Most investment calculators show numbers that look good, but ignore real-world assumptions. Calc Rich helps you answer a better question: “Is this decision actually reasonable?” - Compound interest - Goal-based investing - Conservative vs optimistic scenarios Built for people who want clarity, not hype.

Hey Product Hunt 👋 I built Calc Rich after realizing how many investment calculators quietly assume perfect conditions. Most tools answer the question: “How much could I make if everything goes right?” But when I’m making real decisions, the question I care about is: “Does this actually make sense?” Calc Rich is a small but opinionated calculator that helps you: - Question optimistic assumptions - Compare conservative vs optimistic scenarios - Think in terms of decisions, not just returns This started as something I built for myself, and I’m sharing it to see if others find it useful too. I’d really love your feedback — what feels unclear, unnecessary, or missing?

Just to add a bit more context for anyone curious 👋

Calc Rich is a web app that works on both desktop and mobile,
and it’s currently 100% free.

All calculations and records are stored entirely on the client side.
There’s no account system and no data sent to a server —
I wanted to keep things simple and privacy-first.

You can save your calculations, reload them later,
and share your analysis with others.

Longer term, I’m exploring:

  • Optional backend support for better reliability

  • Integrations with crypto exchange APIs to import real trading data

Still very early, so honest feedback (good or bad) is more than welcome.
