Amortizing loan Weighted-average life[edit] Main article: Weighted-average life. The number weighted average of the times of the principal repayments of an amortizing loan is referred to as the weighted-average life (WAL), also called average life. It's the average time until a dollar of principal is repaid.

What is 'Weighted Average Life - WAL' Weighted Average Life - WAL. What is 'Weighted Average Life - WAL'. The weighted average life (WAL) is the average length of time that each dollar of unpaid principal on a loan, a mortgage or an amortizing bond remains outstanding. Calculating the WAL shows an investor, an analyst or a portfolio manager how many years it will take to receive half the amount of the outstanding principal. Next Up.

Mean The weighted arithmetic mean (or weighted average) is used if one wants to combine average values from samples of the same population with different sample sizes: The weights represent the sizes of the different samples.

- A weighted average takes into account how many of each age there are; (3x10 + 5x8 + 1x6)/9 = 8.4. (notice you divide by total number of people not the number of ages represented as previously).he weight is often NOT arbitrary as in the above example. If a bank wants to know the average interest rate for its portfolio, the weight is the principal balance of each loan. If there are only two loans, one for $999,990 at 6% and one for $10 at 12%, the AVERAGE RATE is 9% [(6 + 12)/2].

- Add up the weighted years and the total weighted earnings. In the example, the weighted years total 15 (5 + 4 + 3 + 2 + 1) and the total weighted earnings are $1,810,000. Step 4. Divide the total weighted earnings by the weighted years to find the weighted-average five-year net income.Following the example, divide $1,810,000 by 15, which equals $120,667. simple average of the last five years' earnings gives equal weight to each year, whereas the most recent results are more likely to reflect current business performance. Weighting the average net income is a way of giving more importance to the most current results. Step 1.

Weighted Average Rate this weighted average definition... A weighted average is an average that adjusts for the frequency of individual values. Here's an example of a weighted average: suppose 20 people are asked to estimate the number of goats Farmer Jones has. One says 4; seven, 5; eleven, 6; and one, 30.hus the weighted average is [(1x4)+(7x5)+(11x6)+(1x30)]/(20)= 6.75. In a weighted average, values that are unusual have relatively little effect. In the example, the weighted average was raised relatively little by a very high estimate of 30 goats, because only one person made that guess.

How to Calculate the Weighted Average Life for Bonds Multiply each of the bond's payments by the number of years until the issuer pays each of them. For example, if a bond pays $1,000 after one year, $2,000 after two years and $4,000 after three years, multiply $1,000 by 1 to get $1,000, multiply $2,000 by 2 to get $4,000 and multiply $4,000 by 3 to get $12,000.

duration vs. weighted average life? Search form. duration vs. weighted average life? I’m trying to understand the difference of duration and WAL in terms of how they are calculated (not their ultimate use). From what I think I understand, duration is calculated as the time to the maturity weighted by the present value of the cash flows (principal and interest). WAL is the time to maturity weighted by undiscounted principal flows.

What is 'Weighted Average Life - WAL' Weighted average life = $91,000 / $23,000 = 3.96 years. The largest payment is the final payment, so the WAL is close to the total five-year term of the bond. If, for example, the year two and year five payments were switched, the weighted average life would be much lower: Year 1 = 1 x $1,000 = $1,000. Year 2 = 2 x $10,000 = $20,000

Calculating Weighted Average: Method, Formula & Example Most classes usually assign a different weight or value to papers than to homework assignments, quizzes and tests. In this case, you might need to use a weighted average, which is an average where each value has a specific weight or frequency assigned to it, to calculate your grade. There are two main cases where you will generally use a weighted average instead of a traditional average.

What is 'Weighted Average' Loading the player... Weighted average is a mean calculated by giving values in a data set more influence according to some attribute of the data. It is an average in which each quantity to be averaged is assigned a weight, and these weightings determine the relative importance of each quantity on the average.

What the Heck is a âWeighted Averageâ? In short, the term “weighted” is simply meant to indicate that separate groups of numbers have different numbers of elements and thus should be weighed differently. Let’s say one group of numbers has an average of 4, and a second group of numbers has an average of 6.

The most commonly used measure of life expectancy is at birth, which can be defined in two ways. Cohort LEB is the mean length of life of an actual birth cohort and can be computed only for cohorts born many decades ago, so that all their members have died.

What is the average annual return for the S&P 500? Things are changing ever more rapidly. The companies that made up the S&P 500 in 1920 had an average life of 70 years before they died (think Eastman Kodak, Woolworth, Union Carbide, etc.). Today the average life of a company in the S&P 500 is less than 20 years and is approaching 15 years. Let me ask you a question.
