Example data table

Formula used

This tool estimates an annual premium using a transparent, adjustable model:

• Base premium = base_rate_per_$1k × (vehicle_value ÷ 1,000)
• Liability component scales with selected limits versus a baseline.
• Collision & comprehensive are % of vehicle value, adjusted by deductible.
• Add-ons (PIP, UM, MedPay, rental, roadside) use fixed loads scaled by limits.
• Total premium = (sum of components) × risk_factors × discount_factors

Risk factors include age, mileage, location, driving record, and insurance score where permitted.

How to use this calculator

Insights

Premium drivers in one view

This tool combines vehicle value, exposure, and selected coverages to estimate an annual premium. In the example table, moving from a $8,500 car to a $32,000 car raises the estimate by about $1,540 per year because physical damage coverages scale with value. Multipliers reflect age, miles, location, and driving record. Components are summed, then adjusted by risk and discounts.

Deductibles and out of pocket risk

Deductibles reduce collision and comprehensive costs through a deductible factor. For many profiles, moving from $500 to $1,000 can lower those portions by roughly 10% to 20%, but it increases what you pay after a claim. The suggested deductible uses your emergency fund to keep out of pocket risk manageable. Pair a higher deductible with a plan to replenish savings within six months.

Liability limits and asset protection

Liability is priced separately and scaled by selected limits versus a 50/100/50 baseline. A planning benchmark is 100k/300k/100k, while higher mileage or heavy commuting can justify 250k/500k/100k. Because liability losses can exceed vehicle value, limit choices often matter more than deductible tweaks. Use the tool to compare how upgrading property damage from 50k to 100k shifts the liability factor and total premium.

Add ons that change the curve

Optional protections add smaller, more predictable loads. PIP, uninsured motorist, medical payments, rental reimbursement, and roadside assistance can reduce disruption costs after a crash, theft, or breakdown. Keep rental per day realistic, because higher daily limits increase the add on linearly in the estimate. When you disable collision or comprehensive, the graph will flatten and totals will drop, but repair risk shifts to you.

Using results to refine choices

After you calculate, review the premium breakdown and the deductible sensitivity graph. If the curve is steep, physical damage costs dominate and a higher deductible may help. If it is flat, liability and risk factors drive cost, so confirm mileage, adjust limits, and consider discounts. Save scenarios as CSV or PDF. Recheck after major changes.

FAQs

What does the premium estimate represent?

It is a planning estimate created from your inputs, coverage selections, and risk multipliers. It is not a quote, and it may differ from insurer pricing, discounts, and underwriting rules.

Should liability limits be higher than the car value?

Often yes. Liability pays for injuries and damage you cause to others, which can exceed the value of your vehicle. Higher limits may better protect savings and future income.

When does it make sense to drop collision or comprehensive?

If the car is older and low value, the premium savings may outweigh expected claim benefits. If you have a loan or lease, dropping these coverages may violate requirements.

How should I choose a deductible?

Pick a deductible you could pay without hardship. A higher deductible can reduce premiums, but it increases out-of-pocket cost during a claim. Use your emergency fund as the main guide.

Why do mileage and driving record affect cost so much?

More miles generally means more time on the road and higher crash exposure. Tickets and prior claims increase expected loss frequency, so insurers typically charge more for those profiles.

How can I use the exports effectively?

Run several scenarios, then download CSV or PDF for side-by-side comparisons. Save one version for renewal planning and another for shopping different limit and deductible combinations.
