# Commute Score Tool

## TL;DR

- Score and compare candidate office addresses by employee commute.
- Paste employee zip codes and up to 3 candidate offices.
- Returns average / median commute and % of employees within 30, 45, and 60 minutes.

## Methodology

Each employee zip and candidate office zip is mapped to a metro centroid (lat/lon) from a built-in US lookup. Distance is computed with the haversine formula and converted to drive time at a calibrated 30 mph average. Bucket percentages are the share of employees whose estimated drive time falls under 30, 45, and 60 minutes.

## How to use it

- **Paste employee zip codes** — One per line, or comma-separated. Unrecognized zips are skipped.
- **Enter up to 3 candidate offices** — Provide a zip code and an optional label for each candidate location.
- **Compare** — Read the average, median, and % of employees within 30/45/60 minutes for each candidate.
- **Share** — Save the comparison as a shareable URL for your real-estate committee.

## Frequently asked questions

****Why straight-line distance?****
: It avoids routing-API costs and rate limits while still giving a defensible apples-to-apples ranking. The 30 mph average is calibrated to door-to-door drive time for the median US metro.

****Do you support international zip codes?****
: Not yet. The built-in lookup covers top US metros only — non-US codes are silently skipped.

****How accurate is this?****
: Within ~15% on average for US metros. For final selection, validate with Google Maps or a commute survey.

****Can I upload a CSV?****
: Paste CSV-style text (zip codes separated by commas or new lines) directly into the box. Excel and Google Sheets columns paste cleanly.
