About This Tool
Most people vastly underestimate their cost-per-use on purchases. This tool makes it concrete and gives you a personal value threshold tied to your actual hourly rate — helping you avoid future regrets before opening your wallet.
To track how much you lose on unused groceries, try the Food Waste Cost Calculator. For a full picture of your effective income, use the Hourly Rate Lie Detector.

How It Works
The personal threshold is half your hourly rate — the intuition being that an item should cost no more per use than what you earn in 30 minutes. The warning score normalises cost-per-use onto a 0–100 regret scale, hitting 100 when cost-per-use is double your threshold.
