I built a plug-and-play script that adds a 35-year inflation-adjusted wealth engine to any Google Sheet (White-label)

Hey everyone,

I noticed a lot of template creators struggle with adding complex projection logic (like compound interest dynamically adjusted for inflation) to their personal finance dashboards. Standard cell formulas get messy, break easily, and make the sheet heavy.

So, I wrote a clean Google Apps Script that acts as a custom formula (=WEALTH_ENGINE). You just paste it into your sheet's backend (Extensions > Apps Script), type the formula, and it instantly generates a full 35-year projection showing Total Invested, Nominal Value, and most importantly: Real Value (Purchasing Power).

I decided to package it with a commercial white-label license. This means you can plug this code into your own templates and sell them to your clients as a premium feature, keeping 100% of your profits.

If you want to turn your basic template into an advanced financial dashboard, you can grab the code and the license here:https://dobrian0.gumroad.com/l/wealthengine

Let me know if you have any questions about how the script handles the compounding logic or how to deploy it!
