Rental car adjusted direct operating expense per day measures adjusted direct operating cost for each revenue-generating transaction day.

Hertz reported Americas RAC adjusted DOE per Transaction Day of $38.13 in Q2 2026 versus $36.45 a year earlier. Total-company adjusted DOE per day was $37.49.

DOE per day separates operating friction from fleet ownership cost

Hertz begins with direct operating expense, removes foreign-currency effects and specified miscellaneous or non-recurring items, then divides by rental days.

The result helps isolate operating cost efficiency as volume changes.

It does not include the full cost of owning and financing the fleet. Fleet cost per unit per month and vehicle interest cost answer separate questions.

Cost per day should be read against RPD, not alone

Hertz also discusses the spread between revenue per day and DOE per day.

If RPD rises faster than operating cost per day, the direct rental economics can improve even if DOE itself increases. That spread is analytical, not a substitute for segment EBITDA because depreciation, interest, SG&A, and other costs remain outside it.

Part of the Rental Car Operating Economics

Connect rental-day demand, rentable fleet capacity, utilization, daily and per-vehicle revenue productivity, fleet carrying cost, direct operating cost, program-vehicle residual-value exposure, and vehicle financing cost.

Where this concept fits
  • Fleet carrying, operating, residual-value, and financing costCurrent relationship
    Per-unit fleet cost captures depreciation and related vehicle-value economics under issuer-specific definitions, adjusted direct operating expense per day captures day-to-day rental operations, program-vehicle mix changes residual-value exposure, and vehicle interest adds the financing layer. These measures are complementary rather than a standardized industry cost stack.

  • Rental volume, fleet capacity, and utilization
    Rental or transaction days measure consumed rental volume, average rental fleet measures the vehicle base, available rental days convert that fleet into time-expanded capacity, and utilization connects consumed days with available capacity. Avis and Hertz denominator conventions remain issuer-specific.

  • Daily pricing and fleet revenue productivity
    Revenue per day measures monetization on rented days, while revenue per unit per month spreads revenue across the rentable fleet. The second measure therefore combines rate, volume, and utilization rather than acting as another daily-price metric.
