Principal in Agency Relationships
- Express Authority: Where the agent has explicitly been given the authority to act on behalf of the principal.

Financial Principal
The principal in finance refers to the amount of money initially invested or loaned, separate from any interest or earnings. For example, in a loan of $10,000, the $10,000 is the principal, and any additional amount paid over time represents the interest.
Agency Principal
In an agency relationship, the principal is the person who authorizes an agent to act on their behalf. This could be in a business, legal, or financial context. For example, in real estate transactions, the homeowner (principal) hires a real estate agent (agent) to sell their property.
$$ I = P \times r \times t $$
Where:
- \( I \) = Interest
- \( P \) = Principal
- \( r \) = Rate of interest
- \( t \) = Time period
$$ A = P \left(1 + \frac{r}{n}\right)^{nt} $$
Where:
- \( A \) = Amount
- \( P \) = Principal
- \( r \) = Annual interest rate
- \( n \) = Number of times interest is compounded per year
- \( t \) = Number of years
