How to Calculate Damages for New Mexico Small Claims Court

Why the Number Matters

The amount you put on your complaint form determines whether your case fits in small claims court ($10,000 limit in New Mexico) and what the judge can award. Overstate your damages and you lose credibility. Understate them and you leave money on the table — you can't come back for the difference later. Getting the number right before you file is essential.

Types of Damages in Small Claims

Contract damages. When someone breaks a contract, you're entitled to the benefit of the bargain — what you would have received if the contract had been performed. If you paid a contractor $5,000 for a kitchen renovation and they walked off after demolition, your damages are what it costs to hire someone else to finish the job minus any value the first contractor actually delivered.

Property damage (tort). The measure is the cost to repair the damaged property. If repair isn't practical, it's the fair market value of the property at the time of damage — not the replacement cost of a new item. A five-year-old laptop isn't worth what a new one costs.

Unpaid debt. Straightforward — the principal amount owed, supported by the invoice, contract, or written agreement.

Security deposit claims. Under NMSA § 47-8-18, if a landlord fails to return your deposit or provide an itemized deduction statement within 30 days, you must make a written demand before claiming the $250 bad-faith statutory penalty and reasonable attorney fees; this demand is not required to claim the deposit itself.

Building the Calculation

Start with the core loss, then add allowable amounts:

Punitive damages are not usual; New Mexico court guidance says they can be awarded only if the court also awards compensatory damages. Claim attorney's fees only when a statute authorizes them, such as for some security deposit claims, and support each amount with evidence.

The $10,000 Ceiling

Your total claim — principal damages only — must stay at or under $10,000. Interest and court costs are calculated outside this cap. If your actual losses exceed $10,000, you have two choices:

1. Waive the excess — file in small claims for $10,000 and permanently give up the rest
2. File in District Court — pursue the full amount, but with more complex procedures and potentially longer timelines

You cannot split a single claim into multiple lawsuits to stay under the limit. That's claim splitting, and it's prohibited under res judicata rules.

Getting Repair Estimates Right

Judges take professional estimates seriously and skeptically eyeball DIY calculations. For property damage and construction disputes:

• Get at least two written estimates from licensed, independent contractors
• Each estimate should separate labor from materials
• The estimates should describe the same scope of work
• If estimates vary widely, be prepared to explain why you're relying on one over the other

If you've already completed repairs, bring the paid invoices and receipts instead. The actual cost of repair is the strongest evidence of damages.

Post-Judgment Interest

Once the judge enters a judgment in your favor, interest generally accrues automatically at 8.75% per year under NMSA § 56-8-4, unless a written agreement specifies a different contractual rate. For a tort claim resulting from an insured defendant's tortious conduct or negligence, the rate is 15% per year. This interest is statutory — you don't need to ask for it.
