I keep forgetting you guys are sitting in May. The amortization table might be a little ambitious in your early studies. Sorry about that. I keep practicing those so I can make sure I have them down. The table would look like this
Payment # 1
Paid Amount = 100,000 * .025 = 2,500
Interest Expense = 105,000 * .02 = 2,100
Premium Amortization = 2,500 – 2,100 = 400
Bond Premium = 5,000 – 400 = 4,600
Carrying amount = 105,000 – 400 = 104,600
Except they would go across as columns then use the new carrying value to calculate the next interest expense, while the paid amount will always be 2,500 at each payment period.
