Happy Saturday,

Here is this week’s edition of 6-Point Saturday — financial insights to help you make smarter money decisions.

Entrepreneur and author Derek Sivers founded and eventually sold his company CD Baby for $22 million. On the Tim Ferriss show, Sivers explained a simple rule of thumb to help make better decisions:

One of the things I like about Sivers' rule is that it builds a margin of safety into your decisions. When the threshold is "hell yeah or no," the merely good opportunities get filtered out automatically, leaving room for the great.

Rules like this are called heuristics. Simple decision filters. And in the right context, they can be incredibly powerful tools.

For instance, forecasting exactly how you'll want to spend retirement 20 or 30 years from now is pretty difficult. You don't know what your life will look like. Plugging multiple, complex assumptions into a spreadsheet can give you the illusion of precision.

A rough rule like saving 15% or more of your gross income sidesteps all of that. You don't need to know exactly what you'll want in 30 years. You just need to give your future self enough options so that you’ll be able to act when you do know.

That's the advantage of using heuristics. They beat overwhelm. They build momentum. They get you 80% of the way there without all of the complexity. And for someone who's been staring at their finances without making a move, they create urgency. A simple rule gives you something to act on today.

Like most things, heuristics come with tradeoffs. They’re not perfect, but they're not designed to be. Heuristics can run on many assumptions. Assumptions that may not exactly fit your situation. For example, if you’ve been diligently saving for years, you may not need to target 15% of your gross income.

The purpose of heuristics is what I like to call “Great Enough” progress: they produce excellent choices today that you can optimize tomorrow.

So let's look at a few heuristics you can put to work in your finances right now.

The 50/30/20 spending plan places your take-home pay into three buckets: 50% to fixed costs, 30% to lifestyle spending, and 20% to savings and investing (more on investing in Point #4). It doesn’t fit every situation perfectly (for example, if you live in a high cost of living area, your fixed may be more and lifestyle a bit less), but it gives you a quick starting framework.

Build three to six months of essential expenses in cash, kept somewhere like a high-yield savings account. If you're carrying high-interest debt right now, start smaller. A couple thousand dollars creates a cushion that keeps one bad month from derailing everything. Get that in place first, then attack your debt.

Two approaches you can use here. The avalanche approach pays off your highest interest rate debt first, saving the most money over time. The snowball pays off your smallest balance first, building momentum through quick wins. The rule for how to pick? Simply pick the one that sounds most attractive to you right now (if you’re indecisive, choose snowball to start).

If you want a single, sensible default for your retirement account, target date funds fit the bill. These funds automatically adjust your allocation to stocks and bonds over time, based on your targeted retirement year. As always, be sure to check the expense ratio. The industry average has continued to drop over the years to around .27% in 2025.

Three rules of thumb worth knowing before you buy. Put 20% down, to avoid private mortgage insurance. Plan to stay at least seven to ten years, so the transaction costs are worth it. And budget roughly 1% of the home's value per year for maintenance. On a $400,000 home, that's $4,000 annually, or around $330/month. Many first-time buyers underestimate this one.

Which one of these heuristics would improve your finances the most? Consider taking one concrete step toward it this week.

This individual is certainly not alone. Every day brings new headlines and data: inflation, interest rates, wars, tariffs...the list can feel endless. The news cycle is engineered to generate fear and urgency.

And when you're already struggling with figuring out your finances, that noise can make an already challenging problem feel impossible.

The solution isn't to become a better consumer of financial news. It’s to separate what’s inside your control and what’s not. And simplify your decision-making with helpful heuristics.

You cannot control inflation. You cannot control interest rates. You cannot control what the Fed decides to do at its next meeting.

Spending mental energy trying to decipher all of that is exhausting and mostly a distraction.

What you can control is your personal economy. Your income. Your spending. Your savings rate. Your debt. These are the levers that actually move the needle on your financial life.

This is exactly where heuristics add a lot of value. You don't need a PhD in economics to build real financial strength. You need a few simple rules (like the ones in Point #2 above), applied consistently, to the things within your control.

Retirement planning is pretty complex. You need assumptions about inflation, investment returns, wage growth, Social Security claiming age, life expectancy, healthcare costs, and your spending in retirement.

Understanding the assumptions behind retirement Monte Carlo simulations and other approaches is another challenge. There is real reason to question whether many people want to take the time to meaningfully understand their results—and feel confident about them.

The good news? Research actually supports leaning on simple rules in exactly these kinds of uncertain environments.

When the variables are too many and the future too unpredictable, well-designed heuristics can outperform complex models. Not because they're more accurate, but because they're actionable and understandable.

A rule you can understand and apply beats “sophisticated” projections that leave you uncertain and overwhelmed.

A recent study published in the Journal of Financial Planning put this to the test. Researchers from Texas Tech University and the University of Wisconsin used data from 3,227 households in the Federal Reserve's 2022 Survey of Consumer Finances to ask whether a single ratio, savings divided by income, tracked with how people actually feel about their retirement readiness.

The results show it does. Households whose savings met the benchmark were nearly 10 percentage points more likely to report feeling very satisfied about their expected retirement income, and nearly 9 percentage points less likely to report feeling totally inadequate. A meaningful signal from a single number.

The benchmark they tested comes from Fidelity's published savings milestones:

To check your own progress, divide your retirement savings by your household income. That's your savings-to-income multiple. Compare it to the milestone for your age.

As always with heuristics, you need to check the assumptions baked into these benchmarks. For instance, Fidelity assumes retirement at 67, a 15% ongoing savings rate, Social Security claimed at 67, and a retirement income replacement rate of roughly 45% of pre-retirement income. There’s also no pension income factored in. So, if your situation looks meaningfully different, your number may need adjusting.

But for someone decades from retirement, this gives you something many people don't have: a simple and quick initial read on where your retirement savings stand.
