Security Deposit Calculator

A security deposit protects a landlord against unpaid rent and damage beyond normal wear and tear — but it is the tenant's money, held in trust and refundable. This calculator helps you understand deposit limits, what can be deducted, and what you should get back when you move out.

Deposit limits and your rights

How much a landlord may collect is governed by state and sometimes local law. Many states cap deposits at one or two months' rent, and some require the money to be held in a separate, sometimes interest-bearing, account with the interest owed to the tenant. A number of jurisdictions also require landlords to return the deposit within a set window — often 14 to 30 days after move-out — along with an itemized statement of any deductions.

Because these rules vary widely, it pays to know your local statute before signing or disputing. Where a landlord fails to follow the required timeline or documentation, many states impose penalties of two to three times the deposit, giving tenants real leverage. This calculator is a general guide; always confirm the specific limits and deadlines that apply where you rent.

Normal wear vs. chargeable damage

The central dispute in most deposit cases is the line between ordinary wear and tenant-caused damage. Faded paint, minor carpet wear, small nail holes, and general aging are normal wear that landlords are expected to absorb as a cost of doing business. Broken fixtures, large holes, pet stains, and unauthorized alterations are damage that can legitimately be deducted.

Documentation is your best protection. Photograph or video the unit thoroughly at move-in and move-out, keep a copy of any move-in condition checklist, and put requests and complaints in writing. When it is time to move out, cleaning the unit and repairing minor issues yourself is almost always cheaper than the rates a landlord will charge against your deposit.

Frequently Asked Questions

Can a landlord charge more than the legal maximum?+

No — charging above the legal limit is a violation of tenant protection laws. In many states, overcharging entitles the tenant to damages of double or triple the excess amount.

When must a security deposit be returned?+

Most states require return within 14–30 days after move-out, along with an itemized list of any deductions. Failure to return on time can result in the landlord forfeiting the right to deductions and owing penalties.

Can a security deposit be used for last month's rent?+

Technically no — security deposits must only be used for unpaid rent or damages beyond normal wear and tear. However, many landlords and tenants informally agree to apply the deposit to last month's rent.

Is a pet deposit different from a pet fee?+

Yes. A pet deposit (refundable) is returned if there's no pet damage. A pet fee (non-refundable) is kept regardless. Some states restrict non-refundable fees. Always clarify in writing which type applies.

What can a landlord deduct from a security deposit?+

Landlords can deduct for unpaid rent, cleaning beyond normal standards, and damage beyond normal wear and tear. Normal wear and tear (carpet wear, minor scuffs) cannot be deducted. Document the unit with photos at move-in and move-out.
