FAQ
What is a sinking fund?
It is a pool of money you build a little at a time for one known future expense — holiday gifts, an annual insurance bill, or a car registration. You spread the cost into small monthly bites.
Why not just use a credit card?
A sinking fund means you pay cash and skip interest or debt stress. When the bill lands, the money is already waiting.
Can I run several sinking funds at once?
Yes. Add up the monthly amounts from each and transfer them together, or keep separate sub-accounts so you can see each goal.
