Sinking Fund Calculator

Figure out how much to save each month for a future expense, with or without interest.

What it means

About this calculator.

A sinking fund is just planned future spending

Car insurance, holidays, annual memberships, home repairs, and Christmas are not emergencies. A sinking fund turns predictable pain into smaller, boring transfers that barely register.

Deadline matters more than intensity

The same $1,200 goal feels easy over 12 months and brutal over 3. Testing the timeline is usually the fastest way to make a savings plan feel sane again.

FAQ

Questions people usually have.

Is a sinking fund the same as an emergency fund?

No. A sinking fund is for a known upcoming expense. An emergency fund is for unknown bad surprises like job loss, medical bills, or urgent repairs.

Should I keep a sinking fund invested?

Usually no if you need the money soon. For shorter timelines, most people keep sinking funds in cash or a high-yield savings account so market swings do not wreck the deadline.
