What this calculator does

Run this scenario in DocketMath using the Offer Of Judgment Analyzer calculator.

DocketMath’s Offer of Judgment Analyzer helps you estimate how an offer of judgment in Minnesota can affect the judgment amount—especially the add-on of post-offer interest that the court may award when a party beats (or fails to meet) the offer terms.

In Minnesota, the key money math often turns on:

  • The principal judgment (the base amount awarded)
  • Pre-judgment interest rules (if applicable in the underlying claim type)
  • Post-judgment (and/or post-offer) interest at 4% per year for money judgments
  • Whether the offeree’s result is more favorable than the offer (triggering different cost/interest consequences)

For interest specifically, Minnesota provides a default rule:

  • Minn. Stat. § 548.14: “Interest shall be allowed on all money judgments at the rate of 4 percent per annum…”
  • Minn. Stat. § 550.37: addresses interest accrual mechanics, including compounding where applicable and timing concepts courts apply with interest awards.

Your output is an estimate—use it for budgeting and negotiation planning, not as a substitute for a lawyer’s review of your case record, offer wording, and the final judgment language.

Note: This guide focuses on interest calculations connected to Minnesota money judgments, anchored in Minn. Stat. § 548.14 and related interest treatment under Minn. Stat. § 550.37. Offer-of-judgment consequences can also depend on the procedural posture and the exact offer terms.

When to use it

Use DocketMath’s Offer of Judgment Analyzer when you need to quantify “what happens if” around an offer and a later outcome in Minnesota litigation.

Common timing triggers include:

  • After a judgment is entered and you want to estimate the interest portion that may attach under Minn. Stat. § 548.14.
  • Right after the offer deadline passes, when you’re evaluating settlement leverage and want to compare:
    • the offer amount vs.
    • the expected (or actual) judgment and
    • the interest that could accrue at 4% per annum.
  • When recalculating after an amended judgment to see how a new date range changes interest.

A helpful checklist before you run the analyzer:

Warning: Minnesota interest rules can interact with other provisions depending on the claim and judgment structure. The calculator is best used as an estimate of the interest and offer comparison mechanics—not a guaranteed prediction of the court’s final award.

Step-by-step example

Below is a concrete walkthrough using realistic numbers to show how the inputs affect results. (The exact UI labels may differ slightly, but the math logic is the same.)

Scenario

  • You are the plaintiff.
  • You make an offer of judgment in Minnesota for $25,000.
  • The court later enters a money judgment for $30,000.
  • You want to estimate interest from a start date to a target end date.

Assume:

  • Principal judgment: $30,000
  • Interest rate applied by rule: 4% per year under Minn. Stat. § 548.14
  • Interest start date: June 1, 2025
  • Interest end date: December 1, 2025

Step 1: Enter the principal

  • Principal judgment amount: 30000

How it changes outputs:
Interest is computed as a percentage of the principal. Higher judgment = higher interest at 4% per annum.

Step 2: Enter the interest date range

  • Start date: 2025-06-01
  • End date: 2025-12-01

How it changes outputs:
Even if the rate is fixed at 4%, the number of days drives the interest amount.

To sanity check the math:

  • June 1 to December 1 is 183 days (calendar-day count).

Step 3: Apply the statutory rate (4%)

Minnesota’s default interest on money judgments is 4% per annum under Minn. Stat. § 548.14.

A common day-count approach for estimates is:

  • Interest ≈ Principal × 0.04 × (Days / 365)
  • Interest ≈ $30,000 × 0.04 × (183 / 365)
  • Interest ≈ $30,000 × 0.04 × 0.50137
  • Interest ≈ $602.00 (rounded)

Step 4: Compare offer vs. judgment amount

Now compare:

  • Offer: $25,000
  • Judgment: $30,000

Impact on leverage (estimation purpose):
If the offer rules in your case treat an outcome as “beating” the offer, the court may factor that into costs/interest consequences. This analyzer can help you quantify the money delta and the interest window, but the procedural triggering and exact consequences should be checked against your docket and offer language.

Step 5: Read the analyzer results

Typical outputs include:

  • Estimated interest amount
  • Estimated total (principal + interest)
  • Potential offer vs. outcome delta (depending on how the tool is configured)

Example:

  • Estimated interest: ~$602
  • Estimated total: $30,000 + $602 = $30,602

Pitfall: If you input the wrong date range (for example, using the offer date when the court’s interest start date differs), your interest estimate can swing by hundreds of dollars over multi-month periods—even with a fixed 4% rate under Minn. Stat. § 548.14.

Common scenarios

Minnesota offers can play out differently depending on what the final judgment looks like relative to the offer, and how the judgment’s dates and components are structured. Here are scenarios where people typically use the DocketMath analyzer.

1) Judgment is higher than the offer

  • Offer: $25,000
  • Judgment: $30,000
    Expected analyzer use:
  • Quantify the principal difference ($5,000) and the interest accrual window at 4% under Minn. Stat. § 548.14.

2) Judgment is equal to the offer

  • Offer: $25,000
  • Judgment: $25,000
    Expected analyzer use:
  • Model interest impact without a principal delta.
    Watchouts:
  • Some outcomes still hinge on procedural eligibility and timing of the offer.

3) Judgment is lower than the offer

  • Offer: $25,000
  • Judgment: $18,000
    Expected analyzer use:
  • Estimate total exposure and compare it against the offer amount to understand why the offer may be “less favorable.”

4) Amended judgment / post-trial correction changes the number or dates

  • Principal or date range changes after amendment
    Expected analyzer use:
  • Re-run the calculation using the new judgment date or adjusted end date.
  • Minnesota interest math remains anchored at 4% per annum for money judgments under Minn. Stat. § 548.14, but the start/stop dates you input drive the estimate.

5) Interest-only budgeting before a judgment is final

Some users run the analyzer with a “working estimate” of the principal to understand:

  • how much interest could accrue if the case runs an extra 30/60/90 days, and
  • what that means relative to the offer amount.

A quick budgeting perspective:

  • Every additional day adds about:
    Principal × 0.04 / 365
  • Example with $30,000 principal:
    $30,000 × 0.04 / 365 ≈ $3.29/day (estimate)

Note: DocketMath is designed to compute based on the numeric inputs you provide. If your final judgment includes multiple components (for example, damages plus separate awards), you may need to run the analyzer separately or input the correct principal figure that matches your intended interest base.

Tips for accuracy

Small input choices matter, especially when interest is calculated over months. These steps will make the analyzer output more defensible for internal review.

1) Confirm the principal amount you’re using

  • Use the final damages/judgment number you expect interest to attach to.
  • If the judgment is split into components, decide whether you’re estimating:
    • a single combined principal, or
    • interest separately by component.

2) Use consistent date logic

Minnesota’s interest on money judgments uses 4% per annum under Minn. Stat. § 548.14. The rate is straightforward; the date range is not.

Before you click calculate, verify:

  • Are you using the correct start date for the interest period?
  • Is your end date:
    • the date you plan to model (e.g., payment date estimate), or
    • the date you want to match to a specific document (e.g., cutoff for a settlement memo)?

3) Keep your numbers aligned with the analyzer’s assumptions

  • Enter amounts as whole dollars if the tool expects integers; otherwise use decimals consistently.
  • If the tool distinguishes between “offer amount” and “judgment amount,” don’t paste the same number into both fields unless that’s intentional.

4) Cross-check the rate quickly against the statutory baseline

Your interest estimate should roughly match this baseline:

  • Annual interest ≈ Principal × 0.04
  • Monthly interest (rough estimate) ≈ Principal × 0.04 / 12

Example: $30,000 principal

  • Annual interest
