Wondering what a compound interest calculator is or how to use it? Read the following sections and get a clear idea about the same!
What Is a Compound Interest Calculator?
Compound Interest Calculator is an online tool that helps loan applicants or investors calculate the amount they are going to pay or receive throughout the term of the loan or investment tenure.
A compound interest calculator helps individuals to create a projection for compound growth on a savings account or investment for a period of time on the basis of ongoing interest rates.
As individuals are aware of the compound interest calculator, we must focus on the calculation process.
What Is the Formula to Calculate Compound Interest?
There is a standardised compound interest formula. Individuals can use the following formula to compute compound interest easily,
Formula for Compound Interest Calculation:
A = P (1+r/n) ^nt
The variables in the formula are as follows,
A= Compound interest
P= Principal amount
R/r= Rate of interest
N/n= Number of times interest compounds in a year
T/t= Tenure/ number of years
Let’s decode the compound interest formula with an example,
Suppose an individual has invested ₹ 50,000 for 3 years at an annual interest rate of 10%. Therefore, in the first year, the accrued interest will be the following,
|
Pointers |
Value |
|
Principal |
₹ 50,000 |
|
Interest Rate |
10% |
|
Interest Earned (1st Year) |
₹ 50,000 x 10/100 = ₹ 5,000 |
|
Interest Earned (2nd Year- Interest will be calculated on the principal and accumulated interest of the 1st Year) Total Amount |
₹ 50,000 + ₹ 5,000= ₹ 55,000 (Principal+ interest of 1st year) Hence, interest earned on 1st year= ₹ 55,000 X 10/100 = ₹ 5,500 Total interest earned/accumulated in the 2nd year= ₹ 5,500+ ₹ 5,000 = ₹ 10,500 ₹ 50,000+ ₹ 10,500 = ₹ 60,500 |
|
Interest Earned (3rd Year- Interest will be calculated on the principal and accumulated interest of the 1st year and 2nd Year) Total Amount |
₹ 55,000 + ₹ 5,500 = ₹ 60,500 (Principal + interest of 2nd year) Hence, interest earned on 2nd year= ₹ 60,500 X 10/100 = ₹ 6,050 Total interest earned/accumulated in the 3nd year = ₹ 6,050 + ₹ 5,500 + ₹ 5,000 = ₹ 16,550 ₹ 60,500 + ₹ 6,050 = ₹ 66,550 |
The above calculation explains the difficulty of computing compound interest manually. To avoid such time-consuming calculations, one can undoubtedly rely on the formula used in a compound interest calculator. Read along!
