Albert Einstein said "Compound interest is the eighth wonder of the world. He who understands it earns it… he who doesn’t… pays it." Or maybe it was Lincoln who said that. Or maybe Warren Buffett. Elon Musk? Never mind. It doesn’t matter who said it (it was Einstein), it only matters that you use compound interest to your advantage. If you’ve ever wondered how Warren Buffett built his fortune, the answer is simple: time + compound interest = massive wealth. This app helps you apply the same principle to your own investments. Calculate and plan out your investment so that you may "Retire Early" and achieve "Financial Independence". It is never too late to start snowballing your money! With some types of investments you might find that your interest is compounded daily, meaning that you are earning interest on both the principal amount and previously accrued interest on a daily basis. This is often the case with some bitcoin and crypto currency trading platforms. When interest is compounded so frequently on a fixed basis, it can mean that the interest accrued increases quickly, as every day's interest figure is bigger than the previous day. Whether you are an investor, planning to invest like Warren Buffet (that's how he made all of his wealth, through compounding after years) or want to invest more intelligently in the stock market, cryptocurrencies (like Bitcoin, Ethereum, IOTA, XRP, Litecoin, EOS, Bitcoin Cash, Binance Coin, SOL, AVAX, BLOK, DOGE, ...) then this simple app is for you. Use this daily compound interest calculator to get an estimate of the daily interest you might earn on your investment over a fixed number of days. Daily compound interest is calculated using a simplified version of the compound interest formula. Your money, your future: Start investing smarter today. Whether you’re a beginner or an expert investor, this app will help you take control of your financial future and make informed investment decisions.

Verdict
The clearest difference is rating: Interest Calculator at 4.8 against Compound Gain's 4.4. Interest Calculator also leads on update cadence (every 2 weeks vs every 2 months) and ratings volume (117 vs 14). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Compound Gain sells 2 in-app purchases, starting at $1.39 per month and Interest Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Interest Calculator holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Interest Calculator has 117 ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 80% of Compound Gain's written reviews are positive against 78% of Interest Calculator's, so the app with the better star average is not the one people write more warmly about.
Compound Gain ships an update every 2 months, Interest Calculator every 2 weeks. Both last shipped on October 24, 2026.
