Study Notes

Simple Interest and Bank Discount

Distinction exists between lenders (creditors) who provide funds and borrowers (debtors) who receive funds.
Simple interest is calculated only once based on the principal amount, rate, and time duration of the loan.
Formula for simple interest: Interest = Principal x Rate x Time.
Example: Borrowing P280,000 at 9% for one year results in P25,200 interest.
Total maturity value combines principal and interest: Maturity Value = Principal + Interest; for example, P305,200.

Concept of Time

The time factor (T) in interest calculations represents the duration between loan issuance and maturity.
Time can be expressed in exact years or as fractions. For example, 1.5 years represents 1 year and 6 months.
Months can be converted to fractional years, such as 9 months as 0.75 years or 15 months as 1.25 years.
When time is specified in months, maturity date aligns with the loan date.

Interest Calculation Methods

Calculation of interest can utilize actual or approximate time measures, with two methods for interest definitions:
- Exact interest method (365 days).
- Ordinary interest method (360 days).
For short durations, interest varies significantly between methods; ordinary interest may yield higher results.

Practical Applications

Understanding maturity dates and their implications is crucial for both lenders and borrowers.
The four combinations of calculating time include actual and approximate methods using both exact and ordinary interest calculations.
Illustrative calculation example shows variations in interest based on the method applied.

Key Learning Concepts

Compounding is distinct from simple interest; simple interest is usually preferred for loans under one year.
Financial literacy around borrowing, repayment, and interest formulations is essential for managing loans effectively.
Familiarity with terms like bank discount, promissory note, and the implications of interest management are important for sound financial practices.
