大家好,最近為了弄清楚街口幣的回饋機制究竟怎麼計算,
在7-11實驗了幾次,得出了一點心得,希望能幫到大家。
本篇是用電腦完成的,建議以電腦模式觀看。
下文情況皆是街口綁定台新銀行帳戶,於7-11消費試算而成。
(一)消費金額與回饋率:
先講結論:
花25元回饋率最高,會到8%,
花50-74元,可以考慮分兩單,還可以多拿一張發票
花75元,回饋率會到6%,是第二個高峰
-----------------------------------
-----------------------------------
| 定義表 |
| |
| 消費金額:商家優惠&折抵街口幣後的消費金額,不含當次回饋的街口幣 |
| |
| |
| |
| |
| 回饋率:當次回饋的街口幣/消費金額 |
| |
-----------------------------------
7-11若使用街口支付可獲得的街口幣回饋率,依照街口支付app上所述,最高為4%,
4%之中包含兩項,分別是:
1. 街口支付提供的2%街口幣回饋
2. 街口支付綁定銀行帳戶提供的2%街口幣回饋
就我觀察,實際回饋的街口幣採取分項計算,皆四捨五入,算法如下:
實際回饋街口幣 = 消費金額*2% + 消費金額*2% (四捨五入)
我實測在7-11使用街口消費25塊,會獲得2元街口幣,而當次消費的回饋率為8%
以下是試算消費金額與回饋率的圖:

可以發現:
消費金額落在25元會將回饋率最大化,是8%
消費金額落在25元會將回饋率最大化,是8%
消費金額到了33塊,回饋率會落在約6%
消費金額到了50塊,回饋率會落在官方聲稱的4%,
消費金額到了74塊,回饋率會落到低點,約2.7%
消費金額到了75塊,回饋率又會提升到6%
因此,若想將街口幣回饋率最大化,應盡可能將消費金額限縮在25元-49元
(二)街口幣折扣金額計算
街口聲稱街口幣最高折抵金額為該次消費總額的30%。
街口幣在折抵時沒辦法自由選擇要折抵幾塊,要就折滿,要就不折
所以要使用街口幣的同時,也能賺取街口幣,是重要的事情
我實測買了一罐35元的飲料,並折抵街口幣,
35*30%=10.5,所以我不確定會折11元還是10元
一次折了11塊,實際消費金額只有24塊,沒賺到半毛街口幣,虧
不過可以猜測街口在處理小數時,應該都採四捨五入,
因此應該多買個袋子或不要折抵,比較划算。
