The cheapest Boston car rentals come from airport off-site lots, not the airport itself
Boston Logan Airport charges a facility fee on top of the rental rate — usually $5 to $8 per day — that you avoid by renting from a location a few miles away. Enterprise, Budget, and Hertz all operate off-airport branches in nearby neighborhoods like Revere and Malden. You'll save $15 to $40 on a three-day rental just by taking a rideshare to the lot instead of walking out of the terminal.
The actual cheapest rates come from comparing the same car type across all companies on the same dates. A compact car from Enterprise might be $35 per day while Hertz charges $42 for the same vehicle. That $7 difference compounds to $21 over three days. Use Google Flights, Kayak, or Autoslash to search all companies at once — don't check each website separately.
Timing matters more than location. Renting on a weekday costs less than a weekend rental for the same car. A Monday pickup in Boston might be $28 per day; the same car on Friday could be $45. If your trip is flexible, shifting by two days can cut your total cost by 30 percent.
Key Takeaways
- Off-airport rental locations in Revere, Malden, and Watertown avoid the $5 to $8 daily facility fee charged at Logan Airport.
- Comparing rates across Enterprise, Budget, Hertz, and Avis on the same dates usually reveals $5 to $15 daily differences for the same car type.
- Weekday rentals cost significantly less than weekend rentals, sometimes 30 to 40 percent cheaper for the same vehicle.
- Your credit card may cover collision damage waiver, so declining the rental company's insurance can save $12 to $25 per day.
What the advertised price actually includes
The rate you see quoted — say, $32 per day — does not include taxes, airport fees, or insurance. In Massachusetts, rental car tax is 6.25 percent. If you're renting at Logan, add the facility fee. If you decline the company's collision damage waiver and your credit card covers it, you save money; if you don't have that coverage, you're paying out of pocket for any damage. A $32 daily rate becomes $38 to $42 per day once taxes and fees are added.
One-way rentals cost more than round-trip. Returning the car to a different location than where you picked it up triggers a drop-off fee, usually $50 to $150 depending on distance. If you're flying into Boston and driving to New York, expect to pay that fee on top of the daily rate.
Fuel charges vary by company. Some let you return the car empty and charge you per gallon (usually $6 to $8 per gallon, well above market rate). Others require you to return it full or charge a flat refueling fee. Returning the car with a full tank yourself is almost always cheaper than either option.
Off-airport locations that undercut Logan prices
Enterprise has branches in Revere (Route 1), Malden, and Watertown. Budget operates in Revere and Malden. Hertz is in Revere and Watertown. All three are 10 to 15 minutes from the airport by rideshare, costing $15 to $20 depending on traffic. On a three-day rental, that rideshare cost is offset by avoiding the facility fee alone.
Downtown Boston locations (near the Prudential Center or Downtown Crossing) are more expensive than airport locations because they charge premium rates for urban foot traffic. Avoid them unless you're renting after you've already arrived in the city and don't want to travel to an off-site lot.
Check the specific address before booking. Some "Boston" listings are actually in suburbs 20 miles away. Verify the location on Google Maps and confirm the rideshare cost from Logan before committing to a reservation.
Insurance decisions that actually save money
Rental companies offer collision damage waiver (CDW) or loss damage waiver (LDW) for $12 to $25 per day. Before you buy it, check whether your personal auto insurance or credit card covers rental cars. Most major credit cards (American Express, Visa Signature, Mastercard Black) cover collision and theft if you charge the rental to that card. Your own auto insurance may also cover rentals, especially if you have comprehensive and collision coverage.
Call your insurance company or credit card issuer before you rent. Ask specifically whether they cover rental cars, what the deductible is, and whether they cover damage from theft or vandalism. If you have that coverage, declining the rental company's insurance saves you $36 to $75 on a three-day rental.
If you don't have coverage through your card or insurance, buy the rental company's waiver. The risk of paying $2,000 to $5,000 out of pocket for accident damage is not worth saving $50 on the rental.
Membership programs and discount codes that work
AAA members get 10 to 20 percent off at most major rental companies. If you're a AAA member, always search through the AAA website or call the company's AAA line rather than booking directly. The discount applies to the base rate, not taxes and fees, but it still saves $8 to $15 per day on a typical Boston rental.
Costco Travel offers discounted rental rates through partnerships with Enterprise and other companies. You don't need a Costco membership to use Costco Travel; you can purchase a membership for $60 per year just for the travel discounts. On a week-long rental, the savings often exceed the membership cost.
Corporate discount codes are real but usually modest — 5 to 10 percent off. If your employer has a code, use it, but don't expect it to beat AAA or Costco. Promotional codes (often found in email or on the company's homepage) vary by week and are worth checking, but they rarely exceed 15 percent off.
Comparing Boston rental companies side by side
| Company | Off-Airport Locations | Typical Daily Rate (Compact) | Facility Fee at Logan | CDW Cost Per Day |
|---|---|---|---|---|
| Enterprise | Revere, Malden, Watertown | $28–$38 | $6 | $12–$15 |
| Budget | Revere, Malden | $25–$35 | $7 | $14–$18 |
| Hertz | Revere, Watertown | $30–$40 | $8 | $15–$20 |
| Avis | Revere | $32–$42 | $7 | $16–$22 |
Rates vary by date and availability, so these are ranges based on typical weekday rentals in off-season months. Weekends and summer months are 20 to 40 percent higher. The cheapest option on your specific dates may not be the cheapest company overall.
Fuel and return logistics that cost extra
Most Boston rentals charge $0.25 to $0.35 per mile for one-way returns. If you're returning the car 50 miles away, that's $12.50 to $17.50 on top of the daily rate. Round-trip rentals (picking up and returning to the same location) have no mileage charge.
Fill the tank yourself before returning the car. Gas stations near rental lots charge market rates ($3.50 to $4.00 per gallon in Massachusetts). Rental companies charge $6 to $8 per gallon if you return the car empty. On a 15-gallon fill-up, that's a $30 to $60 difference.
Return the car during business hours. Late returns (after 5 or 6 p.m.) sometimes trigger an extra day's charge, even if you're only an hour late. Check the rental agreement for the exact cutoff time.
Frequently Asked Questions
Is it cheaper to rent from a car-sharing service like Zipcar instead of a rental company?
Car-sharing works if you need the car for a few hours or a day in the city. Zipcar charges hourly ($10 to $15) plus a membership fee. For a three-day trip or longer, traditional rental companies are cheaper. Zipcar also doesn't cover long-distance driving well — rates spike for trips over 180 miles per day.
What happens if I return the car with damage I didn't cause?
Report any existing damage before you leave the lot. The rental company will photograph it and note it on your agreement. If you don't report it and return the car with that damage, you may be charged for it. Always do a walk-around inspection with the agent before driving away.
Can I negotiate the rental rate at the counter?
Rates are usually fixed, but if you find a lower rate online from a competitor, some companies will match it. Call the location directly and ask. Don't expect a discount just for asking — the company needs to see a competing quote.
Do I need to buy a GPS or can I use my phone?
Use your phone with Google Maps or Apple Maps. Rental company GPS units cost $10 to $15 per day and are outdated compared to your phone. Make sure you have a car phone mount and a charging cable before you leave the lot.
What's the difference between renting at Logan versus downtown Boston?
Logan airport locations charge a facility fee ($5 to $8 per day) that downtown locations don't. Downtown rates are higher overall because of urban location premiums. Off-airport locations in suburbs like Revere are usually cheapest because they avoid both fees and urban pricing.
