Show HN: Free salary converter with 3,400 neighborhood comparisons in 182 cities

Hi HN, I built this because when I was considering relocating, I couldn't find a salary comparison tool that went deeper than city-level averages. A $100K salary in "New York" means very different things depending on whether you live in Manhattan or Queens.

What it does: enter your current city, a target city, and your salary. It calculates an equivalent salary adjusted for cost of living, local taxes, rent, and currency exchange — down to the neighborhood level.

Some things that make it different:

3,400+ neighborhoods across 182 cities, not just city averages Single and family mode (adds childcare, larger apartments) Side-by-side tax breakdowns by country 67 currencies with real-time conversion Also has a Retire Abroad calculator for retirement planning The data comes from a combination of public sources (OECD, local government stats, housing indices) cross-referenced and normalized to a cost-of-living index where New York = 100.

No signup, no paywall, no ads. Would love feedback on the methodology or data accuracy — especially from people who've actually relocated between cities we cover.
