calculation not accurate

发帖费 ： 0.15 * 0.8 = 0.12
成交费 ： 0.35 * 0.8 = 0.27 (eBay fee discount)
paypal 费用 ： 0.42 (based on 3%, should be 1.9%) at $0.38 (Paypal volume discount at 1.9% for > 100K/month).

mail: $0.5-0.8 (use first class no tracking), count probability of loss ($0.6 - $1 saving in mail is worth the risk in statistics).

cost of good: $1

Total: $2.27 - $2.5, profit: $1.5/item

Feedback 50K/month, transaction: 50K X 5 = 250K

Net profit/month = $375K

transaction per day 8-9K

# of employees: 15 - 20. salary: $50-60K.

profit after labor: $300K/month

所有跟帖： 

• 月成交量按 feedback x 2.5 计算大概更接近实际。如此的话， -乐也思蜀- ♂ (26 bytes) () 02/11/2010 postreply 03:46:58

• First-Class Mail Package 不会只有 0.5 -0.8 吧？ $1.5 左右吧 -younghl- ♂ (0 bytes) () 02/11/2010 postreply 04:52:22
