Interest is defined as the fee paid by a borrower of assets to the owner as a form of compensation for the use of the assets. It is the price paid for the use of borrowed money or the money owed by the deposited funds.

Principal is the amount that is taken initially or invested initially.

Simple interest is calculated only based on the principal amount or the portion of the simple interest that remains unpaid.

Simple Interest = (P*N*R)/100

Here, P represents the principal amount

N represents the number of years

R represents the rate of interest

Here, P represents the principal amount

N represents the number of years

R represents the rate of interest

The sum of principal and simple interest is the total amount you need to pay.

Total Amount= Principle + Simple Interest

**Let the total amount be represented as ‘A’ then,**

A = P + S.I

A= P + (P*N*R)/100

Let r = R/100 which represents the rate of interest in decimal form then

A = P + (P*N*r)

A=P*(1 + N*r) - this is the formula used to any parameter in this equation

For total amount, A=P*(1 + N*r)

For principle amount, P=A/ (1 + N*r)

For rate of interest, r=(1/t)*(A/P - 1)

For rate of interest in percentage, R = r * 100

For time period, t = (1/r)*(A/P - 1)

A = P + S.I

A= P + (P*N*R)/100

Let r = R/100 which represents the rate of interest in decimal form then

A = P + (P*N*r)

A=P*(1 + N*r) - this is the formula used to any parameter in this equation

For total amount, A=P*(1 + N*r)

For principle amount, P=A/ (1 + N*r)

For rate of interest, r=(1/t)*(A/P - 1)

For rate of interest in percentage, R = r * 100

For time period, t = (1/r)*(A/P - 1)

- While taking a loan, choose the bank or source of loan that collects simple interest rather than compound interest.
- While lending money or making an investment, choose the method or plan that gives you compound interest rather than simple interest.

Note: Simple interest is always paid in the principal invested and the accrued interest is not added to the principle.

For example, if we have Rs. 1000 invested at 10% simple interest per annum for 5 years, you will receive Rs 100 as interest each year for the 5 years of investment.

Simple Interest

Year | Principle | Interest | Amount at the end |
---|---|---|---|

1 | 1000 | 1000*10%=100 | 1,100 |

2 | 1000 | 1000*10%=100 | 1,200 |

3 | 1000 | 1000*10%=100 | 1,300 |

4 | 1000 | 1000*10%=100 | 1,400 |

5 | 1000 | 1000*10%=100 | 1,500 |

So at the end of the 5th year, the amount we get is 1,500.

Simple interest usually applies to short-term personal loans where the time period is very short. Note that most mortgages do not use simple interest. Planning for a loan and want to estimate a rough EMI that you many have to pay? Use our EMI calculator.

Some banks use simple interest method for mortgages for bi-weekly payment plans. Bi-weekly plans generally help consumers pay off their loans early because the borrowers make two extra payments a year. This will save interest over the tenure of the loan by clearing off the principal faster.

Some limitations of simple interest:

- Simple interest is ignoring the compound where the interest on interest does not have to be paid for.
- With simple interest, you don’t really get anything when you lend money.
- Simple interest is usually used for small loans that can be paid back quickly.
- Simple interest is money that is added to a principal amount that you have to pay over a period of time and it does not change in the total period of time. This is disadvantageous if the simple interest percentage is higher.
