iPhone 18 Pro系列買空機還是綁約划算?先看自己原先的月租費

Quick Look

蘋果iPhone 18 Pro系列於9月18日開賣,3C達人Tim哥指出,判斷買空機或電信綁約是否划算,關鍵在於原本的月租費。以256GB版為例,空機售價44,900元,綁約36個月專案價26,300元。若原月租599元升至1,399元,實際購機成本達55,100元,反而比空機多花10,200元;若原月租999元或以上,綁約則可能省下數千元。文章提醒需將月租差額計入購機成本,並指出舊換新、折扣等優惠可能影響最終價格。

Why It Matters

蘋果iPhone 18 Pro系列於9月18日正式開賣,消費者常見困惑為是選擇買空機較划算,還是透過電信綁約獲得較低手機價格。文章引用3C達人Tim哥的購機成本算法,強調需將月租差額計入總成本。

蘋果iPhone 18 Pro系列本週五9月18日正式開賣,不少人會陷入買空機還是電信綁約比較划算,3C達人Tim哥教你算這筆帳。

手機便宜不等於真的省 先把月租差額算進去

Tim哥先前影片曾分享一套簡單算法:「購機真實成本=手機專案價+(新月租-原月租)×合約月數。」簡單來說,如果為了拿到較低的手機價格,得把原本的月租往上拉,多繳的月租其實也應該算進購機成本。

請繼續往下閱讀...

以今年iPhone 18 Pro 256GB為例,蘋果空機售價44,900元。三大電信月租1,399元、綁約36個月的手機專案價都是26,300元。

如果本來就是1,399元用戶,算法最單純,因為月租沒有增加,實際購機成本就是26,300元,和44,900元空機相比,等於省下18,600元。

599元升1,399元看似省 算完反而多花萬元

但如果原本只使用599元方案,升級到1,399元後,每個月就得多付800元,36個月累計多出28,800元,再加上26,300元手機專案價,實際購機成本變成55,100元,反而比44,900元空機多花10,200元。

換成原本月租999元的用戶,情況就不一樣。從999元升到1,399元,每個月多400元,36個月共增加14,400元,加上26,300元手機專案價後,實際成本為40,700元,仍比直接買44,900元空機省4,200元。

也就是說,同樣是月租1,399元、綁約36個月,對不同用戶來說,結果可能完全相反。如果原本使用599元低月租,為了拿26,300元的手機專案價升級方案,最後反而可能比空機多花超過1萬元;但原本就是999元或1,399元用戶,綁約就相對容易顯得划算。

如果進一步反推,以iPhone 18 Pro 256GB空機44,900元、專案價26,300元來算,36個月期間可容許的額外月租總成本為18,600元,平均每月約517元。換句話說,原本月租大約要在882元以上,升到1,399元後的整體成本才不會高於買空機。

空機還是綁約?關鍵其實是你原本月租多少

因此可以簡單理解為:原本999元以上用戶,升到1,399元比較有機會比買空機省;599、799元低月租族則要先算清楚。因此到底選空機還是綁約,真正影響結果的往往不是哪一家電信便宜幾百元,而是你原本的月租到底是多少。

實際購機時還有舊換新、VIP折扣、信用卡回饋及加值服務等優惠,最後價格可能再往下壓。不過,如果只是單純比較「空機」和「電信綁約」,先把原本月租和升級後多出的費用算進去,會比只看手機專案價更準。
