How the Demand Letter ROI Calculator Works

This calculator compares the expected return on investment (ROI) of four different paths for collecting money owed to you. It uses expected value analysis -- a standard financial decision-making framework -- to account for both the probability of success and the total cost (money and time) of each option.

The Expected Value Formula

For each collection path, we calculate the expected net value using this formula:

Net Expected Value = (Claim Amount x Success Rate) - Direct Costs - (Your Hours x Hourly Time Value)

For example, if your claim is $5,000 and you choose an attorney demand letter with a 50% success rate at $575 cost with 1 hour of your time valued at $50/hr: Expected Net Value = ($5,000 x 0.50) - $575 - ($50 x 1) = $1,875.

How Success Rates Are Determined

Base success rates for each path are derived from published legal industry data and adjusted by two factors you provide:

  • Claim type: Unpaid invoices and security deposit claims have higher collection rates than complex contract breach or employment claims because the amounts are more easily proven.
  • Evidence strength: Your self-assessed success probability (1-5 scale) adjusts the base rate up or down. Strong documentation, signed contracts, and written correspondence improve your chances significantly.

What the ROI Percentage Means

ROI is calculated as: ROI = (Net Expected Value / Total Cost) x 100. A positive ROI means you are expected to recover more than you spend. A higher ROI means a better return per dollar invested. This calculator highlights the path with the highest ROI as the recommended option.

Important Assumptions

  • Success rates are estimates based on industry averages and may vary by jurisdiction and individual circumstances.
  • Small claims filing fees are approximated by state but may differ by county or claim amount.
  • Attorney demand letter pricing is based on Terms.Law's $575 flat fee for a professionally drafted demand letter.
  • Litigation costs assume standard civil litigation with hourly-rate attorneys.
  • Time estimates assume an average case complexity. Highly contested matters may require more time.

Data Sources

  • American Bar Association litigation cost surveys
  • National Center for State Courts small claims data
  • State-by-state small claims filing fee schedules (verified March 2026)
  • Terms.Law internal demand letter resolution data

Detailed Path Comparison: 4 Ways to Collect What You Are Owed

Each collection path has tradeoffs between cost, time, success probability, and stress. Here is a detailed breakdown to help you decide which approach is right for your situation.

Path 1: DIY Demand Letter ($0-30)

Writing and sending your own demand letter is the lowest-cost option. You draft the letter yourself, send it via certified mail ($15-30), and wait for a response. The advantage is minimal financial outlay. The disadvantage is that recipients often ignore DIY letters because there is no credible legal threat behind them. Without an attorney's letterhead and case citations, the debtor may conclude that you are unlikely to take further action.

Best for: Small claims under $500 where you have a strong personal relationship with the debtor, or as a preliminary step before escalating.

Path 2: Attorney Demand Letter ($575 Flat Fee)

A professionally drafted demand letter on law firm letterhead signals that you are serious and have legal counsel. The letter includes proper legal citations, statutory interest calculations, and a clear deadline. Recipients know that ignoring an attorney's letter may lead to litigation. This is why attorney demand letters achieve 2-3x the success rate of DIY letters.

Best for: Claims between $1,000 and $25,000. This is typically the highest-ROI option because the cost is fixed and low relative to the improved success rate.

Path 3: Small Claims Court ($30-200 Filing Fee + Your Time)

Small claims court is designed for individuals to resolve disputes without attorneys. Filing fees are modest ($30-200 depending on state and claim amount), but you must invest significant time: preparing filings, gathering evidence, attending hearings, and potentially waiting months for a court date. Small claims limits vary by state, from $2,500 (Kentucky) to $25,000 (Tennessee).

Best for: Claims under your state's small claims limit where the demand letter failed and you have strong written evidence.

Path 4: Full Litigation ($3,000-10,000+ Retainer)

Hiring an attorney on retainer for civil litigation provides the highest success rates but at the highest cost. Attorney retainers typically start at $3,000-5,000, with hourly rates of $200-500. Total litigation costs for even straightforward cases can reach $10,000-30,000. A lawsuit also demands significant time for depositions, discovery, and court appearances.

Best for: Claims over $25,000, complex disputes involving multiple parties, or cases where the principle matters as much as the money.
