The Post Office RD Calculator estimates your maturity amount by:

• Calculating compound interest on your monthly deposits
• Considering the current Post Office RD interest rate
• Computing the total interest earned over the investment period
• Providing a detailed breakdown of your investment returns

Detailed Explanation:

This calculator uses the compound interest formula to determine your Post Office RD maturity amount:

Maturity Amount Calculation:

• Maturity Amount = P × (1 + r)^n
• Where:
• P = Monthly Deposit Amount
• r = Monthly Interest Rate (Annual Rate ÷ 12)
• n = Total Number of Months

Example Calculation:

• If Monthly Deposit = ₹5,000
• Annual Interest Rate = 5.8%
• Monthly Interest Rate = 5.8% ÷ 12 = 0.483% = 0.00483
• Investment Period = 5 years = 60 months
• Then: Maturity Amount = 5,000 × (1 + 0.00483)^60 = ₹3,47,850

Total Interest Calculation:

• Total Interest = Maturity Amount - (Monthly Deposit × Total Months)
• In the example above: Total Interest = ₹3,47,850 - (₹5,000 × 60) = ₹47,850

Important Notes:

• Post Office RD interest rates are subject to change
• This calculator uses the current interest rate for estimation
• Actual returns may vary based on rate changes during your investment period
• Premature withdrawal rules and penalties apply as per Post Office guidelines

This calculator also includes text-to-speech functionality to announce your calculated maturity amount, making it more accessible for all users.
