How much cash will you need to move in? This free security deposit calculator turns your monthly rent and a deposit multiplier into a dollar amount, plus your total move-in cost including first month’s rent.
Deposit rules and maximums vary by state and even city – check your local landlord-tenant laws.
Some areas cap deposits (often at 1-2x rent) or require deposits held in a separate interest-bearing account – check your local regulations.
How the Security Deposit Calculator Works
A security deposit is typically set as a multiple of your monthly rent, and the amount you owe upfront depends entirely on which multiplier your landlord applies. This calculator turns your monthly rent and a chosen deposit multiplier into a dollar figure, then adds first month’s rent to show your full move-in cost.
Formula: Security Deposit = Monthly Rent × Deposit Multiplier. Total Move-In Cost = Security Deposit + Monthly Rent (first month’s rent).
- Monthly rent — the dollar amount you pay in rent each month, entered in the Monthly rent field.
- Deposit multiplier — the number of months’ rent your landlord charges as a deposit, selected as 1x, 1.5x, or 2x.
- Security deposit — the calculated result: monthly rent multiplied by the chosen multiplier.
- First month’s rent — added on top of the deposit to show the total cash needed at move-in.

Security Deposit Calculator FAQ
How much can a landlord legally charge for a security deposit?
Limits vary widely by state and sometimes by city, with many jurisdictions capping deposits at one or two months’ rent while others set no cap at all. Always check your local landlord-tenant laws before assuming a multiplier is allowed.Is my security deposit refundable when I move out?
In most places, yes, minus any legitimate deductions for unpaid rent or damage beyond normal wear and tear. Landlords are typically required to return the balance, often with an itemized list of deductions, within a set number of days after you vacate.What’s the difference between a security deposit and first month’s rent?
First month’s rent pays for your initial period of occupancy, while the security deposit is held separately as protection against damage or unpaid rent. This calculator adds both together so you can see the full amount due before you get the keys.Can a landlord charge more than 2x rent for a security deposit?
In some states there is no legal maximum, so a landlord could ask for more, though it’s uncommon in most competitive rental markets. Many other states cap deposits at one or two months’ rent, so check your local rules if a request seems unusually high.Does a security deposit earn interest?
Some states and cities require landlords to hold deposits in an interest-bearing account and pay tenants the accrued interest annually or at move-out. This isn’t universal, so ask your landlord directly or check your local tenant protection statutes.What can a landlord deduct from my security deposit?
Common deductions include unpaid rent, damage beyond normal wear and tear, and sometimes cleaning costs specified in your lease. Routine wear like minor carpet fading or small nail holes generally cannot be deducted under most tenant protection laws.Related Calculators
