PPF Calculator 2020 – Interest Rate & Maturity Amount
Comprehensive Guide to PPF Calculator 2020 Interest Rates
Module A: Introduction & Importance of PPF Calculator 2020
The Public Provident Fund (PPF) remains one of India’s most popular long-term savings schemes, offering guaranteed returns with tax benefits under Section 80C of the Income Tax Act. The PPF calculator for 2020 interest rates helps investors precisely determine their maturity amounts based on the 7.1% interest rate that was applicable during that financial year.
Understanding the PPF interest calculation is crucial because:
- It helps in accurate financial planning for long-term goals like retirement or education
- Allows comparison with other investment options like mutual funds or fixed deposits
- Enables tax-efficient wealth creation with compounding benefits
- Provides clarity on the exact maturity amount you’ll receive after 15 years
The 2020 PPF interest rate of 7.1% (reduced from 7.9% in previous years) reflects the government’s monetary policy decisions. This calculator incorporates the exact compounding formula used by banks to compute your returns annually.
Module B: How to Use This PPF Calculator
Our interactive PPF calculator is designed for both beginners and experienced investors. Follow these steps for accurate results:

Pro Tip: Use the calculator to compare different investment amounts. For example, see how increasing your annual contribution from ₹50,000 to ₹1,00,000 nearly doubles your maturity amount over 15 years.
Module C: PPF Calculation Formula & Methodology
The PPF maturity amount is calculated using the compound interest formula with annual compounding. The exact formula used in our calculator is:
A = P * [( (1 + r)^n – 1 ) / r] * (1 + r)
Where:
A = Maturity Amount
P = Annual Investment
r = Annual Interest Rate (7.1% or 0.071 for 2020)
n = Investment Period in Years
Key aspects of the calculation:
- Interest is compounded annually and credited to your account at the end of each financial year
- The minimum investment is ₹500 per year, while the maximum is ₹1,50,000
- Partial withdrawals are allowed from the 7th year onwards
- Loans against PPF are available from the 3rd to 6th year
- The interest rate is set by the government quarterly but remains fixed for the entire tenure once you open the account
For monthly investments, the calculator converts your monthly amount to an annual figure before applying the formula. The same methodology applies to quarterly investments.

Table 2: PPF vs Other Fixed Income Instruments (2020)
| Instrument | Interest Rate (2020) | Tax Benefit | Lock-in Period | Risk Level | Liquidity |
|---|---|---|---|---|---|
| PPF | 7.1% | EEE (Exempt-Exempt-Exempt) | 15 years | Very Low | Partial after 7 years |
| Bank FD (1-5 years) | 5.5%-6.5% | Taxable | 1-5 years | Low | Moderate |
| Senior Citizen Savings Scheme | 7.4% | Taxable | 5 years | Low | Moderate |
| NSC (National Savings Certificate) | 6.8% | Section 80C | 5 years | Very Low | Low |
| KVP (Kisan Vikas Patra) | 6.9% | No | 2.5 years | Very Low | Low |
| Sukanya Samriddhi Yojana | 7.6% | EEE | Until girl turns 21 | Very Low | Partial after 18 years |
| Debt Mutual Funds | 6%-8% | Taxable (LTCG) | None | Moderate | High |
Analysis shows that despite the 2020 rate cut, PPF remains competitive due to:
- Complete tax exemption (EEE status)
- Sovereign guarantee (zero risk)
- Flexible contribution amounts (₹500-₹1,50,000)
- Loan facility available from 3rd to 6th year
- Partial withdrawal option after 7 years
Module F: 15 Expert Tips to Maximize Your PPF Returns
Strategic Investment Tips
- Invest Early in the Financial Year: PPF interest is calculated on the minimum balance between the 5th and last day of each month. Depositing before the 5th of April ensures you earn interest for the entire year.
- Maximize Your Contribution: Always aim for the ₹1,50,000 annual limit to fully utilize the tax benefit under Section 80C.
- Use the 5-Year Extension Wisely: After 15 years, you can extend your PPF account in 5-year blocks without fresh deposits, allowing your corpus to keep growing tax-free.
- Ladder Your Investments: Open multiple PPF accounts for family members (spouse, children) to increase your total tax-free investment capacity.
- Time Your Withdrawals: If you need funds, withdraw in the year when your income is lowest to minimize tax impact on the interest component.
Tax Optimization Strategies
- Combine PPF with ELSS funds to diversify your Section 80C investments while maintaining liquidity
- Use PPF for children’s education planning as the 15-year tenure often aligns with higher education timelines
- If you’re in the highest tax bracket (30%), PPF’s EEE status effectively gives you a 9.28% pre-tax equivalent return (7.1% post-tax)
- Consider transferring matured PPF funds to Senior Citizen Savings Scheme (if eligible) for higher post-retirement returns
Advanced Techniques
- Use the PPF account as collateral for loans (available from 3rd to 6th year) instead of breaking the investment
- For business owners, contribute during high-profit years to reduce taxable income
- Monitor government notifications for rate changes (typically announced in March for the next financial year)
- Use the calculator to model different scenarios – see how increasing your investment by just ₹10,000 annually adds ₹2-3 lakhs to your maturity amount
- Consider opening accounts in different post offices/banks to manage multiple PPF accounts efficiently
Module G: Interactive PPF FAQ
Is the 7.1% PPF interest rate for 2020 still applicable if I opened my account earlier?
The PPF interest rate is determined by the government and applies to all existing accounts uniformly. When the rate changes (like the reduction to 7.1% in 2020), it affects all PPF accounts regardless of their opening date. However, the rate remains fixed for the entire duration once you open the account in a particular financial year.
Can I have more than one PPF account in my name?
No, the PPF rules strictly prohibit an individual from opening more than one PPF account in their name. However, you can open separate accounts for your minor children and act as a guardian for those accounts. The total contribution across all accounts where you’re the primary account holder cannot exceed ₹1,50,000 per financial year.
What happens if I don’t deposit the minimum ₹500 in a year?
If you fail to deposit the minimum ₹500 in any financial year, your PPF account becomes inactive. To reactivate it, you need to pay a penalty of ₹50 for each year of default along with the minimum deposit of ₹500 for each inactive year. The interest for the inactive years will not be credited until the account is reactivated.
How is PPF interest calculated monthly if I make regular deposits?
PPF interest is actually calculated annually, but it’s based on the minimum balance in your account between the 5th and the last day of each month. For example, if you deposit ₹10,000 on the 10th of every month, you’ll only earn interest on that amount from the following month. To maximize interest, deposit your contribution before the 5th of each month.
Can I withdraw money from my PPF account before 15 years?
Partial withdrawals are permitted from the 7th financial year onwards. You can withdraw up to 50% of the balance at the end of the 4th year preceding the year of withdrawal or the end of the preceding year, whichever is lower. For example, in the 7th year, you can withdraw up to 50% of your balance at the end of the 3rd year.
What are the tax benefits of PPF in 2020 compared to other instruments?
PPF offers triple tax benefits (EEE status):
1. Exempt on investment (up to ₹1,50,000 under Section 80C)
2. Exempt on interest earned
3. Exempt on maturity amount
This makes it superior to most fixed income instruments where interest is taxable. For someone in the 30% tax bracket, a 7.1% PPF return is equivalent to a 10.14% taxable return from other instruments.
How does the PPF calculator handle the compounding of interest?
Our calculator uses the exact compound interest formula that PPF accounts follow. The interest is compounded annually and added to your principal at the end of each financial year. The formula accounts for this annual compounding effect over your entire investment period. For monthly contributions, the calculator first converts them to an annual equivalent before applying the compounding formula.
