How Much To Invest To Retire Early

when you retire you take the risk that you're going to outlive your money and if you retire early you're taking an even bigger risk because you have less time to build up your Investments and they have to last much longer so how do we work out how much we've got to save and what are the risks that go with that and how can we mitigate those risks that's what we'll look at in this video now don't forget if you do enjoy our content please do subscribe to our channel it's free and that way you won't miss any new videos so let's look at how much to invest to retire early in a bit more detail so how do we work out how much it takes to retire well the analogy I really like is that of harvesting corn and that's because the idea of a sustainable crop is very intuitive so let's say that we start off with an initial investment an initial crop if you like of a hundred cobs of corn we plant it then we Harvest it and we end up with 20 more than we started with and that's because we've got an additional 20 Corps that that in turn means that if we Harvest that 20 percent and eat them and then plant the rest of the hundred reinvest it then we should have a perpetually sustainable crop of corn now if we eat more than 20 cobs we're going to have less each year in future and eventually the size of our crop will dwindle to zero if we eat less than 20 carbs then we'll have extra and our crop will build up forever so this is the intuition behind a sustainable portfolio if it's growing at seven percent per year then if you withdraw less than seven percent every year you should have a sustainable portfolio that in theory lasts forever however there are some caveats later as we'll see now there are two phases to investment the first one is accumulation and the second one's drawdown so if we plot our wealth over time in terms of our savings and our investments usually it looks a little bit like this initially we start off with very little money then we accumulate wealth over the course of our life then we retire and start to eat our savings so in this case in drawdown the size of our pot dwindles over time now this box on the right hand side shows you the assumptions I've made and it's fairly easy to make a spreadsheet for yourself to create these calculations I've provided one for our members some time ago the rate of accumulation depends on your initial wage and the wage growth that you get every year and another key number is the rate of investment return which I've assumed is seven percent that's fairly conservative as we'll see then the size of the pot dwindles based on your desired income in retirement now unfortunately with this pot the age when your money Runs Out is 84. and the average life expectancy in the UK is 80 six so we can tell that this part probably is not going to work out now there are various ways we can increase the survival time of the pot we could reduce our desired income spend less in retirement we could increase the amount of our income which we save every month or we could start investing sooner or hopefully we could increase our salary or we could retire later but for this example what I've done in the spreadsheet is to increase the savings amount and here I've doubled it to 40 percent now it would be very challenging to do that but the consequence is that now we have much more in our retirement pot at retirement and furthermore this is a Perpetual part it never shrinks and that means that we're probably going to have a legacy for our children but you might be looking at this curve beside me and thinking wait a minute that looks nothing like my portfolio which is all over the place well you'd be exactly right and that's the problem with these types of spreadsheets so I've made a new tool for our members which takes into account volatility to do that we need to do Monte Carlo sampling so for members this is what their dashboard looks like on our website and you can scroll down to get to the goodies so you can see the courses you're registered for there's a list of all the content which is available which you can search and we've now got the new trackers and I've added these tools as part of those trackers so let's launch those and the new one is right at the top it's called saving and retirement with lots of these Wiggly lines that's the Monte Carlo so what I've done here at the top is to provide an explanation of what the tools do with some example returns and volatilities for various types of portfolio ranging from 20 equity and 80 bonds all the way up to 100 Equity so you do have to make assumptions about returns and historically equities returned about nine percent that's certainly true of the live strategy funds over the last 10 years or so you also have to make a guess about the volatility that's how much the price is fluctuate weight on your Investments so that's what this is providing so you know what numbers to put in further down on the page then thanks to Laura's feedback there are some pop-ups that appear beside each of these inputs to the simulations so you can see there's a savings forecast that's for the accumulation phase and a drawdown forecast and that's for the drawdown phase so to kick off the simulations you just click this button to rerun the simulations and these are the results of those simulations so you're probably thinking Monte Carlo what on Earth is that well let me just illustrate that with one example if I reduce the number of simulations here and we reduce it all the way down to three simulations and rerun the simulation this is a single projected path for drawdown assuming you started off with six hundred thousand pounds with all of these other assumptions now notice that for this simulation the size of the pot gradually increased so you might think okay well we've got a Perpetual pot here one which never shrinks but what if that's not true what if the volatility of your portfolio in some cases might create an unlucky streak where for several successive years Equity markets fall you're forced to crystallize that loss because you're in drawdown and eventually the size of the pot shrinks to zero could that happen well let's try more simulations so I'll increase the number of simulations to 400 and rerun it now what you can see are these weird lines which shrink down to zero for the size of your investment pot and what it's telling me is that for 74 of the simulation is about three quarters of them the money didn't run out on this investment pot but for a quarter of them it did now is that an acceptable risk for you personally I'd be very cautious about using this portfolio if the assumptions are right and even though the most likely outcome the median outcome is that the pot lasts more than 30 years the risk of 25 percent that it doesn't do that is enough to make me feel think I have to change my assumptions so how about increasing the size of our portfolio to seven hundred thousand well now the chance of running out of money is just 18 and I think that's much more acceptable a one in five risk or if we want to be even more certain let's increase it to 800 000 and now the chance of not running out of money is just about ten percent so the spreadsheet would only have shown you the most likely path and it wouldn't have taken into account the uncertainty in your assumptions and the effects of volatility so that's why I think these tools are really valuable they let you take into account the uncertainty in your Investments and they show you the trade-off between risk and return so this was the drawdown forecast you can do the same thing for the saving forecast where here you're building up the portfolio and we now know that we want 800k in the pot so let's run our simulation we're going to be investing for a 20-year period and the median size of our pot is only 56 000 pounds so that's well below what we need bring you can see we're only saving one thousand pounds per year let's increase that to say twenty thousand and what I've assumed is that the savings increase over time because our wage is increasing at four percent so re-run the simulation and now the value of our investments in year 20 look much more respectable the median is six hundred and eighty thousand but again you can see that the fifth percentile the low probability tail outcome is that we're only going to have about four hundred and thirty thousand and the chance of that is one in twenty so again I'm going to have to revise my assumptions let's say that now I'm going to increase the annual savings up to thirty thousand a year well now the central case is that we're going to have 936 000 pounds with the fifth percentile being at 563. so I'd still be a little bit uncomfortable that we're not going to meet our Target in time for retirement but you can see how this Monte Carlo process is useful because it shows you the error bars you can see the the tail risks and you can increase the amount you need to ensure that you'll have enough even if volatility works against you and you're unlucky so now let's apply this tool to build up one of those Perpetual pots of say 800k but we're assuming that you're going to start at age 30 and you've only got 10 years to get there well if we have initial Savings of 10 000 per year with that 10-year retirement period there's no way we're going to get there we're going to have to dial up our savings amount substantially in fact we'd have to save 70 000 every year in order to get there so if instead we'd started off with 100K maybe from a relative now we'd only need annual Savings of sixty thousand in order to reach a median pot of 800k but notice that even now the tail risk is that we're not going to get there the fifth percentile is only 520k so I think people underestimate exactly what's required in order to accelerate the buildup of the their savings you're either going to need a big lump sum or you're going to need to make absolutely brutal savings to save as much of your income as possible now I think many people underestimate the role of luck in investment some people have an incredible process a great ability to invest but they could just be unlucky and what these tools allow you to do is to mitigate the risk from unlucky returns by doing these simulations which take those tail risks into account now if you
