📈 Compound Interest Calculator — See How Your Money Grows
Welcome to the Free Compound Interest Calculator on calculator.cl! Compound interest is one of the most powerful concepts in finance — it helps your savings or investments grow faster over time because you earn interest not just on your original amount, but on accumulated interest as well.
This tool shows you how your money can grow over a specified period with compound interest, including optional regular contributions. No login required — enter your numbers and get results instantly.
🧠 What Is Compound Interest?
Compound interest means you earn interest on both:
your initial investment (principal), and
the interest that accumulates over time
This creates exponential growth, making compound interest especially powerful over long time horizons.
For example, if you invest $1,000 at an annual rate of 5%, after one year you’d have $1,050 — and the next year, you earn interest on $1,050.
🧮 How It Works
To calculate compound interest:
Enter the initial investment amount (principal)
Enter the annual interest rate (%)
Enter the compounding frequency (e.g., yearly, monthly, daily)
Enter the number of years you plan to invest
(Optional) Enter regular contributions (monthly or yearly)
Click Calculate
The calculator uses standard compound interest formulas to estimate:
Final value of your investment
Total interest earned
Growth over time (if contributions are included)
Results give you a clear picture of how your savings grow with compounding.
📊 Compound Interest Formula
When contributions are not included, the formula for compound interest is:
A=P×(1+rn)ntA = P × \left(1 + \frac{r}{n}\right)^{nt}A=P×(1+nr)nt
Where:
A = final amount
P = principal (initial investment)
r = annual interest rate (decimal form)
n = number of times interest is compounded per year
t = number of years
With contributions, the calculator adds regular deposits into the growth formula automatically.
📍 Example Calculation
Suppose:
Principal = $5,000
Annual interest rate = 5%
Compounded monthly (12 times/year)
Time = 10 years
Monthly contributions = $100
The calculator will show:
Your ending balance after 10 years
Total interest earned
Growth trajectory over time
This helps you understand the impact of contributions and compounding on your long-term savings.
🧠 Why This Is Useful
Use this calculator to:
Plan for retirement savings
Compare investment strategies
Forecast education or large purchase funds
Understand the power of compound growth
Evaluate the benefit of regular contributions
It’s a powerful financial planning tool for both short- and long-term goals.
💡 Tips for Best Results
Use annual rates in decimal form (e.g., 5% → 0.05) for manual checks.
Higher compounding frequency (e.g., monthly or daily) increases total returns.
Start early — compound interest works best over long periods.
⚠️ Important Notes
This tool estimates growth — real investment returns may vary due to fees, taxes, or market changes.
Always verify interest and compounding terms with your financial institution.
