What is Balance?
This is defined as the difference between the sum of the debit and credit entries in a financial period.
Balance on the card = Opening balance + Purchases - Payments
= 424.86 + 78.10 + 27.97 + 8.16 + 46.07 - 55.25 - 20
= $509.91
Opening balance in a 30-day billing cycle becomes:
= 509.91 x (1 + 13.13%/365 days x 30 days)
= $513.74
