Morphology
The meaning is directly compositional: 'rate' denotes speed or amount per unit and 'attrition' denotes a gradual decrease, so 'rate of attrition' straightforwardly means the speed at which something decreases. This construction (noun phrase with 'rate of' + noun) is a common, cross-linguistically transparent pattern, so a B1 learner who knows the constituent words can readily infer the MWE meaning.
Etymology
Rate of attrition comes from the image of something slowly wearing away, like stones rubbed down by a river. Here attrition is the wearing away and rate is how fast it happens, so the phrase means 'the speed at which something decreases'.
