historical data for analysing pensions
"You could use any of various financial APIs (e.g., Yahoo finance) to get prices of some reference stock and bond index funds.  That would be a reasonable approximation to market performance over a given time span. As for inflation data, just googling ""monthly inflation data"" gave me two pages with numbers that seem to agree and go back to 1914.  If you want to double-check their numbers you could go to the source at the BLS. As for whether any existing analysis exists, I'm not sure exactly what you mean.  I don't think you need to do much analysis to show that stock returns are different over different time periods."
Goldprice.org has different currencies and historical data. I think silverprice.org also has historical data. Check the answers to this Stackoverflow question https://stackoverflow.com/questions/754593/source-of-historical-stock-data a number of potential sources are listed You need a source of delisted historical data.  Such data is typically only available from paid sources. According to my records 20 Feb 2006 was not a trading day - it was Preisdent's Day and the US exchanges were closed. The prior trading date to this was 17 Feb 2006 where the stock had the following data: Open: 14.40 High 14.46 Low 14.16 Close 14.32 Volume 1339800 (consolidated volume) Source: Symbol NVE-201312 within Premium Data US delisted stocks historical data set available from http://www.premiumdata.net/products/premiumdata/ushistorical.php Disclosure: I am a co-owner of Norgate / Premium Data. .INX (the S&P 500 index itself) does not include reinvested dividens.  You can figure total return by going to Yahoo finance, historical data. Choose the start year, and end year. You should find that data for SPY (going back to 1993) will show an adjusted close, and takes dividends into account. This isn't perfect as SPY has a .09% expense ratio, but it's better than just the S&P index. One of the more popular Dow ETF is DIA, this will let you similarly track the Dow while accounting for dividends. I have asked myself this exact same question many times. The analysis would be simple if you invested all your money in a single day, but I did not and therefore I would need to convert your cash transactions into Index fund buys/sells. I got tired of trying to do this using Yahoo's data and excel so I built a website in my spare time. I humbly suggest you try my website out in the hopes that it helps you perform this computation: http://www.amibeatingthemarket.com/ You need a source of delisted historical data.

"Yes it's entirely possible; see below.  If you can't find anything on transfers out (partial or otherwise) on anyone's site it's because they don't want to give anyone ideas. I have successfully done exactly what you're proposing earlier this year, transferring most of the value from my employer's group personal pension scheme - also Aviva! - to a much lower-cost SIPP.  The lack of any sign of movement by Aviva to post-RDR ""clean priced"" charge-levels on funds was the final straw for me.  My only regret is that I didn't do it sooner!  Transfer paperwork was initiated from the SIPP end but I was careful to make clear to HR people and Aviva's rep (or whatever group-scheme/employee benefits middleman organization he was from) that I was not exiting the company scheme and expected my employee and matching employer contributions to continue unchanged (and that I'd not be happy if some admin mess up led to me missing a month's contributions). There's a bit more on the affair in a thread here.  Aviva's rep did seem to need a bit of a prod to finally get it to happen.  With hindsight my original hope of an in-specie transfer does seem naive, but the out-of-the-market time was shorter and less scary than anticipated. Just in case you're unaware of it, Monevator's online broker list is an excellent resource to help decide who you might use for a SIPP; cheapest choice depends on level of funds and what you're likely to hold in it and how often you'll trade." "I can think of one major income source you didn't mention, dividends.  Rather than withdrawing from your pension pot, you can roll it over to a SIPP, invest it in quality dividend growth stocks, then (depending on your pension size) withdraw only the dividends to live on. The goal here is that you buy quality dividend growth stocks.   This will mean you rarely have to sell your investments, and can weather the ups and downs of the market in relative comfort, while using the dividends as your income to live off of.   The growth aspect comes into play when considering keeping up with inflation, or simply growing your income.   In effect, companies grow the size of their dividend payments and you use that to beat the effects of inflation. Meanwhile, you do get the benefit of principle growth in the companies you've invested in.   I don't know the history of the UK stock market, but the US market has averaged over 7% total return (including dividends) over the long term. A typical dividend payout is not much better than your annuity option though -- 3% to 4% is probably achievable.   Although, looking at the list of UK Dividend Champion list (companies that have grown their dividend for 25 years continuous), some of them have higher yields than that right now.   Though that might be a warning sign... BTW, given all the legal changes around buy-to-lets recently (increases stamp duty on purchase, reduction in mortgage interest deduction, increased paperwork burden due to ""right to rent"" laws, etc.) you want to check this carefully to make sure you're safe on forecasting your return."
