Rd Calculator for 15 Years

Reviewed by Calculator Editorial Team

Recurring Deposits (RDs) are a popular savings instrument in many countries, offering fixed interest rates over a set period. This calculator helps you determine how much you'll have after 15 years of regular monthly deposits with compound interest.

How to Use This Calculator

To calculate your 15-year RD maturity amount:

  1. Enter your monthly deposit amount in the first field
  2. Select your annual interest rate (typically 6-8% in many countries)
  3. Choose whether the interest is compounded monthly or annually
  4. Click "Calculate" to see your projected maturity amount

The calculator will show you the total amount you'll receive after 15 years, including all interest earned. You'll also see a chart showing how your savings grow over time.

How Recurring Deposits Work

Recurring Deposits are time deposits where you make regular fixed payments (usually monthly) to a bank account. The bank credits these amounts to your account and pays interest on the total balance at regular intervals.

Formula Used

The future value (FV) of a series of recurring deposits is calculated using the formula:

FV = P × [((1 + r/n)^(nt) - 1) / (r/n)] × (1 + r/n)

Where:

  • P = monthly deposit amount
  • r = annual interest rate (in decimal)
  • n = number of times interest is compounded per year
  • t = time in years

The key advantages of RDs include:

  • Fixed interest rates for the entire term
  • Regular interest payouts
  • Guaranteed returns
  • Tax benefits in some countries

Worked Example

Let's calculate a 15-year RD with these assumptions:

  • Monthly deposit: $1,000
  • Annual interest rate: 7%
  • Compounded monthly

Calculation Steps

1. Convert annual rate to monthly: 7% ÷ 12 = 0.5833% or 0.005833 in decimal

2. Number of payments: 15 years × 12 = 180 months

3. Apply the formula: FV = 1000 × [((1 + 0.005833)^180 - 1) / 0.005833] × (1 + 0.005833)

4. The calculation yields approximately $272,350.72

This example shows how compound interest significantly grows your savings over time. The total interest earned would be $272,350.72 - $180,000 = $92,350.72.

Frequently Asked Questions

What is the difference between RD and FD?
Recurring Deposits (RD) involve regular fixed payments, while Fixed Deposits (FD) are single lump-sum amounts. RDs offer more flexibility in terms of deposit timing and typically have lower interest rates than FDs.
Can I withdraw money from an RD before maturity?
Most RDs have a lock-in period where withdrawals are not allowed. Check your bank's terms and conditions for specific rules regarding premature withdrawals.
How is RD interest calculated?
RD interest is typically calculated on the total balance, compounded monthly or annually, depending on the bank's policy. The interest is usually credited to your account at regular intervals.
