Module C: Formula & Methodology Behind the Calculator
The calculator employs Kotak Mahindra Bank’s exact 2018 recurring deposit calculation formula, which uses quarterly compounding as mandated by RBI guidelines that year.
Core Calculation Formula:
The maturity amount (A) is calculated using:
A = P × [(1 + r/n)^(nt)] × (1 + r/n) Where: P = Monthly deposit amount r = Annual interest rate (in decimal) n = Number of compounding periods per year (4 for quarterly) t = Tenure in years
Step-by-Step Computation Process:
- Convert Annual Rate: Divide annual rate by 4 (quarterly compounding)
- Calculate Periods: Multiply tenure in years by 4 (number of quarters)
- Compute Growth Factor: (1 + r/n)^(nt)
- Apply Annuity Formula: Multiply by [(1 + r/n) × (growth factor – 1)]/r
- Final Amount: Multiply by monthly deposit (P)
2018-Specific Adjustments:
- TDS Deduction: 10% on interest if exceeding ₹10,000 (Section 194A)
- Premature Withdrawal: 1% penalty on interest for early closure
- Senior Citizen Bonus: Additional 0.5% across all tenures
- Digital RD Bonus: Extra 0.10% for online bookings (introduced June 2018)
The calculator automatically applies these 2018-specific rules when performing computations, including the exact day-count convention used by Kotak (30/360 method for interest calculation).
