Use the equation $=$0*(1 + r)xn
where $ is the amount of money, $0 is the initial amount of money, r is the rate, x is the number of times per year the interest is compounded, and n is the number of years the interest is compounded. We are solving for n. To do this we need to use logs.
log(1 + r)($/$0)/x = n
log1.08(5006/1000)/12 = n = 1.744 years.

With the same rate of interest, monthly compounding is more than 3 times as large.The ratio of the logarithms of capital+interest is 3.
Simple interest (compounded once) Initial amount(1+interest rate) Compound Interest Initial amount(1+interest rate/number of times compounding)^number of times compounding per yr
An effective annual interest rate considers compounding. When the principle is compounded multiple times each year the interest rate increased to be more than the stated interest rate. The increased interest rate is the effective annual interest rate.
The future value of a $1 deposit after 24 years depends on the interest rate and compounding frequency. For example, if the deposit earns an annual interest rate of 5% compounded annually, it would grow to approximately $3.20. At a 3% annual interest rate, it would amount to around $1.93. To calculate the exact amount, you can use the formula for compound interest: ( A = P(1 + r/n)^{nt} ), where ( P ) is the principal amount, ( r ) is the annual interest rate, ( n ) is the number of times interest is compounded per year, and ( t ) is the number of years.
To calculate the future value of an investment of $300 at a 4% annual interest rate compounded monthly, you can use the formula ( A = P \left(1 + \frac{r}{n}\right)^{nt} ), where ( P ) is the principal amount ($300), ( r ) is the annual interest rate (0.04), ( n ) is the number of times interest is compounded per year (12), and ( t ) is the number of years. For example, after 1 year, the amount would be approximately ( A = 300 \left(1 + \frac{0.04}{12}\right)^{12 \times 1} ), which equals about $312.16. The total will increase with the duration of the investment.
To calculate the future value of an investment with compound interest, you can use the formula: ( A = P(1 + \frac{r}{n})^{nt} ), where ( A ) is the amount of money accumulated after n years, ( P ) is the principal amount (initial investment), ( r ) is the annual interest rate (decimal), ( n ) is the number of times interest is compounded per year, and ( t ) is the number of years. For $500 invested at a 6% annual interest rate compounded monthly for 4 years: ( A = 500(1 + \frac{0.06}{12})^{12 \times 4} ) Calculating this gives approximately $634.96.
To calculate the future value of an investment compounded monthly, you can use the formula: ( A = P(1 + \frac{r}{n})^{nt} ), where ( A ) is the amount of money accumulated after n years, including interest; ( P ) is the principal amount ($200); ( r ) is the annual interest rate (0.05); ( n ) is the number of times that interest is compounded per year (12); and ( t ) is the number of years the money is invested (9). Plugging in the numbers, the future value will be approximately $319.84 after 9 years.
Yes: a year is not 50 weeks.
No. If the account is earning interest the current amount should be greater than the initial deposit.
Compound Interest FormulaP = principal amount (the initial amount you borrow or deposit)r = annual rate of interest (as a decimal)t = number of years the amount is deposited or borrowed for.A = amount of money accumulated after n years, including interest.n = number of times the interest is compounded per yearExample:An amount of $1,500.00 is deposited in a bank paying an annual interest rate of 4.3%, compounded quarterly. What is the balance after 6 years?Solution:Using the compound interest formula, we have thatP = 1500, r = 4.3/100 = 0.043, n = 4, t = 6. Therefore, So, the balance after 6 years is approximately $1,938.84.
