Kitces: The faults of a popular retirement saving tool

Saving and accumulating for retirement takes decades so it can be hard for clients to stay motivated toward long-term goals. Further muddling the picture is that a balance on its own gives no context to where it stands relative to the retirement goal itself. It’s just a number.

However, an increasingly popular strategy for tracking a saver’s progress is the funded ratio — where the current account value is presented as a percentage of the total savings necessary to achieve the retirement goal. Even the funded ratio has its problems, though, not least of them being its high volatility to market movements — i.e., the very forces that can impact a saver’s resolve.

Still, benchmarking portfolios against the goals they’re meant to achieve is a worthwhile activity, warts and all, and we should only expect to see this ratio approach increase its footprint.

HOW TO CALCULATE
In the simplest case, the ratio is represented as simply a fraction, where the numerator is the current value of assets and the denominator is the goal to be reached. As progress is made toward the goal, the funded ratio rises. When the ratio reaches 100%, the goal has been achieved — or at least, is fully on track to be achieved.

Example 1. Eric and Jennifer have a retirement goal of accumulating $1 million in savings, which on top of Social Security will allow them to realize their desired standard of living in retirement. The couple currently has about $350,000 in their retirement accounts. As a result, their funded ratio is $350,000 / $1 million = 35%.

As the couple makes ongoing contributions and watches the account balance increase, the funded ratio will rise. In fact, even if no contributions are made, this funded ratio should still rise over time, simply given the growth in the portfolio itself.

The virtue of this approach is that instead of talking in terms of abstract dollars — which doesn’t directly relate to a goal — the funded ratio gives a concrete sense of progress. This is particularly valuable because in practice, most people’s goals – or at least, the required account balance to fund those goals – aren’t so conducive to calculating progress. Indeed, while it might be relatively straightforward to figure out that $350,000 out of a $1 million goal is 35% progress, if the retirement goal is actually $1.35 million, determining that it takes about $475,000 to get to the same 35% funded ratio takes a little more work.

In addition, the funded ratio also helps put market volatility into context. It moves away from just looking at the dollar magnitude of a bear market decline or the percentage drawdown, and instead relates it back directly to the goal.

Example 2. If next year there’s a 20% bear market, Eric and Jennifer’s account balance would fall to $280,000. If they were each contributing the maximum $18,000 limit for the 2017 tax year, it may feel very scary to lose $70,000 when they’re only able to save $36,000/year. However, as a funded ratio, the couple has merely fallen from being 35% funded to 28% funded, which may feel far less daunting of a setback to recover from.

Unfortunately though, there’s a significant problem with the straightforward approach of calculating a retirement goal’s funded ratio by simply dividing current assets into the goal: The path of progress to the goal doesn’t follow a straight line.

Imagine someone who wants to accumulate $1 million for retirement in 40 years. Assuming an 8% return on a fairly aggressive portfolio — given the 40-year time horizon — the individual would have to save about $300/month to achieve the goal. Even though the cumulative savings over the 40-year time period will be only $144,000, this works because of the magic of compounding growth over an extended period of time.

The caveat is that it takes quite a while for the compounding to really begin to work its magic. As a result, while $300/month at 8% is sufficient to fully fund 100% of a $1 million retirement savings goal in 40 years, it takes a whopping 23 years just to fund the first 25%. Then it takes about eight more years to fund the next 25%. From there, compounding really kicks in, and it takes only five years to cover the third 25%, and a mere three to achieve the last 25%.

In other words, the problem with just looking at the progress of savings toward a retirement goal is that in the early years, the contributions alone have to do the heavy lifting. It’s only in later years that the compounding really kicks in to carry through to the end. This ironically means that someone who is 100% on track for the 40-year goal will still not even be halfway there after 30 years!

Yet most people won’t realize that being 50% of the way to the 40-year goal after 30 years actually is a reflection of being on track, and there’s nothing in a funded ratio that communicates this is a normal way to progress toward retirement. In fact, having such a long-term goal that makes so little progress for decades can actually become demotivating for retirement saving.

The fundamental challenge to the simple retirement goal funded ratio is that it fails to account for the anticipation of future growth, and how much time is available for that growth to occur.

In the context of pension plans — where the funded ratio originated as a way to calculate whether the pension account had sufficient assets to cover its future liabilities — this is resolved by adjusting the denominator of the funded ratio. Instead of simply inputting the goal, the bottom half of the funded ratio represents the present value of any/all future liabilities — where the liabilities are the cash flows that the goal represents.

The virtue of calculating a funded ratio using not just the goal, but the present value of the goal, is that doing so implicitly recognizes that if the money isn’t actually needed until the future, it will have time to grow until it’s used. This means it’s actually possible to be on track for 100% funding, even though 100% of the goal isn’t currently funded, because there’s enough to grow to the goal by the time the end date — i.e., retirement — is reached.

Continuing the earlier example: A couple that has accumulated $250,000 already after 20 years, and is still saving $300/month toward retirement and is still growing at 8%, may only be 25% of the way to the goal, but would actually have 123% of the funding needed to reach a $1 million goal in 20 years. In other words, the present value of a $1 million goal 20 years from now is only $202,971 — assuming that 8% growth rate compounded monthly. This means that already having $250,000, and still saving $300/month on top, is more than enough to be on track for the goal.

The key distinction: A funded ratio that adjusts for the time value of money is no longer actually calculating the progress toward the goal per se, but instead is determining whether the individual is on track for the goal given future growth assumptions.

ABSOLUTE RETURN
The challenge to calculating the funded ratio as a present value of future liabilities is that it’s highly sensitive to the discount rate — i.e., the assumed future growth rate — that is used. As a result, a retirement projection can show itself as being on track, materially underfunded or dramatically overfunded simply by changing the long-term growth rate assumptions.

Kitces-sensitivity of funded ratios future growth rate assumptions

As the chart above illustrates, if the client sticks with the original goal of an 8% return and $300/month savings, the goal is still fully funded in the end. But lower growth assumptions make it appear as though they aren’t saving enough, only to get surprised by good returns later. Meanwhile, the higher growth assumptions make it appear as though they are saving too much, only to find that later returns disappoint and they’re not over-funded after all.

These kinds of assumption changes can be dangerous. If the prospective retiree continues to assume 8% returns but gets only 7%, retirement appears to be on track early on — until it falters in the middle and loses momentum, never actually closing the gap despite the saver continuing to save and the portfolio continuing to grow.

Unfortunately, as the chart above illustrates, if growth rate assumptions are overly optimistic, that makes the funded ratio seem to make early progress — right up until it doesn’t, and it turns out that the retirement date is no longer feasible after all, as the shortfall gap never closes.

In fact, a substantial challenge of the whole approach is that the higher the growth rate, the easier it is to make the funded ratio look good, but the riskier it actually is to hit that retirement date, given the volatility that higher growth rates entail — which isn’t captured in a funded ratio.

In other words, calculating a funded ratio that is the present value of future liabilities at a specified discount code is basically the equivalent of creating an absolute return benchmark out of that discount rate, and any year the actual portfolio — plus new contributions — underperforms, the funded ratio will decline.

From the perspective of managing retiree expectations, this can be a substantial issue. After all, it’s long been observed among advisors that in a bear market, clients tend to benchmark results to cash — that is, maintaining principal and not losing any money. But with a funded ratio approach, the situation is even worse, as the portfolio is now effectively benchmarked to a straight-line 7% or some other absolute return.

Thus, over time as the impact of growth and compounding increasingly control the outcome, the funded ratio basically becomes an on-track for absolute return benchmark ratio. And with real-world volatility, this can actually cause an astonishing level of volatility in the funded ratio itself.

For instance, the chart below shows the funded ratio progress for someone who in 1997 was hoping to retire in 2017, and at the time had $180,000. This would indicate being 75% funded for a retirement goal of $1 million in 2017, as long as they kept saving at least $300/month and grew at 8% on a balanced portfolio — which, at the time, would have been a relatively conservative assumption for growth on a balanced portfolio. Yet we can see what actually happened to their progress on a 60/40 portfolio based on the funded ratio.

Kitces-High volatility of funded ratio over time

As the chart reveals, the run-up in the markets quickly led this saver to be overfunded on a PV-based funded ratio, suggesting they could even stop saving by 1999 — only to fall behind again with the subsequent bear market, and then never actually close the gap even when the saving continued. While the contributions-based funded ratio showed steady progress, that still never quite achieved the goal.

Stated more simply, the saver’s progress on the funded ratio was never actually a particularly effective indicator of whether they were on track, and because markets are so volatile, any changes to savings behavior to try to adjust for “fundedness” would have likely just ended out over-compensating for volatility in each direction. Ultimately, the funded ratio ended out reflecting nothing more than whether the saver was on track for achieving an annual absolute-return portfolio goal, which obviously isn’t realistic.

A VIABLE ALTERNATIVE?
Given these challenges to the funded ratio, is there a viable alternative? Unfortunately, the alternatives — such as the traditional approach of simply displaying account balances and how they’re growing over time — clearly have their own problems, as all advisors experience from day to day and year to year in counseling clients through market volatility.

That said, there are some creative new proposals lately, such as converting retirement accounts into future retirement income, to give people a better sense of how their retirement account progress translates into an actual future standard of living.

Notwithstanding the challenges, it’s worth noting that the approach does have some significant positives.

First and foremost, it does help people get away from being overly focused on dollars and account balances. As noted earlier, a person with 10 years remaining to retirement should have less than half their retirement account balance if they’re on track, and may feel very far behind just looking at their account balance alone. And yet, they can see they may actually be 100% on track with a funded ratio — at least, one that accounts for the time value of money.

Second, the funded ratio can help to automatically recognize when changes in standard of living are shifting the progress toward the goal. For instance, people who get raises but also lift their expenses and experience lifestyle creep can start to veer further and further off track even though their account balance is rising. That’s because their retirement needs are actually rising even faster than their retirement accounts.

Unfortunately, this is not evident if the prospective retiree is just watching the account balance grow. But it will be noticeable if retirement progress is tracking using a funded ratio, where the amount needed to be fully funded keeps going up, given that the higher spending creates a larger liability to sustain that future spending.

Still, the challenge remains that a goal-based funded ratio isn’t really any different than just showing an account balance and how it’s tracking relative to the goal, and a true discounted-present-value funded ratio can quickly become an absolute return benchmark taskmaster that, once falling behind, gets harder and harder to catch up on.

Of course, it’s always possible to update and adjust a goal as well if the funded ratio is persistently off track. And individuals at least have more flexibility to adjust their goals, unlike many pension plans that had unrealistically high return assumptions to calculate their funded ratios, and the mediocre returns since 2000 have caused them to just lag and lag more and more.

However, at the point that the funded ratio just gets changed every few years with a plan update that alters the final goal, it’s not entirely clear how useful of a tracking mechanism it even is. After all, for those who still have a long time horizon, changes to the funded ratio assumptions — from future spending needs to the growth rate — may change the funded ratio even more than the actual saving and investment results.

There are actually a lot of potential assumptions underlying the funded ratio, including not only the time horizon to retirement and the growth rate, but in a true calculation of the present value of all future liabilities — i.e., every future retirement cash flow — the assumptions would/could also include mortality rates and/or the retirement time horizon and even age-banded changes in retirement spending needs over time. Not to mention that a truly accurate reflection of all potential assets to fund future liabilities would likely need to include valuing illiquid Social Security and pension income streams as well.

This all means that in the end, the funded ratio may just be another tool in the shed. After all, some indicator of whether the client is on track toward goals is almost certainly useful, but it’s still not clear that it is really all that much better as a key performance indicator for retirement progress. Over time, it’s almost entirely dependent on uncontrollable returns, yet fails to express that range of possibilities.

By contrast, at least a regularly updated Monte Carlo analysis conveys both the progress toward goals, and the fact that there’s still a range of possible outcomes going forward — explicitly recognizing that even a plan that’s on track won’t necessarily stay on track. Nonetheless, the rising capabilities of planning software to continuously track and update the status of a plan means a more nuanced form of progress-tracking toward goals seems likely to emerge in the coming years.

So what do you think? Are there problems with using a funded ratio to track progress towards retirement? Do you use a funded ratio with your clients? What adjustments can be made to improve a funded ratio? Please share your thoughts in the comments.
