Hi Product Hunt! 👋 I’m Sepehr, the maker behind RegretCalculator.net. The idea for this came from a simple personal habit: looking at my daily discretionary spending (like expensive coffee or takeout) and wondering what that money would actually look like over the long haul if it had been put to work in the markets instead. I built it as a side project, but it quickly took off. We’ve already helped over 10,000 users across 42 countries visualize their financial opportunity costs! I wanted to keep that momentum going by creating a completely private utility. By inputting any habit, expense, or dollar amount, you can instantly see how past investment decisions or missed asset opportunities (across major stocks, ETFs, and crypto) scale up over time. It’s an eye-opening way to visualize financial FOMO and re-frame how we look at daily expenses. The tool is completely free and requires zero login or personal data to use. We have a lot of exciting features planned to help users analyze historical market data and map out future habits. You can check out our pipeline and see upcoming updates directly on our live Product Roadmap: https://regretcalculator.net/roa... I'd love to hear your thoughts, feedback, or any feature requests you have. What habits are you tracking? Let me know in the comments below!👇
