About this tool

I built this because most compound interest calculators are ugly, US-centric, or buried in financial jargon. You shouldn't need a finance degree to understand how your money grows over time.

If you're an expat in Dubai, a fresh grad in Kuala Lumpur, or someone in Cairo who just opened their first brokerage account — this is for you. Pick your currency, set your numbers, and see what consistency looks like over 10, 20, or 30 years.

The math is straightforward. Monthly compounding, with an optional inflation adjustment so you can see what your future money is actually worth in today's terms. No hidden assumptions, no upsells, no “sign up for our premium plan.”

The default 10% return rate isn't a promise — it's roughly what the S&P 500 has returned historically over long periods. Your actual returns will vary. The point isn't precision. It's building intuition for what long-term investing looks like.

This tool is open source and free to use. If you found it useful, share it with someone who's just starting to think about investing.
