Diminished Value Calculator (Formula Comparison)
Compare illustrative diminished-value calculations, their assumptions and the high-mileage cutoff.
JusticeFinder Tool
Loss-of-Use & Rental Reimbursement Calculator
Compare rental days and daily cost with entered daily, total-dollar and covered-day limits. See the amount within those caps and the remaining difference, without treating either as approved coverage or a payment owed.
Compare rental costs and coverage caps
Enter a quote or receipt and the limits you want to compare. The results update as you edit; eligibility and payment are assessed separately.
How to use this tool
- Open the calculator. Scroll to the interactive tool section and review the starter inputs already filled in as educational examples.
- Enter documented numbers. Replace sample bills, wages, rates, fault share, or care costs with values you can support with records.
- Compare the live results. Read each result card and its formula notes separately. These educational calculations are not a settlement range or a prediction of what an insurer or court will pay.
- Save and keep documenting. Copy or print the estimate, open a linked spreadsheet if available, then pair the output with related guides before any insurer negotiation.

What this comparison can tell you
Use this tool to compare a rental quote or receipt against limits you enter. It can help you spot a daily-rate shortfall, a dollar cap or days beyond a selected limit before discussing the bill. If you have no rental receipt, an assumed daily rate still produces arithmetic, but it does not establish a loss-of-use claim or a reimbursement benefit.
Keep a record of where each input came from. Use the rental dates and rate from the bill or quote, and check the policy, endorsement and written authorization for limits. The calculator assumes the entered rate and selected days qualify; it does not decide coverage, liability or reasonableness. Taxes, extra fees, deductibles, waiting periods and payments already received are not calculated.
Formula and zero-value settings
- Entered total = days × daily rental rate.
- Days used for the cap comparison = the smaller of entered days and the covered-day limit. A zero day limit applies no additional day cap.
- Amount within caps = the smaller daily rate or daily allowance, multiplied by those days, then limited by the overall dollar cap. A $0 daily cap means $0 allowance. A zero overall cap applies no additional dollar limit.
- Difference = entered total minus amount within caps. Selecting No sets the within-caps amount to zero. A difference is not a finding that someone owes it; zero does not confirm approval or payment.
Zero total/day limits are modeling settings, not proof your policy is unlimited. Do not leave an unknown cap at zero and treat the output as confirmed coverage. Use Reset example to restore the sample inputs; it does not clear a claim record.
Worked example: 12 days at $45
The sample total is 12 × $45 = $540. With a $30 daily cap, a $900 overall cap and no additional day limit, $360 fits within the caps and $180 remains outside them. This illustrates the formula; it is not a typical settlement or a predicted payment.
Set the covered-day limit to 10: $30 × 10 = $300 fits, leaving $240. Keep 10 days and lower the overall cap to $200: only $200 fits, leaving $340. Raising a daily allowance above the actual rate cannot increase the comparison beyond the entered rental cost.
Repairs, total loss and follow-up records
The scenario buttons change the records reminder, not the formula. For repairs, record shop entry, completion, parts delays and any rental extension request. For a total loss, keep valuation and settlement notices alongside the rental authorization and its end date. Do not use the scenario button as approval for every day until you buy another vehicle.
Texas example: the Texas Department of Insurance explains that rental payments are subject to a reasonable period and daily/overall dollar limits. Its guide also warns that rental payments may end shortly after a total-loss notice. This Texas guidance is not a nationwide eligibility rule. Read the TDI auto insurance guide.
Before relying on the comparison, ask which expenses and dates were accepted, which cap or exclusion applies, and whether the amount discussed is an estimate, authorization or payment. Keep the written answer with receipts. A disagreement about eligibility or a claim without a rental requires a separate review of the applicable policy, facts and state law.

Frequently Asked Questions
Does the difference show what another insurer owes?
No. It is the entered rental total minus the amount that fits within your selected caps. It does not determine fault, coverage, liability, legal entitlement or an actual payment.
What if I never rented a car?
An assumed daily rate can show a comparison, but the calculator cannot establish eligibility for a claim without rental receipts. Review the applicable policy, facts and state law separately before treating a figure as recoverable.
What do zero coverage caps mean?
A zero daily cap means a $0 daily allowance. A zero overall dollar cap or covered-day limit means no additional limit of that kind is entered. These model settings do not prove unlimited coverage. Confirm unknown limits before relying on a result.
Does Total loss automatically allow more rental days?
No. The scenario changes the records reminder only. Enter the dates and limits you want to compare, and separately check the rental authorization and its end date.
Can I compare a daily cap and a maximum number of days?
Yes. Enter both limits and any overall dollar cap. For 12 days at $45 with a $30 daily cap and a 10-day limit, $300 fits before any lower overall cap, leaving a $240 difference from the $540 entered total.
Educational Use Disclaimer
This calculator is an educational property-damage estimate only and does not constitute legal advice. Loss-of-use entitlement, reasonable rates, and the number of compensable days vary by policy language and state law.
