For e-bike workers, batteries are the largest expense (32% of total expenses), followed by phone costs
(including both the device and data plan) (23%). For car drivers, the largest expense is depreciation (31%),
followed by traffic or parking tickets (28%).
The Department estimated the expenses of e-bike workers as follows. For depreciation, the Department
obtained the purchase price of a new e-bike through visits to NYC retailers ($1,800), applied five-year straight-
line depreciation consistent with IRS principles, and then reduced this amount to reflect the probability of loss
due to casualty or theft (5.88% annually),
66
which the Department estimated from its NYC Delivery Worker
Survey. For casualty and theft loss, the Department multiplied the probability of a loss incident by the expected
depreciated value of the e-bike at the time of incident ($959.13), assuming constant probabilities of loss during
the e-bike’s useful life. For batteries, the Department obtained the purchase price of a new battery by visiting
NYC retailers ($550) and multiplied the cost by workers’ average replacement rate (1.74 per year), which the
Department measured from its NYC Delivery Worker Survey. For maintenance costs, the Department used the
estimate of e-bike maintenance costs per mile provided by Uber Eats and DoorDash ($0.067)
67
and the
average trip distance per hour worked (2.17 miles), which the Department estimated from the record-level data
obtained from apps. For accessories, the Department used its NYC Delivery Worker Survey to estimate the
annual probabilities of purchasing handlebar gloves (63%), bike racks (37%), baskets (38%), helmets (67%),
lights (58%), horns (32%), reflective vests (39%), locks (74%), alarms (32%), anti-theft cameras (13%), anti-
theft GPS systems (32%), and clothes, shoes or rain gear for work (84%), and quoted prices for each
accessory from NYC retailers and internet sellers. For phone purchases, the Department used its NYC Delivery
Worker Survey to identify the mix of phone models used by delivery workers and quotes from internet sellers to
estimate the average purchase price ($721) as well as the average discounts or proceeds on trade-ins and
resales ($597). The Department then obtained the net expense by multiplying these amounts by the
frequencies of purchase (1.74 per year) and trade-in or resale (0.45 per year), respectively, from its NYC
Delivery Worker Survey. For data plans, the Department used the average cost of a single-line, unlimited data
plan as quoted from major carriers ($63.33 per month).

For both phone purchases and data plans, the
Department reduced estimated expenses to reflect percent use in app delivery, assuming 145.17 hours of
personal phone use per month, which is the mean of four recent studies,
69
and 21.3 hours of app delivery use
per week, consistent with the average for e-bike workers. For tickets, the Department used the frequencies of
receiving a ticket and the costs per ticket reported in its NYC Delivery Worker Survey. The Department then
converted all expenses into hourly rates based on e-bike workers’ average of 21.3 hours per week, except for
maintenance, for which an hourly rate was derived as described above (i.e., from data reflecting cost per mile
and miles per hour of working time).
To estimate car drivers’ expenses, the Department took the same approach as with e-bike workers for phone
purchases, data plans, and tickets as described above and accounted for vehicle-related expenses as follows.
For depreciation, the Department used its NYC Delivery Worker Survey to identify the model and year of cars
used by delivery workers, together with a database on historical fair market values
70
to determine bases for
depreciation. With this information, the Department then calculated depreciation using the five-year straight-line

Casualty or theft losses can be claimed as business expenses under IRS guidelines. A casualty loss is a sudden, unexpected destruction of
property. See Topic No. 515 Casualty, Disaster, and Theft Losses, IRS, https://www.irs.gov/taxtopics/tc515
