Security Deposit Calculator

Enter monthly rent and the deposit multiplier to calculate the total security deposit due.

0Security deposit due

Security deposits are commonly set as a multiple of monthly rent — often one month, sometimes one and a half or two, depending on local regulations, the landlord's policy, and factors like credit history or pet ownership.

This calculator multiplies your monthly rent by whatever deposit multiplier applies to your lease, giving the exact dollar amount due, which is useful for budgeting a move or double-checking that a quoted deposit figure matches expectations.

Many jurisdictions cap the maximum security deposit landlords can legally charge, often at one or two months' rent — check your local tenant protection laws if a requested deposit seems unusually high for your area.

This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.

A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.

If you find yourself needing this often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.

The interface is intentionally simple, so there's no learning curve — the input goes in, the result comes out, and that's the whole interaction.

Frequently asked questions

Is there a legal limit on how much a security deposit can be?

Many US states and other jurisdictions cap security deposits at a maximum multiple of monthly rent (commonly one to two months), though rules vary significantly by location — check your local tenant law for specifics.

Can a landlord charge a higher deposit for pets?

Some jurisdictions allow an additional pet deposit on top of the standard security deposit, while others regulate or prohibit it — again, this varies by local law.
