In India, many risk-averse investors invest in a PPF to create a corpus for post-retirement life. The PPF was introduced in India in 1968 to encourage the salaried employees to invest a small amount every month and earn returns on it. This savings-cum-investment option allows you to build a retirement corpus throughout the working years while saving on the annual taxes. Read on to know how you can plan your investments efficiently with the PPF calculator.

A PPF Calculator is an online, free-to-use tool that helps you perform even the most complicated PPF-related calculations with ease. You can use the tool to calculate the expected annual returns, the overall returns you can expect on maturity, how much you must contribute towards the PPF account to reach your goal, etc.

The calculation formula that a PPF calculator uses is as follows:

● M = P [ ( { (1 + i) ^ n } - 1 ) / i ]
Where:
● M = Maturity benefit
● P = Annual instalments
● i = Interest rate
● n = Number of years

Using the PPF Calculator is easy; you must enter the following data in the respective fields:

• Investment tenure

  - The minimum term is 15 years, with a provision to extend in the blocks of five years.

• Deposit frequency

  - You have the flexibility to choose the frequency of deposit, it can be monthly, quarterly, every six months or annually.

• Deposit amount

  - You must enter the annual deposit amount. For example, if you wish to invest Rs. 1000 every month, then your yearly deposit amount will be Rs. 12,000

• Interest rate

  - The central government decides the interest rate, but it is generally in the range of 7% to 8%.

Once you enter the above details, click on the ‘calculate’ button, and you will get detailed information about the maturity amount, the interest earned, the total amount invested, etc. instantly.

Like the traditional investment option, PPF is a fixed-interest investment. The central government announces the interest rate on PFF every quarter. If you have invested in PPF or wish to add the investment in your portfolio, you must understand the interest calculation process to get maximum returns from your investment.
Typically, the financial organisations calculate the PPF on the lowest balance between the fifth and last days of every month. Any amount invested on or before 5th is considered for interest payment. Hence, it advisable that you make the deposits in the PPF account between 1st and the 5th day of the month to calculate the interest for that respective month.
The interest rates offered by PPF ranges between 7% to 8%. The interest rate for the first quarter of the year in 2020, i.e., 1st April to 30th June, was fixed at 7.1%, and the interest rate for January 2020 to March 2020 was 7.9%.

PPF offers a wide range of benefits in terms of assured returns, taxation, loan facility, withdrawal flexibility, etc. Let us look at the benefits in detail.

Fixed interest rate

Many modern investors would argue that fixed-rate limits the investor’s capital growth, but it assures fixed returns and has no underlying risk of market movements. The central government revises the PPF interest rate every quarter, and historically it has been around 7% to 8%, and it tends to fluctuate slightly depending on the overall economic situation.
Another significant feature is that the interest is compounded annually. Furthermore, fixed interest means that you know the exact returns at the start of the investment, and you can plan your finances accordingly. You can use the PPF calculator to know the accurate returns and the interest you may earn at the end of the investment tenure.

Extension of investment tenure

Typically, the PPF scheme is a long-term investment with a tenure of 15 years. But, if you do not want to use the accumulated corpus after the end of the investment term, you can extend the investment for five years.

Investment security

Being a government-backed investment scheme, you can be assured of the safety and security of your investments in PPF. Generally, risk-averse investors prefer investing in this fund. Additionally, the interest earned is backed by sovereign guarantee making a safer investment than the interest earned from bank deposits.

Loan against PPF investment

In the event of any emergency, you can avail of a loan against the PPF investment at an affordable interest rate. However, you can avail of the loan only from the third to the sixth year of opening the account. Loan against PPF is beneficial if you are looking for a short-term credit without pledging any collateral.
The maximum amount you can borrow against the PPF should not be more than 25% of the balance at the end of the preceding financial year. The repayment tenure is 36 months from the first day of the month succeeding the month in which you availed the loan.

Many people in India invest in PPF to get the tax benefit and reduce their annual tax liability. The PPF follows the EEE (Exempt, Exempt, Exempt) taxation model, which implies that the amount you invest towards the PPF account, the interest earned from your investment, and the maturity amount you get at the end of the investment term are exempted from tax.
The investments in PPF account are eligible for a tax deduction to a maximum limit of Rs. 1.5 lakhs in a financial year under Section 80C of the IT Act.

In a financial year, you are allowed to invest up to Rs. 1.5 Lakh. You should also check how much you can invest in order to get tax benefit under Section 80C.

If you want to invest in a safe Government investment to accumulate funds for life after retirement, then PPF is a great option.
But you must keep in mind that PPF has a lock-in period of 15 years. However, PPF provides you with the option of partial withdrawal.
Furthermore, PPF is a low-risk investment as it’s supported by the Government. Thus, if you’re a low-risk investor, then you should consider investing in PPF.
PPF will suit you if your investment goal is to ensure a financially secure life after retirement. By investing in PPF, you can also avail tax benefits.
