Banks, post offices and Non-Banking Financial Companies (NBFCs) offer fixed deposits (FD) in India. Among the three, NBFCs or corporate companies offer higher interest rates on their fixed deposit schemes to attract customers. For instance, Shriram Fixed Deposit offers interest of up to 9.20%* p.a. inclusive of an 0.50%* p.a. for senior citizens and 0.10%* p.a. for women depositors.

However, corporate companies like Shriram Finance calculate their FD interest rates based on various factors. Let's have a look at these factors and understand how to calculate interest for FD schemes.

## Factors Affecting Corporate FD Interest Rates

The corporate FD rates depend on the following factors:

## Type of FD

Many corporate companies offer two types of deposit schemes, and the interest rates are different for each of these schemes.

**Cumulative FD -**A cumulative FD is one where the interest you earn every year is reinvested in the scheme. This allows you to earn additional interest on the interest already earned. On maturity, the aggregate interest and the deposited amount is paid back in a lump sum.**Non-cumulative FD -**Under this scheme, the interest you earn is paid instead of getting reinvested. Thus, you can create a regular source of income with non-cumulative FDs and get the deposit amount back on maturity.

## Deposit tenure

The interest rate also depends on the deposit tenure. Usually, as the deposit tenure increases, so does the interest rate.

## Age of the depositor

Senior citizens, i.e., individuals aged 60 years and above, enjoy higher interest rates on their deposits. So, if you are a senior citizen or you open an FD for your senior citizen parents, you can earn higher interest rates.

## Gender of the depositor

Many corporate companies allow higher interest rates for women depositors. For instance, Shriram Fixed Deposit offers its female depositors a 0.10% additional interest benefit with interest rate running up to 9.20%* p.a.

## Renewing an existing deposit

If you renew the FD on maturity, you might earn an additional interest rate on such renewals. Many corporate companies like Shriram Finance offer additional interest rates on renewing the FD scheme post-maturity. Depositors can avail an additional 0.25%* p.a. upon maturity of their fixed deposit.

So, when you choose a corporate FD, these factors determine the interest your deposit will attract.

## Interest Calculation Formula for Corporate Fixed Deposits

Now that you know the factors that affect your corporate fixed deposit interest rates, let's understand **how to calculate FD interest**.

You can calculate the interest with an **FD calculation formula**.

Also, in the case of compound interest, the frequency of compounding is considered.

Here's a look at the **interest calculation formula** for corporate fixed deposits:

- Simple interest

Simple interest is usually calculated in the case of non-cumulative deposits which pay the interest as and when it is earned. The **FD calculation formula**, in this case, is as follows:

Interest earned = (P X R X T) / 100

In the formula, the values are as follows:

- P - The amount that you deposit
- R - The rate of interest, expressed as a percentage
- T - Tenure, expressed in years

For example, say you deposit ₹1 lakh in a non-cumulative FD scheme where the interest rate is 7%, and the deposit tenure is 2 years. Here's how the interest will be calculated and paid:

Period | Interest calculated and paid annually | Interest calculated and paid half-yearly |
---|---|---|

After 6 months | (₹1 lakh X 7% X 1 year) / 100 = ₹7,000 | ₹1 lakh X 7% X 0.5 years) / 100 = ₹3,500 |

After 18 months | NA | ₹1 lakhs X 7% X 0.5 years) / 100 = ₹3,500 |

After 24 months | (₹1 lakhs X 7% X 1 year) / 100 = ₹7,000 | ₹ 1 lakh X 7% X 0.5 years) / 100 = ₹3,500 |

In non-cumulative fixed deposit, the interest rate differs depending on the payout period. To get accurate interest rates of Shriram Unnati Fixed Deposit, use our FD calculator.

**Compound interest**

This interest is applicable in cumulative FDs. In the case of compound interest, the interest earned is reinvested, and future interest is earned on the same.

For instance, consider the following example:

Period | Deposit amount | Interest rate | Interest earned | Total deposit value |
---|---|---|---|---|

After the end of 1 year | ₹1 lakh | 7% | ₹7,000 | ₹1,07,000 |

After the end of the 2nd year | ₹1,07,000 | 7% | ₹7,490 | ₹1,14,490 |

To make calculations easier, you can use the compound interest formula for calculating the FD amount on maturity. The formula is:

Maturity amount = P X {(1 + R/N) ^ T X N}

In the formula, the values are:

- P - The amount that you deposit
- R - The rate of interest, expressed in decimals
- T - Tenure, expressed in years
- N - The compounding frequency, i.e., whether the interest is compounded annually, half-yearly or quarterly

If you deduct the deposited amount from the maturity amount, you will get the interest earned.

To understand the compound interest calculation using the formula, consider the following examples:

Cases | Deposit details | Interest rate | Compounding frequency | Maturity amount | Interest earned |
---|---|---|---|---|---|

Case 1 | ₹1 lakh deposited for 4 years | 7% per annum | Annual | P X {(1 + R/N) ^ T X N} = ₹1 lakh X {(1 + 0.07/1) ^ 4 X 1} = ₹1,31,080 | ₹1,31,080 - ₹1,00,000 = ₹31,080 |

Case 2 | ₹1 lakh deposited for 4 years | 7% per annum | Half-yearly (compounding frequency is 2) | P X {(1 + R/N) ^ T X N} = Rs.1 lakh X {(1 + 0.07/2) ^ 4 X 2} = ₹1,31,681 | ₹1,31,681 - ₹1,00,000 = ₹31,681 |

Case 3 | ₹1 lakh deposited for 4 years | 7% per annum | Quarterly (compounding frequency is 4) | P X {(1 + R/N) ^ T X N} = ₹1 lakh X {(1 + 0.07/4) ^ 4 X 4} = ₹1,31,993 | ₹.1,31,993 - ₹1,00,000 = ₹31,993 |
