1 Financial Algebra © Cengage Learning/South-Western Warm-UpWarm-Up Grab a paper from the back AND pull out Friday’s notes Manny invests $40,000 in a one year CD paying an annual interest rate of 6.55%. The interest is compounded daily. Find the APY for Manny’s account. Slide 1

2 Financial Algebra © Cengage/South-Western Slide 2 3-6 CONTINUOUS COMPOUNDING Compute interest on an account that is continuously compounded. OBJECTIVES

3 Financial Algebra © Cengage Learning/South-Western Slide 3 limit finite infinite continuous compounding exponential base ( e ) continuous compound interest formula Key Terms

4 Financial Algebra © Cengage Learning/South-Western Slide 4 How can interest be compounded continuously? Can interest be compounded Daily? Hourly? Each minute? Every second? If $1,000 is deposited into an account and compounded at 100% interest for one year, what would be the account balance at the end of the year?

5 Financial Algebra © Cengage Learning/South-Western Continuous Compounding Interest can also be compounded continuously Not just daily, but every second, every micros second – NON STOP Interest that is continuously compounded follows the following formula e = 2.71828 Slide 5

6 Financial Algebra © Cengage Learning/South-Western Slide 6 EXAMPLE 5 If you deposited $1,000 at 100% interest, compounded continuously, what would your ending balance be after one year?
