How to calculate pre/post-offer damages split in Kentucky

Quick takeaways

• Kentucky’s pre/post-offer damages split is anchored to Ky. R. Civ. P. 68 (CR 68), which requires the offer to be served “at any time more than 10 days before the trial begins.”
• If CR 68’s timing is satisfied and the case outcome is assessed against the offer, the rule’s “costs then accrued” / “judgment finally obtained” framework affects what portion of the financial picture should be treated as pre-offer vs. post-offer in your accounting narrative.
• In DocketMath’s Pre/Post-Offer Damages calculator (US-KY), you can model a split by providing:

  • the offer service date and trial start date (to enforce the >10-day gate), and
  • the final judgment amount and offer amount (to align the split with the offer-vs-judgment outcome framing).
• Default period clarity: CR 68, as provided in your source, states a general/default timing rule (“more than 10 days before trial begins”). If you don’t see a claim-type-specific sub-rule in the CR 68 text you’re relying on, start from that default.

Inputs you need

Before you use DocketMath to calculate the pre/post-offer damages split for Kentucky (US-KY), gather the inputs below. Most come directly from the docket (offer paperwork, service proof, judgment).

A. Offer and trial timing inputs (CR 68 timing)

• Offer service date

  • The key CR 68 trigger is service (not signing or mailing).
• Trial start date

  • Use the date the trial begins as reflected in the case record.
• Rule timing check (CR 68 gate)

  • Whether the offer was served “more than 10 days before the trial begins”
  • CR 68 default rule (per the provided statute text): “at any time more than 10 days before the trial begins.”

B. Judgment outcome inputs

• Final judgment amount

  • Use the operative final judgment figure—the amount that is “finally obtained” in the sense relevant to your CR 68 outcome comparison.
• Defendant’s offer amount

  • The monetary “money or property…specified in the offer” (for monetary offers, this is the offer amount).
• Costs/fee impact decision for your damages accounting

  • Even though DocketMath’s focus is a damages split, you’ll need to decide whether your “damages model” includes:

    • only damages components, or
    • also post-offer cost/fee impacts discussed under CR 68’s “costs then accrued” framework.
  • This decision affects what you label “post-offer” in your final accounting.

C. Damages and allocation inputs

• Total damages to be split

  • Example categories (whatever you used in your damages calculation): economic damages, non-economic damages, and/or other recoverable amounts.
• Accrual dates (only if you want a time-prorated split)

  • Accrual start date (e.g., injury date, breach date, or other damages-relevant date)
  • Accrual end date (often the judgment date or another cutoff matching your damages method)

D. Practical recordkeeping inputs

• Rounding/currency approach

  • DocketMath can output to cents; confirm your preferred rounding to keep the result consistent with your filings.
• Case identifiers (optional)

  • Helps you document which judgment version and which offer version the calculation corresponds to.

How the calculation works

DocketMath’s pre-post-offer-damages (US-KY) approach translates CR 68’s procedural timing trigger and offer-vs-judgment outcome framing into a practical, timeline-based split.

Step 1: Confirm the CR 68 timing window (the gate)

CR 68 provides a service/timing requirement: the offer must be served “at any time more than 10 days before the trial begins.” (Ky. R. Civ. P. 68)

So the first calculation is a date comparison:

1. Compute the days between:

   • Offer service date
   • and Trial start date
2. Determine whether the result is > 10 days.

If the offer is served 10 days or less before trial begins, the CR 68 timing gate is likely not satisfied under the default text you provided, and the intended post-offer effects you want to tie to CR 68 may not be available.

Default rule reminder: If you don’t find a claim-type-specific timing sub-rule in the CR 68 text you’re relying on, treat this as the default timing requirement.

Step 2: Set the pre-offer vs. post-offer cutoff

Once you’re applying the CR 68 timeline gate, your split cutoff is typically:

• Cutoff = offer service date

Then:

• Pre-offer period: accrual up to (but not including) the offer service date
• Post-offer period: accrual from the offer service date forward

If your damages model is not time-accruing (or you’re not modeling interest/time-based components), you can still use the cutoff as an allocation/labeling framework—but you won’t be “prorating by days” in the same way.

Step 3: Use the offer vs. final judgment comparison (outcome sensitivity)

CR 68’s structure ties post-offer consequences to whether the judgment obtained is assessed in relation to the offer—via concepts like “costs then accrued” and a “judgment finally obtained” outcome comparison (per the statute text excerpt provided).

In DocketMath’s workflow, you’ll typically align:

• Defendant’s offer amount (the specified offer number), and
• Final judgment amount (the operative judgment figure)

Practical effect on the split: depending on your intended narrative/accounting goal, the outcome comparison may determine whether you treat more of the consequences as post-offer-shift eligible (or not), even if the numeric damages total is the same.

Step 4: Compute the split amounts

You can model the split in two common ways—choose the one that matches your damages method:

If time-prorating:

1. Compute pre-offer days and post-offer days (based on your accrual start/end and the offer service cutoff).
2. Apply the ratio to the time-accrual subset of damages (not necessarily every damages category unless your model supports that).

If outcome-framing:

• Treat the “split” primarily as presentation and allocation consistent with the CR 68 gate and the offer-vs-judgment comparison—rather than a pure math prorate.

Step 5: Label the output with the Kentucky/CR 68 framing

Because this is Kentucky (US-KY), ensure your final output labels reference:

• the >10-day before trial begins timing gate under Ky. R. Civ. P. 68, and
• the rule’s connection to costs then accrued and the judgment finally obtained concept.

Common pitfalls

• Using the wrong “offer date.”
  CR 68 is triggered by when the offer is served. Use the service date from the record, not the signed date or the mailing date.

• Forgetting the “more than 10 days before trial begins” default gate.
  The statute text you provided states the default requirement. If you don’t meet it, assumptions about post-offer consequences can become unreliable.

• Mixing interim numbers with the operative final judgment.
  If there are amended judgments, remands, or post-judgment modifications, use the operative final judgment amount for the offer-vs-judgment comparison.

• Double-counting post-offer impacts.
  If your “total damages” already includes amounts you later also treat as “post-offer effects,” your post-offer figure can be inflated. Keep a clean separation between:

  • your damages model inputs, and
  • any post-offer cost/fee items you’re choosing to label separately.

• Choosing time-proration without having accrual dates.
  If you don’t have consistent accrual start/end dates, don’t force a prorated result. Use outcome-framing instead of pretending you can apportion by days.

• Overclaiming legal conclusions.
  Even if your math is correct, the question “does CR 68 apply here?” depends on factual/legal fit (service, timing, and procedural posture). Keep the calculation framed as quantification, not a determination.
