4.1 Lian Chen’s Savings and Banking Plans
Lian Chen is a registered nurse who earns $3,250 per month after taxes. She has been
reviewing her savings strategies and current banking arrangements to determine if she
should make any changes. Lian has a regular checking account that charges her a flat fee
per month, writes an average of 18 checks a month, and carries an average balance of $795
Of the many checking accounts Lian’s bank offers, here are the three that best suit her
needs.
• Regular checking, per-item plan: Service charge of $3 per month plus 35 cents per check.
Lian’s bank also offers CDs for a minimum deposit of $500; the current annual interest
rates are 3.5 percent for 6 months, 3.75 percent for 1 year, and 4 percent for 2 years.
Critical Thinking Questions
1. Calculate the annual cost of each of the three accounts, assuming that Lian’s banking
habits remain the same. Which plan would you recommend and why?
a. Regular checking, per-item plan: Service charge of $3 per month plus 35 cents per check.
Monthly charge $3 + Per check charge $0.35 * 18 = $9.30 per month
Total annual charge, monthly charge is waived for 9 months, $27.90 of $ (3 * $9.30)
Since Lian’s balance is always under $1,500, she will have monthly charges each month.
Annual monthly service charge $7 * 12 = $84; Less interest earned $795 * .0305 = $24.25
Net annual cost = $59.75
From Exhibit 4.8, interest of 3 percent compounded daily equals an effective rate of 3.05%.
