FAQ
How does referral ROI calculator work?
The calculator combines job value, margin, LTV, repeat behavior, conversion assumptions, and churn to compare referral gains against referral investment costs such as incentives, send costs, and follow-up effort.
What is a good referral reward rate?
A common starting point is to keep reward cost inside a protected share of gross profit per converted referred customer, then adjust based on conversion quality and margin.
Why include churn and repeat purchase rates?
Referral value is not just first purchase value. Retention and repeat behavior significantly affect total customer value and safe reward ceilings.
Can I use this calculator before launching automation?
Yes. The model helps define guardrails before launch so your reward strategy and campaign targets are margin-aware from day one.
How often should ROI assumptions be updated?
Review assumptions monthly or after major pricing, margin, or conversion changes so the model reflects current operating reality.
