Cash at home is useful when the power is out, the card reader is down, or you need money fast. It’s also one of the riskiest things to keep in a house. Theft is part of it, but cash is also paper, and insurance covers very little of it.
This guide covers how to decide how much to keep, what your policy really pays, how to protect bills from fire and water, and what the U.S. Treasury will do if your cash gets burned, soaked, or chewed.
How much cash should you keep at home?
No official rule sets a dollar amount, but government guidance points in one direction: a small amount.
- Ready.gov (FEMA) advises keeping “a small amount of cash at home in a safe place,” and stresses small bills, because ATMs and credit cards may not work during a disaster.
- Money in the bank is insured. Cash at home isn’t. The FDIC insures deposits up to $250,000 per depositor, per ownership category, at each insured bank. The FDIC also lists safe deposit boxes and their contents as not covered. Our home safe vs. safe deposit box guide covers the trade-offs.
A practical way to size it:
- Estimate a few days of essentials you might need to pay for in cash during an outage, like fuel, groceries, and medications.
- Compare it with your policy’s money limit (next section). Anything above that limit is uninsured.
- Keep the rest in an insured account, unless you have a specific reason not to.
What to look for: a small fire- and water-resistant cash and document box.

What insurance actually pays for cash
Standard homeowners policies have special limits for money. In the sample HO-3 policy form published by the Insurance Information Institute, Coverage C limits “money, bank notes, bullion, gold… coins, medals, scrip, stored value cards” to $200 per loss. That limit is the total for the whole category, not per bill or per drawer.
Your policy may differ, so read its special limits section and ask your agent:
- What is the limit for money, and does it apply to every cause of loss?
- Can the limit be raised by endorsement, and at what cost?
- What proof would you need for a cash claim?
Our home inventory guide explains how to read special limits for other valuables and document what you own. For cash, the takeaway is simple: assume most of it is uninsured, and store it accordingly.
Fire: cash is paper
U.S. currency is made of 75% cotton and 25% linen, according to the Bureau of Engraving and Printing (BEP). It’s tougher than printer paper, but it still burns and chars.
What that means for storage:
- Treat cash like documents. A safe with an independent fire rating for paper, such as UL Class 350, is designed to keep its interior below the temperature where paper chars. Our fire safe vs. burglary safe guide explains the ratings.
- A burglary-only safe may not protect cash in a fire. A thick steel box without fire insulation can get very hot inside.
- Fire bags aren’t a substitute. A bag’s temperature rating usually describes the fabric, not the inside, and independent flame tests found bags couldn’t keep documents intact under sustained heat. See fireproof document bags vs. fire safes.
Water: floods, hoses, and humidity
Water is the quieter risk. Firefighting, burst pipes, and floods can soak a safe that survived the heat.
- Look for a separate water rating. A fire rating says nothing about water. Our document protection guide explains independent water ratings and why a sealed inner bag helps.
- Bag it anyway. A resealable waterproof pouch inside the safe adds a cheap second layer.
- Watch humidity. Sealed fire safes can trap moisture. Our safe humidity guide covers desiccants and hygrometers.
What to look for: a waterproof zip pouch sized for currency and a UL Class 350 fire safe with an independent water rating.

Theft: make cash hard to find and hard to carry off
In the burglar interviews and police guidance covered in our hiding-spots guide, cash ranks among the first things thieves look for. The basics:
- Anchor the safe. A small safe that isn’t bolted down can be carried out. See how to anchor a safe to the floor.
- Choose the location carefully. Our safe placement guide covers where burglars tend to look first.
- Keep hiding spots for small amounts only. A diversion safe has no fire or water protection. Our diversion safes and hiding spots guide covers what works.
- Tell one trusted person. Cash no one knows about can be lost forever if something happens to you.
If your cash is damaged: what the Treasury will replace
Damaged money isn’t always lost. What to do depends on how bad the damage is.
Lightly damaged (“unfit”) bills: go to your bank
The BEP says currency that’s dirty, defaced, limp, torn, or worn is “unfit,” not mutilated. It shouldn’t be sent to the BEP and may be exchanged at commercial financial institutions. Ask your bank.
Mutilated bills: the BEP Mutilated Currency Division
The BEP defines mutilated currency as currency where half or less of the original note remains, or its condition makes its value questionable. It lists fire, water, chemicals, explosives, animal or insect damage, and deterioration from burying as the most common causes.
The BEP says it may redeem a note at full value when:
- Clearly more than 50% of a note identifiable as U.S. currency is present, along with enough of any relevant security feature, or
- 50% or less is present, and the method of mutilation and supporting evidence satisfy the BEP that the missing portions were totally destroyed.
It won’t redeem submissions that show intentional mutilation, fraud, or criminal activity, contain material misrepresentations, or can’t be identified as U.S. currency.
How to pack it. BEP’s packing directions (also in federal regulations, 31 CFR 100.8) say:
- Disturb the fragments as little as possible.
- If notes are brittle, pack them carefully in cotton and box them as found.
- If the money was damaged inside a purse, box, or other container, leave it in the container if you can. If you have to remove it, send the container too.
- Don’t roll, fold, laminate, tape, or glue flat notes. Don’t unroll notes that were in a roll.
- Remove any coins or metal, which can break up the paper. Damaged coins go to the U.S. Mint instead.
How to submit. Every submission needs a completed, signed BEP Form 5283. The BEP’s instructions encourage sending it by USPS registered or certified mail, and in-person drop-offs are accepted only in Washington, D.C. Claims of $500 or more are paid electronically to a U.S. bank account.
What to expect. The service is free. The BEP says standard requests generally take six to 36 months, depending on the condition of the notes. It receives more than 22,000 requests a year.
Tip: if a fire or flood damages your stash, photograph it before you move anything. That helps both the BEP submission and any insurance claim.
If you deposit a large amount later
If you’ve built up a large cash reserve and decide to deposit it, know the rules first. The Financial Crimes Enforcement Network (FinCEN) explains that banks must report cash transactions over $10,000 on a Currency Transaction Report, including multiple transactions that add up to more than $10,000 in a day. Handling large amounts of cash isn’t illegal. But splitting deposits to avoid the report is a federal crime called “structuring,” even when the money itself is legitimate. Deposit it normally and keep records of where it came from.
Quick checklist
- A small amount on hand, mostly in small bills
- The total compared with your policy’s money limit
- Stored in a safe with an independent paper fire rating, anchored down
- Inside a waterproof pouch, with humidity checked
- Hiding spots used only for small amounts
- One trusted person knows where it is
- Damaged bills: bank for “unfit,” BEP Form 5283 for mutilated, packed as found
Bottom line
Keep enough cash for a short disruption, in small bills, and assume insurance won’t cover much of it. Store it like the paper it is: in an anchored safe with a real fire rating, sealed against water. If disaster strikes anyway, don’t throw out burned or soaked money. Pack it as found and send it to the BEP.
