Definition
Principal:
Principal is the original sum of money that is borrowed in a loan or placed into an investment. Translated from Latin as “first in importance,” it serves as the cornerstone for calculating interest on loans and returns on investments. In the context of bonds, principal refers to the face value that will be returned to the bondholder at maturity. Without principal, our finance-loving hearts would be a little broken. 💔
Principal vs. Interest Comparison
| Feature | Principal | Interest |
|---|---|---|
| Definition | The initial sum of money borrowed or invested. | The cost of borrowing the principal, usually expressed as a percentage. |
| Calculation | Fixed amount, typically does not change over time. | Variable, can change based on interest rates or loan terms. |
| Example | $10,000 loan for a car purchase. | $1,500 interest on the loan over the year. |
| Purpose | The amount upon which interest is calculated. | Compensation for lending/kindness to the borrower. |
Examples
-
In Finance: If you take out a $200,000 mortgage, your principal is $200,000. The monthly payments you make will pay off this principal amount while also covering the interest.
-
In Investments: If you invest $5,000 in a bond, that $5,000 is your principal, which will generate interest over time until the bond matures.
Related Terms
-
Amortization: The gradual payoff of a debt involving equal payments, dividing the principal and interest over a set term.
-
Loan Term: The duration over which the borrowed principal is to be paid back with interest.
Formulas
Calculating Interest:
To find the interest accrued over a period on a given principal, you can use the following formulas depending on whether the interest is compounded or simple:
-
Simple Interest:
\[ \text{Interest} = \text{Principal} \times \text{Rate} \times \text{Time} \] -
Compound Interest:
\[ A = P(1 + \frac{r}{n})^{nt} \] Where:
\( A \) = the amount of money accumulated after n years, including interest.
\( P \) = the principal amount (initial investment).
\( r \) = annual interest rate (decimal).
\( n \) = number of times that interest is compounded per year.
\( t \) = the number of years the money is invested or borrowed.
