When a loan turns non-performing, the bank must stop booking interest income and set aside provisions against it, hurting profitability. NPAs are classified as sub-standard, doubtful or loss assets. Gross NPA is the total; Net NPA subtracts provisions already made.
Formula
Gross NPA Ratio = Gross NPAs ÷ Gross Advances × 100
Example
A bank with ₹50 crore of NPAs on ₹1,000 crore of loans has a Gross NPA ratio of 5%.
