### Algorithm G2

Gummy recently came up with an interesting withdrawal algorithm. It adjusts withdrawals according to the percentage earnings yield, 100E10/P or 100/ [P/E10], and an offset. I have included two algorithms of this sort in each of my Gummy series of calculators. Algorithm G1 makes an adjustment as a percentage of a portfolio's current balance. Algorithm G2 makes an adjustment as a percentage of a portfolio's initial balance.

My implementation is highly flexible.

I used my Gummy 02 calculator in this survey. It is similar to the Deluxe Calculator V1.1A08 except that it includes Algorithms G1 and G2.

Algorithm G2 appears in row 9, columns A through H. It has the form:

Initial Withdrawal Rate = (the contents of cell B9)*(Initial Balance)+(special inflation term G2)*G3*(100E10/P-G4)*(Initial Balance)

Gummy's Inflation Term G2 (0=none,1=PPI, 2=CPI) is in cell I24.
Gummy's Multiplier G3 is in cell F25. This term should a negative number whenever withdrawals are to increase as the percentage earnings yield increases.
Gummy's Offset G4 is in cell I25.

To use the algorithm, set Gummy Algorithm 2? Y=1 equal to 1 in cell F23.

General Procedure

I examined two portfolios. One one consists of 50% stocks and 50% commercial paper. The other consists of 80% stocks and 20% commercial paper.

I decided to apply the algorithm to match inflation according to the CPI. That is, I set term G2 = 2 in all cases.

I decided to look at slopes of 0.25 and 0.50. That is, I set G3 equal to (0.25), which is minus 0.25, and to (0.50), which is minus 0.50.

I set the offset equal to 2.5%. That is, I set G4 = 2.5.

By setting the offset to 2.5%, there is no adjustment when the earnings yield 100E10/P is 2.5%. That is, there is no adjustment when P/E10 equals 40.

When P/E10 equals 20, the percentage earnings yield is 5.0%. The withdrawal rate adjustment is (slope)*(5%-2.5%) in real dollars. This is (0.25)*(2.5%) or (0.50)*(2.5%) depending upon the choice of the slope term G3. These adjustments increase the withdrawal rate by 0.625% or 1.250%.

When P/E10 equals 10, the percentage earnings yield is 10%. The withdrawal rate adjustment is (slope)*(10%-2.5%) in real dollars. This is (0.25)*(7.5%) or (0.50)*(7.5%), which is an increase of 1.875% or 3.75%.

My final step was to adjust the amount in cell B9, the regular input for the withdrawal rate, in increments of 0.1% as high as I could without any failures in 30 years.

I started with initial balances of \$100000. I set the expenses to 0.20%. I adjusted withdrawals (the term in cell B9) to match inflation according to the CPI. I rebalanced the portfolio annually.

I determined the five-year rolling averages of the amount withdrawn at years 5, 10, 15, 20, 25 and 30 for historical sequences starting in 1921-1980.

Tables

Tables with all of these outputs follow this post.

Observations

Using a slope of 0.25 (that is, setting G3 equal to minus 0.25) was consistently better than using a slope of 0.50.

With a slope of 0.50, the withdrawal algorithm over-corrected during the bubble years in the late 1990s. We see this in the low withdrawal amounts at years 25 and 30. (Be careful when looking at sequences that extend beyond 2002 because they include dummy data.)

With a slope of 0.50 and a portfolio with 50% stocks, the (five-year averages of the) withdrawal amounts generally stay above \$2500 with a few exceptions beginning in year 20. With 80% stocks, this lower limit (generally) falls to \$2300.

In both cases, the maximum (five-year averages of the) withdrawal amounts are close to \$6000. Overall, a portfolio with 50% stocks seems to do better than a portfolio with 80% stocks.

With a slope of 0.25, the income floors were \$3300 with 50% stocks and \$3200 with 80% stocks. (There were exceptions.) The ceilings were close to \$5000 in both cases. Once again, the portfolio with 50% stocks generally did better than the portfolio with 80% stocks.

I determined the balances at years 10, 20 and 30 for both 50% stocks and 80% stocks when the slope was 0.25.

When the portfolio had 50% stocks, there were 13 times that the balance fell below \$40000. They occurred in 9 separate sequences. There were 4 times that the balance fell below \$30000. They occurred in 3 separate sequences. There were 3 times that the balance fell below \$20000. They occurred in 3 separate sequences.

When the portfolio had 80% stocks, there were 9 times that the balance fell below \$40000. They occurred in 5 separate sequences. There were 6 times that the balance fell below \$30000. They occurred in 3 separate sequences. There were 2 times that the balance fell below \$20000. They occurred in 2 separate sequences.

This turns out to be one of the better variable withdrawal rate algorithms.

The portfolio with 50% stocks and 50% commercial paper provided a better income stream. The portfolio with 80% stocks and 20% commercial paper provided balances that did not fall as much.

Have fun.
