Cost Recovery Ratio
This is the ratio of fare revenue to total operating costs, and is a key indicator of financial performance.

It may most conveniently be expressed as a percentage. If it equals 100%, the operation as a whole is breaking even; if it exceeds 100% it is earning a surplus, while if it is below 100% the operation is losing money.

Typical cost recovery ratios for a profitable bus operation lie between 110% and 115%.
