Frequently asked questions
- How long will $40,000 last in San Francisco?
- For a founder burning $4,000/month with about half of that fixed (subscriptions, debt, insurance), $40,000 lasts roughly 9.3 months in San Francisco — versus 10 months staying in the US. That's 0.7 fewer months, a ×0.93 runway multiplier.
- Is San Francisco cheaper than the US for a remote founder?
- San Francisco's cost level runs about 116% of the US in this model, so the local slice of your burn shrinks accordingly. Fixed costs don't move, which is why the multiplier is ×0.93 rather than the raw price ratio.
