User-Friendly Interface

You can stress test your retirement plan with a user-friendly interface via an interactive Pluto notebook. Currently, two notebooks are available:

  1. Retirement planning: a robustness analysis of a typical retirement plan consisting of a work and investment phase followed by a retirement and withdraw phase.
  2. coast FIRE planning: robustness analysis that includes a transitionary phase between work and retirement in which a person takes a low-stress job

while investments grow.

As shown in this static preview, you can configure the stress test by entering your information into the fields without the need to write code. However, if desired, you can reveal the content of the cells and edit the code for further customization.
