# Pricing and plans
Function Junction uses usage-based pricing, where your monthly fee depends on the revenue generated over time from orders attributed to active campaigns.
Only purchases tied to a Function Junction campaign count toward your monthly fee. Orders on products without an active campaign are excluded.

## Pricing and plan overview
Your fee is calculated based on monthly campaign-attributed revenue (order value plus any discount applied through a campaign) month-over-month. Fees increase by $50 in the first two tiers, and then in $100 increments, up to a $900/month maximum.
Order attributed revenue bandwidth also increases as you scale up, giving you a greater return on investment.

## How attribution works
Function Junction uses order attribution to determine your monthly fee. Only orders where a campaign function was actively applied at checkout count as attributed orders, and their sales value contributes to attributed revenue.
Your monthly fee is then calculated based total attributed revenue. All attributed orders are also automatically tagged in Shopify with `function junction`, so you can easily see which purchases were driven by your campaigns. Learn more about [Order tags](/account-management/order-tags.md).
**Example:**
If 500 customers trigger a campaign discount with their purchases in one month, and their combined order value is $50,000, then that $50,000 is counted toward your attributed revenue for the month and goes toward the calculation of your plan tier.

## Downgrading your plan
