A Few of the Dangers of On-Line Calculators (Part 2)  Virtually all free on-line retirement calculators exhibit flaws you should be aware of because these flaws contribute to the errors embedded in the results produced by these calculators, and this translates into risk in the retirement planning of anyone who uses them for any purpose other than a quick and dirty glimpse into their financial future.  More...

A Life Cycle Model Financially balancing all the competing factors in your life can be daunting, but a calculator designed for that purpose can be an invaluable tool.  More...

Starting Your Social Security Benefits  When should my wife and I start collecting Social Security?  More...

Retirement Income Requirements  For an optimized retirement plan, your planning process should disregard the time-honored rules of thumb regarding how much income you’ll need in retirement. More...

Contributions to Savings During the Accumulation Phase  This principle is fundamental to accurately modeling the growth and/or decline of your savings over your lifetime and yet, amazingly, PRC is extremely rare in applying it.  More...

Consumption Smoothing  What is “consumption smoothing” and why should I care whether my retirement calculator does it or not?  More...

Traditional vs. Roth IRA I’ve often wondered which was better: traditional IRA’s or Roth IRA’s.  My gut feel has always been that traditional IRA’s were preferable because they paid immediate benefits through the reduction in current-year taxes, but I’ve heard some people suggest that Roth IRA’s might be better in the long run, particularly if Congress raises our taxes prior to taking withdrawals.

A Few of the Dangers of On-Line Calculators (Part 1)  Many people are of the belief that there is little value in attempting to model your future with the precision of a “paid for” calculator because that precision can be overwhelmed by the uncertainty due to such “unknowables” as inflation, market returns, taxes, Social Security and Medicare, life expectancy, etc.  All plans, retirement and otherwise, are based on assumptions on which you can easily perform sensitivity analyses; however, to disregard the influence of certain “knowables” because of the argument that they don’t really matter because of the magnitude of the “unknowables” can lead to significant errors in the range of outcomes produced by your calculator.  PRC’s design philosophy is to get these “knowable” things right because they’re SO EASY TO DO and CAN BE CRITICAL in producing valid projections.    More...

Effects of Simplifying Approximations on Calculator Projections    Simplifying approximations are “front and center” with free retirement calculators and the purpose of this article is to put the spotlight on two of those areas that can cause significant errors in the long term projection of your savingsMore...

A few testimonials...

From Art Kingsley, Leonardtown, MD: “I have used a number of PC-based financial planning software packages, some free, some at a cost. By far, PRC offers the best value and capability! You get what you spend with most free calculators. Not only does PRC calculate a standard of living based on accurate expense and income calculations, its output is fully transparent, easy to follow, and verifiable. If you don’t want to verify, rest assured complex calculations are being correctly applied. You can start with a simple model and add complexity as you go along. With its historic analysis capabilities and superior input and output interface, the Pralana Retirement Calculator now far exceeds the more expensive ESPlanner.  Its capabilities are truly immense.”

From Dwayne C, Gardner, MA.: “I love this program…so powerful yet fairly easy to use. It has made our retirement planning much more a plan as opposed to a guess. I’ve endorsed it on Darrow Kirkpatrick’s website as well as with friends and relatives.  And frankly, this is without a doubt the best $100 I have ever spent…for the price of a nice dinner out, getting to see where you’ll stand financially in the future based on where you are today…it really is a great bargain.”

From Bryan D., Chicago, IL: “PRC is very powerful and easy to use financial planning software. I have tried many other financial planners (including ESPlanner) and for my purposes PRC is the best! PRC allows you to quickly enter your income, expenses, and assets to see a year-by-year projections of future cash flow, taxes, savings, and net worth. It has very robust calculations including factoring in inflation, taxes, social security, and life insurance.  It allows you to quickly change assumptions (e.g. inflation, life expectancy, tax rates) and view different scenarios. I really like the analysis page that graphically shows three different scenarios side-by-side. I highly recommend PRC.”

In actual practice, PRC May Be the Simplest Calculator Available What might “seem” simple can be deceiving.  The “simpler” a calculator appears to be and the “fewer” input fields a user has to complete, the greater the amount of math and “outside the calculator work” the user must perform to be able to provide the “simple” inputs.  Conversely, a calculator with rich data input capabilities and robust calculation capabilities is actually “simpler” for getting to quality results, and from that frame of reference PRC may be the simplest calculator available.
