This lesson looks at ordinary annuities, where equal payments or deposits are made at the end of each period. We use timelines and formulas to find the future value, the payment amount needed to reach a goal, and the present value of a stream of payments, including examples with savings plans, sinking funds, and structured settlements. Along the way, we highlight how payment frequency, interest rate, and compounding period all need to line up for the math to work correctly. 0:00 Lesson Intro 3:26 Ordinary Annuity 4:47 Future Value 5:45 Walkthrough Future Value 15:25 Example 1 21:53 Sinking Funds & Example 2 28:37 How to Find Payment Amount 29:30 Example 3 34:05 Present Value 35:10 Example 4 40:36 Common Mistakes 41:15 Key Takeaways 🎓 I’m Dr. B.
