Generally, a 7-day rental can be cheaper on a per-day basis thanks to weekly pricing, but your total cost depends on the exact dates, pickup location, and terms. If you only need 5 days, you should compare the complete price for 5 days at the daily rate with the total price of a 7-day booking (including any penalties for shortening or changes) to determine which option saves you money.
How rental pricing is typically structured
Most car rental companies present two common pricing frames: a daily rate and a weekly (7-day) rate. The weekly rate is often cheaper per day, but the terms—such as minimum rental periods, how shortening a booking is handled, and what charges apply—vary by provider and location.
- Daily rate vs weekly rate: daily pricing is charged per calendar day, while a weekly rate covers a 7-day block with a lower per-day cost.
- Minimum rental periods: some agencies require a minimum rental, which can influence whether a 5-day window qualifies for a weekly rate.
Understanding these elements helps you compare the true total cost for 5 days versus a 7-day booking.
How to compare for your dates
To determine which option saves money for your specific trip, follow these steps and keep the dates and locations consistent across quotes.
- Get quotes for a 5-day rental using the standard daily rate with identical pickup/drop-off times and location.
- Get quotes for a 7-day rental using the weekly rate, using the same pickup/drop-off details; verify whether shortening is allowed without penalties.
- Compare the all-in total price (base price + taxes/fees + insurance/optional extras + fuel and mileage charges).
- Check for any hidden costs such as airport surcharges, one-way fees, or different rates by pickup location.
- See if adjusting dates or picking a different location could unlock a lower price or better promo.
By comparing the all-in prices for both options with your exact dates, you’ll know which choice is cheaper for your trip.
Common pitfalls and practical tips
A few practical considerations can affect whether 5 days or 7 days is cheaper in practice.
- Airport vs non-airport locations: airport pickups often carry additional fees that can affect the total price.
- Penalties for early return: some agencies charge for unused days if you shorten a weekly booking.
- Promotions and memberships: loyalty programs, corporate rates, or aggregators can change which option is cheapest.
- Extra add-ons: GPS, child seats, or extra drivers can swing the total cost; sometimes you can use your own devices and avoid charges.
Carefully reviewing these aspects helps prevent surprises and ensures you select the most economical option for your dates.
Summary
The typical takeaway is that a 7-day rental often offers a better per-day deal due to the weekly rate, which can make the total cost lower than paying 5 days at the regular daily rate. However, the actual cheapest option depends on your exact dates, location, and the rental terms (especially minimums, penalties for shortening, and added fees). Always calculate the all-in price for both scenarios with your pickup and drop-off details to decide which option is cheaper for your trip.
