Your monthly Tab charge is always rounded up to the nearest dollar. When your Tab balance divided by 24 is not equal to a whole number, the monthly Tab charge is rounded up to the nearest dollar. All this means is that you pay off the Tab sooner than 24 months. Your final monthly Tab charge will be adjusted so that you only pay the remaining amount on your Tab balance – no more, no less. If you put $300 on the Tab, your monthly Tab charge will be $13 (rounded up to $13 from $12.50). You will pay a monthly Tab charge of $13 for 23 months and on your 24th monthly bill, the remaining Tab balance will be $1, which is your final Tab charge.
