How do you calculate the margin of an Uber or 99 ride?

First the cost per kilometer: fuel price divided by kilometers per liter, plus the maintenance cost per km. Then the net profit: fare received minus (km driven × cost per km).

What goes into a rideshare driver's cost per km?

At minimum fuel and maintenance (oil, tires, service). Drivers who rent the car or pay a loan, insurance and vehicle tax should add those fixed costs spread across the days worked.

How the ride margin is calculated

The platform's app shows the gross fare, but part of it disappears into fuel and car wear (oil, tires, service). What's left is your margin — the money that actually reaches your pocket.

The math is simple: first the cost per kilometer = (fuel price ÷ kilometers per liter) + maintenance cost per km. Then the net profit = fare received − (km driven × cost per km).

Why it matters

Accepting a ride looking only at the gross fare is like billing without knowing your cost. A long, well-paying ride can earn less than a short one, depending on the route. Running this in seconds helps you turn down rides that don't cover the bills.

This math, automatic, on top of Uber

The JOBU app is a floating bubble that sits on top of Uber, 99 or Waze. You tap, type the distance and the fare, and see the net profit instantly — without leaving the map or opening a browser. Want to be notified at launch?
