CALCULATE YOUR DAILY INCOME AND EXPENSE

Daily Income:
[(# of rented refs clicks) x (ref earnings per click)]
+
[(# of direct refs clicks) x (ref earnings per click)]
+
[(# of your clicks) x (your earnings per click)]
=Total Income
Daily Expense:
[(days renewing) / 30 x (1 - discount%) x (cost of 1 ref per month)
= (answer then needs to be round off to two decimal places)
x
(# of referrals) / (days renewing)]
=(renewing costs of all refs per day)
+
[(total yearly membership cost) / 365]
+
(recycling cost)
=Total Expense
Net Profit = (total income) - (total expense)

For example renewing 240 days with 325 refs
with a 0.7 avg (325x0.7=227.5 clicks)
and 150 clicks from direct refs:
Daily income:
(227.5 clicks x 0.01)
+
(150 clicks x 0.01)
+
(9 clicks x 0.01)
Total income = $3.865
Daily expense:
[240 / 30 x (1 - 0.30) x 0.21
= 1.18 (rounded to two decimal places)
x
(325/240)]
Renewing cost = $1.598
+
(90/365)
+
(recycle cost)
Total expense = $1.844
Daily Net Profit = $2.021
