Compound Interest Calculator
Analyze the exponential power of compounding interest across daily, monthly, quarterly, and annual intervals.
About the Compound Interest Calculator
The CalcNest Compound Interest Calculator demonstrates the exponential power of compounding interest across daily, monthly, quarterly, and annual intervals. Calculate maturity values and see how frequently compounding reinvestment accelerates financial growth.
Mathematical Formula
A = P × (1 + r/n)^(n × t) | CI = A - P Compound interest adds accumulated interest back to the principal, enabling exponential growth where interest earns further interest in subsequent periods.
Variables & Components
Worked Example: ₹1,00,000 Compounded Annually at 8% for 5 Years
Investing ₹1,00,000 for 5 years at an 8% annual compound interest rate.
Step-by-Step Calculation
- Annual rate: r = 0.08, n = 1 compounding per year
- Growth factor: (1 + 0.08)^5 = (1.08)^5 = 1.46933
- Final Amount: A = 1,00,000 × 1.46933 = ₹1,46,933
- Total Compound Interest: ₹1,46,933 - ₹1,00,000 = ₹46,933
- Compare with Simple Interest: Simple interest would only yield ₹40,000 (Compounding adds ₹6,933 extra)
