Online ads are pretty good. Guaranteed $ 2,500 a month to drive at Lyft or $ 2,100 a month for Uber, close to $ 30,000 a year for a part-time job for many.

But here is the bad news. First of all, there are a lot of small characters to manage that make the offers not as big. Secondly, a new study released on Tuesday shows that drivers are actually far fewer than four years ago.

More and more people are driving on the roads leading Uber and Lyft, and "the rapid growth in the number of drivers has resulted in a steady decline in average monthly earnings," says J. P. Morgan Chase & Co. Institute.

The earnings of people working in the field of online transport fell by 53% between 2013 and 2017, said Chase, averaging $ 783 per month in 2017, against $ 1,469 in 2013.

This, of course, is far from $ 2,500 a month.

To reach $ 2,500, Lyft says drivers will earn at least $ 625 a week and if they do not, Lyft will make the difference.

The conditions are that you must start working at 5 am, accept 90% of the available trips, drive at least 30 hours a week, for at least 65 trips.

For Uber, the car transport company notes that the amount of $ 2,100 applies only to the first 200 trips and that future earnings "are not guaranteed". 200 trips must be made within 90 days. And the guarantee is for total earnings minus Uber fees.

Meanwhile, DoorDash, the food delivery service, says that drivers can earn $ 1,750, but it's been over two months and with the delivery of 60 meals. As stated by Rideshareapps.com, drivers are also responsible for gas expenses, maintenance and taxes.

Notes Rideshareapps.com: The DoorDash website says that drivers can earn up to $ 25 / hour, which could be a stretch for most markets .However, you're guaranteed a minimum of $ 10 / hour. "

The site is even more honest in describing what it's like to drive for Lyft: "Sometimes it's slow and you do almost nothing, but other times you can do hundreds per night. make a murder. "
