Module C: Formula & Calculation Methodology
1. Fixed Deposit (FD) Calculation
Uses standard compound interest formula:
A = P × (1 + r/n)nt
Where:
A = Maturity amount
P = Principal
r = Annual interest rate (decimal)
n = Compounding frequency per year
t = Time in years
2. Recurring Deposit (RD) Calculation
Special formula accounting for monthly deposits:
M = R × [(1 + i)n – 1] × (1 + i)/i
Where:
M = Maturity value
R = Monthly deposit
i = Periodic interest rate (annual rate/12)
n = Total months
3. Senior Citizen Savings Scheme (SCSS)
Unique 5-year term with quarterly payout option:
Quarterly Interest = (P × r/4) × (1 – t)
t = Tax rate (20% TDS if interest > ₹50,000/year)
Module D: Real-World Calculation Examples
Example 1: 5-Year Post Office FD (₹1,00,000 at 7.5%)
Inputs: Scheme=FD, Amount=₹1,00,000, Tenure=5 years, Rate=7.5%, Compounding=Quarterly
Calculation:
A = 100000 × (1 + 0.075/4)4×5 = ₹144,701
Interest Earned: ₹44,701 (44.7% of principal)
Example 2: Monthly RD (₹5,000/month for 5 years at 6.7%)
Inputs: Scheme=RD, Amount=₹5,000, Tenure=5 years, Rate=6.7%
Calculation:
M = 5000 × [(1 + 0.067/12)60 – 1] × (1 + 0.067/12)/(0.067/12) = ₹3,61,784
Total Deposited: ₹3,00,000 | Interest: ₹61,784
Example 3: SCSS with Quarterly Payout (₹15,00,000 at 8.2%)
Inputs: Scheme=SCSS, Amount=₹15,00,000, Rate=8.2%, Payout=Quarterly
Annual Interest: ₹15,00,000 × 8.2% = ₹1,23,000
Quarterly Payout: ₹30,750 (before TDS)
Maturity Amount: ₹15,00,000 (principal returned after 5 years)

Module G: Interactive FAQ
Is post office FD better than bank FD?
Post office FDs offer 0.5-1% higher rates than most banks (7.5% vs 6.5-7% in banks) with sovereign guarantee. However, banks provide:
- Online account management
- Auto-renewal options
- Sweep-in facilities
Choose post office for safety and higher returns, banks for convenience and liquidity.
What happens if I miss an RD installment?
For post office RD:
- You can pay the missed installment with a ₹1 late fee per ₹100 within the same calendar month
- After 4 consecutive defaults, the account becomes discontinued
- Discontinued accounts can be revived within 2 months by paying all arrears + fees
- If not revived, you’ll get the deposit amount without interest for the defaulted period
Pro Tip: Set up auto-debit from your savings account to avoid defaults.
Can NRIs invest in post office schemes?
No, post office schemes are only for resident Indians. NRIs cannot:
- Open new accounts
- Continue existing accounts (must close before becoming NRI)
- Joint accounts with residents
Alternatives for NRIs:
- NRE/NRO fixed deposits (banks)
- Mutual funds (through PIS)
- Government securities
Exception: If you become NRI after opening a PPF account, you can continue until maturity without further contributions.
