How To Calculate Interest Earned During A Bank Statement Period

Calculating Interest Rates on a Bank Loan


Calculating the interest earned in your checking or savings accounts during a bank statement period can help you prepare an accurate budget. You don’t necessarily need to use a special checking account interest calculator to get a quick result. By becoming familiar with the two main interest formulas, you can quickly calculate interest earned with a basic scientific calculator.

How To Calculate Monthly Interest

The Balance 2020

Calculating interest month-by-month is an essential skill. You often see interest rates quoted as an annualized percentageeither an annual percentage yield or an annual percentage rate but its helpful to know exactly how much that adds up to in dollars and cents. We commonly think in terms of monthly costs.

For example, you have monthly utility bills, food costs, or a car payment. Interest is also a monthly event, and those recurring interest calculations add up to big numbers over the course of a year. Whether youre paying interest on a loan or earning interest in a savings account, the process of converting from an annual rate to a monthly interest rate is the same.

Calculation Of Interest On Fixed Deposit & In Case Of Pre

Fixed deposits generally pays higher interest than savings account. But it comes with a lock-in period. If you withdraw before the fixed tenure then a penalty is levied on the withdrawal, i.e. you will receive the amount after deduction of a small percentage of it, which generally ranges from 0.5%-1%.

The formula for calculation of interest is,

Interest= Principal*Rate of interest

Lets understand this better with an example,

Ms. Ayushi has invested Rs. 100,000 in fixed deposit for a period of 1 year, earning an interest of 8% p.a. . The 6 month interest rate is 6%. Premature withdrawal penalty is 0.5%.

Case I: Ms. Ayushi withdraws after 1 year i.e. at maturity. Case II: Ms. Ayushi withdraws after 6 months i.e. premature withdrawal

In the first case, where Ms. Ayushi completes the tenure of the F.D., she will earn,

Interest: 100,000*8%= 8000

Total Maturity value: 100,000+8000= Rs. 1,08,000

Thus, at the end of 1 year, Ms. Ayushi will receive Rs. 1,08,000

In the second case, Ms. Ayushi has withdrawn before the completing tenure of 1 year. She broke her F.D. after 6 months. In this case, the interest will be calculated differently.

Initially, when she had made the deposit, she had promised to keep the deposit for a period of 1 year for which the bank had offered 8% interest. But now that she is withdrawing earlier, the bank will pay her the revised interest which is applicable for a 6 month fixed deposit. In our case, it is 6%.

How To Calculate Simple Interest In A Savings Account

You can calculate simple interest in a savings account by multiplying the account balance by the interest rate by the time period the money is in the account.

Here’s the simple interest formula: Interest = P x R x N.

P = Principal amount .

R = Interest rate .

N = Number of time periods .

Say you have a savings account with $10,000 that earns 1% interest per year. Expressed as a decimal, the interest rate is 0.01, so the formula would be:

Interest = $10,000 x 0.01 x 1, which equals $100.

Interest rates in even the best savings accounts are lower than 1%, however. In fact, the national average savings rate is 0.06%. You can use NerdWallets savings calculator to figure how much interest you could earn with different rates and time periods.

Heres another example: If the $10,000 deposit is in an account that earns only 0.10% interest per year, the interest rate would be expressed as 0.001. In this case, the calculation would be:

Interest = $10,000 x 0.001 x 1.

Interest = $10.

Practically speaking, this formula is best for calculating roughly how much interest your money can earn in a savings account.

To determine precisely how much interest you could earn in a savings account, youll want to consider the effect of compounding.

Calculation Of Interest On Savings Account

According to the guidelines rolled out by the Reserve Bank of India in 2010, the interest on savings account is calculated on daily outstanding balance. It means that you earn interest on the bank balance you have at the end of each day.

The formula for the same is as follows,

Interest on savings account= Daily balance*Rate of interest*

Lets try to understand it better with the help of an example.

Say, Mr. Anupam has Rs. 100,000 in his account on Day 1. He withdraws Rs. 50,000 after 7 days. And then deposits Rs. 30,000 on the 14th day. And thereafter there are no transactions. Assuming the rate of interest is 4%, lets look at the interest he has earned for the month of January.


Here, the interest will be calculated as follows,

From 1.1.2018- 6.1.2018 the outstanding balance was Rs. 100,000. Thus, the interest will be calculated on Rs. 100.000 for 7 days, which is,

100,000*4/100*7/365= 76.71

From 7.1.2018 to 14.1.2018 the outstanding balance was Rs. 50,000, upon which the interest shall be calculated for the period of 7 days,

50,000*4/100*7/365= 38.35

From 14.1.2018- 31.1.2018 the outstanding balance was Rs. 80,000, on which the interest for 18 days shall amount to,

80,000*4/100*18/365= 157.8

Thus, the total interest earned for the month of January will be,

76.71+38.35+157.8= 272.87

Interest earned for the month of January

Outstanding Balance
Total interest earned 272.87

Monthly Interest Rate Calculation Example

To calculate a monthly interest rate, divide the annual rate by 12 to reflect the 12 months in the year. You’ll need to convert from percentage to decimal format to complete these steps.

Example: Assume you have an APY or APR of 10%. What is your monthly interest rate, and how much would you pay or earn on $2,000?

  • Convert the annual rate from a percent to a decimal by dividing by 100: 10/100 = 0.10
  • Now divide that number by 12 to get the monthly interest rate in decimal form: 0.10/12 = 0.0083
  • To calculate the monthly interest on $2,000, multiply that number by the total amount: 0.0083 x $2,000 = $16.60 per month
  • Convert the monthly rate in decimal format back to a percentage : 0.0083 x 100 = 0.83%
  • Your monthly interest rate is 0.83%
  • Want a spreadsheet with this example filled in for you? See the free Monthly Interest Example spreadsheet, and make a copy of the sheet to use with your own numbers. The example above is the simplest way to calculate monthly interest rates and costs for a single month.

    You can calculate interest for months, days, years, or any other period. Whatever period you choose, the rate you use in calculations is called the periodic interest rate. Youll most often see rates quoted in terms of an annual rate, so you typically need to convert to whatever periodic rate matches your question or your financial product.

    You can use the same interest rate calculation concept with other time periods:

    The Rate in Simple Interest refers to Rate of Interest of Loans or Rate at which you have lent money to someone or invested your money in any investment scheme.

    What is the principal formula?

    If you already know the Interest amount and want to calculate the Principal of Loan/ Deposit you can rearrange the interest formula SI = PRT to calculate the principal amount. The formula for calculating Principal amount would be P = I / where Interest is Interest Amount, R is Rate of Interest and T is Time Period.

    The Factors Affecting The Interest Earned And The Maturity Amount Are

    Math in Daily Life : How to Calculate Bank CD Interest
    • Principal amount – The interest earned is directly proportional to the principal amount. Higher the money deposited, higher the interest.
    • Rate of interest – Higher the rate of interest, higher the interest earned.
    • Deposit type – There are two kinds of fixed deposits. Cumulative deposits allow interests to be paid at maturity and Fixed Deposits allow interests to be paid monthly or quarterly, as per your choice. Cumulative deposits enable you to earn more as the interest income is reinvested. If you choose to take monthly interest the rate of interest would be discounted at the same rate and hence, the interest quantum earned is slightly less than quarterly pay- out. If you choose quarterly interest pay out option, the formula to arrive at interest quantum I is PxTxR/ where P is principal invested, T is term in days, R is rate of interest .

    Why Do Interest Rates Change

    There are a number of things the RBA will take into account when deciding whether to change the cash rate. Chief among them are domestic conditions, such as employment and inflation, though global financial conditions are also important.

    If the economy is booming and high demand is pushing up prices, the RBA might increase the cash rate to make sure inflation doesnât spiral out of control. And if the economy is weak and demand is low, the RBA might decrease the cash rate to encourage spending, borrowing and investment.
