Example Question - annual percentage yield
Here are examples of questions we've helped users solve.
Analyzing Bank Savings Account with Compound Interest
The image is quite blurry, but from what I can gather, it seems to discuss a bank savings account scenario with an annual percentage yield (APY) of approximately 0.3% with monthly deposits. However, the clarity of the image is insufficient to confidently interpret all the details, such as the exact amount deposited monthly and other potential pertinent information. To solve a problem like this, you would typically use the formula for compound interest, which includes the principal amount, the rate, and the frequency of compounding. However, an APY already factors in compound interest over the course of a year, making the calculation somewhat simpler. If we had the exact APY rate (let's assume it's r), the initial deposit (P), and the monthly deposit amount (D), then you could find the amount in the account after one year using the following approach: A = P(1 + r) + D[ ((1 + r)^(n+1) - (1 + r)) / r ] Where: - A is the amount of money accumulated after n periods, including interest. - P is the principal amount (the initial amount of money). - D is the monthly deposit. - r is the monthly interest rate (annual rate/12). - n is the number of times that interest is compounded per year. Without the precise monthly deposit amount, it is impossible to calculate the exact amount. If you could provide clearer details, I would be able to assist you further in calculating the accumulated amount after one year.
Calculating Future Value and APY of a Savings Account
The question in the image is asking to calculate the future value of a savings account with an annual percentage rate of 3.8% with interest compounded monthly after one year, given an initial deposit of $2,000. Additionally, it asks to calculate the annual percentage yield (APY) for the savings account. To solve the first part of the question, we use the future value formula for compound interest: \[ A = P \left(1 + \frac{r}{n}\right)^{nt} \] Where: - \( A \) is the amount of money accumulated after n years, including interest. - \( P \) is the principal amount (the initial amount of money). - \( r \) is the annual interest rate (decimal). - \( n \) is the number of times that interest is compounded per year. - \( t \) is the time the money is invested for, in years. Given: - \( P = \$2,000 \) - \( r = 3.8\% = 0.038 \) (as a decimal) - \( n = 12 \) (since the interest is compounded monthly) - \( t = 1 \) year \[ A = 2000 \left(1 + \frac{0.038}{12}\right)^{12 \times 1} \] \[ A = 2000 \left(1 + 0.0031667\right)^{12} \] \[ A = 2000 \left(1.0031667\right)^{12} \] \[ A ≈ 2000 \times 1.03884 \] \[ A ≈ 2077.68 \] Jace will have approximately $2077.68 in the account after one year. For the second part of the question, we calculate the annual percentage yield (APY) which takes into account the effect of compound interest. APY can be calculated using the formula: \[ APY = \left(1 + \frac{r}{n}\right)^n - 1 \] Using the same values for \( r \) and \( n \), we have: \[ APY = \left(1 + \frac{0.038}{12}\right)^{12} - 1 \] \[ APY = \left(1.0031667\right)^{12} - 1 \] \[ APY ≈ 1.03884 - 1 \] \[ APY ≈ 0.03884 \] \[ APY ≈ 3.88\% \] The annual percentage yield (APY) for the savings account is approximately 3.88%.
Calculating Future Value and Annual Percentage Yield of Savings Account
The image contains a question which says: "A bank features a savings account that has an annual percentage rate of 3.8% with interest compounded monthly. Jace deposits $2,000 into the account. a) How much money will Jace have in the account in 1 year? Round answer to the nearest penny. b) What is the annual percentage yield (APY) for the savings account? Round to the nearest hundredth of a percent." Let's solve part a) first. We are given that the annual interest rate is 3.8% and it is compounded monthly. To find the total amount in the account after one year, we will use the formula for compound interest: A = P(1 + r/n)^(nt) Where: A = the future value of the investment/loan, including interest P = the principal investment amount ($2,000 in this case) r = the annual interest rate (decimal) (3.8% or 0.038) n = the number of times that interest is compounded per year (12 for monthly) t = the time the money is invested or borrowed for, in years (1 year in this case) Plugging in the values: A = 2000(1 + 0.038/12)^(12*1) A = 2000(1 + 0.0031667)^(12) A = 2000(1.0031667)^(12) Now use a calculator to evaluate the expression: A ≈ 2000(1.0031667)^12 A ≈ 2000 * 1.038726 A ≈ 2077.45 So, after one year, Jace will have approximately $2077.45 in the account, rounding to the nearest penny. For part b), the annual percentage yield (APY) takes into account the effect of compound interest over the year. It is calculated by the formula: APY = (1 + r/n)^(n) - 1 Again, substitute the values: APY = (1 + 0.038/12)^(12) - 1 APY = (1 + 0.0031667)^(12) - 1 Now evaluate the expression using the calculator: APY ≈ (1.0031667)^12 - 1 APY ≈ 1.038726 - 1 APY ≈ 0.038726 To express this as a percentage, multiply by 100: APY ≈ 0.038726 * 100 APY ≈ 3.8726% Rounding to the nearest hundredth of a percent, we get an APY of approximately 3.87%.
Compound Interest Calculation with Monthly Compounding
To solve for the amount Jace will have in the account after one year with an annual percentage rate of 3.8% and monthly compounding interest, we use the formula for compound interest: A = P(1 + r/n)^(nt), where: - A is the amount of money accumulated after n years, including interest. - P is the principal amount (the initial amount of money). - r is the annual interest rate (decimal). - n is the number of times that interest is compounded per year. - t is the time the money is invested for, in years. Given: P = $2,000 r = 3.8% or 0.038 (as a decimal) n = 12 (since interest is compounded monthly) t = 1 year Plugging these into the formula gives us: A = 2000(1 + 0.038/12)^(12*1) A = 2000(1 + 0.0031667)^(12) A = 2000(1.0031667)^(12) Calculating this out, we get: A ≈ 2000(1.038565) A ≈ 2077.13 So, after rounding to the nearest penny, Jace will have approximately $2077.13 in the account after one year. The question also asks for the annual percentage yield (APY). The APY takes into account the effect of monthly compounding and is calculated using the formula: APY = (1 + r/n)^(n) - 1 Using the same values for r and n: APY = (1 + 0.038/12)^(12) - 1 APY = (1.0031667)^(12) - 1 APY ≈ 0.038818 or 3.8818% After converting this to a percentage and rounding to the nearest hundredth of a percent, the APY is approximately 3.88%.
