Q & A
What is the formula for calculating the future value of an annuity?
-The formula for future value of an annuity is FV = P / [(1 + i)^n - 1] / i, where FV is the future value, P is the regular payment, i is the interest rate per payment interval, and n is the total number of payments.
How do you convert a nominal interest rate to an equivalent interest rate for different compounding periods?
-To convert a nominal interest rate to an equivalent interest rate, use the formula i = r / m2 * m1, where r is the nominal rate, m1 is the number of payments per year, and m2 is the compounding frequency.
What does the variable 'm1' represent in the context of annuities?
-'m1' represents the payment interval, or the number of payments made in a year.
In the example given, what future value is being calculated for the first scenario?
-The future value being calculated in the first example is 50,000 pesos.
How many total payments are made in one year if payments are made monthly?
-If payments are made monthly, the total number of payments in one year is 12.
What is the equivalent monthly interest rate calculated for a nominal rate of 10% compounded quarterly?
-The equivalent monthly interest rate calculated for a nominal rate of 10% compounded quarterly is approximately 0.00826484.
What is the present value formula mentioned in the transcript?
-The present value formula is PV = P / [1 - (1 + i)^(-n)] / i, where PV is the present value, P is the regular payment, i is the interest rate per payment interval, and n is the total number of payments.
For the second example, how much does Alink need to deposit every three months to accumulate 500,000 pesos?
-Alink needs to deposit approximately 38,668.13 pesos every three months to accumulate 500,000 pesos in three years.
What is the total duration in years for the last example involving the insurance policy?
-The total duration for the last example involving the insurance policy is 10 years.
What is Nadine's monthly stipend based on the insurance policy's present value?
-Nadine's monthly stipend based on the insurance policy's present value is approximately 10,552.35 pesos.
