SFO parking vs Uber or Lyft: do the round-trip math.

Parking gets more expensive with every day. Rideshare changes with distance, demand, and timing. Enter the two fares shown in your app and find the exact trip length where the cheaper option flips.

Independent calculator: No parking or rideshare company paid to appear. The $27 SFO Long-Term default comes from SFO; the $45 rideshare fares are clearly labeled examples, not live quotes. Millbrae Local receives no booking commission.

Editable cost comparison

Use the prices on your screen.

Check both directions because airport pickup, traffic, and surge pricing can make the return ride different. Include any parking promotion and the real cost of driving to SFO.

Illustrative defaults: Replace both $45 rideshare examples with current app quotes. Quote totals usually include platform and airport fees but not an optional tip—confirm before entering a tip percentage.

Make it a fair comparison

Six inputs can change the winner.

Both ride directions

Use a separate quote for departure and return; demand can differ sharply.

Tip treatment

Do not add a tip twice. Enter zero if your quoted total already includes everything you plan to pay.

Parking clock

SFO Long-Term charges by elapsed parking periods. A partial extra period can affect the final bill.

Reservation savings

Subtract only a discount shown for your exact parking dates and product. Verify combined free-day and percentage offers with the parking discount calculator.

Driving costs

Add gas and tolls you avoid by leaving the car at home; do not invent a depreciation cost you would ignore in practice.

Convenience

Price cannot capture luggage, child seats, accessibility, pickup waits, or the value of having your own car on return.

Calculator help

Common questions.

How does the break-even day work?

It is the trip length where drive-and-park and round-trip rideshare cost the same. The calculator also shows the first whole parking day when rideshare becomes cheaper.

Does the rideshare quote include SFO fees?

Use the final fare estimate shown in your app for each direction. Check the quote details rather than adding an airport fee separately, then add only the tip you actually expect to pay.

Why is the parking default $27?

SFO currently lists a $27 maximum per 24 hours for Long-Term Parking, including taxes and fees. Replace it with the live prebooked rate or another lot's final daily cost.

Can I compare BART or an off-airport lot?

Yes. Use the Millbrae and SFO parking calculator first, then put the relevant parking total into this comparison by editing the daily rate, discount, and driving costs.

What if I also need a hotel?

Use the SFO Park and Fly calculator to compare a hotel package with a room plus separate parking and transportation.
