Frequently Asked Questions

Many so-called “planning tools” are simply aggregators. They pull together your account balances each time you sign in and show you your current balance year-to-date. That’s handy, especially when you have accounts spread around at different brokerage companies where you can’t see them all at once.

But that’s not financial planning. It’s simply telling you something you already more or less know (or could create in a spreadsheet) and it’s a convenience feature, not a life-cycle planning feature.

So what is the fundamental difference between conventional planning and MaxiFi Planning (what we call economic planning)?

Conventional planning builds its model around user-entered spending amounts. The user of conventional planning software is sooner or later asked some form of the following question: “How much do you need to live on in retirement?” If that question sounds familiar, you are using conventional planning software. Sometimes users know how much they need, sometimes they use a rule of thumb like 80% of pre-retirement income, sometimes they just guess. At any rate, the variable comes from outside the model itself and thus becomes a premise of the model not an outcome of the model. MaxiFi’s economic planning works a different way: it takes your inputs and discovers your allowable annual spending level. Instead of asking you to tell the program how much you need to live on, MaxiFi discovers and reveals to you how much is available. This annual spending allowance is new information. It’s not something you could ever discover on your own without complex programming. Every item in MaxiFi's planning model impacts every other item, and they all work together to reveal in MaxiFi the household’s annual spending level.

Why does this difference matter?

  1. A calculated spending level becomes a reliable benchmark to use when comparing models
  2. A calculated spending level is new information, not simply repackaging (or creating a chart of) known information
  3. A calculated spending level is a mathematical outcome, a fact about a household’s economy, not a wish, goal, hunch, or rule of thumb.
  4. A calculated spending level is including future receipts like Social Security, pensions, taxes, Medicare B, retirement withdraws, mortgages, and on and on. When one item, even the most trivial item changes, the calculated spending level is refreshed.
  5. A calculated spending level focuses on smooth, sustainable spending, not savings targets.
  6. A calculated spending level provides a practical, meaningful answer to financial planning question (compared to the abstraction of a simple Monte Carlo conclusion).

MaxiFi does all this with a level of detail and precision not typically found in other planning software.


  • Calculates state and federal taxes based on income for each year
  • Calculates actual Social Security benefits and finds optimal benefit collection strategies
  • Does not build its model around user-specified premise such as how much one needs to live on in retirement
  • Dynamically incorporates every future receipt and expense in a way that displays the meaningful difference it makes in annual spending starting in the current year rather than a Monte Carlo abstraction like “87% chance of success.”
  • MaxiFi’s sophisticated Monte Carlo allows you to run a risk analysis on your model showing the upside potential and downside risk to your annual spending level, not simply to an isolated pool of retirement assets.

MaxiFi gives you all this without any compromise. Our company doesn’t sell your data, we don’t manage your assets and make money from fees. We’re simply in the business of writing software to help people make smarter financial decisions.

MaxiFi Planner has been updated to incorporate the provisions of the SECURE Act of 2020 and the Tax Cuts and Jobs Act of 2017. Learn more about the TCJA changes and how you can use MaxiFi to see their impact on your lifetime finances.

MaxiFi is a long-range planning tool that helps you to build life-cycle models (i.e., models that reflect various periods of saving and dissaving; children in the house, children left home; working, retirement, etc.). It is not primarily an asset allocation tool or an investment analyzer that shows historical yield, standard deviation, or any other kind of data you might explore about funds or asset classes. This kind of analysis is typically free at your brokerage or investment company like Fidelity or Vanguard. A free tool like portfolio visualizer is very powerful in this regard.

The very powerful and free tools that do statistical analysis, backtest analysis, asset correlations, factor analysis, portfolio optimization are useful in context but in no way capable of doing what our software does which is to reveal an endogenous lifetime spending amount, accounting for you changing federal and state taxes, your future receipts like Social Security, pensions, declining mortgage, inflation . . . pretty much any sort of expense or receipt with whatever tax consequence you can imagine and account for that in its calculation of smooth annual discretionary spending over a lifetime. This spending amount can serve as a mathematical benchmark against which you can measure the impact of any financial event: How does spending an annual sum of $36 or $36,000 15 years from now change my spending this year and every year thereafter? How much is this lifetime annual spending changed if I postpone SS til I'm 70? If I assume an average nominal return on my retirement assets of 6% instead of 5.75%, how much would my annual discretionary spending change? The list of such "what if's" is up to the imagination.

Most other financial planning software companies have other ways of making money, usually by managing and investing your assets or selling you financial products such as life insurance. Our sole focus is developing personal financial planning software to provide you with a solid, detailed financial plan you can trust.

The free tools also use simplistic, outdated "rules of thumb" and lack precision when it comes to crucial aspects of your plan, such as Social Security benefits and state taxes. Because our focus is on planning, we constantly work to improve the power and accuracy of our software.

Learn more about what makes our software different, and better

Yes, MaxiFi software works on most common tablets and phones and data entry is very easy on any device. However, because MaxiFi software presents detailed financial information, you may find that you have a better experience reviewing reports by using a tablet or larger device rather than a phone.

MaxiFi software is web based and works on Windows, Mac OS, or Linux using common web browsers such as Microsoft Edge, Chrome, Firefox, or Safari. We support the versions of these operating systems and browsers if they are currently supported by the companies or organizations that provide them. For Apple products this means we support a platform if they have released a normal release or security patch for the platform within the past 3 months.

The Maximized Plan in MaxiFi Planner includes the exact same accurate and comprehensive Social Security optimization we have in our Maximize My Social Security (MMSS) tool.

MaxiFi Planner offers the additional context of a full, lifetime financial plan so you can see, and adjust, the real impact on your lifetime living standard. For example, if postponing Social Security to maximize benefits means you will be short on income until Social Security kicks in at age 70, you can use MaxiFi Planner to create a comprehensive financial plan that will help "smooth" this living standard through the shortfall.

Both programs allow you to see the total lifetime maximized benefits compared to the "what-if" lifetime benefits of Social Security filing dates you specify. However, because MMSS is a more focused program, it provides a lengthier, more detailed comparison report showing all the Social Security benefit details side-by-side, whereas in MaxiFi Planner the Social Security report is one of many reports but still clearly shows the best SS benefit collection strategy. The detailed MMSS report also provides several pages of additional explanation about different Social Security benefits and the ins-and-outs of filing strategies.

The Professional version of MMSS provides two reports that are not found in MaxiFi Planner: a Longevity report allowing side-by-side comparison of different maximum ages and an Alternate Plans report that allows you to compare three different what-if scenarios side-by-side.

In short, if you don't want a comprehensive financial plan but just want to know your optimized Social Security filing strategy, MMSS may be all you need. If you want a comprehensive financial plan with Social Security (and other) optimizations, then MaxiFi Planner may be all you need. If you (or your clients) want the comprehensive financial plan and also detailed, focused reports comparing the Social Security benefits and strategies, you may want both tools.
