Estimate customers gained, profit, ROI %, CPA, and payback—based on your referral assumptions.
Tip: set LTV as gross-profit LTV (after COGS). Rewards + software go into “cost”.
Assumptions: LTV reflects expected gross profit per customer over the horizon. Program cost includes rewards paid for successful referrals plus fixed monthly software/ops. Payback assumes gross profit accrues evenly across the horizon.
