State law matters
Many states cap security deposits at 1–2 months of rent. Some states count last-month rent toward the cap (CA, MA, NY); others don't. Most states require deposits in a separate trust or escrow account and pay interest in some jurisdictions.
Always check your specific state and local rules before charging. Pet deposits and pet rent are separate from security deposits in many states. Key/fob deposits are usually allowed and refundable.
How to Use
- Enter the monthly rent.
- Enter your state's deposit cap as months of rent (often 1–2 months; some states have no cap).
- Set whether you'll collect last-month rent (counts toward the cap in some states).
- Enter pet deposit and key/fob deposit if applicable.
- Read total move-in money and verify the deposit + last-month total stays under your state's cap.
Frequently Asked Questions
How much can I charge for a security deposit?
It depends on state law. Common caps: 1 month (NY, MA), 2 months (CA non-furnished, NJ, MN), 3 months (some Florida circumstances), no cap (TX, GA, FL primary). Always verify current state and local law.
Does last-month rent count toward the cap?
In some states (CA, MA, NJ) yes — last-month rent collected upfront counts toward the security deposit limit. In others, it's separate. The calculator flags if you exceed the cap.
Can I keep all of the deposit if a tenant moves out?
Only the portion needed to cover unpaid rent and damage beyond normal wear and tear. Most states require itemized accounting with returned funds within 14–30 days. Withholding without itemization can trigger statutory penalties (sometimes 2–3x the deposit).
Are pet deposits separate from security deposits?
In many states, yes — pet deposits, pet rent, and one-time pet fees are governed by different rules. Some states count pet deposits in the overall cap; others don't. ESA/service animals can't be charged a pet deposit at all.
