What is Compound Interest?

Compound interest is interest computed on a loan or deposit based on the original principal and the cumulative interest from previous periods. It's essentially "interest on money that was previously earned as interest." When opposed to simple interest, which is determined just on the principal amount, this permits your balance and interest to grow at a quicker rate.

The rate at which compound interest accumulates interest is proportional to the number of compounding periods; the larger the number of compounding periods, the higher the compound interest rate.

What is the formula for calculating compound interest?

To calculate compound interest, you should use the following formula:
A = P(1 + r/n)nt

In the formula:
A = Amount (principal + interest)
P = Principal amount
r = Annual nominal interest rate
n = number of compounding periods per unit of time
t = time in decimal years;

Example for Calculating Compound interest?

For example, if you invest Rs. 50,000 with an annual interest rate of 10% for 5 years, the returns for the first year will be 50,000 x 10/100 or Rs. 5,000. For the second year, the interest will be calculated on Rs. 50,000 + Rs. 5000 or Rs. 55,000. The interest will be Rs. 5550.

What is a compound interest calculator?

A compound interest calculator is a financial tool or online software application that helps individuals or businesses calculate the future value of an investment or loan when interest is compounded. Compound interest is the interest calculated on the initial principal as well as on any accumulated interest from previous periods. It can significantly affect the total amount you receive on an investment or the amount you owe on a loan.

Difference between simple and compound interest?

Simple Interest:

  • Calculations are based only on the initial principal amount.
  • Interest is calculated on the principal amount for the entire duration.
  • The interest remains constant throughout the investment or loan term.
  • Simple interest is typically used for short-term loans and simple savings accounts.

Compound Interest:

  • Calculations take into account both the initial principal amount and any previously earned interest.
  • Interest is calculated on the principal and any accrued interest, leading to exponential growth.
  • Interest can vary from period to period based on the compounding frequency (e.g., daily, monthly, annually).
  • Compound interest is used for most long-term investments, savings accounts, mortgages, and loans.

What is daily, monthly and yearly compounding?

Daily Compounding: Interest is calculated and added to the principal daily. This results in the most frequent compounding and potentially the highest returns or costs but can be administratively intensive.

Monthly Compounding: Interest is calculated and added to the principal once a month. It strikes a balance between frequent compounding and simplicity compared to daily compounding.

Yearly Compounding: Interest is calculated and added to the principal once a year. It's the least frequent compounding method, offering simplicity but potentially lower returns or costs compared to more frequent compounding intervals.


What is the excel formula for compound interest?

The basic formula to calculate compound Interest is: Interest = balance * interest rate / 100 This interest in above formula is then added to your balance to give the the total amount that you will get.


Which one is better, compounding quarterly or monthly?

For maximizing returns, monthly compounding is generally better. For simplicity and shorter-term goals, quarterly compounding can be a practical choice. The specific terms of your financial product and your financial goals will influence your decision.
