#1
What is simple interest?
Interest calculated only on the principal amount
ExplanationInterest calculated solely on the initial sum.
#2
What is compound interest?
Interest calculated on the principal plus any accumulated interest
ExplanationInterest computed on both the initial amount and any accrued interest.
#3
What does APR stand for in the context of interest rates?
Annual Percentage Rate
ExplanationIt stands for Annual Percentage Rate.
#4
What is the difference between simple interest and compound interest?
Simple interest is calculated on the principal amount only, while compound interest is calculated on the principal plus accumulated interest.
ExplanationSimple interest relies solely on the initial amount, whereas compound interest factors in accrued interest.
#5
Which of the following is NOT a factor in determining the interest earned through an investment?
Current market value
ExplanationMarket value doesn't affect interest earned.
#6
What is the formula for calculating the future value of an investment with simple interest?
A = P(1 + r)
ExplanationFuture value equals principal multiplied by one plus the rate.
#7
What is the formula for calculating the present value of a future amount with simple interest?
PV = FV / (1 + r)
ExplanationPresent value equals future value divided by one plus the rate.
#8
What is the formula to calculate simple interest when the interest rate is given annually?
SI = P * r
ExplanationSimple interest equals principal multiplied by rate.
#9
What does the term 'principal' represent in interest calculations?
The initial amount of money
ExplanationPrincipal signifies the starting sum in interest computations.
#10
How is simple interest calculated?
P * r * t / 100
ExplanationSimple interest equals principal multiplied by rate and time divided by 100.
#11
How is compound interest calculated annually?
P * (1 + r)^n
ExplanationAnnual compound interest equals principal multiplied by one plus rate raised to the number of periods.
#12
What is the formula to calculate the effective annual rate (EAR) given a nominal rate (r) and the number of compounding periods per year (n)?
EAR = (1 + r/n)^n
ExplanationEffective annual rate equals one plus nominal rate divided by the number of compounding periods, raised to the number of compounding periods.
#13
Which of the following represents continuous compounding?
A = Pe^rt
ExplanationThe formula representing continuous compounding.
#14
What is the formula to calculate the simple interest earned on an investment?
SI = P * r * t
ExplanationSimple interest equals principal multiplied by rate multiplied by time.
#15
In compound interest calculations, what does 'n' represent in the formula A = P(1 + r/n)^(nt)?
Number of compounding periods per year
Explanation'n' denotes the frequency of compounding in a year.
#16
Which of the following is NOT a factor influencing the interest earned on an investment?
Payment frequency
ExplanationPayment frequency doesn't impact interest earned.
#17
What is the continuous compounding formula for calculating the future value of an investment?
A = Pe^rt
ExplanationContinuous compounding future value formula.
#18
Which of the following is a characteristic of simple interest?
Interest is calculated on the principal amount only
ExplanationSimple interest solely considers the initial sum.
#19
In compound interest calculations, what does 't' represent in the formula A = P(1 + r/n)^(nt)?
Number of years
Explanation't' denotes the duration in years.
#20
What is the formula to calculate the future value of an investment with compound interest?
A = P(1 + r/n)^(nt)
ExplanationFuture value equals principal multiplied by one plus rate divided by the number of periods, raised to the number of periods times time.
#21
What is the difference between simple interest and compound interest over a long period?
Compound interest always yields higher returns
ExplanationCompound interest outperforms simple interest over extended durations.
#22
What is the present value formula for discounting cash flows?
PV = FV / (1 + r)^n
ExplanationPresent value equals future value divided by one plus the rate raised to the number of periods.
#23
Which of the following best defines the effective annual rate (EAR)?
The annual rate that accounts for compounding effects and reflects the true rate of interest
ExplanationEAR captures compounding effects, revealing the actual interest rate.
#24
What is the formula for calculating the annual percentage yield (APY) from the annual nominal interest rate?
APY = (1 + r/n)^n - 1
ExplanationAPY formula incorporates compounding periods to derive the effective yield.
#25
What is the formula to calculate the future value of an investment with continuous compounding?
A = Pe^rt
ExplanationFormula for computing future value under continuous compounding.
