Percentage Remaining
Subtract what is used from the total, then divide by the total. Handy for data plans, ink, annual leave — anything where the question is “how much is left”.

Formula
Left = (Whole − Used) ÷ Whole × 100
If usage exceeds the total the remainder is held at zero; a negative balance is meaningless, so track the overage separately.
