Landlord Tenant Damages Calculator
Quantify the total amount a tenant owes a landlord for unpaid rent, property damage, and security deposit offsets. Use this during eviction proceedings or small claims court preparation.
About this calculator
When a tenancy ends in dispute, landlords need a clear accounting of all money owed. This calculator uses the formula: Total Damages = (Monthly Rent × Months Unpaid) + Property Damage Cost − Security Deposit. The first term captures rent arrears — each month of non-payment multiplied by the contracted rent. Property damage costs cover repairs beyond normal wear and tear, documented by invoices or contractor estimates. The security deposit is then subtracted because it has already been collected and legally applied to these obligations. The resulting figure represents the net amount the landlord can sue for in civil court or small claims. Note that some jurisdictions cap recoverable damages or allow tenants to counter-claim for wrongful withholding of deposits.
How to use
A tenant paid $1,200/month but stopped paying rent 3 months ago and left the unit with $800 in damage. The security deposit on file is $1,500. Step 1 — Rent arrears: $1,200 × 3 = $3,600. Step 2 — Add damage: $3,600 + $800 = $4,400. Step 3 — Subtract deposit: $4,400 − $1,500 = $2,900. The landlord's net recoverable damages are $2,900. This amount can be pursued through small claims court (limits vary by state) or a civil lawsuit.
Frequently asked questions
What damages can a landlord recover from a tenant in court?
Landlords can generally recover unpaid rent, costs to repair damage beyond normal wear and tear, cleaning fees if the unit was left in an unacceptable condition, and sometimes lost rent for the period it takes to re-rent the unit. Courts typically disallow claims for cosmetic issues that existed before the tenancy or for normal depreciation of fixtures. Documentation — photos, move-in/move-out checklists, and contractor invoices — is essential for substantiating these claims.
How does the security deposit affect landlord damage calculations?
The security deposit functions as a pre-collected buffer against tenant-caused losses. Legally, it must be applied to any valid claim before the landlord can sue for additional amounts. In this calculator it is subtracted from the gross damages total, giving the net out-of-pocket claim. If the deposit exceeds the damages, the landlord owes the tenant the difference — and failing to return that overage within the statutory deadline (commonly 14–30 days, depending on state) can expose the landlord to penalties of 2× or 3× the deposit amount.
What is the difference between normal wear and tear and property damage in a landlord-tenant dispute?
Normal wear and tear refers to the gradual, expected deterioration that occurs through ordinary use — scuffs on baseboards, minor carpet wear, or faded paint after several years. Landlords cannot deduct these from a security deposit. Property damage, by contrast, is harm caused by negligence or misuse: large holes in walls, broken fixtures, pet stains, or burns. The line can be blurry and is frequently litigated. Courts look at the age of the item, the length of tenancy, and photographic evidence from both move-in and move-out inspections to make the determination.
