            savings,                                                 checking accounts,
            cds (certificate of deposit),                     credit card rates,
            student loan rates,                                   house loan (mortgage) rates,
            and car loan rates.
    Write up your findings and be sure to include the source of each rate.

  • Tues Oct 10 Begin lump sum formula via compounding annually. Then compounding quarterly, and then the general lum sum formula. Compounding monthly. Real-life bank situation. Past student was told that her c.d. will be compounded monthly at 8% for 8 months, and is told that this 8% will apply each and every month. Let's say that she put in $1000. How much would her c.d. be worth at the end of 8 months if
    -the bank will compound 8% each and every month (ie 96% per year!)
    -the bank means that 8% is the annual rate.
    Which did the bank really mean? Discuss other possibilities for unknowns in the lump sum formula - the time length, the rate, or the number of times compounding per year, and set up the Simpsons thrifty saver account for Monday.

  • Thur Oct 12 Review lump sum formula and the philosophy we used to come up with it and review how much we will end up with if $100 is deposited into an account and left alone for 25 years, compounded monthly at 5%. Compare to $100 deposited every month into an account and left alone for 25 years, compounded monthly at 5%. Work towards the periodic payment formula and compare the philosophy to the lump sum formula derivation. Transparencies from class $100 is deposited each month for 12 years into an account compounding 5% monthly. How much do we end up with? We'll do an exercise to show that the number of digits we use does matter! 100 is deposited each month for 12 years into an account compounding 5% monthly. What do we have at the end? The interest rate is .05/12=.004166666... Each group of 3 used a different number of digits and rounding versus truncation methods (ie .004,.0041, .0042,.00416, .00417,.004166, .004167, .0041666, .0041667 ). The group helped each other with their calculators and made sure that they all came up with the same answer. We compared the final answers to show that we should never round until the final answer. If time remains then work on problems and then Jane and Joan.
