Sinking Funds: The Simple Trick for a Budget That Never Breaks

2026-07-07

Ever get blindsided by a "surprise" expense that wasn't really a surprise — car registration, holidays, insurance? Sinking funds are the fix. They're the simplest trick for a budget that never breaks.

What is a sinking fund?

A sinking fund is money you set aside a little at a time for a known future expense. Christmas costs $600? Save $50/month starting in January and it's fully funded — no December panic, no credit card. You "sink" small amounts so the big bill is already paid for.

Common sinking funds

Track each fund separately so you always know what's covered. A Sinking Funds Tracker keeps every fund and its target in one place.
