👋 Hi Product Hunt! I built this Compound Interest Calculator to make investment planning simple and accessible for everyone. Most calculators only provide basic results. I wanted to create a tool that goes further by supporting 60+ currencies, recurring contributions, milestone tracking, retirement planning, and interactive growth charts—all in a clean, mobile-friendly interface. It's completely free, requires no sign-up, and works instantly in your browser. I'd love your feedback: • What features would make it even more useful? • What financial calculator should I build next? Thanks for checking it out and supporting Global Tools Box! 🚀

Would be super useful if you could compare two different contribution strategies side by side, like lump sum vs monthly contributions, since right now you kind of have to do the math in your head to figure out which actually wins out over time.

 Thank you for the fantastic suggestion, Ercan! 😊 Side-by-side comparison for different investment strategies like lump sum vs. monthly contributions is a brilliant idea. It completely eliminates the need for mental math and makes planning so much easier. I've added this straight to my feature roadmap for the next updates!
If you like the calculator, please consider sharing it with your network or friends—it would really help us grow! 🚀

Love how clean this is, no sign-up is a big win. One thing I'd suggest: add an "inflation-adjusted" toggle so the future value reflects today's purchasing power. That would make the retirement planning section way more useful for long-term projections.

 Thank you, Azat! 😊 Glad you like the clean interface and the sign-up-free experience.

An "inflation-adjusted" toggle is an incredible suggestion! It’s absolutely essential for accurate long-term retirement planning so users can see the real purchasing power. I've noted this down for our upcoming updates. If you found the tool helpful, please consider sharing it with your network—it would really help us grow! 🚀

The interactive charts paired with the milestone tracker are a really thoughtful touch, makes projecting long-term growth feel less abstract and more motivating.

 Thanks for the wonderful feedback, Yalçın! 🙌 I really wanted to couple the interactive charts with milestone tracking to make long-term financial goals feel more tangible and motivating for users. If you like the calculator, please consider sharing it with your friends or network. Really appreciate your support! 🌟

Played around with this for a few minutes and the milestone tracker is genuinely useful for visualizing when you'll hit different savings goals. Nice that it handles recurring contributions without making me sign up first.
