Formula Used
Base compensation rate: Average Weekly Wage × 66.6667%.
Scenario cap: The base rate is compared with the selected state wage cap. This page uses 82.5% of SAWW for a basic 1x scenario and 110% of SAWW for higher multiplier testing.
Disability rating: AMA impairment rating × grid factor.
Weekly PPD estimate: Capped compensation rate × disability rating × multiplier.
Final weekly estimate: Weekly PPD estimate after final caps, safety penalty, and extra adjustment.
Gross value: Final weekly estimate × benefit weeks.
Present value: Weekly payment stream discounted by the entered annual discount rate.
Net estimate: Present value minus prior paid credit and estimated attorney fee.
How to Use This Calculator
Enter the average weekly wage first. Then add the state average weekly wage for the injury year.
Enter the medical impairment rating as a percentage. Choose automatic grid factor mode for a quick estimate.
Use manual grid mode only when you already know the correct factor from a worksheet or case review.
Select the multiplier that matches the scenario you want to test. Add benefit weeks if you do not want automatic duration.
Enter safety penalties, discounts, credits, or estimated fees when needed. Press the calculate button.
The result appears above the form and below the header. Use the CSV and PDF buttons to save the estimate.
Kentucky PPD Planning Guide
What the Estimate Reviews
A Kentucky PPD estimate starts with average weekly wage, or AWW. This wage is usually compared with state limits for the injury year. The calculator lets you enter both numbers, so old and new claims can be reviewed in one place. It then applies the impairment rating assigned by a qualified medical evaluator.
Why the Grid Factor Matters
The impairment rating does not stand alone. Kentucky claims often use a grid factor. The grid factor converts medical impairment into a disability rating. The tool can select a common factor from the rating range, or you can enter your own value when a claim worksheet uses a different factor.
Testing Different Scenarios
Multipliers are also important. A basic scenario may use one times the weekly amount. Other scenarios may test a higher multiplier when work ability, job duties, or wage return issues are being reviewed. The calculator also includes a safety penalty field, a discount rate field, prior paid benefits, and an attorney fee estimate.
Reading the Result
Results appear after submission. The weekly rate, disability rating, benefit weeks, gross value, present value, prior credit, fee estimate, and net estimate are displayed together. This makes comparisons easier for claimants, adjusters, paralegals, and content teams building public estimate tools.
Important Limits
This page is designed as an estimator. It does not replace the official worksheet, legal advice, medical evaluation, or current agency guidance. Kentucky workers' compensation rules can depend on injury date, statutory caps, return to work facts, education, age, exclusions, settlements, and disputed evidence. Always verify important numbers before using them in a demand, settlement memo, or case filing.
Saving Reports
The export buttons help keep records clean. Download the CSV file for spreadsheet review. Download the PDF report for printing or sharing. The example table below the form shows typical input patterns, so new users can understand how each field affects the estimate.
Comparison Method
For better testing, run several scenarios. Change only one field at a time. Compare a one times case, a three times case, and a capped case. Save each result separately. This method shows which assumption drives the award most. It also helps explain the estimate to a client or reviewer without hiding the math. Use reliable records for wage and medical details.
FAQs
What does KY PPD mean?
KY PPD usually means Kentucky Permanent Partial Disability. It refers to a workers' compensation benefit estimate for a partial lasting impairment after a workplace injury.
Is this calculator an official result?
No. This tool gives an estimate only. Official values can depend on statutes, injury date, medical proof, caps, multipliers, credits, and legal findings.
What is average weekly wage?
Average weekly wage is the worker's wage figure used for benefit calculations. It is often based on earnings before the injury.
What is an impairment rating?
An impairment rating is a medical percentage assigned for lasting loss of function. The calculator uses it as a main input.
What is the grid factor?
The grid factor adjusts the impairment rating into a disability rating. Use auto mode for estimates or manual mode for known worksheet values.
Why does the multiplier change the result?
The multiplier tests different benefit scenarios. A higher multiplier can increase the weekly estimate, subject to caps and other limits.
Can I download the result?
Yes. After calculating, use the CSV button for spreadsheet data or the PDF button for a printable summary report.
Should I use this for settlement decisions?
Use it for planning only. Confirm important numbers with current law, official worksheets, medical records, and qualified legal guidance.
