Your deposit may earn more than a few cents, but the amount depends on where you rent. Security deposit interest rules vary by state and city, so check the rate, payment date, and any local exceptions before move-out.
We analyzed 31 comments and questions from Reddit, Quora and YouTube about security deposit interest and found that 32% asked about a landlord's obligation to pay interest.
Some places tie the rate to a local formula. Others require a share of the interest earned, while some don’t set a specific rate. Here’s how to read the rules and ask for the amount due.
What Security Deposit Interest Means: Where the Rules Come From
Security deposit interest is money earned while a landlord holds your deposit. The deposit remains your money, subject to lawful deductions. Interest may be owed on top of the deposit, but only if the rule that covers your rental requires it.
Rules can come from state law, a city or county ordinance, or a local rent board. A state may set a rate for some rentals and leave other details to a city. Residential lease comparison charts may be organized by jurisdiction, which reflects why a renter needs to check the rules for the property’s location.
Some rules apply only when a deposit is above a set amount or has been held for a minimum time. In New York, the listed exemption applies to landlords with six or more units. Residents may choose annual payment, a rent rebate, or payment at the end of tenancy. Other listed exceptions turn on a deposit threshold or a holding period.
Don’t treat a state summary as the final word if your city has its own rule. A useful starting point is the lease: look for the deposit amount, where it is held, and any language about interest. LeaseGuard AI reviews lease terms for fees and tenant-protection issues, but the local law still decides whether interest is due. If you need a refresher on what the deposit itself covers, see what a security deposit is and how it works.
How Deposit Interest Is Calculated and How Rates Vary
The math depends on the local rule and the way the money is held. A rule may use simple interest, a rate set each year, or a share of interest earned by the account. Some formulas also account for deposits made at different times or for money properly withheld for damage.
For simple interest, the basic calculation is deposit × annual rate × time held. For example, if a deposit earns simple interest over a year, the interest is the deposit multiplied by the annual rate. For a shorter period, adjust for the time held.
That example is only a math illustration, not a rule for any state. A local formula may use a different rate or compounding method. The deposit-interest guidance is a reminder to check the date and method in the governing rule.
The rates can differ sharply. Chicago’s rate is 0.01%, while Florida requires 75% of the account’s interest. These examples aren’t a national rate table. They show why a broad average can mislead: the formula may be a set percentage, a share of actual earnings, or a locally updated figure.
Rates tied to bank returns may change over time. A fixed legal percentage may not move with the market at all. Check which rate applies to the period your landlord held the funds, and whether a local authority updates it each year.

Landlord Duties, Payment Timing, and How Renters Can Claim Interest
When local law requires interest, the landlord must follow its rules for holding the deposit and paying the amount due. The deadline may be annual, at the end of the tenancy, or based on a tenant’s choice. Don’t assume interest will arrive with the original deposit refund unless the local rule says so.
At move-out, compare the deposit statement with your records. Check the original amount and how long the landlord held it. Then compare any deductions with the lease and the rules for your location. A landlord may be allowed to deduct for unpaid rent or tenant-caused damage, but ordinary wear and tear is different from damage.
If the interest isn’t shown, send a dated written request. Ask the landlord to state the rate used, the time period, and how the final amount was calculated. Keep a copy of your lease, deposit receipt, move-out photos, messages, and any statement the landlord sends. These records help if you need to dispute the amount later.
Next, check the local complaint process or seek help from a tenant-rights group or lawyer. Deadlines and remedies vary, so don’t assume a rule from another state applies to you. If the main dispute is a missing refund or an unexplained deduction, the steps in what to do when a landlord doesn’t return a deposit can help you organize your next move.
For example, if your landlord returns the deposit but says nothing about interest, ask whether interest was due under the local rule. If the landlord says it was included, request the calculation rather than guessing from the total check amount.
Special Cases: Taxes, Damages, Short-Term Rentals, and Commercial Leases
Taxes on deposit interest
Interest that is paid or credited to you may have tax effects. The details can depend on who received the earnings and how the payment was handled. Keep any year-end tax form or statement from the landlord, and check current federal tax guidance or ask a tax professional if you’re unsure how to report it.
When part of the deposit covers damage
A lawful deduction can reduce the amount held and may change the interest calculation. The exact treatment depends on the local formula. Ask the landlord to separate the deposit balance, any damage deduction, and the interest calculation instead of accepting one unexplained total.
Take move-in and move-out photos when possible. A dated record can help you distinguish normal wear from damage and question a deduction that does not match the unit’s condition. LeaseGuard AI can help you review lease language before signing, but it can’t decide whether a later damage claim is legally valid.
Short-term rentals
A stay booked for a few nights may be treated differently from a residential tenancy. Don’t assume a short-term booking follows the same deposit-interest rules as a year-long apartment lease. Read the booking terms and check the law that applies to the property and type of stay.
Commercial leases
Commercial deposits can follow different terms from residential deposits. A business lease may set out how the deposit is held and whether earnings are credited to the tenant. State rules can still matter, so review both the contract and applicable law before relying on a clause.
For renters reviewing a residential lease, a clause that says the deposit earns no interest isn’t automatically the last word. The local rule may control. LeaseGuard AI can flag lease language for review, and its report is informational only.
Frequently Asked Questions
Do all states require landlords to pay interest on security deposits?
No, there isn’t one nationwide rule that requires interest on every deposit. Requirements depend on state and local law, and some rules apply only to certain landlords or deposits. Check the law where the rental sits, including any city or county rule. A lease clause may describe the process, but it can’t replace a law that applies.
How do I calculate interest on my security deposit?
Use the method required by the law that applies to your rental. A simple-interest calculation uses the deposit amount, annual rate, and time held, but local rules may use a different formula or account earnings. Ask the landlord for the method and dates used, then compare them with your deposit receipt and the relevant local guidance.
When should a landlord pay deposit interest?
The timing depends on the state or local rule. Some jurisdictions require annual payment, while others settle the interest at move-out. A rule may also let the renter choose how to receive it. Check your lease and local law, then ask for the payment date in writing if the interest is not included with the deposit statement.
Can a landlord use the interest to pay for damage?
Sometimes the rule allows interest to be reduced by lawful damage deductions, but the details vary by location. Ask for an itemized statement that separates the original deposit, the interest calculation, and each deduction. Compare the claimed damage with your move-in and move-out records. Normal wear and tear may be treated differently from tenant-caused damage.
Does a short-term rental deposit earn interest?
Not necessarily. A short booking may not fall under the same rules as a residential lease, and the contract may use different terms. Check the booking agreement and the law that applies to the rental’s location. If the stay is governed by residential tenancy law, use that law’s deposit rules rather than assuming the booking label decides the issue.

Conclusion
Check the local rule before you accept a deposit statement as final. Save your lease and payment records, then request the calculation in writing if interest is missing.
