How to use our Car Crash Settlement Estimate Calculator
- Pick an Estimation method: Multiplier, Per-diem, or Show both to compare.
- Enter your documented money losses: Past medical bills (USD), Estimated future medical costs (USD), Past lost wages (USD), Estimated future lost earnings (USD), Property damage (USD), and Other out-of-pocket costs (USD).
- For multiplier estimates, choose Injury severity (for multiplier method). If you choose Custom multiplier, enter your number in Custom multiplier (number).
- For per-diem estimates, enter Per-diem rate (USD per day) and Per-diem days (days) (count of days with meaningful symptoms or limits).
- Enter Your share of fault (percent) from 0 to 100. This reduces the estimate by that percent.
- If you know them, enter At-fault bodily injury policy limit (USD) and At-fault property damage policy limit (USD) to see how low limits can cap what is realistically collectible.
- Open Advanced options if you want to (a) choose what the multiplier is based on, (b) enter a Low multiplier and High multiplier range, or (c) estimate optional deductions like Known liens or repayments (USD), Attorney fee (percent, if applicable), and Case costs (USD).
- Click Calculate and read results in order: Economic damages total (your receipts), then pain and suffering, then the gross value, then the fault-adjusted value, then the policy-limited collectible estimate.
- Sanity-check: if the policy-limited result is much lower than the gross value, the usual causes are (1) non-zero fault percent, (2) a low bodily injury limit or property damage limit, or (3) you picked a pain base that is smaller than you expected.
Definitions
Economic damages total (USD): Money losses you can add up with receipts or records, like medical bills, lost income, property damage, and other crash costs.
Non-economic damages (pain and suffering): Hard-to-measure harms like physical pain, discomfort, stress, and loss of enjoyment that do not come with a bill.
Multiplier method: A common estimating approach where pain and suffering is calculated as a multiplier times a chosen cost base (set in Advanced options).
Per-diem method: A common estimating approach where pain and suffering is a daily dollar amount times the number of days you had meaningful symptoms or limits.
Estimated gross case value (before fault and policy limits) (USD): Economic damages plus the selected pain and suffering estimate, before any reductions.
Your share of fault (percent): The percent of responsibility assigned to you; this tool reduces the estimate by that percent as simple math (rules vary by state).
Policy limit (bodily injury / property damage): The maximum a liability insurance policy will pay for injury-related losses (BI) or property damage (PD) under that policy, if those limits apply to the claim.
Estimated net to you (optional) (USD): The policy-limited estimate minus optional deductions you enter (liens/repayments, attorney fee, and case costs). Negative means your entered deductions are larger than the estimated collectible amount.
Common mistakes and quick fixes
Mistake: Mixing categories, like putting car repair or towing into a medical or wage field.
Fix: Put vehicle repair or replacement in Property damage (USD) , and put towing, rental, parking, and supplies in Other out-of-pocket costs (USD) .
Mistake: Choosing a per-diem method but leaving Per-diem rate or Per-diem days blank (or typing a weekly/monthly number into the days box).
Fix: Check Estimation method and then recalculate. Enter a dollars-per-day rate and a true day count (for example, 12 weeks is about 84 days).
Mistake: Entering a custom multiplier but not selecting Custom multiplier under injury severity (so your custom number is ignored).
Fix: Check Estimation method and then recalculate. Set Injury severity to Custom multiplier if you want the calculator to use your custom value.
Mistake: Entering only Low multiplier or only High multiplier and expecting a range output.
Fix: Check Estimation method and then recalculate. Enter both numbers, keep them greater than 0, and make sure high is greater than or equal to low.
Mistake: Using the other driver's fault percent instead of Your share of fault (percent) (example: typing 80 when you mean you were 20% at fault).
Fix: Enter your own share from 0 to 100. If you were 20% at fault, type 20.
Mistake: Thinking the gross value is what you will collect, even when insurance limits are low or unknown.
Fix: Check Estimation method and then recalculate. If you know policy limits, enter them to see the cap. If you do not know them, treat the gross value as a what-if estimate, not a guaranteed payout.
Limitations & Key Assumptions / Boundary Conditions
This calculator is an estimate tool, not legal advice, not a court award, and not an insurance company offer. Real outcomes depend on evidence, medical records, credibility, negotiation, and the rules in your state.
Pain and suffering is not a receipt-based number. The multiplier and per-diem methods are simple estimating frameworks and can be far from real settlement results.
The default severity multipliers (minor 1.5, moderate 2.5, severe 4.0) are internal starting points so the calculator can run without extra inputs. They are not legal standards, and you should adjust them if they do not fit your situation.
The policy limit step is simplified. It treats property damage as separate and applies a bodily injury cap to the remaining injury-related value. Real cases can involve multiple vehicles, multiple injured people, multiple policies, uninsured/underinsured coverage, umbrella coverage, disputes about what coverage applies, or collectible money beyond insurance.
The fault adjustment is straight percent reduction. Some states use modified comparative negligence rules that can reduce or block recovery above certain fault levels; this calculator does not apply state-specific cutoffs.
Optional net-to-you results depend entirely on what you type for liens/repayments, attorney fees, and case costs. This tool cannot tell whether a lien is valid, negotiable, or even applies, and it cannot estimate taxes or unpaid bills you did not include.
Methodology
1) Add economic damages. Economic damages are your money losses. The calculator totals the six USD fields you enter.
economic_total = medical_past + medical_future + lost_wages_past + lost_earnings_future + property_damage + other_costs
2) Estimate pain and suffering (non-economic damages). You can use a multiplier method, a per-diem method, or show both side-by-side.
pain_per_diem = per_diem_rate * per_diem_days
Multiplier method details. First the calculator picks a pain base (the number being multiplied). This is controlled by the Advanced option that tells the calculator what costs pain and suffering should be based on.
pain_base = (medical_past + medical_future) OR (medical_past + medical_future + lost_wages_past + lost_earnings_future) OR economic_total
Next it picks a multiplier. If you choose a severity level, the default mapping is minor 1.5, moderate 2.5, severe 4.0. If you choose Custom, it uses your custom multiplier. If you enter both a low and high multiplier, the calculator shows a range for the multiplier method.
pain_mult_single = pain_base * m_single
pain_mult_range = [pain_base * multiplier_low, pain_base * multiplier_high]
3) Compute gross case value (before fault and policy limits).
gross = economic_total + pain_estimate
4) Reduce for your share of fault.
fault_adjusted = gross * (1 - fault_percent/100)
5) Apply policy limits (if provided). This tool caps injury-related value using the bodily injury limit and caps the property damage amount using the property damage limit. If you leave a limit blank, that cap is skipped.
injury_part = fault_adjusted - property_damage
injury_capped = min(injury_part, policy_limit_bi) if policy_limit_bi provided
property_capped = min(property_damage, policy_limit_pd) if policy_limit_pd provided
policy_limited = max(0, injury_capped) + max(0, property_capped)
6) Optional net-to-you estimate (only if you fill in any deductions). If you enter liens/repayments, attorney fee percent, or case costs, the calculator subtracts them from the policy-limited estimate. Negative results are allowed and mean your entered deductions are larger than the estimated collectible amount.
net_to_you = policy_limited - liens_and_repayment - case_costs - (policy_limited * attorney_fee_percent/100)
Worked mini-example (multiplier method). Past medical 12,000; future medical 3,000; past lost wages 2,000; future lost earnings 0; property damage 3,500; other costs 300.
economic_total = 12,000 + 3,000 + 2,000 + 0 + 3,500 + 300 = 20,800
If pain base is medical plus wage losses, then pain_base = 12,000 + 3,000 + 2,000 + 0 = 17,000. With moderate severity (multiplier 2.5), pain and suffering = 17,000 * 2.5 = 42,500. Gross = 20,800 + 42,500 = 63,300. With 0% fault, fault_adjusted = 63,300.
