Simple and compound interest calculation is the first step to wealth management. You can use simple and compound interest calculators to quickly calculate and compare the differences.

Simple and compound interest

I have introduced simple interest and compound interest in my book “The Rules of Super Growth Stocks Investing”. The difference between simple interest and compound interest is the first step in financial management.

Why develop simple and compound interest calculator?

For the average person, it is easy to calculate the interest rate for one or two years, but it is difficult to see it at a glance or through mental arithmetic for a long period of time. Most people will use Excel or Google, or to search for calculation formulas on the internet.

Like the annualized rate of return on investment (aka IRR), the calculation of simple interest and compound interest is really a fundamental work for wealth management. I decided to write an interest rate calculator, calculate the results of using simple interest and compound interest respectively.
