If you’re looking for a safe, government-backed way to double your money, the Post Office’s Kisan Vikas Patra (KVP) could be the answer. With fixed returns and guaranteed maturity value, KVP is a popular choice among risk-averse investors in India. But how exactly does it work? How long does it take to double your money? And is it the best option for you? In this guide, we’ll break down everything you need to know about Kisan Vikas Patra, including how KVP helps double your investment, current interest rates (2025) and maturity period, the eligibility criteria, documents required, how to invest, tax implications, and safety, and some alternatives to KVP for better returns.
What is the Post Office Scheme to Double the Money?
The Post Office Scheme to Double the Money refers to Kisan Vikas Patra (KVP), a fixed-return savings scheme offered by India Post. Launched by the government of India, KVP is designed to help you grow your money predictably with zero market risk.
Some of its key features are as follows:
- Government-backed (100% safe).
- Fixed interest rate (revised quarterly).
- Money doubles at maturity (currently in 115 months).
- No maximum investment limit.
- Transferable & Nomination facility.
Unlike market-linked investments, KVP guarantees returns, making it ideal if you are more of a conservative investor.
Understanding Kisan Vikas Patra (KVP)
The Kisan Vikas Patra is a small savings scheme where your money grows at a predefined interest rate, compounded annually. The scheme’s name translates to “Farmer’s Growth Certificate”, but any Indian citizen (including minors) can invest.
How Does KVP Work?
- You invest a lump sum amount (minimum ₹1,000, no upper limit).
- The current interest rate (2025) is 7.5% p.a. (subject to quarterly revisions).
- Your money doubles in ~115 months (9.5 years).
- Premature withdrawal is allowed after 2.5 years with penalties.
Since KVP is backed by the Indian government, it’s one of the safest investment options available for you to consider.
How Much Time Does It Take to Double Your Money?
The doubling period depends on the current interest rate. As of 2025, KVP offers 7.5% per annum, which means;
| Investment | Maturity Period | Final Amount |
| ₹50,000 | 115 months (9.5 yrs) | ₹1,00,000 |
| ₹1,00,000 | 115 months | ₹2,00,000 |
| ₹5,00,000 | 115 months | ₹10,00,000 |
Note: The doubling period changes if interest rates are revised. Always check the latest rates before investing.
Interest Rate and Return Calculation
Current KVP Interest Rate (2025): 7.5% p.a.
(Compounded annually, revised quarterly by the government)
For instance,
- Investment: ₹1,00,000
- Rate: 7.5% p.a.
- Maturity Value (after 115 months): ₹2,00,000
Formula:
Maturity value = Principal* (1 + interest rate) ^number of years
Since KVP compounds annually, your money grows exponentially, ensuring doubling in the set period.
Eligibility and Documents Required for KVP
Who Can Invest?
- Indian adults (individually or jointly)
- Minors (through guardians)
- HUFs & Trusts – not allowed
Documents Needed
- Proof of Identity (Aadhaar, PAN, Voter ID)
- Proof of Address (Passport, Utility Bill, Aadhaar)
- Passport-size photo
- KVP Application Form
How to Invest?
1. Visit any India Post office.
2. Fill Form-1 and submit any necessary documents.
3. Deposit cash/cheque (minimum ₹1,000).
4. Receive KVP Certificate.
KVP cannot be bought online—only offline at post offices.
Is Kisan Vikas Patra a Safe Investment Option?
Yes! KVP is 100% secure because:
- Backed by the Indian Government.
- Fixed returns (no market risk).
- No default risk.
However, disadvantages include:
- No tax benefits (unlike PPF or NSC)
- Interest is taxable
- Lock-in period (2.5 years for premature withdrawal)
It is most suited for you if you are seeking capital protection over more returns.
Alternatives to Post Office Money-Doubling Schemes
If KVP’s 9.5-year doubling period feels too long, consider:
| Scheme | Returns | Lock-in | Tax Benefit? |
| National Savings Certificate (NSC) | 7.7% p.a. | 5 years | Yes (Sec 80C) |
| Public Provident Fund (PPF) | 7.1% p.a. | 15 years | Tax-free returns |
| Sukanya Samriddhi Yojana (SSY) | 8.2% p.a. | 21 years | Tax-free (girl child) |
| Fixed Deposits (FDs) | 6-7.5% p.a. | 1-10 yrs | Taxable |
For higher returns, you can consider debt mutual funds (6-8% post-tax) or equity-linked SIPs (10-12% long-term).
Conclusion
All things considered, investing in the various plans that India Post offers is typically a safe and secure way to grow and safeguard your money. The Indian government supports the initiatives, which offer substantial returns for a little investment. When considering the Post Office’s plan to double the money, Kisan Vikas Patra is the best choice. If you follow the specified rules, you can easily double your investment in 9.5 years and take the money out early in an emergency.
But for elderly citizens, the elderly Citizens’ Savings Scheme offers an additional way to double your money. To prevent problems with the investment of your hard-earned money, be sure to understand all of the schemes’ terms, conditions, and benefits.
