## Frequently asked questions

- **How long will $40,000 last in Tokyo?**: For a founder burning $4,000/month with about half of that fixed (subscriptions, debt, insurance), $40,000 lasts roughly 11.1 months in Tokyo — versus 10 months staying in the US. That's 1.1 extra months, a ×1.11 runway multiplier.
- **Is Tokyo cheaper than the US for a remote founder?**: Tokyo's cost level runs about 80% 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 ×1.11 rather than the raw price ratio.
- **How do I calculate my own runway?**: Use the interactive Runway Multiplier: enter your real savings, monthly burn and the fixed portion, in any currency, and compare up to three hubs at once with exact run-out dates.
