Growing Your Savings: Recurring Deposit (RD) Calculator

A Recurring Deposit (RD) is a special kind of term deposit offered by banks and post offices in many countries, which allows individuals to make regular monthly deposits of a fixed sum over a predetermined period and earn interest. Our RD Calculator helps you estimate the maturity value of your RD investment.

💸 How to Use the RD Calculator

To estimate your RD returns:

1. Enter Monthly Deposit Amount: Input the fixed amount you plan to deposit every month.
2. Enter Annual Interest Rate (%): Provide the yearly interest rate offered for the RD.
3. Enter Investment Tenure (Years): Specify the duration for which you will make monthly deposits, in whole years.
4. Calculate: Click the "Calculate RD Maturity" button.

The calculator will display the "Total Principal Invested," "Total Interest Earned," and the final "Maturity Amount." This calculator assumes that the interest is compounded quarterly, which is a common practice for RDs.

📈 The Calculation Logic (Quarterly Compounding)

Calculating the maturity value of an RD with monthly installments and quarterly compounding involves a specific formula. A commonly used formula to approximate this is:

M = P × [((1 + r/400)(t×4) - 1) / (1 - (1 + r/400)(-1/3))]

Where:

• M = Maturity Amount
• P = Monthly Installment Amount
• r = Annual interest rate (as a percentage, e.g., 7 for 7%)
• t = Tenure of the RD in years

The Total Principal Invested is P × Tenure in Months.
The Total Interest Earned is M - Total Principal Invested.

💡 Frequently Asked Questions (FAQ)

What is a Recurring Deposit (RD)?

An RD is an investment product that allows you to deposit a fixed amount of money every month for a set period. It helps instill a habit of disciplined saving and earns a fixed rate of interest, which is typically compounded quarterly.

How is an RD different from a SIP (Systematic Investment Plan)?

The main difference is risk and return. An RD is a low-risk debt instrument with guaranteed, fixed returns. A SIP is a method of investing in mutual funds, where returns are market-linked (variable) and carry higher risk but also have the potential for higher returns.

Note: This formula is an approximation that models the effect of monthly contributions with interest compounded quarterly. Exact bank calculations might vary slightly due to their specific day-count conventions or rounding methods.
