Compare the trip you are actually taking, with the same dates and conditions in both offers.
01 / DURATIONCount the return time, not just the nights.
A hotel stay measured in nights and a vehicle rental measured in billing periods are not automatically the same. Put the pickup and return times in both quote requests. Ask how late return, grace periods and extensions are handled. For a weekly or monthly offer, enter its quoted base total directly rather than assuming a day-rate multiplication. The calculator uses the amounts you enter; it does not invent a provider’s discount schedule.
02 / CASH FLOWA refundable hold is not a rental charge.
Keep the refundable amount separate when comparing offers. Ask whether it is a card authorization or a collected payment, when the release is initiated and which conditions can affect the return. The calculator shows rental cost and an initial funds estimate separately. Actual payment timing can differ if part of the rental is paid later. Confirm the final invoice and deposit arrangement with the provider before reserving.
03 / COMPARISONMake both offers cover the same trip.
A lower total is meaningful only when the quotes cover the same dates, mileage, driver eligibility, protection and delivery arrangements. Put known mandatory charges into each offer. Do not enter zero because a fee is unclear—ask for the figure first. Keep optional extras separate until you decide whether you need them. If one offer excludes something essential, add its confirmed cost before judging the difference.
