Answer:
The loan's approximate effective interest rate is 6.17%.
Step-by-step explanation:
Interest expense = Short term bank loan * Short term bank loan interest rate = $500,000 * 6% = $30,000
Interest income = Balance in the account checking account * Interest rate on checking account balance = $20,000 * 2% = $400
Net interest expense = Interest expense - Interest income = $30,000 - $400 = $29,600
Available amount = Short term bank loan interest rate - Balance in the account checking account = $500,000 - $20,000 = $480,000
Effective interest rate = Net interest expense / Available amount = $29,600 / $480,000 = 0.0617, or 6.17%
Therefore, the loan's approximate effective interest rate is 6.17%.
