Understanding Compound Interest
Compound interest is the interest you earn on both your original money and the interest you've already earned. The formula is: A = P(1 + r/n)nt where A is the final amount, P is principal, r is annual rate, n is compounding frequency, and t is time in years.
🚀 Start Early
Time is your greatest ally. The sooner you start, the more compound interest works for you.
📈 Be Consistent
Regular contributions, even small ones, can lead to significant wealth over time through compounding.
🎯 Frequency Matters
More frequent compounding (monthly vs annually) can significantly boost your returns.
