Referral Rock

Referral fee calculator

Work out what one referral fee should be. Flat, percentage, or a mix for each side, then check what the whole program returns after reward costs. Results update as you type.

How to use the calculator

1

Set the rewards

Choose a flat amount or a percentage for each side, the person who refers and their friend. Mixing the two works fine.

2

Enter your numbers

What the friend spends, or the monthly price for subscriptions, and what a customer is worth to you in total. Blank fields count as zero.

The cost per referral and what you keep update as you type, with the whole program's return in the calculator below.

Percentage or flat fee?

A percentage fee scales with deal size, which suits businesses where deals vary a lot. A flat fee is easier to promote and budget, and works well when deal sizes are predictable. Many programs start flat and move to a percentage once the numbers prove out.

The calculator makes the trade-off concrete. Run the same referral volume through both models and compare what you'd pay and what margin is left before committing to either.

Set a flat amount or a percentage for each side, including a mix of the two. Percentages apply to what the friend spends, once or per month for subscriptions. There's also a mode that suggests a fee from customer lifetime value, which is revenue per customer minus acquisition cost.
A referral fee usually rewards someone with an existing relationship to the customer they send, like a happy client. A finder's fee rewards a third party for making an introduction, often in one-off or higher-value deals. There's a separate finder's fee calculator on this site for that model.
Referral programs often reward two people, the member who shared and the new customer who joined, so the calculator adds both costs. Affiliates earn a single commission, which the affiliate commission calculator handles.
