A minimum per-trip payment is added to any ride originating in NYC in which the total fare did not meet the minimum fare per the TLC's guidelines.
The minimum per-trip payment formula will have varying rates depending on the route:
Miles and minutes within NYC:
($1.088 x Trip Miles) + ($0.495 x Trip Minutes)
Miles and minutes outside NYC:
($1.262 x Trip miles) + ($0.574 x Trip minutes)
Taxes and commission are already accounted for in the minimum per-trip payment amount. High Demand, Paid Wait Time payments and if applicable, any long pick-up bonus are included in the calculation. Tolls, tips, and promotions are excluded.
