Sinking funds: how to stop being surprised by known costs

Car registration, holidays, insurance premiums — predictable costs deserve their own plan.

A sinking fund is money you set aside monthly for a cost you know is coming but that doesn't happen monthly.

How to build one

  1. Write down the expense and the total amount — for example, $1,200 for holiday gifts.
  2. Divide by the number of months until you need it — $100 a month for 12 months.
  3. Treat that number like a bill in your budget.
  • Common sinking funds: car maintenance, annual insurance, travel, gifts, property tax, pet care, home repairs.
  • You can keep them all in one savings account as long as you track the target amounts separately.
