Personal Finance Basics

What is Sinking Fund?

A sinking fund is money set aside regularly to pay off a debt or replace a large asset. It’s a way to spread a big future cost over time. This protects bondholders by systematically reducing default risk. In personal finance, the term is adapted to describe a targeted savings reserve established to pay for a known, future expense that does not occur monthly, such as a annual property tax bill, holiday travel, or home maintenance, preventing budget disruption.

Sinking funds differ from emergency funds; while emergency funds are reserved for unexpected crises, sinking funds are planned savings pools for expected, non-recurring obligations.

PRACTICAL EXAMPLE
