Am I Supposed to Get Interest on My Security Deposit?

By The Penny Plan Editorial Team Published July 13, 2026 7 min read

A friend mentioned getting a small check back with interest when they moved out, and now the question is nagging: is a landlord supposed to be paying interest on a deposit that’s just been sitting there for years?

In short

Whether a security deposit earns interest depends almost entirely on where the rental is located, since interest-on-deposit rules are set at the state or sometimes city level rather than being a nationwide requirement. Some places require it, many don’t, and the rate and payout method vary widely where it does apply.

Why this isn’t a universal rule

A security deposit is money held by a landlord as protection against damage or unpaid rent, and in most of the country there’s no general federal law requiring that money to earn interest while it sits in the landlord’s account. A number of states and certain cities have added their own requirements, often tying the interest rate to a benchmark like a savings account rate or setting a fixed percentage in local law, but plenty of other jurisdictions have no such requirement at all. This patchwork is why the same lease term can mean a payout in one city and nothing at all a few miles away in a different jurisdiction.

How the interest is usually handled

How to find out what applies to a specific unit

The lease itself is the first place to look, since some landlords voluntarily disclose interest terms even where not legally required. Beyond that, a state or city’s official housing or consumer affairs agency typically publishes the current deposit rules for that jurisdiction, including whether interest applies and how it’s calculated. Because these rules can also change over time, checking the current version through an official source is more reliable than relying on what a rule used to say a few years back. Anyone dealing with a deposit dispute more broadly may also find it useful to review what’s generally covered during a final move-out walkthrough, since disagreements over deposits often surface at that stage.

What tenants sometimes overlook

It’s easy to assume a deposit is just parked money, but the interest question is really a reminder that a deposit is still the tenant’s money, held temporarily under specific rules, similar in spirit to disputes over who is responsible for mold damage found at move-out — both hinge on understanding exactly what a deposit does and doesn’t cover. Tenants sometimes only discover an interest requirement existed after they’ve already moved out and the payout period has passed, which is one reason it can help to ask about it directly when signing a lease rather than waiting until move-out. Building a habit of tracking security deposit terms alongside other renting costs fits into broader planning, including comparisons like how amenity fees quietly affect real monthly rent, since both are examples of money tied up in a lease that’s easy to lose track of.

The takeaway

Interest on a security deposit is a real requirement in some places and simply doesn’t exist as a rule in others, so the honest answer to “am I supposed to get this” depends on local law rather than a single national standard. Checking the lease and the relevant state or city housing authority is the most reliable way to find out what actually applies to a specific unit.
