Month-by-month (Program B revenue)
How the math works
Each month you refer visitors × CTR × CVR new customers. For recurring programs, every monthly cohort keeps paying commission but decays at your churn rate: month-n revenue = Σ cohorts × price × rate × (1 − churn)age. The 12-month totals let you compare a bounty and a recurring offer on equal footing. Related reading: the churn break-even formula and why EPC beats commission rate.
