Interest Rate (R): The rate at which interest is given.

Period (N): Number of periodic durations of the deposit or loan.

Compound Interest: Compound Interest extends to the added interests also. Banks mainly deal with compound interest.

Simple Interest: Simple interest works on the Principal Balance only. Banks may offer simple interest in special circumstances.

Compound Frequency (T): In the case of compound interest, interests are usually compounded daily, monthly, quarterly, semi-annually, and annually. Then the number of Compounding Times will be 365, 12, 4, 2, and 1 respectively.


Simple Interest Calculation in Excel

We can easily calculate Simple Interest using the following formula:

Simple Interest = Principal Amount Rate of Interest Time Periods

Follow the steps below to apply this formula.

Steps

  • Assume we have the following dataset.

  • Now, to calculate the final balance with interest added, apply the following formula in cell C10:
=C4+C9
  • You will see the accumulated balance as shown below.

  • At the end of each year, your account balance will be as follows.


Compound Interest Calculation in Excel

We can calculate compound interest using the formulas given below.

  • Compounded Amount (A) = P ✕ (1 +  I / T)  ✕ N ✕ T
  • Compound Interest = (A – P)

Follow the steps below to apply those formulas.

Steps

  • At first, apply the following formula in cell C12:
=C4*(1+C5/C7)^(C6*C7)

  • After that, enter the following formula in cell C13 to get the compound interest.
=C12-C4

EMI Calculation Using the PMT Function in Excel

Equated Monthly Installments or EMI is a very popular phenomenon nowadays. It is a fixed monthly payment by the borrower to repay a loan. You must learn how to calculate EMI to optimize your lending or borrowing options.

Assume, you want to buy a car for $35,000 and complete the payment in 12 EMIs at 5% yearly interest rate.

Follow the steps below to calculate the EMI.

Steps

  • At first, apply the following formula in cell C8:
=(((C4*C5/12)*(1+C5/12)^C6))/(((1+(C5/12))^C6)-1)

EMI calculation excel sheet made using formula

  • You can easily understand the above formula by observing and comparing the following formula.
=(((P*R/12)*(1+R/12))^N]/(((1+R/12)^N)-1)

Fortunately, excel also has an inbuilt function called the PMT function to calculate EMI.

How does the formula work?

The PMT function has the following arguments:

=PMT(rate,nper,pv,[fv],[type])

The arguments signify the followings:

  • Rate = Rate of interest applied on the borrowing.
  • NPER = Number of monthly installments per loan term which is N in this case.
  • PV = Present value or Principal amount (P)
  • FV = Future value after last payment which is 0 in this case
  • Type = 1 or 0. The payment due at the beginning of the month indicates 1 and 0 if it is at the end of the month.

Now, let’s check out this formula.

  • First, enter the following formula instead in cell C8:
=PMT(C5/12,C6,C4,,0)

  • Your monthly installments will be as follows.
