港鐵車費主要以「可加可減」機制調整票價，而根據政府統計處最新公布的數字，港鐵在可加可減調整機制下，預料2021/22年度需減價1.7％，是可加可減機制生效以來首次錄得減幅。
今日（3月29日）統計處公布去年第四季運輸業名義工資指數，變幅為-1.5％。而代入方程式並進行計算後，港鐵2021/22年度需減價1.7％，是可加可減機制生效以來首次錄得減幅。
港鐵車票根據「可加可減」機制調整，機制以一條方程式計算票價的調整幅度。方程式為：「整體的票價調整幅度 = (綜合消費物價指數變動x0.5 + 運輸業工資指數變動x0.5)– 生產力因素（0.6%）」
而港鐵的票價亦受方程式的「封頂」機制影響，港鐵每年加價不可高於「家庭每月入息中位數」，以確保市民負擔能負擔車票價錢。
是次演算為港鐵自實行「可加可減機制」後，首次錄得減價結果，港鐵宣布6月27日起將車票減價1.7%。而回顧2016至2020年的票價，實際加幅為+2.65%、0%、+3.14%、+3.3%及0%。
而港鐵早前推出的車費8折優惠將於本月底到期，港鐵宣布將改推車費95折優惠，優惠活動將於4月1日起生效。
