A sinking fund is money you set aside, a little at a time, for something you know is coming.
Christmas. Car repairs. That annual subscription that ambushes you every March. Instead of panicking when the bill arrives, you save toward it month by month - so when it comes, the money is simply…there.
How it works
- List the big irregular expenses coming in the next 12 months
- Divide each one by the number of months until it's due
- Set that amount aside every month - its own envelope, its own little fund
- When the bill arrives, pay from the fund. No stress, no credit card.
Example: Christmas will cost about $600 and it's July. $600 ÷ 6 months = $100 a month. By December, you're shopping with cash you already saved - and January-you says thank you.
Why "sinking"?
It's an old accounting term for money gradually "sinking" into a fund. We like to think of it differently: you're planting seeds, month by month, and harvesting peace of mind.
Sinking funds vs. Emergency fund
Your emergency fund is for surprises. Sinking funds are for certainties. Both matter, but only one of them ruins Christmas.
