Key Concepts (Simple Interest)

  • Interest: money paid for borrowing or earned for investing.
  • Simple interest: interest not compounded (not added back to principal); calculated period by period.
  • Capital/principal stays constant throughout the investment or loan.

Variables / Notation

  • t = time (number of periods)
  • c = initial capital/principal (amount invested/borrowed)
  • i = interest rate (percentage per time unit)
  • Final value (Vf/amount) = capital + interest

Formulas Provided

  • Interest: [ I = c \times i \times t ]

  • Final value: [ Vf = c + I ]

  • Equivalent form: [ Vf = c + (c \times i \times t) ]

Examples and Computed Results

1) Example 1

  • Principal (c): 1,000 pesos
  • Monthly interest rate (i): 10% = 0.10
  • Time (t): 5 months
  • Interest each month: (1{,}000 \times 0.10 = 100) pesos

Final value after 5 months:

  • Total interest: (5 \times 100 = 500) pesos
  • Vf: (1{,}000 + 500 = 1{,}500) pesos

Accumulated amounts by month:

  • Month 1: 1,100
  • Month 2: 1,200
  • Month 3: 1,300
  • Month 4: 1,400
  • Month 5: 1,500

2) Exercise 1 (worked)

  • Principal (c): 900,000 pesos
  • Rate: 5% monthly = 0.05
  • Time: 7 months
  • Interest: (900{,}000 \times 0.05 \times 7 = 315{,}000) pesos

3) Exercise 2 (worked)

  • Principal (c): 400,000 pesos
  • Rate: 2.5% monthly = 0.025
  • Time: 1 year = 12 months
  • Interest: (400{,}000 \times 0.025 \times 12 = 120{,}000) pesos

Note: The subtitle is said to contain a likely inconsistency later (“10 months”), but the calculation uses 12 months.

Method / Step-by-Step Framework (Implied)

  1. Identify:
    • Principal/capital (c)
    • Interest rate (i) and convert % → decimal
    • Time (t) and ensure the time unit of the rate matches the time unit of (t)
  2. Compute interest:
    • (I = c \times i \times t)
  3. Compute final value if needed:
    • (Vf = c + I)

Emphasis: principal remains constant (no compounding).

Notable Instruments / Assets Mentioned

  • No market tickers/ETFs/crypto/bonds/commodities mentioned.
  • Currency example uses bank/investment principal in pesos.

Disclosures / Cautions

  • No explicit “financial advice” disclaimer included in the subtitles.
