Challenger banks: cost to income ratio in the UK 2018, by bank
The cost to income ratio (C/I ratio) is an important financial metric in determining the profitability of banks. The measure looks at the cost of running operations as compared to a bank’s operating income. Lower ratios mean that a bank is running more profitably whereas a higher C/I ratio indicates the bank's operating expenses are too high. As of the third quarter of 2019, the average cost to income ratio in Great Britain was 60.1 percent.
