Flexible Retirement Planner Support Forum

Does anyone have a source (i.e. Morningstar, Vanguard etc.) that they utilize for "Custom Modeling" that provides the Returns and Standard Deviation of Equity to Fixed Income of:

70 / 30 Allocation
60 / 40 Allocation
50 / 50 Allocation

Thanks,

Anyone with an answer should feel free to respond, but since this forum is viewed mostly by people looking for answers to questions about the planner, the traffic is relatively light.

Below is URL for a thread and link to historical backtesting spreadsheet.
https://www.bogleheads.org/forum/viewto ... =10&t=2520

The tab named Analyze_Portfolio will give you CAGR and STDEV for a custom portfolio you specify.

Just realized the download link at top of the linked thread is not current. If you go to the last page of discussion, you can find the latest version.

Thanks for doing the digging over at bogleheads.org and for following up with this info.

Simba's spreadsheet looks like it'd be a great tool for this sort of analysis. I hadn't looked at it in a while. They've really beefed it up over the years and it's great that they seem to be keeping the data current.

You're welcome, Jim and others.

I downloaded version 19d of the spreadsheet and set it to 35/15/45/5 (US/Intl/TBM/Cash) -- my version of 50/50 allocation.

Nominal growth 1970-2019 was 8.72%. Real growth (after inflation) was 4.63%. Being a pessimist I am using Real growth *and* inflation of 3% in FRP. In effect inflation is applied twice in my example (I think). Historical results seem too rosy for me at this time.

Target2019 - I mistakenly thought you were the OP. I just realized you're something of a regular around here.

Double thanks for jumping into this thread with such a great answer. - Jim

Thanks so much...the spreadsheet is awesome and can be used to run multiple scenarios in FRP.

BTW, new to FRP and the forum...great tool and great site.

Here is a link to an inflation tool I have used for analysis.

I may be an OP, but I am not the OP!

The Simba Backtesting sheet has always seemed useful since one can farm the data and do what you want with it.

BTW there is inflation data series in the workbook too.
