While my recent posts on sequence of returns risk during drawdown and bond to equity volatility vs returns are still fresh in our minds let’s return to our retiree's who are another drawdown year on having now been in wealth drawdown for 8.5 years.
For long term consistency I want to make as few changes to the original assumptions as possible however this year one change would seem prudent. To represent the equities portion of the portfolios I use the iShares FTSE 100 UCITS ETF (ticker: ISF) as a proxy. This year that ETF has become an iShares Core Series ETF resulting in a TER change from 0.4% to 0.07%. I'm going to allow that change to occur within the assumptions as it simulates a real change that an investor might see. All other assumptions are unchanged from the original post. Re-emphasising some of the key assumptions:
I've picked a 4% withdrawal rate because of the often quoted (dangerously in some cases IMHO but that’s for another day) 4% safe withdrawal rate rule. The 50% equity : 50% gilts portfolios (the red lines on the chart) are the closest representations to the 4% rule with obvious differences being that:

Re-emphasising some of the key assumptions:
- Our retiree’s are drawing down at the stated withdrawal rate plus fund expenses only. This means any trading commissions, wrapper fees (eg ISA, SIPP fees), buy/sell spreads and taxes have to be paid out of the earnings taken. For example, our 2% initial withdrawal rate retiree's are actually drawing down at between 2.10% and 2.21% dependent on the asset allocation selected.
- All calculations are in real (inflation adjusted) terms meaning that a £ in 2006 is equal to a £ today.
- 6 Simple UK equity / UK bond portfolios are simulated for our retiree's. The UK equities portion is always the FTSE 100 where as mentioned above the iShares FTSE 100 ETF (ISF) is used as the proxy. For the bonds portion a simulation is run against UK gilts (FTSE Actuaries Government Securities UK Gilts All Stock Index) where the iShares FTSE UK All Stocks Gilt ETF (IGLT) is used as the proxy and the bond type I prefer in my own portfolio, UK index linked gilts (Barclays UK Government Inflation-Linked Bond Index), where the iShares Barclays £ Index-Linked Gilts ETF (INXG) is used as the proxy.
- The wealth accrued at retirement (the 31 December 2006) is £100,000. To simulate a larger or smaller amount of wealth just multiple by a constant. For example if you want our retiree’s to have £600,000 just multiply all the subsequent pound values by 6.
A 4% Initial Withdrawal Rate

I've picked a 4% withdrawal rate because of the often quoted (dangerously in some cases IMHO but that’s for another day) 4% safe withdrawal rate rule. The 50% equity : 50% gilts portfolios (the red lines on the chart) are the closest representations to the 4% rule with obvious differences being that:
- the 4% rule was for a US punter with US based investments while I'm simulating UK punters with UK based investments; and
- the 4% rule doesn't consider fees where I'm capturing the OCF's of the ETF's which makes my withdrawal rate very slightly higher.
