Reducing Rate of Interest Calculator with Flat in Excel

In this tutorial, we'll guide you through creating an Excel calculator that calculates reducing interest rates with flats rates in a few simple steps. You can use the Calculator to see what methods provide a higher financial return. So, let's dive right into the content, without any delay.

Flat Rate of Interest

The terms "reducing balance rate" and "flat rate interest" are unfamiliar to many people in the financial world. Being in the dark when handling your finances is not a good idea. Financial catastrophes can result from a lack of understanding of fundamental finance concepts. After completing this tutorial, these two phrases will be clear to you. Additionally, you will receive an Excel calculator with a flat and decreasing interest rate. First, let's look at the formula used to determine the flat interest rate.

An example will help you better comprehend this definition. Say you borrowed $200,000 at a six per cent annual percentage rate (APR). You have five years to repay the debt and must make an instalment payment each month. ($200,000 x 4 x 7%) / 48 will be your flat rate interest. You will pay your interest on this each time you make an instalment. Let's compute your principal repayments now.

The result of plugging in the numbers is = $200,000 / 48. Thus, your monthly payment total will be $4,166.67+ $1,166.67= $5,333.33.The following figure shows a summary of the computation done above utilizing my flat rate interest calculator. In addition, the Calculator displays the following data:

The entire amount paid: $256,000.00

$56,000.00 was paid in interest overall.

For the next five years, you will be paying an interest rate of 28% per cent. Do you realize that the rate is high?

Reducing Interest Rate

Banks and other financial organizations extensively use this strategy because it offers a more efficient way to manage loans. Using the loan information provided above, let's determine the decreasing interest rate.

  • A loan amount is $200,000.
  • Annual Percentage Rate(APR) 7%
  • A 4 years loan tenure is specified.
  • Monthly is the payment frequency.

The monthly rate must first be determined if the frequency of payments is monthly:

The next step is to use Excel's PMT function to determine the loan's monthly PMT:

This time, the numbers are as follows: rate = 0.005833333 nper = 48; [nper = total number of periods];-loan = -200,000; [loan equals negative since we want the PMT to be positive].

$4789.25 is the value that it returns.

Let's now talk about how the entire thing operates:

First Month:

You simply take out the loan at the beginning of the first month. That leaves a $200,000 balance. You are responsible for paying the financial institution $4789.25 (the PMT payment) at the end of the initial month. What percentage of this sum ($4789.25) is interest paid? The interest for the first month is $1166.67 ($200,000 x 0.005833333). Therefore, $1166.67 of the $4789.25 total is given as interest. You will be refunded $4789.25 less $1166.67 or $4789.25 as a portion of your principal. Your new principal, therefore, will be as follows at the end of the first month: $200,000 - $3,622.58= $196377.42.

Second Month:

At the beginning of the second month, $196,377.42 is your new principal. By the conclusion of the second month, you are giving the financial institution $4789.25, which is the PMT amount. To what extent is interest paid on this sum ($4789.25)? The interest for the second month is $196,377.42 x 0.005833 = $1145.5324. Therefore, the interest payment is $1145.5324 out of $4789.25. Your principal will be reduced by the remaining amount, which is $4789.25- $1145.53= $3643.72. Consequently, your new principal after the second month will be $196,377.42 - $3643.72= $192,733.7. That's how the entire procedure moves forward. You can see the entire procedure in the following pictures.

The graphic below illustrates how, at the most recent payment, we only paid $27.78 towards interest and used the remaining $4,761.47 to pay down our principal. We have 0.00 as our final balance. Therefore, that is our final payment to the bank.

See, using a loan with a decreasing interest rate is easy. The total interest we pay on this system is only 14.94% at the end of the day.

Instructions to follow while using this Calculator

This Calculator is incredibly simple to use. In this part, we'll walk you through the values you must enter and adjust.

To use this Calculator, enter the following values:

  • Amount of Loan
  • The rate of return on assets (APR)
  • Terms of the loan (years)
  • Date of Loan (mm/dd/yy)
  • Sort of payment. The list is drop-down. You'll be paid in two different ways. The period's beginning and conclusion. Pick one that works with your loan.
  • Frequency of payment: There is a drop-down list as well. Payment frequencies are selectable:
Interest Compound Days or Months No. of payments per year
Weekly 7Days 52
Bi-Weekly 14Days 26
Semi-Monthly 15Days 24
Monthly 1Month 12
Bi-Monthly 2Months 6
Quarterly 3Months 4
Semi-Annually 6Months 2
Yearly 12Months 1
  • Interest Compounding Frequency: Generally, the frequency of your payments will match the interest compounding frequency. Certain nations, like Canada, have semi-annual interest compounding with monthly payments. Your payment frequency will, therefore, always be equal to the interest compounding frequency, with very few exceptions.

No more variables need to be entered. The Calculator will do the remaining job.

Excel sheet featuring an EMI calculator with a prepayment option

Assume we have an Excel spreadsheet with the details of the EMI computation and a prepayment option. We will use Excel's PMT and IPMT finance algorithms to determine the EMI from our dataset with the prepayment option. PMT is a payment, while interest on payment is obtained using IPMT. With an Excel sheet with a prepayment option, we will use these financial tools to create the EMI calculator.

Steps:

  • See each of these fields and type in. Additionally, we created the template for 6 months. If necessary, you can add more.
