The Best Decision Isn’t Always the Highest-Return Decision
The spreadsheet can tell you what a decision costs financially. It can’t tell you what it costs you to carry it.
We have gotten very good at pretending every important decision can be solved by a spreadsheet.
Highest return.
Lowest cost.
Best rate.
Maximum efficiency.
Useful.
Sometimes necessary.
Still incomplete.
Someone I work with came into a significant
amount of money and started working through what to do with it.
Retirement account.
Brokerage account.
Debt.
Keep some liquid.
The math points in different directions depending on taxes, interest rates, time horizon, access to the money.
Then we got to the debt.
On paper, if the loan is cheap and the expected investment return is higher, paying it off early may be the inferior move.
And they said something simple:
paying it off would make me feel good because it would be done
That matters.
Not more than math.
But it matters.
We get strange about this because once a decision has a number attached to it, everything else starts looking irrational.
If the expected return is 10% and the loan costs 5%, obviously invest.
Case closed.
Except you are not a spreadsheet.
You have attention.
Stress.
Memory.
Risk tolerance.
Sleep.
Relationships.
A nervous system.
You carry unfinished things differently than the person next to you.
There are people who can hold cheap debt for thirty years and never think about it.
There are people who will think about it every week.
Those two people are not making the same trade even if the interest rate is identical.
The math is the same.
The cost is not.
I want to be careful because “peace of mind” can become a very expensive phrase.
People use emotion to defend terrible decisions all the time.
They sell investments during a panic.
They finance things they cannot afford because the payment feels manageable.
They pay off low-cost debt while ignoring a financial emergency somewhere else.
Feelings are not exempt from scrutiny because they are feelings.
But neither is the math.
A mathematically optimal decision that creates enough psychological drag can become worse in practice than the slightly less efficient decision you can actually live with.
That is true outside money too.
The highest-paying job may not be the best job.
The cheapest living arrangement may not be the least costly.
The fastest route may demand a version of your life you do not want to inhabit.
The issue is not choosing feelings over logic.
It is refusing to define logic so narrowly that the human being making the decision disappears from the calculation.
Run the numbers.
Know what you are giving up.
Then ask the question spreadsheets cannot answer for you:
What does this choice cost me to carry?
Sometimes the higher-return decision still wins.
Sometimes it does not.
You are allowed to include yourself in the math.
