How Interest Grows Your Investments
You want to earn interest when you deposit money – but have you ever wondered how it works?
Interest is a fee that is paid by a borrower to an investor, compensating the investor for the use of their funds. Interest rates are one way financial institutions encourage deposits – and they are also a way for them to make money from borrowers.
Interest is usually calculated based on the principal and it can be easily calculated using the Interest Calculator.
Variable Vs. Fixed Interest Rates
Variable interest rates – also known as floating interest rates – are not fixed, but are dependent on market performance. If the market is volatile, interest rates also change dramatically during the entire course of the term. If you do not expect to keep a loan for a long time, then a variable interest rate may be more desirable over a fixed interest rate. The downside to variable rates is that if the interest rate rises, you may not be able to meet your payment obligations.
Fixed interest rates, on the other hand, do not change over the course of the term. The advantage of a fixed interest rate is that it allows you to plan your spending easily – the rate is set in stone. The disadvantage is that if interest rates drop significantly, as a borrower you’ll still pay the higher, original rate.
Simple Vs. Compounded Interest
Simple interest rate is calculated by multiplying the principal by the interest rate by the number of payment periods over the life of the loan. Here’s the formula:
P = The loan amount.
I = The interest rate.
N = The duration of the loan using the number of periods.
Compound interest refers to charges that the borrower must pay not just on the principal amount borrowed, but also on any interest accumulated at that point in time.
This online interest calculator compounds on a monthly basis, helping you determine the affects of compounding on interest-earning investments.
Compare Interest Rates
Before you invest money, first compare and calculate the affects of various interest rates. Interest rates should play an important role in your decision-making process.
This interest calculator not only shows you the affects of simple monthly interest, but it also shows you the future value if interest is compounded every month. Choose an investment (such as a savings account or other financial product) with a high interest rate that compounds – you’ll be glad you did.
