Rental Car Cost Calculator
Total rental car cost from daily rate, number of days, insurance, and fees.
About the Rental Car Cost Calculator
The Rental Car Cost Calculator gives you an instant answer from just a few inputs — daily rental rate, rental days, insurance per day, and more. It runs entirely in your browser, so the numbers you enter stay private and never touch a server, and the result recalculates the moment you change a value. It's free to use with no sign-up, no limits, and nothing to install.
Worth Knowing
The advertised daily rate is reliably the smallest part of the bill. Airport locations add concession recovery fees and facility charges that commonly add 10% to 30%, which is why renting from a neighbourhood branch a short ride away is often dramatically cheaper on a week-long rental. Add state and local taxes, a vehicle licensing fee, and any one-way drop charge, and the effective daily cost can run half again above the quoted rate. The insurance decision is where the most money is wasted. The counter will offer a collision damage waiver — not technically insurance but a waiver of their right to charge you for damage — typically at $15 to $30 a day. Before accepting, check two things you may already have: your personal auto policy, whose collision and liability coverage usually extends to rentals within the US, and your credit card, since many cards provide rental car coverage automatically when you pay with them, though most are secondary to your own policy and a smaller number offer primary coverage that avoids a claim on your personal insurance entirely. Decline the prepaid fuel option unless you are certain you will return the car nearly empty, since you are buying a full tank and gifting back whatever is left. Watch the young-driver surcharge under 25, additional-driver fees, and the toll transponder, which often carries a daily convenience charge whether or not you pass a toll.
