Installment Buying and Credit Cards
Simple Finance Charges The finance charge is the amount of the purchase in excess of the selling price. Barry wants to purchase a tv for $1540. Since he does not have the cash up front, he enter into an agreement to pay $55 a month for 36 months. Find the total cost and the finance charge for this purchase. 55*36=1980. therefore, the finance charge would be then =$440
Monthly Payments A light saber is for sale at a price of $1250, but it may be purchased on an installment plan by paying $300down, and then paying the balance plus 16% simple interest in 12 monthly payments. What would be the amount of each payment?
Using simple interest formula, I = 950*.16*1=$152. So = $1102 is the balance. Since there will be 12 payments, each one should be 1102/12=$91.83 The total cost of the light saber would be the price of $1250 plus the finance charge of 152, or $1402.
Ron Weasly buys a Nimbus 2000 for g450 (g-galleons, currency in the wizard world) and pays for it over two years with 11.5% simple interest. What is the monthly payment. I=450*.115*2= Total amount= = /24=23.06 So the monthly payment is g Except for the last month, the last month payment is g23.12
Credit card and Finance Charges The finance charge on a credit card is the simple interest on the average daily balance using a daily interest rate. The billing cycle is the number of days between credit card statements, and usually corresponds to the number of days in a specific month, which will be 28, 30 or 31 days.
How many days are in the billing cycle that runs from the June 15 through July 14? 30 days. If a credit card has a balance of $20 for 21 days and then a balance of $40 for 9 days, what is the average daily balance for that 30-day period? 20*21=420 and 40*9= =780 ADB: 780/30=$26 ADB- the average daily balance is just that- the average of the daily balances for all the days in the billing cycle.
Daily interest rate: the interest rate stated with a credit card is always an annual percentage rate (APR). Since there are 365 days in a year, the daily interest rate is the APR/365. APR/366
Monthly Finance Charge Monthly Finance Charge = (ADB) * (APR/365)*(# Of Days in Billing Cycle)
Lets say we have an average daily balance of $456 on a credit card with an APR of 12.9%, over a billing period of 31 days. What would be the finance charge be? 456*(.129/365)*31=$5.00 (to the nearest cent)
