods (`number`

):

`prop( "Cost of Goods" ) * prop( "Markup" ) + prop( "Cost of Goods" )`

### Calculate Tax

We then want to calculate tax by multiplying the Customer Price (`number`

) by the Tax Rate (`number`

):

`prop( "Customer Price" ) * prop( "Tax Rate" )`

### Calculate Total Cost

Our store is part of the free-shipping movement, so we can calculate the Total Cost by adding the Customer Price and Tax:

`add( prop( "Customer Price" ), prop( "Tax" ) )`

### Show Days Since Order

For tracking the fulfillment process, we can calculate the Days Since Order using the Order Date (`date`

) and `now()`

function within the `dateBetween()`

function.

`dateBetween( now(), prop( "Order Date" ), "days" )`

### Show Fulfillment Progress

With five different stages of processing each order, we can create a field that nicely indicates Progress. It includes a series of nested `if()`

functions to define an output for each Fulfillment Stage:

`if(prop("Fulfillment Stage") == "Payment Processing", "•◦◦◦◦ 20%", if(prop("Fulfillment Stage") == "Payment Cleared", "••◦◦◦ 40%", if(prop("Fulfillment Stage") == "Packaged", "•••◦◦ 60%", if(prop("Fulfillment Stage") == "Shipped", "••••◦ 80%", if(prop("Fulfillment Stage") == "Delivered", "••••• 100%", "")))))`

### Show Urgency

With properties for Days Since Order (`number`

) and Progress (`text`

), we can establish a field that displays a special character for orders that remain unshipped after a week:

`if( and( contains( prop( "Progress" ), "◦◦" ), prop( "Days Since Order" ) >= 7 ), "?", "" )`

The formula tests if the Progress property contains two or more empty circles ** and** the Days Since Order is seven or more days. If so, it displays an emergency emoji.

We’ve also sorted the table by this Attention property to amplify the urgency.
