What the check shows

The number, what it means, and your next move.

How far you are from the median, your monthly take-home, whether your overtime is right — and, if you're below, what you can do.

What you get

One screen, every number sourced. Zero marketing spin — just the facts, so the judgment stays yours.

  • The median for your industry / age / region, and where you land
  • Your take-home pay, with the tax & insurance breakdown
  • Overtime, paid leave, and health-risk flags
  • Next moves: skills, a negotiation script, job listings
