How Sinking Funds Prevent Surprise Bills
Turn known future expenses into simple monthly contributions.
A sinking fund is money saved gradually for a cost you already know is coming. It is different from an emergency fund because the expense is expected.
List predictable irregular costs
Examples include annual insurance, vehicle servicing, birthdays, holidays, school costs and home maintenance.
Divide by the time remaining
A £1,200 annual bill due in 12 months requires £100 per month. If £300 is already saved, the remaining £900 requires £75 per month.
Keep each fund visible
Separate pots or clear labels reduce the risk of spending the money elsewhere.
Put it into practice
Use the connected calculator, save the result to your dashboard and review the figure during your next monthly check-in.
