ROI = (profit from referred customers minus reward cost) divided by reward cost. Referrals tend to be high value because they arrive pre-trusted. As long as the profit per referred customer comfortably exceeds the reward, the program pays.

Why referrals usually pay

A referral reward is one of the cheaper ways to grow, because the customer arrives already trusting you, on the word of someone they know. They tend to convert better and stay longer than a stranger from an advert.

The program pays as long as the profit from a referred customer comfortably beats the reward you pay for them. This calculator confirms whether your numbers work and how much room you have to make the reward more attractive.

Frequently asked questions

How do I measure referral program ROI?

Subtract the total reward cost from the profit generated by referred customers, divide by the reward cost, and multiply by 100. As long as profit per referred customer beats the reward, the program pays.

Why are referred customers valuable?

They arrive pre-trusted on the recommendation of someone they know, so they tend to convert better and stay longer than customers won from cold advertising.

How big should the reward be?

Large enough to motivate referrals but well below the profit a referred customer brings. The gap between the reward and the customer value is your margin on the program.

Should I reward both sides?

Rewarding both the referrer and the new customer often works well, since it gives both a reason to act. Just keep the combined reward below the profit the new customer generates.
