Some costs are predictable but not monthly: annual insurance, holidays, car repairs, school fees. A sinking fund stops them from feeling like emergencies.
Direct answer
A sinking fund is a pot of money you build in small regular amounts for a known future expense. You divide the cost by the months until it is due and save that amount each month. When the bill arrives, the money is already there.
How to work out the amount
Monthly amount = total cost ÷ months until due. A 600 annual bill due in 12 months needs 50 a month. If you only have 6 months, it needs 100 a month.
What to save for
- Annual or six-monthly insurance and subscriptions
- Car maintenance and tyres
- Gifts and holidays
- Medical and dental costs
- Back-to-school or term fees
- Home repairs and replacing appliances
Where to keep it
Use a separate savings account or a clearly labelled pot so you do not spend it by accident. Many banks let you create several named pots.
Sinking fund vs emergency fund
Keep them apart. The emergency fund covers the unexpected. Sinking funds cover the expected-but-irregular. Mixing them makes it hard to tell whether you are really covered.
