How this is calculated

Lifestyle inflation measures how much of each raise spending absorbs instead of savings.

What drives the result

Income minus expenses equals surplus. Annualize habits to see their scale, track variance to catch drift, and automate the savings share before lifestyle absorbs it. Net worth is the scoreboard; the savings rate predicts how fast it grows.

Recommendations

  • •Cap lifestyle at 50% of every raise.
  • •Upgrade one category at a time.
