Apps — Die With Zero · Bill Perkins Skip to main content

Companion tools

The book shows you why.
The apps show you how.

Die With Zero originally started as an app — until a longevity-focused doctor convinced Bill to write the book first. We built the apps anyway, so you can put the ideas to work on your own life.

Spend Curve App

Visualize different scenarios for maximizing the money you spend while you're still healthy enough to enjoy it. For a given set of inputs, the app shows the saving and spending pattern required to maximize fulfillment across your remaining years.

  1. Input your current age, retirement age, life expectancy, and net worth.
  2. Set your expected ROI and post-retirement benefits.
  3. Choose whether to frontload or backload activity preferences across the curve.

Time Buckets Toolkit

Time buckets help you design your life around experiences mapped to different windows of time. Enter the experiences you want to have during your lifetime — the app organizes them into 5-to-10-year buckets so you can actually make them happen.
