Where to find rental cars under $50 a day in San Juan
The cheapest car rentals in San Juan come from local companies rather than the big international chains. Companies like Vroom, Thrifty, and Budget have desks at Luis Muñoz Marín International Airport, but local operators like Hertz Local, Avis Local, and independent shops in the Santurce neighbourhood often undercut them by $10 to $20 per day. The actual lowest price depends on your travel dates, how long you rent, and what type of car you need.
Airport rentals cost more than off-airport pickups because the airport charges concession fees that get passed to you. If you stay near Old San Juan or the Condado district, renting from a location in those neighbourhoods can save money and eliminate the need for a taxi to the airport rental desk. Many local companies will deliver a car to your hotel for a small fee, which can be cheaper than the airport premium.
Booking directly with the rental company's website often costs less than going through comparison sites, because those sites add their own markup. Call the company's San Juan location directly and ask about their current daily rate—you may find a better price than what appears online.
Key Takeaways
- Local rental companies in San Juan typically charge $15 to $30 less per day than international chains at the airport.
- Renting from an off-airport location in Old San Juan or Santurce saves the airport concession fee, which can be $5 to $10 per day.
- Booking directly with the rental company's phone number usually costs less than using comparison websites.
- Your driver's license, passport, and a valid credit card are the documents you need; some companies require an International Driving Permit if your license is not in English.
- Collision damage waiver (CDW) insurance is optional but strongly recommended because Puerto Rico roads are narrow and parking is tight.
What documents and insurance you actually need
You need a valid driver's license, your passport, and a credit card in your name. If your license is not in English or Spanish, some rental companies will ask for an International Driving Permit (IDP), which you can get from your home country's automobile association before you travel. Puerto Rico recognizes US, Canadian, and most European licenses without an IDP, but calling ahead to confirm saves frustration at the counter.
Collision damage waiver (CDW) insurance is not required by law, but it is worth the cost in San Juan. The roads in Old San Juan are one-way and narrow, parking spaces are tight, and minor dings happen frequently. Without CDW, you pay for any damage out of pocket—even small scratches can cost $300 to $500 to repair. Your personal car insurance or credit card may cover rental damage, so check your policy before you book. If you are covered at home, you can decline the rental company's CDW and save $12 to $18 per day.
Liability insurance is included in all Puerto Rico rentals by law. You do not need to purchase additional coverage for damage you cause to other vehicles or property.
How to avoid hidden fees at pickup
The quoted daily rate is rarely the final price. Rental companies add airport concession fees (5 to 10 percent), fuel charges, and local taxes (11.5 percent in Puerto Rico). Ask the rental company for the total cost including all fees before you confirm your booking—not just the daily rate.
Fuel charges are the biggest hidden cost. You can either prepay for a full tank at the rental rate (usually cheaper than filling up yourself) or return the car with a full tank and pay the rental company's pump price, which is marked up. Prepaying for fuel makes sense if you will use most of a tank; if you are renting for two days in the city, you may use only half a tank and overpay.
Some companies charge for additional drivers, GPS units, or child seats. If you need any of these, ask the price before you book. Declining the rental company's GPS and using your phone's maps app saves $5 to $8 per day.

Prices shown are estimates based on typical rates and vary by season, booking date, and car type. Rates are higher during winter months (December through March) and lower during summer. Local companies like Vroom and smaller independent operators in Santurce often beat these prices by $10 to $20 per day.
When to book and what season costs the most
Winter (December through March) is peak tourist season in Puerto Rico, and rental car prices rise 30 to 50 percent. If you can travel in May, June, September, or October, you will find the lowest rates. Booking two to three weeks in advance gives you better prices than booking a few days before arrival, because popular dates sell out and prices climb.
Weekday rentals are slightly cheaper than weekend rentals, though the difference is usually only $3 to $5 per day. If your trip is flexible, renting Monday through Thursday costs less than Friday through Sunday.
Last-minute bookings (within 48 hours of pickup) sometimes show lower prices online because rental companies discount unsold inventory, but this is not reliable. Booking in advance is the safer strategy for the best rate.
Driving conditions and insurance considerations in San Juan
San Juan traffic is heavy, especially in Old San Juan and along the coast. Drivers often ignore lane markings, and parking spaces are scarce and tight. Rental cars get dinged and scratched frequently, which is why CDW insurance makes financial sense even though it is optional. A single parking lot incident can cost $400 to $800 in repairs if you are uninsured.
Driving at night in some neighbourhoods carries higher risk. Stick to well-lit areas and main roads after dark. The airport is about 20 minutes from Old San Juan by car, and the drive is straightforward on PR-26 highway. Driving to beaches outside the city (Flamenco Beach on Culebra, for example) requires a ferry, so plan accordingly.
Tolls on Puerto Rico highways are paid with a CESCO card, which you can buy at gas stations or the rental company can add to your bill. Ask whether tolls are included in your rental agreement or if you will be charged separately.
Frequently Asked Questions
Can I rent a car with a US driver's license in Puerto Rico?
Yes. A valid US driver's license is accepted at all rental companies in San Juan without an International Driving Permit. You still need your passport as a second form of ID. If your license is expired or from a country that does not use the Latin alphabet, ask the rental company whether they require an IDP before you book.
What happens if I return the car late?
Late return fees vary by company but typically run $25 to $50 per hour or a fraction of the daily rate. Some companies charge a full day's rate if you return the car even 30 minutes late. Ask the rental company's late return policy when you pick up the car, and plan to return it with time to spare.
Do I need to buy the rental company's insurance if my credit card covers rental damage?
Check your credit card's rental car coverage before you decline the rental company's CDW. Many cards cover collision damage but exclude liability or have limits that do not cover Puerto Rico. If your card covers you fully, you can decline CDW and save $12 to $18 per day. If you are unsure, call your credit card company before you travel.
Is it cheaper to rent a car or use taxis and ride-sharing in San Juan?
For a one- or two-day trip staying in one neighbourhood, taxis and ride-sharing are cheaper. For three days or longer, or if you plan to visit beaches and towns outside the city, a rental car usually costs less and gives you more freedom. Calculate the cost of your planned trips before you book.
Can I rent a car one-way from San Juan to another Puerto Rico city?
Yes, most companies offer one-way rentals. One-way fees typically add $15 to $40 to your total cost, depending on the distance. Returning the car to the same location where you picked it up is always cheaper than a one-way rental.
