What It Means
A sinking fundSinking fundMoney set aside in small, regular amounts for a known future cost, so the bill doesn't land on a single paycheck. See more and an emergency fundEmergency fundMoney set aside only for unplanned costs, like a car repair, a medical bill or a lost paycheck, kept where you can reach it quickly. See more are both savings set aside ahead of time, for different kinds of costs. A sinking fund builds up on a schedule for an expense you can see coming, such as an insurance renewal, holiday gifts or car maintenance, and it's meant to be spent when that bill arrives. An emergency fund is kept for costs you can't predict, such as a job loss, a medical bill or an urgent repair, so you don't have to borrow when one hits. Experian advises keeping the two apart, so planned spending never drains the money meant for a crisis.

The Breakdown
Side by side
| Sinking fund | Emergency fund | |
|---|---|---|
| What it's for | Costs you can put on a calendar | Costs you can't predict |
| Examples | Insurance renewals, holiday gifts, school costs, regular car and home upkeep | Job loss, medical billsMedical debtMoney owed for health care, such as hospital, doctor, lab or ambulance bills; unpaid bills can go to collections and, in some cases, onto credit reports. See more, urgent car or home repairs |
| How to size it | Each cost divided by the months until it's due | Months of essential expenses |
| Spending it | Expected, then it builds again for next time | Only in a real emergency, then refilled |
Worked example. A household with $3,200 a month of essential costs sets targets for both:
| Fund | Target | Set aside each month |
|---|---|---|
| Emergency fund (3 months of essentials) | $9,600 | $300 until it's reached |
| Car insurance renewal in 8 months | $1,200 | $150 |
| Holiday gifts in 1010,000 stepsA popular daily step goal that began as the name of a 1960s Japanese pedometer; later studies find health benefits begin well below it. See more months | $600 | $60 |
| School costs in 6 months | $300 | $50 |
The three sinking funds need $260 a month on a fixed schedule, and the emergency fund takes whatever the budgetBudgetA plan for a set period, usually a month, that lists the money you expect to receive and how you'll spend or save it. See more can spare, here $300.
Pick the sinking fund if you know roughly how much a cost will be and when it's due. Pick the emergency fund if the cost is sudden, can't wait and couldn't have been planned.
Good to Know
Experian recommends keeping emergency savings and sinking funds separate, since a sinking fund is meant to be spent while the emergency fund stays whole for a crisis. For sizing the emergency fund, the FDIC says financial experts generally recommend at least six months of living expenses in a federally insured product, and the Consumer Financial Protection Bureau says the right amount depends on your situation, adding that even a small balance helps. A small emergency fund first keeps a surprise off a credit card, and sinking funds for the costs that squeezed you last year can follow or grow alongside it.
FAQ
What's the difference between a sinking fund and an emergency fund?
A sinking fund saves for planned costs with a known amount and date, and it gets spent when they arrive. An emergency fund covers unexpected costs, like a job loss or an urgent repair, and is left alone otherwise.
Should I build an emergency fund or sinking funds first?
A small emergency fund first means a surprise doesn't have to go on a credit card. Sinking funds for the known costs that caused a squeeze before can follow, and both can grow at the same time once the budget allows.
Can I keep a sinking fund and an emergency fund in the same account?
You can if you track each balance separately, though Experian suggests keeping them apart so planned spending doesn't eat into emergency money. Some banks let you split one savings accountSavings accountA bank or credit union account for money you're setting aside for later, which earns interest and is insured up to federal limits at insured institutions.
