Each month, a credit + card statement will come with the option for you to pay a + minimum amount of your charge, usually 2% of the balance due. + However, the credit card company earns money by charging + interest on the balance that you don't pay. So even if you + pay credit card payments on time, interest is still accruing + on the outstanding balance.
+Say you've made a + $5,000 purchase on a credit card with 18% annual interest + rate and 2% minimum monthly payment rate. After a year, how + much is the remaining balance? Use the following + equations.
+++Minimum monthly payment += (Minimum monthly payment rate) x (Balance)
+
+ (Minimum monthly payment gets split into interest paid and + principal paid)
+Interest Paid = (Annual interest rate) / (12 + months) x (Balance)
+Principal paid = (Minimum monthly payment) - + (Interest paid)
+Remaining balance = Balance - (Principal + paid)
For month 1, compute the minimum monthly payment by taking 2% of the balance.
+++Minimum monthly payment += .02 x $5000 = $100
+We can't simply deduct this from the balance because + there is compounding interest. Of this $100 monthly + payment, compute how much will go to paying off interest + and how much will go to paying off the principal. Remember + that it's the annual interest rate that is given, so we + need to divide it by 12 to get the monthly interest + rate.
+Interest paid = .18/12 x $5000 = + $75
+
+Principal paid = $100 - $75 = $25The remaining balance at the end of the first month will + be the principal paid this month subtracted from the + balance at the start of the month.
+Remaining balance = $5000 - $25 = + $4975
+
For month 2, we + repeat the same steps.
+++Minimum monthly payment += .02 x $4975 = $99.50
+
+Interest Paid = .18/12 x $4975 = + $74.63
+Principal Paid = $99.50 - $74.63 = + $24.87
+Remaining Balance = $4975 - $24.87 = + $4950.13
After 12 months, the + total amount paid is $1167.55, leaving an outstanding balance + of $4708.10. Pretty depressing!
