The Employee Benefit Research Institute (EBRI) has a good collection of calculators here:

Their Ballpark Estimate retirement calculator is one of the better non-Monte Carlo calculators out there. It strikes a good balance between useful input parameters and simplicity.

Our fellow poster tfb's calculator for Tax-exempt versus Taxable Bond/MM Funds.
Most of the other web-based calculators are inaccurate. Tfb's calculator also lets you factor in AMT and whether or not you itemize.

401 (k) planner

Nice little java calculator here for playing 'what if' with various 401(k) scenarios, and get a real time feel for what various changes can do to the outcome, i.e. inflation rate, savings rate, when you retire, etc.

You can tell it to include or not include SS...

Like most of these calculators, you can't look under the hood at how it does it's calculations, but the results seem reasonable with the inputs I selected.

Backtesting Spreadsheet

Post by simba » Mon Oct 29, 2007 9:38 am

Disclaimer/Caution/Caveat Emptor: Use these only for Entertainment purposes. Please do not change your asset allocation purely based on historical performance. This was a fun project and please treat it such.

I created a backtesting spreadsheet based on the excellent work done by Trev H, Gummy and other diehards and discussed it on this Thread.
You can directly download Excel (ver rev6j) or the Openoffice (ver rev6g) spreadsheets.

A slight variation of these spreadsheets can be found at Gummy's site Here and Here

Russell created an excellent (visual) Fama French Calculator that he discussed on this Thread.
You can play around with Russell's Calculator

fundtalker123 created some cool contour plots based on different asset allocations. He discussed this Here.
You can also check out the contour plots that fundtalker created at gummy's site.

Best Regards,

Mel posted above about The Flexible Retirement Planner by Jim Richmond.

I wanted to add that this calculator allows you to try both flexible decision spending rules during retirement......and you can try Bernicke's reduced spending plan in retirement if you input your spending.

I think we have a record for the LEAST number of posts. It is hard to get less than 0 (zero) posts as shown above by jessetc. Of course, replying to someone in a thread four and half years later may qualify as a negative post.
