Lifestyle Guardrails
Which categories of spending are allowed to grow when income grows, and by how much. The Double Up Rule is the mechanism.
What it is
Lifestyle Guardrails are Financial Fellowship's method for deciding in advance which categories of spending are allowed to grow when a physician household's income grows, and by how much.
A guardrail is set per category, before the increase arrives, as a ceiling the household writes down while it is still thinking clearly. The comparison set is the problem. A physician's peer group is composed almost entirely of other high earners, which makes an objectively extraordinary income feel ordinary and makes lifestyle growth feel like catching up rather than spending. Guardrails get set before the comparison happens, because they cannot be set honestly after it.
How the guardrails work

Ceilings, written before the increase

The five categories that absorb the increase
Housing, transportation, travel, giving, and paid help. Those five absorb most of an income increase and four of the five are difficult to reverse once set.

The Double Up Rule
For every additional dollar the household allows itself to spend, an equal dollar goes to saving and investing. Spending is allowed to grow. It just has to bring a match. A household that wants to double its housing cost can, provided the savings side doubles with it, and if the savings side cannot double, the household has learned something specific about the purchase before making it.
Where it shows on the show
They apply before an income increase, which is the only moment they can be set honestly. After the increase arrives, the household is negotiating with itself.
They apply at the attending transition most of all, where a single step change in income meets a household that has been deferring purchases for a decade. They apply at every raise, bonus, partnership distribution, and new income stream after that.
They apply when a household notices it is spending because of what a colleague has. They apply before any purchase with a recurring cost attached. A house, a car, a club, a school, a second home. They also apply when a household feels guilty about spending it can genuinely afford. A guardrail gives permission as often as it withholds it.
Financial Health Assessment episodes built on Lifestyle Guardrails are listed here as they publish. Physician households can submit their own finances at financialfellowship.com/submit.
What it is not
They are not a budget, a restriction, or a judgment about anyone's spending. Financial Fellowship takes no position on what a household should want.
Not to be confused with retirement income "guardrails," the withdrawal rate framework associated with Jonathan Guyton and William Klinger. Lifestyle Guardrails govern spending growth during the earning years and are not a withdrawal strategy.

Common questions
What is the Double Up Rule?
For every additional dollar of spending a household allows itself, an equal dollar goes to saving and investing. Spending can grow as long as savings grows with it.
Are Lifestyle Guardrails a budget?
No. A budget tracks what was spent. Guardrails decide in advance what is allowed to grow, and they are set at the category level rather than line by line.
Do Lifestyle Guardrails mean I cannot upgrade my life?
No. They mean an upgrade brings a match. The framework exists to make spending sustainable rather than to prevent it.
Do Lifestyle Guardrails tell me how much to spend?
No. The household sets its own ceilings. The framework only asks that they get set in advance and in writing.
