Formula & Methodology Behind the Calculator
The calculator uses scheme-specific compounding formulas as prescribed by the Ministry of Finance:
1. For Compounding Schemes (PPF, SSY, TD, RD):
A = P × (1 + r/n)^(nt)
- A = Maturity amount
- P = Principal amount
- r = Annual interest rate (decimal)
- n = Number of times interest compounds per year
- t = Time in years
2. For Non-Compounding Schemes (MIS, SCSS):
Simple Interest = (P × r × t) / 100
Key Assumptions:
- Interest rates remain constant throughout the tenure
- No partial withdrawals are made (except where scheme rules permit)
- Investments are made at the beginning of each period for RD
- Tax implications are not factored (consult a CA for tax planning)

Interactive FAQ
What is the safest post office scheme with highest returns?
For 2024, the Sukanya Samriddhi Yojana (SSY) offers the highest rate at 8.2% with sovereign guarantee. For senior citizens, SCSS at 8.2% is equally safe and lucrative. Both schemes are backed by Government of India and considered zero-risk investments.
Can I open multiple post office accounts in same scheme?
Rules vary by scheme:
- PPF: Only 1 account per individual (joint accounts not allowed)
- SSY: 1 account per girl child (max 2 accounts per family)
- SCSS: Only 1 account per senior citizen (spouses can have separate accounts)
- MIS/TD/RD: Multiple accounts allowed, but total investment limits apply
Attempting to open multiple accounts in restricted schemes may lead to account freezing as per Post Office Savings Account Rules, 1981.
How is post office interest calculated – simple or compound?
Calculation methods by scheme:
| Scheme | Calculation Method | Compounding Frequency |
|---|---|---|
| PPF | Compound Interest | Annually |
| SSY | Compound Interest | Annually |
| SCSS | Simple Interest | Quarterly (paid out) |
| MIS | Simple Interest | Monthly (paid out) |
| TD (1-3Y) | Simple Interest | Quarterly (compounded) |
| TD (5Y) | Compound Interest | Quarterly |
| RD | Compound Interest | Quarterly |
Note: For compounding schemes, interest is added to principal for next period’s calculation. For simple interest schemes, payouts are credited to your linked account.
What happens if I withdraw from post office schemes prematurely?
Premature withdrawal rules (as per India Post guidelines):
- PPF: Allowed after 5 years with 1% interest penalty
- SSY: Allowed only after girl child turns 18 (50% withdrawal for education)
- SCSS: Allowed after 1 year with penalties:
- 1-2 years: 1.5% of deposit
- 2-5 years: 1% of deposit
- MIS/TD: No premature withdrawal before 1 year. After 1 year:
- 1-3 years: 2% penalty on principal
- 3-5 years: 1% penalty on principal
- RD: No withdrawal before maturity. Account can be closed prematurely with simple interest instead of compound interest
Are post office schemes better than bank FDs?
Comparison between Post Office schemes and Bank Fixed Deposits:
| Parameter | Post Office Schemes | Bank FDs |
|---|---|---|
| Safety | ⭐⭐⭐⭐⭐ (Sovereign guarantee) | ⭐⭐⭐⭐ (DICGC insured up to ₹5 lakh) |
| Interest Rates | 7.1% – 8.2% (2024) | 5.5% – 7.5% (varies by bank) |
| Tax Benefits | 80C for PPF/SSY/5Y TD | 80C for 5Y tax-saver FDs |
| Liquidity | Limited (scheme-specific rules) | Better (loan against FD option) |
| Digital Access | Improving (IPPB app, Internet banking) | Advanced (net banking, mobile apps) |
| Maximum Limit | Scheme-specific (₹1.5L-₹30L) | No limit (but ₹5L DICGC cover) |
Verdict: Post office schemes win on safety and rates, while bank FDs offer better liquidity and digital experience. For risk-averse investors, post office schemes are preferable despite slightly less convenience.
