How to calculate Offer Of Judgment Analyzer in Montana

Quick takeaways

• Montana’s Offer of Judgment rule is in Mont. R. Civ. P. 68 and hinges on whether the final result is “more favorable” to the offeree than the unaccepted offer.
• The key timing requirement is that the offer must be served more than 14 days before the date set for trial (Mont. R. Civ. P. 68).
• In DocketMath’s Offer Of Judgment Analyzer (US-MT), your inputs drive the outcome by comparing:

  • the offer amount (and any specified terms you enter), versus
  • the final judgment outcome you enter.
• Changing your offer date, trial date, or judgment amount can flip whether the result is treated as more favorable (and therefore flips the analyzer’s consequence modeling).
• This guide explains how to run the math in the calculator and what each input means under the rule’s framework—not legal advice.

Inputs you need

To calculate with DocketMath’s Offer Of Judgment Analyzer for Montana (US-MT), collect the following up front.

1) Offer details (what was served)

• Offer served date

  • The calendar date you entered/served the offer.
• Offer amount (and/or specified terms)

  • The dollar figure (or terms) you want the analyzer to treat as the “unaccepted offer.”
• Costs treatment assumptions (if your scenario needs them)

  • If the calculator asks for costs, gather an amount you want to model (e.g., estimated recoverable costs or the costs accrued framework you intend to use).
  • If you only want to understand the “more favorable” threshold without trying to model cost economics, you can focus on the offer vs. final judgment inputs.

2) Trial timing (to satisfy Montana’s timing requirement)

• Trial date

  • The date set for trial that you are using as your comparison point.

Montana’s rule requires the offer be served “more than 14 days before the date set for trial.” (Mont. R. Civ. P. 68)

3) Final outcome (what the offeree ultimately obtains)

• Final judgment amount obtained by the offeree

  • The number you want to compare against the offer.
• What you want the analyzer to treat as “more favorable”

  • Practically, this calculator uses the numbers you enter to decide whether the final judgment is treated as more favorable than the unaccepted offer (based on the analyzer’s dollar-based comparison inputs).

4) Optional (if you’re modeling more complete economics)

Depending on how the tool flow is set up for your scenario, you may also provide:

• Post-offer interest assumptions (if prompted)
• Attorney fee assumptions (only if the calculator requires them and you can supply a reasonable, supportable figure)

If your calculator version does not require these inputs, don’t force them—stick to the core offer-vs-judgment and timing inputs.

How the calculation works

DocketMath’s Offer Of Judgment Analyzer (US-MT) follows a calculator-friendly sequence based on Montana’s rule logic: timing check → “more favorable” comparison → modeled consequence.

Step 1: Confirm Montana’s timing window

Under Mont. R. Civ. P. 68, the defender may serve an offer “more than 14 days before the date set for trial.”

What the calculator does with your dates:

• Uses your offer served date and trial date
• Computes the time gap
• Flags whether the “more than 14 days” condition is satisfied

Practical rule of thumb for your entries:

• Offer served 14 days or fewer before the trial date → timing requirement not met
• Offer served 15+ days before the trial date → timing requirement met

Step 2: Compare “more favorable” outcomes (offer vs. final judgment)

Montana’s framework turns on whether the offeree ultimately obtains a judgment more favorable than the unaccepted offer.

The statute text you’re using includes this core consequence concept:

• If the judgment the offeree finally obtains is not more favorable than the unaccepted offer, the rule’s consequence language applies.

How DocketMath applies this comparison:

• It compares the offer amount you enter against the final judgment amount you enter.
• Based on that comparison (as structured by the calculator’s inputs), the tool categorizes the modeled outcome as:

  • More favorable (offer beaten), or
  • Not more favorable (offer not beaten)

Because “more favorable” can depend on what the offer/terms include, keep your inputs consistent:

• If you are only entering a principal dollar amount, the comparison is effectively dollar-based on that principal.
• If the scenario includes cost/terms economics and the tool supports those inputs, then include them using the tool’s expected fields.

Step 3: Model consequence effects using costs/terms inputs (when applicable)

Montana’s rule text references offers on “specified terms” and addresses “costs then accrued,” with consequences that turn on whether the final judgment is more favorable.

In calculator terms, DocketMath typically lets you model consequences through the combination of:

• Timing (did you meet the “more than 14 days” requirement?), and
• Outcome comparison (is the final judgment more favorable?), and
• Economics inputs (e.g., costs or other modeled terms, if the calculator includes them)

Checklist for better modeling:

• Use the same framing for both numbers:

  • example: if you enter total dollars for the offer, enter total dollars for the final judgment.
• Only enter costs/fees if you’re comfortable that your number matches the scope you intend to model.

Step 4: Interpret the output the way the tool intends

After you run the scenario in Offer Of Judgment Analyzer (US-MT), you should look for outputs that correspond to:

• Whether Montana’s timing requirement is satisfied
• Whether the final judgment is treated as more favorable than the unaccepted offer
• The modeled financial consequence based on the inputs you supplied

Common pitfalls

These are common reasons offer-of-judgment calculator results don’t match what people expect in Montana.

• Entering incorrect dates

  • Montana uses the “more than 14 days before the date set for trial” rule (Mont. R. Civ. P. 68).
  • A small date-entry error (even near the 14-day boundary) can flip the timing flag.

• Mixing up what’s being compared

  • The relevant comparison is between the unaccepted offer and the judgment the offeree ultimately obtains.
  • If your “final judgment” input is not the number you actually want compared, the “more favorable” determination can be wrong.

• Ignoring the “specified terms” concept

  • Montana’s rule contemplates offers on specified terms.
  • If your case economics depend on more than principal (and the calculator supports those fields), limiting your inputs can make the modeled result incomplete.

• Assuming a claim-type-specific timeline exists

  • For Montana in this calculator approach, use the general/default window: more than 14 days before trial under Mont. R. Civ. P. 68.
  • Don’t look for a special category-specific serving period unless you have case-specific authority.

• Using inconsistent costs assumptions

  • If the calculator uses costs, make sure your costs figure matches what you intend (e.g., the costs the tool expects to represent).
  • Inconsistent scope (principal-only vs. principal-plus-cost modeling) can distort the output.

Next steps

1. Open DocketMath’s calculator:

   • /tools/offer-of-judgment-analyzer

2. Enter your timing anchors:

   • offer served date
   • trial date
     Then verify the tool shows the offer was served more than 14 days before trial.

3. Enter the comparison numbers:

   • offer amount
   • final judgment amount obtained by the offeree
     Make sure both use the same unit and framing.

4. If your scenario includes costs/terms inputs in the tool:

   • add those values so the calculator can reflect the modeled consequence you want to analyze.
