Answer:
1. The unpaid balance at the end of the cycle is $840
2. The interest charged in this billing cycle is $15.17
3. The new balance at the beginning of the next cycle is $835.17
Step-by-step explanation:
Assuming that a purchase of $550 was made on the last day is not debited in same day, but in 2 days later as almost banks and credit card providers currently do.
The unpaid balance at the end of the cycle = Unpaid balance at beginning $950 + new purchase $57, $75, and $113 – credited amount $355 = $840
For credit card, the interest is charged on unpaid balance at the end of the cycle.
The interest charged in this billing cycle if interest charge on $950 in 23 days; and then charge on $595 in 7 days from 24th to 30th because $355 was credited to the account on the day 24.
= $950x20.99%/360x 23 days + $595 x20.99%/360x 7 days = $15.17
The minimum payment on the credit card is the greater of $20 or 2% of the unpaid balance; 2% of unpaid balance $840 is $16.8. Then the minimum payment required for this billing cycle is $20.
Thus the new balance at the beginning of next cycle = unpaid balance at the end of previous cycle $840 + interest charged $15.17 – minimum payment credited $20 = $835.17
