Impact Calculator Guide for Utah

Run this scenario in DocketMath using the Impact calculator.

DocketMath’s Impact Calculator helps you estimate how interest on money judgments can affect the total amount due over time in Utah. Use it to model “what-if” timelines, compare payoff dates, and sanity-check how delays in satisfying a judgment may change the final number.

What this calculator does

DocketMath’s Impact Calculator (Utah) is designed to compute a practical estimate of interest impact using Utah’s statutory framework for interest on “the use of money or the detention of money” in civil actions.

Under Utah Code Ann. § 15-1-1, a person is generally entitled to recover interest for money use or detention. The statute also recognizes key exceptions that can change the rate and can increase interest when a judgment is not satisfied.

Core statutory principles the calculator is built around

• General entitlement to interest
  Utah Code Ann. § 15-1-1 governs when interest may be recovered for the use or detention of money in civil actions.

• Rate depends on the nature of the judgment (exception)
  § 15-1-1(1) allows that the statutory rate may differ based on the nature of the judgment.

• Interest can increase with failure to satisfy the judgment (exception)
  § 15-1-1(2) provides that rates may increase with failure to satisfy a judgment.

Inputs you typically control in the calculator

Depending on your case setup, you’ll usually be working with:

• Principal amount (the dollar amount you’re modeling interest on)
• Start date (when the detention/use begins for your calculation)
• End date / payoff date (when you expect payment)
• Judgment characteristics (used to reflect rate differences and/or satisfaction timing)

Outputs you can expect

When you run the calculator, it generally produces:

• Estimated interest accrued over your selected period
• Estimated total due = principal + interest (and any modeled rate changes)
• A time-based breakdown (how interest grows as days/months pass), if the calculator view includes a schedule

Because interest can be sensitive to date selections and judgment characteristics, the biggest driver of your result is usually the length of time you select and which rate scenario you apply.

When to use it

Use DocketMath’s Impact Calculator in Utah when you’re trying to understand how the math changes as key dates move, especially in money-judgment contexts.

Good times to use the calculator

• You’re estimating payoff impact

  • Example: “If we pay 60 days later, how much more could interest add?”

• You’re comparing settlement timelines

  • Example: “If the parties agree in 30 days vs. 90 days, what’s the difference?”

• You need to budget for delays

  • Example: “Payments might not clear until end of next month.”

• You’re evaluating whether satisfaction timing matters

  • Utah Code Ann. § 15-1-1(2) reflects that rates may increase with failure to satisfy a judgment, which can materially change totals as time passes.

Situations where you should be extra careful

• If the judgment has special language affecting rate or accrual logic
  Since § 15-1-1(1) acknowledges rate may differ based on the nature of the judgment, the wrong assumption about the judgment type can produce an inaccurate estimate.

• If the relevant start date is disputed
  Interest calculations can depend on when money was “detained” or when the legal basis for interest begins in the specific civil action.

Step-by-step example

Below is a concrete example showing how inputs change outputs. This is an illustrative walkthrough of the workflow—actual case facts can change which rate scenario best matches your situation under Utah Code Ann. § 15-1-1.

Scenario

You want to estimate the additional amount that could accrue if payment is made later.

• Principal amount: $10,000
• Start date (detention begins for the estimate): January 1, 2025
• End date / payoff date: April 1, 2025
• Judgment characteristics: Modeled using the statutory interest framework under Utah Code Ann. § 15-1-1

  • Remember: § 15-1-1(1) may change the rate depending on the nature of the judgment.
  • Also consider: § 15-1-1(2) may increase rates if the judgment is not satisfied.

Step 1: Open DocketMath Impact Calculator

Go to the tool: /tools/impact-calculator.

Step 2: Enter the principal

• Enter $10,000 as the principal.

Impact on output:
The principal becomes the base for interest accrual. If you double principal, the interest estimate typically doubles too (all else equal).

Step 3: Enter the start and end dates

• Start date: 2025-01-01
• End date: 2025-04-01

Impact on output:
More days between dates usually means more interest accrues. The calendar span matters because statutory interest accrues over time.

Step 4: Select the rate scenario that matches your judgment type

In the calculator, choose the option that best corresponds to your modeled situation (for Utah, the statute references possible differences based on the “nature of the judgment,” and potential increases with failure to satisfy).

• If your situation fits a scenario where the rate differs due to the judgment’s nature, align the calculator accordingly (Utah Code Ann. § 15-1-1(1)).
• If the judgment is not satisfied by your modeled payoff date and your scenario includes potential rate increases, align the calculator accordingly (Utah Code Ann. § 15-1-1(2)).

Step 5: Run the calculation

Click Calculate.

Step 6: Review the results

The calculator will typically show:

• Estimated interest accrued for the selected period
• Estimated total due = principal + estimated interest
• Often a date-based accumulation (or interest per unit time)

Step 7: Stress-test with two payoff dates

Run it again with a later payoff date to see sensitivity.

• New end date: 2025-05-01 (30 more days)

What you learn:
If interest is roughly linear over short spans, the difference between results (May 1 vs. April 1) approximates daily accrual. Over longer periods or when a rate changes, that difference may accelerate.

Common scenarios

The Utah statute’s structure means common real-world variations often change the interest estimate. Use the calculator to compare scenarios, but keep the statutory drivers in view.

1) Short delay vs. long delay

• Short delay (e.g., 15–45 days):

  • The interest impact may be modest, but still non-trivial depending on principal size.
• Long delay (e.g., 90–180 days):

  • Total due can grow meaningfully, especially if your model includes conditions where rates increase.

Calculator tip:
Compare results side-by-side using two payoff dates and keep the principal and start date fixed.

2) Judgment type changes the applicable rate

Utah Code Ann. § 15-1-1(1) states statutory interest may differ depending on the nature of the judgment.

Common modeling implications:

• If your judgment is the type where a different rate applies, your interest estimate could move up or down.
• Your “total due” becomes sensitive to the selection you make in the calculator for the judgment characteristic.

Checklist

3) Failure to satisfy can increase rates

Under Utah Code Ann. § 15-1-1(2), rates may increase with failure to satisfy a judgment.

What this means in practice:

• Your modeled payoff date isn’t just a “date field”—it can determine whether rate changes apply.
• Two similar calculations with different satisfaction timing can produce different results.

Calculator tip:
Test at least three payoff dates:

4) Disputed start dates

If the “detention/use” start date is unclear, your interest accrual period changes immediately.

Example:

• Start date moved forward by 30 days → estimated interest often drops (all else equal)

Calculator tip:
Model two plausible start dates and use the range to plan.

5) Comparing settlement proposals

If you’re negotiating, the calculator can help you understand how a proposed payment date changes the total economic impact.

Tips for accuracy

To get the best Utah-focused estimate from DocketMath’s Impact Calculator, focus on inputs that most strongly affect interest under Utah Code Ann. § 15-1-1 and its exceptions (§ 15-1-1(1) and § 15-1-1(2)).
