❓ Frequently Asked Questions (FAQs)
Q1: What is the formula for compound interest?
👉 The formula is:
A = P (1 + r/n)^{n * t}
Where:
A = Final Amount
P = Principal (initial balance)
r = Annual interest rate (decimal)
n = Number of times interest is compounded per year
t = Time (years)
Q2: Why is compound interest better than simple interest?
👉 Because in compound interest, you earn “interest on interest,” while simple interest only earns on the principal amount.
Q3: Who should use this calculator?
👉 Students, investors, business owners, financial planners, and anyone who wants to understand how their savings can grow.
Q4: Can this calculator be used for daily compounding?
👉 Yes! You can choose from daily, monthly, quarterly, semi-annual, or annual compounding options.
Q5: Does compound interest really make a difference?
👉 Absolutely. Over long periods, even a small difference in interest rate or compounding frequency can create a huge difference in returns.
