The Formula for Calculating Future Value with Compound Interest

The Formula for Calculating Future Value with Compound Interest
Adriano Casanova

If your initial investment is $5,000 with a 0.5% daily interest rate, your interest after the first day will be $25. If you choose an 80% daily reinvestment rate, $20 will be added to your investment balance,
giving you a total of $5020 at the end of day one. The more frequently that interest is calculated and credited, the quicker your account grows. The interest earned from daily
compounding will therefore be higher than monthly, quarterly or yearly compounding because of the extra frequency of compounds. Daily-calculated compound daily interest is a variation of compound interest. This indicates that interest is calculated and applied daily to the investment account.

  • Just enter your beginning balance, the regular deposit amount at any specified interval, the interest rate, compounding interval, and the number of years you expect to allow your investment to grow.
  • The method is
    simple – just divide the number 72 by your annual interest rate.
  • The resultant amount will be the future value of the amount invested, compounded semi-annually.
  • The Rule of 72 is a shortcut to determine how long it will take for a specific amount of money to double given a fixed return rate that compounds annually.
  • You may also be interested in the credit card payoff calculator, which allows you to estimate how long it will take until you are completely debt-free.

In finance, the interest rate is defined as the amount charged by a lender to a borrower for the use of an asset. So, for the borrower, the interest rate is the cost of the debt, while for the lender, it is the rate of return. Let’s cover some frequently asked questions about our compound interest calculator. As we compare the compound interest line in our graph to those for standard interest and no interest at all, it’s clear to see how compound interest
boosts the investment value over time.

You may, for example, want to include regular deposits whilst also withdrawing a percentage for taxation reporting purposes. Or,
you may be considering retirement and wondering how long your money might last with regular withdrawals. You can include regular withdrawals within your compound interest calculation as either a monetary withdrawal or as a percentage of interest/earnings.

Note that when doing calculations, you must be very careful with your rounding. For standard calculations, six digits after the decimal point should be enough. The value of your investment after 10 years will be $16,288.95.

This example shows monthly compounding (12 compounds per year) with a 5% interest rate. If you want to find out how long it would take for something to increase by n%, you can use our rule of 72 calculator. This tool enables you to check how much time you need to double your investment even quicker than the compound interest rate calculator. Use the tables below to copy and paste compound interest formulas you need to make these calculations in a spreadsheet such as Microsoft Excel, Google Sheets and Apple Numbers. Within our compound interest calculator results section, you will see either a RoR or TWR figure appear for your calculation. For the remainder of the article, we’ll look at how compound interest provides positive benefits for savings and investments.

The daily interest rate in this instance would be 0.0137% (5%/365). Compound interest is the interest earned on both the initial investment and the interest accrued over time. Daily, monthly, quarterly, or annual calculations of compound interest are possible, depending on the terms of the investment. The frequency of compounding affects the amount of interest earned. To compare bank offers that have different compounding periods, we need to calculate the Annual Percentage Yield, also called Effective Annual Rate (EAR). This value tells us how much profit we will earn within a year.

What is the effective annual interest rate?

If you’re
receiving 6% then your money will double in about 12 years. If you include regular deposits or withdrawals in your calculation, we switch to provide you with a Time-Weighted Rate of Return (TWR). Once you have these figures, you can quickly understand how much you will earn from an investment that uses the power of compounding interest.

For this reason, lenders often like to present interest rates compounded monthly instead of annually. For example, a 6% mortgage interest rate amounts to a monthly 0.5% interest rate. However, after compounding monthly, interest totals 6.17% compounded annually. In reality, investment returns will vary year to year and even day to day.

By understanding how it operates and the factors that go into its calculation, investors can make informed investment decisions and potentially realize substantial financial gains.

As an example, you may wish to only reinvest 80% of the daily interest you’re receiving
back into the investment and withdraw the other 20% in cash. This is often the case with trading where margin is used (you are borrowing money to trade). Additionally, investors should be aware that not all investments offer daily interest that is compounded.

Total Balance

This loop will continue allowing the investment to grow substantially without any additional investment capital. With time, this cycle has potential for a substantial growth of the original investment. Since the interest-on-interest effect can generate positive returns based on the initial principal amount, it has sometimes been referred to as the snowball effect of compound interest.

Compound: What it Means, Calculation, Example

This concept of adding a carrying charge makes a deposit or loan grow at a faster rate. The interest rate is commonly expressed as a percentage of the principal amount (outstanding loan or value of deposit). Usually, it is presented on an annual basis, which is known as the annual percentage yield (APY) or effective annual rate (EAR).
