2017 Guide: Finding the Top 5 Best Annual and Monthly Compound Interest Calculators

If you are looking to open a new savings account or loan account, understanding how the bank will use its interest rate is important. An interest rate can be calculated with two methods: simple and compound.

Simple interest is calculated only on the principal amount, whereas compound interest continues to build on the principal plus interest. Compound interest can be calculated daily, weekly, monthly, or annually.

Of course, if you are using any financial product where compound interest is used, like a savings account or loan, you will need to have a basic understanding of interest compounded monthly or annually. These are two of the most common time frames banks use to compound interest.

Fortunately, you do not have to memorize the monthly compound interest formula or annual compound interest formula. The compounded monthly formula and annual formula are handy to know, but if you need a fast calculation when choosing between accounts to open, a compounded monthly interest calculator or annual calculator can help.

A monthly or annual compound interest calculator will tell you how much money you will pay on a loan or how much you will have in savings after a specific time period. The compounded annually or compounded monthly interest formula built into the calculator will use your inputted principal amount, contributions, and other factors to provide the end result.

Our list of 5 best interest compounded monthly or annually calculators have all been tested for accurate results with the compounded monthly interest formula and annual formula. They also ask for the most important information necessary to create the most accurate result.

Why Is It Important to Understand the Annual and Monthly Compound Interest Formula?

Even if you use a calculator that computes the monthly compound interest formula or annual compound interest formula, understanding how each formula works is important. This not only helps you check the accuracy of the compound interest monthly calculator or annual calculator, but it also helps you understand how interest is calculated.

You can use the same annual compound interest formula to compute a compounded monthly formula. The compound interest formula is A = P (1 + r/n)nt, where:

  • A is the future value of the amount, or the end result after the period of savings or the loan
  • P is the principal investment or loan amount
  • r is the annual interest rate as a decimal
  • n is the number of times the interest is compounded per year, which is how this formula can be both a compounded monthly interest formula or annual formula
  • t is the length of time, in years, that you save or borrow

The compound interest with monthly contributions formula is a bit more complex, so we suggest using a compound interest monthly calculator or compounded annually calculator to input your expected contributions.

Which One Is Better: Compounded Monthly Formula or Annual Compound Interest Formula?

Should you choose to save money in an account that uses the compounded monthly formula or annual formula? Which formula is better for a loan?

A good rule of thumb is to remember that interest compounded monthly adds more to your principal investment or loan. When you are saving money, a compounded monthly calculator will show you that this method will provide you with a higher final value than annually compounded interest.

However, when you are borrowing money, annually compounded interest can save you money. Interest will only be compounded once per year on the amount you still owe, rather than every month. If you are still unsure of what type of interest is better for you, utilize one of these compounded monthly interest calculators or annual calculators to find the differences in final value.
