The cost of getting from San Francisco International Airport to the city depends on your transport choice, the time of day, and your exact destination. Here is what you can realistically expect in 2026.
BART — The budget-friendly default
BART from SFO to downtown stations like Powell Street or Montgomery costs $11.15 per person one-way, or $22.30 round trip (bart.gov fare calculator, 2026). Children under 5 ride free. You buy a Clipper card at the station or tap a contactless payment card. The ride takes about 30 minutes. This is the cheapest fixed-price option for solo travelers or couples heading to areas near BART stations.

Other destinations
Taxis — Metered and traffic-dependent
Taxis at SFO run on the SFMTA metered tariff: $4.15 for the first 1/5 mile, $0.65 for each additional 1/5 mile, $0.65 per minute of waiting/slow-traffic time, plus a $6.00 SFO pickup fee (sfmta.com, current tariff). For the roughly 13-mile ride to Union Square or the Financial District, that works out to about $50-70 before tip, more if traffic is heavy. There is no official flat rate for this route — the meter runs door to door. For two or more people splitting the fare, a taxi can be competitive with BART once you factor in convenience.
Rideshare — Convenient but variable
Uber and Lyft from SFO to downtown use dynamic, demand-based pricing shown in the app before you confirm. Fares rise during peak hours, events, or holidays. There is no fixed rate to quote — check the app for a live estimate, and if it looks unusually high, waiting 15-20 minutes sometimes helps.
Private transfer — Fixed price, no variables
Pre-booked private transfers to downtown San Francisco offer a flat rate agreed at booking, which includes waiting time, flight tracking, and meet-and-greet. There is no meter, no surge, and no tipping uncertainty — check the live quote for your route, dates, and vehicle size (larger vehicles for families or groups cost more than a standard sedan).
Destinations beyond downtown
Pricing increases for destinations outside central San Francisco — Oakland, Palo Alto/Mountain View, Napa Valley, and Berkeley are all further and typically cost meaningfully more than the downtown fare. Rideshare and private-transfer pricing to these areas is dynamic and distance-based, so get a live quote for your specific trip rather than relying on a fixed estimate.
The bottom line
For a single traveler heading downtown during the day, BART at $11.15 is hard to beat. For two or more people, a taxi or rideshare splits well. If you want a guaranteed price and someone waiting for you — especially late at night or with heavy luggage — a pre-booked transfer removes the guesswork; check the live quote before you travel. The worst deal is usually a surge-priced rideshare during Friday evening rush hour.
When a private transfer from SFO is the right choice
- Three or more people: a 4-seat car to Napa Valley is from €174, about €44 per person, usually level with or below separate public-transport tickets once you count the walk, the wait and the last mile with bags.
- Going to a specific address rather than the main station: the car goes to the door, so the public-transport fare is not the whole cost of the trip.
- Arriving tired or late: the driver waits at arrivals with your name, included for 60 minutes after landing.
