The Sinking Funds That Prevent Debt

Every "unexpected" expense is predictable if you look far enough ahead. Christmas happens every December. Car registration is due every year. Your phone will eventually break.

The reason these feel like emergencies is because most people don't save for them in advance. Sinking funds fix that.


What a sinking fund is

A sinking fund is a savings bucket for a specific future expense. You save a little every month so the expense doesn't hit your credit card when it arrives.

ExpenseAnnual costMonthly savings
Car insurance$1,200$100
Holiday gifts$600$50
Car maintenance$1,000$83
Annual subscriptions$300$25
Vacation$1,200$100

Five sinking funds. $358/month. No surprises. No debt.


Why it works

Most people budget for monthly expenses and ignore annual ones. When the annual expense arrives, they don't have the cash. So they borrow.

Sinking funds make the annual expense look like a monthly one. The money is already there when you need it.


How to set them up

  1. List predictable non-monthly expenses. Car registration, insurance, gifts, maintenance, travel, etc.
  2. Estimate the annual cost. Be realistic.
  3. Divide by 12. That's your monthly savings target.
  4. Open separate savings buckets. Many banks let you create sub-accounts for free.
  5. Auto-transfer on payday. Set it and forget it.

The honest read

A sinking fund is not an emergency fund. An emergency fund is for true surprises. A sinking fund is for predictable expenses you're pretending are surprises.

The difference between someone who stays in debt and someone who doesn't is often just this: one person saves for the predictable, and the other person borrows for it.
