Loss drivers captured in the model
This calculator converts your damage estimate into a structured payout forecast. It starts with vehicle value and damage percent, then applies multipliers for flood severity, water type, electronics level, and engine exposure. These multipliers reflect how corrosion, contamination, and module failures can increase repair scope. Use the same currency code across inputs for consistent reporting.
Depreciation, betterment, and adjustments
Depreciation can be entered as a flat percent or expanded by age and mileage. The effective depreciation percent is displayed after submission so you can validate assumptions. Betterment reduces the payable damage portion when new parts improve pre-loss condition. Negotiation adjustment and claims history factor provide controlled uplift or reduction for scenario planning.
Expense add-ons and policy sublimits
Add-ons include towing, storage, rental, medical, personal items, cleaning, remediation, diagnostics, labor, and parts markup. If your policy has sublimits, you can cap major categories (admin, towing, storage, rental, medical, and items). Set a cap to a positive amount; set it to 0 for no cap. This helps model common coverage ceilings.
Repair vs total loss decision logic
You can force repair, force total loss, or let the tool auto-decide. Auto mode compares estimated loss cost to a threshold percent of vehicle value (default 75%). If total loss is used, salvage value reduces the payout when the owner retains salvage. The report also shows the applied cap base (policy limit or ACV proxy).
Outputs, charting, and exportable records
After submission, you receive a summary payout, out-of-pocket estimate, and a Plotly bar chart of major components. CSV and PDF exports mirror the on-page breakdown so you can share consistent numbers with workshops, adjusters, or internal reviewers. Use notes to document assumptions and keep versions comparable.
1) Is this a guaranteed settlement amount?
No. It is a planning estimate based on your inputs. Actual settlements depend on inspections, approved rates, documentation, and the exact wording of your coverage, exclusions, and sublimits.
2) What should I enter for damage percent?
Use a realistic percent derived from workshop quotes, inspection notes, and visible flood line evidence. If uncertain, run multiple scenarios (for example 40%, 60%, and 80%) and compare outcomes.
3) When should I use auto total-loss mode?
Use auto mode when you want the tool to switch to total loss once the estimated loss exceeds a threshold percent of vehicle value. Adjust the threshold to match your internal guideline or insurer practice.
4) How do sublimits affect results?
If a cap is set, the calculator limits that category to the cap amount before computing totals. This can materially reduce add-ons such as rental or storage when policies have strict maximums.
5) Why does water type change the estimate?
Salt and sewage exposures can accelerate corrosion and contamination, increasing the probability of wiring, sensor, and module replacement. The water type multiplier is a scenario tool to reflect that added repair scope.
6) What does GAP coverage do here?
If total loss is used and you enter a lienholder payoff, GAP can add funds up to your GAP limit to reduce any remaining payoff gap. The tool shows allocations to lienholder and owner for transparency.
