Frequently asked questions

What is a sinking fund, exactly?

It is savings earmarked for one specific, planned expense, kept separate from your general savings or emergency fund. Because the goal and the amount are both defined in advance, a sinking fund turns a large future cost into a small, predictable monthly habit.

How is a sinking fund different from an emergency fund?

An emergency fund covers the unexpected, a job loss, a medical bill, and stays untouched otherwise. A sinking fund covers the expected but irregular, a vacation, a new appliance, a holiday season, something you know is coming and can plan for in advance.

What if I already have some money saved toward this goal?

Enter it, the calculator subtracts what you already have from the total needed and spreads only the remaining amount across the months left until your target date, so the monthly number reflects real progress, not the full cost from scratch.

Can I track more than one sinking fund at a time?

Yes, add as many goals as you have, each with its own target amount, date, and progress. Seeing them side by side makes it easier to prioritize which one gets funded first when money is tight in a given month.

What are common things people use sinking funds for?

Holiday spending, car maintenance or replacement, annual insurance premiums, vacations, home repairs, and wedding costs are some of the most common. Anything with a known rough cost and a rough timeline is a good candidate for its own sinking fund.
