Compound interest is the accrual of interest on both the initial investment amount and on the interest earned over the previous years of the investment, ie. For example, after making a deposit, interest for the first year is accrued on the initial amount invested. In the second year, interest is accrued on the initial amount deposited and on the interest received in the previous year. In the third year, interest is accrued on the initial deposit and all the interest previously received. Assuming you’re asking how much interest you’ll earn on your savings account balance, the answer depends on the account’s interest rate and how much money is in the account.

- After one year, the bank gives you $1,000, so now you have $101,100.
- “Interest on interest,” or the power of compound interest, will make a sum grow faster than simple interest, which is calculated only on the principal amount.
That amount then accrues interest over each quarter until the end of the three years. It compounds according to the compound interest formula eleven times. Recall that the exponent on that formula is the number of compounding periods. Now let’s take a look at what happens at the end of the second quarter. Now, you deposit $135 again, but this time, this deposit will accrue interest using the compound interest formula ten times.
Compound Interest (FV) Calculator
Calculate the future value after 8 years present value of $35,000 with annual interest of 3% compounded monthly. An investor opting for a brokerage account’s dividend reinvestment plan (DRIP) is essentially using the power of compounding in their investments.

Apart from CI, this compound interest calculator helps you to calculate principal and rate of interest too.
More frequent compounding of interest is beneficial to the investor or creditor. The basic rule is that the higher the number of compounding periods, the greater the amount of compound interest. The following on-line calculator allows you to automatically determine the amount of monthly compounding interest owed on payments made after the payment due date.

It is precisely this figure which is the most important in calculating compound interest. The longer your investment account will be open, the more you can earn, because interest will compound every year.

Therefore, the fundamental characteristic of compound interest is that interest itself earns interest. This concept of adding a carrying charge makes a deposit or loan grow at a faster rate.
Simply divide the number 72 by the annual rate of return and the result of this is how many years it’ll take. Interest can be compounded on any given frequency schedule, from continuous to daily, monthly, quarterly to annually. When calculating compound interest, the number of compounding periods makes a significant difference for future earnings.
At the end of three years, simply add up each compound interest calculation to get your total future value. The power of compound interest lies in its ability to generate exponential growth over time by reinvesting earnings, leading to significant wealth accumulation and long-term financial advantages.

The longer the interest compounds for any investment, the greater the growth. 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.

However, their application of compound interest differed significantly from the methods used widely today. In their application, 20% of the principal amount was accumulated until the interest equaled the principal, and they would then add it to the principal.

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. One can use it for any investment as long as it involves a fixed rate with compound interest in a reasonable range. Simply divide the number 72 by the annual rate of return to determine how many years it will take to double.
