About Effective Interest Rate Calculator The Effective Interest Rate Calculator is used to calculate the effective annual interest rate based on the nominal annual interest rate and the number of compounding periods per year. Leave blank if the compounding is continuous.The doubling time formula with continuous compounding is the natural log of 2 divided by the rate of return.

The formula for doubling time with continuous compounding is used to calculate the length of time it takes doubles one's money in an account or investment that has continuous compounding. It is important to note that this formula will return a time to double based on the term of the rate. For example, if the monthly rate is used, the answer to the formula will return the number of months it takes to double.

If the annual rate is used, the answer will then reflect the number of years to double. The individual could either calculate the number of years or calculate the number of months to double his investment by using the annual rate or the monthly rate. The doubling time with continuous compounding formula can be found by first looking at the continuous compounding formula individually. FV is the future value and PV is the present value. To double one's money would be to have the future value equal to twice the amount of the present value.

Considering this, we can substitute 2 for FV and 1 for PV in the formula above. This would show. The denominator of the formula above becomes simply rwhich is the formula shown at the top of the page. This site was designed for educational purposes.

These formulas can be spun accordingly to solve for principal and time. If you wonder how to calculate compound interest, these formulas provide the answer. The compounding frequency, which is the time period at which interest is added to the principal, can have a slight positive effect on the effective interest rate versus the nominal annual interest rate.

Using shorter compounding periods in our compound interest calculator will easily show you how big that effect is. You get the best effective rate when you have daily compounding also called continuous compounding and slightly worse with monthly or yearly compounding.

There will be no contributions monthly or yearly deposits to keep the calculation simpler. During the first year the math is just that of simple interest. The rate of capital growth is simply the interest rate. The table below shows the result of applying these equations to years 3, 4, and 5, and the final result:. This might not seem like much, but if the rate of return is higher or the period over which compounding occurs is longer, the compounding effect can be dramatic.

The above example has already shown the difference between simple versus compound interest.The following calculator allows you to quickly determine the answer to these sorts of questions.

To calculate your forecasted earnings on an investment, enter your initial investment, the amount you plan to add periodically, the anticipated interest rate, the compounding interval, and how long you anticipate holding the investment.

We also provide a calculator that lets you enter a savings goal and then solve for the contribution needed to reach that goal. Is your bank offering competitive rates which beat inflation and taxes? The following table lists currently available rates for savings accounts, money market accounts and CDs.

We are constantly shown numbers which are stripped of context. This calculator aims to strip things down to the essence, showing how the compounding impacts of interest add up when compounded at different intervals. He who understands it, earns it Using the above formula, you can calculate the future value of any unit of currency. Then multiply the result by your initial investment amount to get your total future savings. If you want to calculate your returns, you would then take that multiplied initial investment and subtract the initial investment to get the absolute nominal return.

However that view misses the compounding aspect of interest, which grows the money much faster. A person who gets a payday loan and rolls it over a few times can pay usurious interest rates quickly running into the hundreds or thousands of percent after accounting for various fees and penalties.

Simple interest refers to interest earned only on the principal, usually denoted as a fixed percentage of the principal. Determining a single interest payment is as simple as multiplying the interest rate with the principal. Simple interest is seldom ever used in real world applications of interest. On the other hand, compound interest is interest earned on both the principal and on the accumulated interest.

Because interest is also earned on interest, earnings compound over time like an exponentially-growing, avalanching snowball.

Compound interest is widely used for interest calculations on many things including mortgages, auto loans, banking, and much more. In order to determine whether interest is compounded or not in the U. Another way to determine whether interest is simple or compounded is to look at the repayment schedule for the loan.

Tax —If any taxation is to be applied, the rate and timing of taxation will affect the magnitude of compounding interest.

The less that taxation is involved, the greater the magnitude of compounding because of fewer reductions in the balance of the investment. Interest can be compounded on any given frequency schedule, and the calculator allows the conversion between compounding frequencies of daily, bi-weekly, semi-monthly, monthly, quarterly, semi-annually, annually, and continuously infinitely many number of periods.

The interest rates of savings accounts and Certificate of Deposits CD tend to be compounded annually. Home mortgage loans, home equity loans, and credit card accounts tend to be compounded monthly. There is evidence from ancient texts that compound interest was first used years ago by the Babylonians and Sumerians, two of the earliest civilizations in human history. However, their application of compound interest was quite different from what is widely used today.

Historically, simple interest was mostly considered legal. However, certain societies didn't grant the same legality to compound interest, labeling it as usury. For example, it was severely condemned by Roman law, and both Christian and Islamic texts have described it as a sin.

Nevertheless, compound interest has been in use ever since.The continuous compounding formula is used to determine the interest earned on an account that is constantly compounded, essentially leading to an infinite amount of compounding periods. The effect of compounding is earning interest on an investment, or at times paying interest on a debt, that is reinvested to earn additional monies that would not have been gained based on the principal balance alone.

By earning interest on prior interest, one can earn at an exponential rate. The continuous compounding formula takes this effect of compounding to the furthest limit. Instead of compounding interest on an monthly, quarterly, or annual basis, continuous compounding will effectively reinvest gains perpetually. To calculate the ending balance after 2 years with continuous compounding, the equation would be. Although the concept of infinite seems that it would return a very large amount, the effect of each compound becomes smaller each time.

The continuous compounding formula can be found by first looking at the compound interest formula. When nor the number of times compounded, is infinite the formula can be rewritten as. The limit section in the middle of the formula can be shown as e rwhich leads to the formula at the top of the page. This site was designed for educational purposes.
