What is compound interest?

Compound interest refers to earning interest on both a loan or investment principal amount, as well as previously accumulated interest.

For example, say you invest $1,000 at a 7% annual rate paid monthly. After one month you’ll earn $5 interest on your original $1,000 principal (7%/12 months = ~0.58% monthly rate).

Now in month two, you’ll earn interest not just on your $1,000, but also on the $5 earned earlier. Your principal in month two equals $1,005 thanks to compounding gains. This cycle repeats, continually building on itself.

Over long periods, even small returns compound into far larger amounts through the power of exponentially growing interest upon interest. Understanding this unique concept unlocks the life-changing power of compound growth.

Why use a compound interest calculator?

Mapping realistic projections of compound growth reveals just how lucrative long-term saving and investing can become. It highlights the immense financial power you can leverage simply by harnessing the magic of compound interest.

For example, saving just $100 monthly in an account earning 5% interest will grow your money over 40 years:

    • Year 1 Balance = $1,200
    • Year 10 Balance = $16,470
    • Year 20 Balance = $42,583
    • Year 30 Balance = $84,152
    • Final Year 40 Balance = $149,006!

That’s over $150,000 accumulated from small $100 monthly contributions. This highlights the incredible results possible when compound returns relentlessly build upon themselves.

Predicting this growth yourself requires sophisticated financial calculations and models. Or you can simply utilize a compound interest calculator tool to instantly run projections.

Maximizing your compound interest results

Now that you’ve seen firsthand how quickly compound growth multiplies returns over time, let’s explore some key tips to maximize results:

  • Start Early – Begin compounding as soon as possible. Extra years build exponentially more value thanks to added compound cycles. Start small if needed, time matters most.
  • Invest Regularly – Develop consistent investing habits on an automated schedule, like monthly or per paycheck. This builds larger bases earning higher returns faster through continual compounding.
  • Reinvest All Returns – Reinvest all interest, dividends and capital gains to keep expanding your principal base earning compound returns. Avoid withdrawing interest income during the compound growth phase.
  • Embrace Market Volatility – Don’t panic over periodic downturns, see them as discounted buying opportunities to increase positions before the next growth cycle.
  • Upgrade Contribution Rates – Boost total investments whenever possible, even small raises quickly compound into serious extra capital in later years.

The key is consistency over time. Compound interest rewards regular,hands-off investments automatically compounding for years or decades. Maximum rewards go to those starting early and patiently sticking to ever-growing contributions.

Which account types offer compounding interest?

You may be wondering which financial vehicles actually provide compound growth. While not an exhaustive list, common accounts offering continual compound interest include:

  • High Yield Savings – Top online accounts offer up to 2% APY interest compounding daily on cash balances from $1 up to at least $250,000. No risk, excellent liquidity.
  • Certificates of Deposit (CDs) – Usually 3-10 year terms paying fixed interest for locking up funds, rates range from 3-7% APY compounding depending on duration. No risk.
  • Money Market Funds – Professionally managed short-term bond funds paying ~1-2% dividend yields through continual compounding. Very low risk.
  • Mutual Funds – Broadly diversified funds owning hundreds of stocks or bonds providing compounded growth through high single digit average total returns. Modest risk over 5+ year timelines.
  • Stocks (Equities) – Direct ownership shares in publicly traded companies delivering average 10%+ annual returns long-term through rising valuations and dividends. Higher risk, higher reward over 10+ year durations.
