You can put this solution on YOUR website!
you did not specify the type of loan.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "is it flat rate or is it compound rate from the remaining balance?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if flat rate, the formula would be:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i = p * r * n\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i is the interest
\n" ); document.write( "p is the principal
\n" ); document.write( "r is the interest rate per time period
\n" ); document.write( "n is the number of time periods\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in your problem, the formula becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "i = 12000 * .12 * 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this results in i = 5760.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that would be the total interest that would be paid after 4 years.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the total amount that would have to be repaid is the principal plus the interest.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that would be 12000 + 5760 = 17760.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "he would more then likely pay this in equal installments of 17760 / 4 = 4440 per year.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "if the loan type is compound interest on the remaining balance, then a different calculation is required.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "while there are formulas to allow you to calculate this manually, it is best solved by using a financial calculator.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "one such calculator can be found at https://arachnoid.com/finance/\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you would need to find the annual payments required before determining what the total interest is to be repaid.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "here are what the inputs look like for that calculation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"$$$\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "here is what the output looks like.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"$$$\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the total interest paid would be 4 * 3950.81 minus 12000 = 3803.52.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "that's the payment amount times the number of payments minus the initial loan amount.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in the flat rate loan, the interest is calculated off the original amount of the loan.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in the remaining balance loan, the interest is calculated from the remaining balance at the end of each time period.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "for the same interest rate, you will pay less overall interest with the remaining balance type loan.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "not knowing what type of loan you are talking about, i calculated for what type i know they usually are.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "to summarize.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "with flat rate type loan:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a. Calculate the interest that Larry must pay.
\n" ); document.write( "interest = 5760.
\n" ); document.write( "b. What is the total amount that Larry must repay?
\n" ); document.write( "total amount to be be repaid is 17760.
\n" ); document.write( "c. If Larry repays the loan in equal annual installments, calculate the amount of each repayment.
\n" ); document.write( "amount of each payment would be 4440.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "with compound interest remaining balance type loan:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a. Calculate the interest that Larry must pay.
\n" ); document.write( "interest = 3803.25.
\n" ); document.write( "b. What is the total amount that Larry must repay?
\n" ); document.write( "total amount to be repaid is 15803.25.
\n" ); document.write( "c. If Larry repays the loan in equal annual instalments, calculate the amount of each repayment.
\n" ); document.write( "amount of each payment would be 3950.81.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "note that in the compound interest remaining balance type loan, you need to calculate the payment required before you can calculate the total interest to be paid.\r
