Study Notes
Simple Interest Calculations
- Simple interest formula: ( I = P \times r \times t ), where ( I ) is interest, ( P ) is principal, ( r ) is rate (as a decimal), and ( t ) is time in years.
- Interest earned from a 1 million pesos deposit at a 0.25% rate for 1 year:
- Calculation: ( I = 1,000,000 \times 0.0025 \times 1 = 2,500 ) pesos.
- Interest from borrowing 4,000 pesos at an 8% rate for 6 months:
- Calculation: ( I = 4,000 \times 0.08 \times 0.5 = 160 ) pesos.
- Balance after 18 months with a 15,000 pesos deposit at 4.2%:
- Calculation: ( I = 15,000 \times 0.042 \times 1.5 = 945 ); Total balance = 15,000 + 945 = 15,945 pesos.
- Duration of deposit for 1,800 pesos interest at 5% on a 20,000 pesos principal:
- Rearrangement of the formula gives ( t = \frac{I}{P \times r} ); hence ( t = \frac{1,800}{20,000 \times 0.05} = 1.8 ) years or 1 year and 9 months.
- Interest earned from a 2,000 pesos deposit at a 2% rate for 1 year:
- Calculation: ( I = 2,000 \times 0.02 \times 1 = 40 ) pesos.
- Interest on a 5,000 pesos loan at 6% for 3 months:
- Calculation: ( I = 5,000 \times 0.06 \times 0.25 = 75 ) pesos.
- Balance from a 10,000 pesos deposit at 3.5% for 2 years:
- Calculation: ( I = 10,000 \times 0.035 \times 2 = 700 ) pesos; Total balance = 10,700 pesos.
- Finding the annual interest rate from a 3,500 pesos deposit yielding 3,605 pesos after 1 year:
- Interest earned = 3,605 - 3,500 = 105 pesos; therefore, ( r = \frac{I}{P \times t} = \frac{105}{3,500 \times 1} = 0.03 ) or 3%.
Compound Interest Formulas and Calculations
- Present value formula in compound interest:
- This usually involves the formula ( PV = FV / (1 + r)^n ), where ( FV ) is future value, ( r ) is rate per period, and ( n ) is number of periods.
- To find how much an investment grows with specific rates and terms using compound interest calculations.
- 8,000 pesos growth to 10,200 pesos in 2 years compounded quarterly requires finding the effective interest rate.
Compounding and Accumulations
- Rate to turn 5,000 pesos into 8,400 pesos in 7 years compounded semi-annually can be calculated via rearranging the compound interest formula to find ( r ).
- Rate insight if 70,000 pesos turns into 11,100 pesos in 5 years with compounding effects.
- Duration it takes for accumulating investments with specific principal amounts at given interest rates across varying compounding frequencies.
Summary of Investments
- Repeated calculations involve varying principal amounts and interest rates to provide interest earnings or final balances after set durations.
- Relate understanding of simple vs. compound interest affecting long-term savings and loans: Simple interest is straightforward, but compound interest can massively impact the total return over time due to calculations based on accrued interest.
