  1. Compound Interest and the Net Operating Income Chapter 7

  2. Chapter 2: Analysis of Gross Income Chapter Objectives • Define the comparisons between simple and compound interest. • Describe how to forecast future cost based on a compounded rate. • Identify which column of compound interest is applicable to developing the Income Approach. • Describe the impact of time on money.

  3. Chapter 7: Compound Interest and the Net Operating Income Chapter Introduction • Compound Interest • Answers the benefit of borrowing opposed to paying cash • Opportunity costs of an investment through debt leveraging • A useful technique that incorporates the assumption of change over time when performing an appraisal

  4. Chapter 7: Compound Interest and the Net Operating Income Compound Interest vs. Simple Interest • Compound Interest vs. Simple Interest • Difference in how the interest is applied • Simple interest loan • Divide the interest to be charged in equal payments over the life of the loan • Compound Interest Loan • Payments made will majorly reduce the interest charged on the loan first • Principal will be proportionately increased minimally over the initial years

  5. Chapter 7: Compound Interest and the Net Operating Income Compound Interest vs. Simple Interest (cont.) Simple Interest vs. Compound Interest Comparative Recapitulation See Page 83 to review a Comparative Debt Reduction: Simple Interest vs. Compound Interest Method

  6. Chapter 7: Compound Interest and the Net Operating Income Compound Interest Chart: The Time It Represents • Compound Interest Chart • Impact of time on $1 can be seen from the future and present time perspective • See Page 83 to review the chart revealing an explanation and overview of each symbol present in the compound interest chart

  7. Chapter 7: Chapter Title Compound Interest Chart at 6% Interest • Examine the 6% Compound Interest Chart presented on Page 84 • Based on an annual rate of compound interest • Every number represents the impact of time on $1 at a specific compounded rate of interest • The first 3 columns are based on future value or the forecasting of what $1 will be • Sinking Fund Factor • Chart forecasts what annual payments are needed to reach $1 if the payment is deposited in a compound interest bearing account • Compound interest problems are solved by multiplying a specific number of dollars by the applicable factor.

  8. Chapter 7: Compound Interest and the Net Operating Income Working with the FW1: Time and Rate of Interest Impact on $1 • FW1 • Reveals the future worth of $1 • Result of a future amount or value of $1 deposited and left in the interest bearing account

  9. Chapter 7: Compound Interest and the Net Operating Income Apply Your Knowledge 7.1 Working with the compound interest charts (3% and 5%) provided on Page 85, answer the questions that focus on the forecasting of $1 utilizing FW1 factors. • What would $1 be worth if it were deposited today in an interest-bearing account that paid 5% over a 10 year term? $1 x 1.628895 = $1.63 • The roof has a cost new of $4,200. What will the roof cost in four years, if inflation is rising at a compounded rate of 3%? FW1 Factor 1.125509 Roof Cost Today x $4,200 Future Cost $4,727.14

  10. Chapter 7: Compound Interest and the Net Operating Income Apply Your Knowledge 7.1 (cont.) • The monies received from an unexpected windfall were $12,000. If that money is deposited in an interest-bearing account at 5%, how much money would be available in seven years? 1.407100 (FW1 Factor) X $12,000(Dollar Amount of Windfall) $16,885.20 (Money Available in Seven Years) • There were two investments being looked at, one at a slightly higher risk than the other. What is the difference in gain between 3% and 5% over six years on a $2,500 deposit? FW1 Factor @3% 1.194052 @5% 1.340096 Amount of Deposit x 2,500x 2,500 Future Value of Deposit $2,985.13 $3,350.24 $3,350.24-$2,985.13=$365.11 (Difference in Gain)

  11. Chapter 7: Compound Interest and the Net Operating Income Working with the FW1/P: Time and Rate of Interest • FW1/P • Future Worth of $1 per period • A compound interest factor that forecasts the future value of level stream $1 deposits each period of the holding term of the investment • The FW1/P $1 will be deposited each year into a compounded rate of interest account.

  12. Chapter 7: Compound Interest and the Net Operating Income Apply Your Knowledge 7.2 Using the FW1/P Column provided on Page 86 answer the following question. • Using data from the excerpted FW1/P column above, find the difference between $1 deposited each year in an interest bearing account compounding at a rate of 6% over a five year period versus continuing the same dollar deposits in the account for eight years? Solve by going to the second column, years 5 and 8; find the future value of $1 deposited each year for 5 years and 8 years to see the difference. The dollars will grow additionally $4.77 over the three-year term difference at 6%. (10.636628-5.866601 = 4.77)

  13. Chapter 7: Compound Interest and the Net Operating Income Apply Your Knowledge 7.3 Working with the compound interest charts (3% and 5%) provided on Page 87, answer the questions that focus on the forecasting of $1 utilizing FW1/P factors. • What would be the balance if $1 was deposited annually into an interest-bearing account that paid 5% over a 10 year term? FW1/P = 12.577893 • Deposits of $1,100 are planned to be annually deposited each year for seven years, at a compounded rate of 3%. How much money will be available in the future? 7.662462 (FW1/P) X $1,100 (Annual Deposit) $8,428.71 (Money Available)

  14. Chapter 7: Compound Interest and the Net Operating Income Apply Your Knowledge 7.3 (cont.) • What is the difference in gain between 3% and 5% compound interest over four years on a $500 annual deposit?

  15. Chapter 7: Compound Interest and the Net Operating Income Time and Rate of Interest Impact on $1: Sinking Fund Factor • Sinking Fund Factor • Used to calculate how much money needs to be held in a reserve account • Requires the need to identify the future cost at the time the short-item needs to be replaced • The factor is identified based on the number of years and the compounded rate • When multiplied by that future cost, the factor will conclude the annual amount that needs to be held from the income stream and deposited into an interest bearing account

  16. Chapter 7: Compound Interest and the Net Operating Income Apply Your Knowledge 7.4 Using the Sinking Fund Factor Column provided on Page 88 answer the following question. • What is the difference between the amount that needs to be deposited each year in an interest-bearing account compounding at a rate of 6% over five years versus eight years if $1 is needed in the future? Solve by going to the second column, Years 5 and 8, and find the sinking fund factor of deposits each year for five years and eight years to see the amounts needed to reach a future $1. The difference in the annual deposits necessary to reach $1 is $0.08 (0.177396 – 0.101036 = 0.08).

Chapter 7: Compound Interest and the Net Operating Income Apply Your Knowledge 7.5 Working with the compound interest charts (3% and 5%) provided on Page 89, answer the questions that focus on the forecasting of $1 utilizing SFFfactors. • How much money would need to be deposited annually in an interest-bearing account paying 5% over a ten-year term, in order to reach $1? SFF = $ 0.079505 or 8¢ • In three years, a couple will have a dependent who will require $4,000 in order to attend a school of fine arts for one year. The cost of moving expenses and a housing deposit will be another $14,000. How much money will need to be deposited in a 5% compounded interest account to reach the amount necessary? 0.317209 (SFF in Three Years @5%) X $18,000 (Total Amount Needed in Three Years) = $5,709.76 (Money to Deposit)

  18. Chapter 7: Compound Interest and the Net Operating Income Apply Your Knowledge 7.5 (cont.) • What is the difference in deposits between 3% and 5% compound interest over nine years, when the goal is to end with a sum of $10,000?

At which rate would the higher yield be gained? PW1 in 6 yr.’s @3% 0.837484 @5% 0.746215 FV of Property x $75,000.00x $75,000.00 Present Value $62,811.30 $55,966.13 Difference $62,811.30 - $55,966.13 = $6,845.17 The higher yield would be gained a 5%.
