Study Notes
- Simple interest is calculated only on the initial investment amount.
Key Variables in Simple Interest Calculations
- Principal (P): The initial investment or loan amount.
- Interest rate (i): The annual percentage earned or paid, expressed as a decimal.
- Time period (n): The number of years.
- Accumulated amount (A): The final amount after interest.
Simple Interest Formula
- ( A = P (1 + in) ) computes the accumulated amount using simple interest.
- ( A ) represents the accumulated amount.
- ( P ) represents the principal amount.
- ( i ) represents the interest rate as a decimal.
- ( n ) represents the number of years.
Compound Interest
- Compound interest includes interest earned on both the principal and accumulated interest.
- Compound interest benefits investments due to exponential growth, but increases loan debts faster than simple interest.
Compound Interest Formula
- ( A = P(1 + i)^n ) determines the accumulated amount with compound interest.
- ( A ) represents the accumulated amount.
- ( P ) represents the principal amount.
- ( i ) represents the interest rate as a decimal.
- ( n ) represents the number of years.
The Power of Compound Interest
- Compound interest boosts investment growth significantly more than simple interest over time.
- Interest earned on interest leads to exponential growth, making it advantageous for investments but potentially risky for loans.
Hire Purchase Agreements
- A hire purchase agreement is when products are paid for in installments, including simple interest on the remaining balance after a deposit.
- The principal amount is the cash price minus the deposit.
- Interest is charged on the remaining loan at a simple interest rate.
- Monthly payments are calculated by dividing the total loan amount by the number of months.
Inflation
- Inflation refers to the average annual increase in the price of goods and services.
- The compound interest formula is used to calculate inflation.
Inflation Formula
- ( A = P(1 + i)^n ) calculates future prices based on inflation.
- ( A ) represents the future price.
- ( P ) represents the current price.
- ( i ) represents the inflation rate as a decimal.
- ( n ) represents the number of years.
Population Growth
- Population growth is calculated using the compound interest formula.
Population Growth Formula
- ( A = P(1 + i)^n ) is used to determine future population size.
- ( A ) represents the future population.
- ( P ) represents the current population.
- ( i ) represents the population growth rate as a decimal.
- ( n ) represents the number of years.
Foreign Exchange Rates
- Exchange rates dictate the value of one country's currency in terms of another.
- These rates impact the cost of international goods and services.
- Currency values increase when there's higher investment in a country.
- Buying local products strengthens the local currency.
- Common currencies include the British pound (£), American dollar ($), and euro (€).
Currency Conversion Formula
- (\text{Amount in new currency} = \frac{\text{Amount in original currency}}{\text{Exchange rate}}) is used to convert currencies.
