What is the meaning of compound interest?
In simple terms, compound interest can be defined as interest you earn on interest. With a savings account that earns compound interest, you earn interest on the principal (the initial amount deposited) plus on the interest that accumulates over time.
Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one. The total initial principal or amount of the loan is then subtracted from the resulting value. Katie Kerpel {Copyright} Investopedia, 2019.
Compound interest is when you earn interest on the money you've saved and on the interest you earn along the way.
Compound interest is what happens when the interest you earn on savings begins to earn interest on itself. As interest grows, it begins accumulating more rapidly and builds at an exponential pace. The potential effect on your savings can be dramatic.
Compound interest makes your money grow faster because interest is calculated on the accumulated interest over time as well as on your original principal. Compounding can create a snowball effect, as the original investments plus the income earned from those investments grow together.
Hence, if a two-year savings account containing $1,000 pays a 6% interest rate compounded daily, it will grow to $1,127.49 at the end of two years.
Rate of interest = 12% p.a. ∴ The compound interest is Rs. 10123.20.
Reinvesting your earnings from stocks, bonds, exchange-traded funds, mutual funds and real estate investment trusts can be a great way to earn compound interest on your money. For short-term needs, you may also consider high-yield savings accounts, money market accounts and certificates of deposit.
- Pay your balance in full. Credit cards often have a grace period, and your purchases won't accrue interest if you pay your statement balance in full each month.
- Use an introductory 0% APR offer. ...
- Transfer a balance.
The formula of monthly compound interest is: CI = P(1 + (r/12) )12t - P where, P is the principal amount, r is the interest rate in decimal form, and t is the time.
Can you lose on compound interest?
If you want to earn more, you could put your money into riskier investments like dividend stocks, mutual funds, and REITs. If the investment does well over time, you earn more yearly with compound interest. However, you also have the risk of losing money.
When you invest, your account earns compound interest. This means, not only will you earn money on the principal amount in your account, but you will also earn interest on the accrued interest you've already earned.
Compound interest is calculated by multiplying the initial loan amount, or principal, by one plus the annual interest rate raised to the number of compound periods minus one. This will leave you with the total sum of the loan, including compound interest.
For example, a $10,000 investment that returns 8% every year, is worth $10,800 ($10,000 principal x . 08 interest = $10,800) after the first year. It grows to $11,664 ($10,800 principal x . 08 interest = $11,664) at the end of the second year.
It can lead to significant financial burden
Compound interest on borrowings or on debt can be very dangerous. When left unchecked, your debt can quickly spiral out of control, leaving you in financial ruin.
Examples of Compound Interest
If, for instance, you made a $1,000 investment and earned $50 in interest at the close of the earning period, your principal is now $1,050. The interest rate is applied to $1,050 and not the $1,000 you invested when the interest calculation is made.
| Discount Rate | Present Value | Future Value |
|---|---|---|
| 5% | $1,000 | $2,653.30 |
| 6% | $1,000 | $3,207.14 |
| 7% | $1,000 | $3,869.68 |
| 8% | $1,000 | $4,660.96 |
As you will see, the future value of $5,000 over 20 years can range from $7,429.74 to $950,248.19. This is the most commonly used FV formula which calculates the compound interest on the new balance at the end of the period.
Interest on investment rate: 6% p.a. It would take 12 yearsto double an investment of $2,000.
Principle = Rs. 5000, rate = 5%, time = 2 years. Hence, the answer is Rs. 512.50.
What is the compound interest on 5000 for 3 years?
5000, R is rate of interest i.e. 5% and N is time period i.e. 3 years. Now, to find compound interest, we will subtract principal amount from the amount i.e. $ I=A-P=5788.125-5000=Rs. 788.125 $ .
A borrower who pays 12% interest on their credit card (or any other form of loan that is charging compound interest) will double the amount they owe in six years. The rule can also be used to find the amount of time it takes for money's value to halve due to inflation.
