Formula Used
Base Labor = Labor Hours × Labor Rate Paint Cost = Paint Area × Paint Rate Frame Cost = Frame Hours × Frame Rate Panel Prep Cost = Damaged Panels × Panel Prep Cost Adjusted Labor = Base Labor × Damage Multiplier × Vehicle Multiplier Adjusted Parts = Parts Cost × (1 + Parts Markup ÷ 100) Subtotal = Adjusted Labor + Paint Cost + Adjusted Parts + Materials + Frame Cost + Panel Prep + Diagnostic Fee Tax = Subtotal × Tax Rate ÷ 100 Total Estimate = Subtotal + Tax Low Estimate = Total Estimate × 0.90 High Estimate = Total Estimate × 1.18 Impact Speed m/s = Impact Speed mph × 0.44704 Impact Energy = 0.5 × Vehicle Mass × Speed² Average Impact Force = Impact Energy ÷ Crush Distance
The physics section gives a simplified collision estimate. Real repair prices depend on teardown findings, part availability, shop rates, paint matching, sensors, calibration, and hidden structural damage.

Auto Body Repair Estimate Guide
Why Repair Estimates Vary
Auto body repair pricing changes from one vehicle to another. A small dent can be simple. A hidden bracket can make the job harder. Modern vehicles also use sensors, cameras, radar units, and special materials. These items increase the final bill. This calculator gives a structured estimate before a shop visit.
Labor And Damage Level
Labor is often the largest cost. Shops charge by the hour. Heavy damage needs more removal, measuring, straightening, sanding, and fitting. The calculator applies a damage multiplier. Light damage has a lower factor. Severe damage has a higher factor. This helps the estimate follow the repair effort.
Paint And Materials
Paint work includes surface prep, primer, color coat, clear coat, masking, blending, and polishing. Large panels need more material. Pearl and metallic colors may cost more. Paint rates in this tool are entered by square foot. You can change the rate to match your local market.
Parts And Markup
Replacement parts can include bumpers, lights, grilles, brackets, fenders, clips, and trim pieces. Shops may add markup to cover sourcing, handling, warranty risk, and ordering time. The calculator lets you enter a parts markup percentage. This gives a more realistic total.
Physics Based Insight
The physics part uses kinetic energy. It estimates the energy involved in a collision. It also estimates average impact force through crush distance. This does not replace a frame inspection. It helps explain why higher speed damage can become expensive quickly.
Use As A Planning Tool
Use this calculator for budgeting, comparison, and early planning. It can help before insurance claims, private repair decisions, or shop discussions. Always confirm the result with a trained technician. Real damage often appears after teardown. Calibration and safety checks may also be needed.
Frequently Asked Questions
1. Is this repair estimate final?
No. It is a planning estimate. A shop may find hidden damage after removing panels, trim, bumper covers, lights, or interior parts.
2. Why does vehicle type change the cost?
Different vehicles use different materials, parts, sensors, and repair methods. Luxury, electric, and large vehicles often need more time and cost.
3. What is impact energy?
Impact energy is the kinetic energy linked with vehicle mass and speed. Higher speed increases energy strongly because speed is squared.
4. Does the calculator include insurance deductibles?
No. It estimates repair cost only. You can compare the result with your deductible, claim rules, and insurer guidance separately.
5. What is a damage multiplier?
It adjusts labor and related costs based on repair difficulty. Severe damage usually needs more measuring, straightening, fitting, and refinishing.
6. Why is paint area important?
Paint area affects material use, masking time, blending work, and finish labor. Larger areas usually increase both material and labor needs.
7. Can I use this for frame damage?
Yes, for a rough estimate. Enter frame hours and frame rate. A real frame inspection is still needed for safety.
8. Why do parts have markup?
Shops may add markup for ordering, handling, warranty risk, storage, and sourcing delays. You can set markup to zero if needed.
