Car maintenance and registration, holidays and birthdays, school costs, insurance paid annually, vet, travel, home repairs.
$600 holidays + $700 car + $300 registration/fees + $400 school = $2,000 a year = about $167 a month, set aside automatically.
One savings account with a note tracking each fund's share, or multiple named sub-accounts if your bank offers them.
December spending FROM the holiday fund is the plan succeeding. That's the entire point.
Car repairs and Decembers aren't surprises; they're appointments. Sinking funds just pay them in advance.
Why this beats 'we'll manage'
The most common debt relapse month becomes a normal month.
Tires are not emergencies when the car fund exists. The real fund stays whole for real shocks.
Irregular earners: sinking funds convert lumpy annual reality into one flat monthly number.

How is a sinking fund different from my emergency fund?
Direction of surprise. The emergency fund covers the genuinely unforeseeable: the layoff, the ER visit. Sinking funds cover the completely foreseeable that merely arrives in lumps: registration every March, gifts every December, brake pads eventually. Blending them is how emergency funds get 'raided' and how people conclude they can't save; the raid was really a budgeting gap wearing a crisis costume. Separate names, separate math, and both funds suddenly behave.
I can't fund every category. Which sinking funds come first?
Rank by wreckage-if-unfunded. Car repairs and insurance annuals first; their failure modes cascade into job trouble. Then the family-peace funds (holidays, school costs) whose failure lands on a credit card at 22%. Aspirational funds (travel, upgrades) join when income allows. Even $25 a month into a car fund converts the eventual $300 repair from card debt into an inconvenience. Partial funding is still armor.
