Sliding Scale v2.0
A more accurate and user-friendly version of the sliding scale, now called the Economic Equilibrium Sliding Scale is available here. Based on data from the US Bureau of Labor Statistics stratified by exact ages, you can discover your net worth percentile and receive suggestions on conducting transactions fairly relative to both parties net worth. We hope you check it out and find it useful! If you have feedback, please feel free to reach out.
Sliding Scale v1.0
This sliding scale survey was inspired by the work done by HD at Ride Free Fearless Money. I considered using the narrative approach in the survey, but after realizing it would be difficult to translate the tier reliably into a scale factor for a price, I decided to go as directly as possible to a quantitative assessment. To do so I referenced the data on net worth and income compiled and presented by PK at DQYDJ to create some JS arrays. Thanks to the help of folks who maintain the SurveyJS library, an unparalleled open-source survey library written in Javascript, I was able to develop a survey with a lot of custom logic generated with the help of R, and some custom Javascript to handle the survey results message.
Here hopes that this tool proves useful to you in self-evaluating where you land on a sliding scale.
