Internet in San Francisco

In M-Lab's open speed tests within 25 km of San Francisco, half came in above 113 Mbps download and 27 Mbps upload, and the fastest quarter of lines above 321 Mbps.

That's 4,188,981 download tests from September 2025 to September 2026.

The typical figure counts every line, cheap and mobile ones too; a fiber line in a good apartment or coworking space is closer to the fastest quarter.

Cost of living in San Francisco

One person spends about $4,745 a month in San Francisco, with a furnished place to stay:

The rent is the lower quarter of Inside Airbnb's 763 studios and one-bedrooms that take stays of a month or more, from its June 2026 listings.

The rest is what a one-person US household spends (the Bureau of Labor Statistics' 2024 survey), at the US's prices for each (the World Bank's 2021 price comparison).

Coworking, insurance and flights come on top.

Here's what a furnished studio or one-bedroom lists for in the neighborhoods with the most month-long stays:

That's each listing's nightly price times 30, before any monthly discount a host gives, so a booked month often comes in lower.

Visas, taxes and residency in the US

Before you plan a long stay, check what your passport allows and what staying does to your taxes:

• Can you stay? – see where your passport goes without a visa on the visa-free countries map, and whether the US has a visa for remote workers in the digital nomad visa finder
• Tax – compare the US's income tax with other countries in tax rates by country
• Foreign income – the US taxes its citizens on their income wherever they live; see the rule and its exceptions on the territorial tax map

Each tool reads the official rules, so the answer is for your own passport and income.

Money in San Francisco

A card with no foreign fee and an account that holds several currencies make a stay much cheaper:

The finders show only accounts and cards you can open from where you live.
