OK fellow framers, here's the dilemma- In a prior post I discussed having a "sweep" account where all money in my checking account not needed to cover checks written is transferred to an interest bearing savings account. Until recently, I have not needed to transfer enough money so that the balance falls below the minimum reserve required to avoid service charges. Lately my cash flow requires me to either advance my line of credit, or withdraw so much money from the savings account that I will incur service charges. Assuming that I need $10,000 for a month, 1. The savings account pays 4.56% APR but requires a minimum balance of $10,000 to avoid a $15 per month service charge. Interest earned is taxable but the $15 service fee is deductible. How much interest is earned in 30 days? 2. I have a line of credit that charges 10.912% APR. I calculate that the interest charged to borrow $10,000 is $2.99 per day. Do you agree with this number? The interest paid is a deductible expense. 3. If I take the money from savings, I lose the interest earned and I pay a service charge of $15. 4. If I keep the money in savings, I will earn interest, avoid the $15 fee, but I will need to borrow the money from my credit line. Which is the best thing to do?
