Why is interest an exponential function?

Interest is often modeled as an exponential function because it grows at a rate proportional to its current value. In compound interest, for example, the interest earned in each period is added to the principal, leading to interest being calculated on an increasingly larger amount over time. This results in a rapid increase where the growth accelerates, characteristic of exponential growth. As a result, the formula for compound interest, ( A = P(1 + r/n)^{nt} ), reflects this relationship, showing how the amount grows exponentially based on the interest rate and time.


What interest applies when interest for each year is based on the amount of the loan or investment?

When each interest calculation uses the initial amount, this is called Simple Interest. The other type is Compound Interest, which uses the current balance as the basis for interest calculation.


Is simple interest at 4.25 percent better than compound interest at 4.25 percent?

Simple interest is the interest you earn on your principal, IE the amount of your original investment. For example, you put 1000 dollars in a saving account paying 3% per annum. At the end of the year you will have earned 30 dollars on that one thousand dollars. If you leave the principal and interest in the account for another year you will earn another 30.00 on your original 1000 dollars plus .90 interest. on the first 30.00 dollars interest. This gives you a total of 1060.90 in your second year. In each succeeding year you will earn interest on your interest plus interest on your original principal which, if left alone will add up to a substantial some given the power of compound interest. One caveat, compound interest is a double edged sword. If you have a loan and fail to make your monthly payments on time, compound interest will gut you financially.


Why the amount of interest earned increases in each succeeding years?

because the financial thing doesnt always have to.


What is the concepts of compound interest?
