Q. Find the monthly payment for a 30 year loan of 100000 with an APR of 4%?
Convert APR to monthly rate: Convert the annual percentage rate (APR) to a monthly interest rate.The APR is given as 4%, which needs to be converted to a monthly rate since we are calculating a monthly payment. To do this, divide the APR by 12 (the number of months in a year).Monthly interest rate = APR / 12= 4% / 12= 0.04 / 12= 0.003333…
Convert rate to decimal: Convert the monthly interest rate to a decimal.To use the monthly interest rate in calculations, it needs to be in decimal form rather than a percentage.Monthly interest rate (in decimal) = 0.003333…
Determine number of payments: Determine the number of monthly payments over the life of the loan. Since the loan is for 30 years and payments are monthly, multiply the number of years by 12. Number of monthly payments = 30 years ×12 months/year =360 payments
Use payment formula: Use the formula for calculating the monthly payment on an installment loan.The formula is:Monthly payment = P×(((1+r)n−1)r(1+r)n)Where:P = principal amount (the initial amount of the loan)r = monthly interest rate (in decimal form)n = total number of payments
Plug values into formula: Plug the values into the formula to calculate the monthly payment.P=$100,000r=0.003333...n=360Monthly payment = $100,000×(0.003333...(1+0.003333...)360)/((1+0.003333...)360−1)
Calculate monthly payment: Calculate the monthly payment using the values provided.This step involves complex calculations that are typically done with a calculator or financial software. For the sake of this example, we will simplify the calculation process.Monthly payment ≈$100,000×(0.003333...×(1.003333...)360)/((1.003333...)360−1)
Perform final calculation: Perform the calculation to find the monthly payment. Using a calculator or financial software to handle the exponentiation and division, we find: Monthly payment ≈$477.42
