About This Calculator
The Security Deposit Calculator helps landlords calculate deposit amounts, document deductions accurately, and determine the correct refund at move-out. For tenants, it helps understand what can legally be deducted.
Most states cap security deposits at 1–2 months rent. Always verify your state's specific limits. Landlords must return the deposit (with itemized deductions) within a legally specified timeframe — typically 14–30 days after move-out.
Key rule: you can only deduct for damages beyond normal wear and tear. Normal wear and tear (minor scuffs, carpet wear from regular use) cannot be charged to the tenant. Document property condition with photos at both move-in and move-out.
