When to use it

Use it when irregular but predictable costs keep upsetting your budget.

How to apply it
  1. List expenses you know are coming in the next year.
  2. Estimate the cost and due date of each.
  3. Divide each cost by the months remaining to get a monthly amount.
  4. Set aside those amounts each month, in separate pots if possible.
  5. Spend from the relevant pot when the expense arrives.
Tip: Keep sinking funds separate from your emergency fund so planned costs do not drain it.
