The post the fare schedule for each city on their website. e.g. here is Lyft Boston $2.25 + $1.50 per mile and $.30 per minute. It's hard to say what a typical ride is. In my experience Lyft is always cheaper than a Boston cab. UberX is sometimes cheaper as long as surge pricing is not turned on.
Deutsche Bank then used the cost of Uber and Lyft's base non-shared ride offering as a proxy for on-demand mobility, and found that the average was $1.54 per mile in the top 20 metro areas. Deutsche Bank estimates that for options like UberPool, where customers can share the ride with strangers, the cost was an estimated 20%-50% cheaper.
