Check a car repair estimate

How to get a car repair estimate.

A car repair estimate is the shop's statement of the work it proposes and what it expects to charge. Ask for it in writing before any work starts, and ask that it say the shop will contact you for approval before doing work beyond it.

Some states go further. California requires repair dealers to give a written estimated price for parts and labor for a specific job, and Michigan requires a written estimate that itemizes parts and labor as closely as possible before repair work begins. Rules differ from state to state.

If the shop has to inspect or diagnose the car before it can write the estimate, ask what that step will cost and whether the charge is credited toward the repair.

A calculator for the estimate you already have.

Many online car repair estimate calculators predict a price from a vehicle and a location. This page does something different: it takes the numbers written on your estimate, adds them up to the cent, keeps an unknown line unknown and compares two estimates side by side.

It is free, needs no account and keeps what you enter in this browser. It is not estimating software for repair shops, and it does not replace the written estimate itself.

How to read a car repair estimate, line by line.

Read the estimate as a set of separate decisions rather than one number. Each line should tell you what is done, to which part, with what, and for how much. The abbreviations are explained in the glossary below.

• The header: shop name and contact details, your vehicle and its mileage, the date, and how long the estimate stays valid.
• The problem and the cause: what you reported, what the shop found and how it found it.
• Parts: each part named, with its quantity, its price and its type (new from the vehicle maker, aftermarket, used or rebuilt).
• Labor: each operation with its hours and the hourly rate, or a flat charge for the operation.
• Sublet: work the shop sends to another business, such as an alignment, glass or machine-shop work.
• Fees: shop supplies, environmental or disposal fees, diagnostic charges and any core charge, each named.
• Tax and the total, and whether the total is a fixed amount or a range.
• Approval and warranty: how extra work will be approved, and the written warranty on parts and labor.

Red flags on a car repair estimate.

• Only a total, with no parts or labor listed.
• A part listed without saying whether it is new, aftermarket, used or rebuilt.
• Vague lines such as miscellaneous or labor as needed, or a large supplies charge with no explanation.
• Work you did not ask about, with no explanation of why it is needed now.
• No statement that the shop will ask for your approval before going beyond the estimate.
• Pressure to approve on the spot, or a refusal to put the estimate in writing.
• No written warranty terms.

Why two estimates for the same repair differ.

Scope explains most of the gap: one estimate may include related parts, fluids or a follow-up check that the other leaves out, or may fix a different cause of the same problem.

The rest usually comes from the parts type, the number of labor hours and how they were set, the hourly rate, the fees, sublet work and the warranty offered. A lower total can describe a smaller job.

How to compare two car repair estimates.

• Check that both estimates fix the same problem with the same operations before looking at the totals.
• Compare the parts type part by part: new from the maker, aftermarket, used or rebuilt.
• Compare labor as hours and hourly rate separately, not only as a dollar amount.
• Put fees, tax and sublet work side by side: one estimate may include what the other leaves out.
• Compare the written warranties on parts and on labor.
• Use Compare two at the top of this page: both estimates are laid out line by line, and the lower total is not labeled better.

When a second estimate is worth it.

• The estimate is a single total with no breakdown.
• The cause of the problem is not written down, or the shop cannot explain how it found it.
• Several expensive items are recommended at once and none is explained.
• The job is large compared with what the car is worth to you.
• The shop adds work during the repair that was not written down and approved.

If the car has a safety problem, such as braking, steering or a warning light that stays on, have it checked before driving it to another shop.

What is the $3000 rule for car repairs?

It is a popular rule of thumb, not a standard: no government agency, insurer or industry body sets it, and people state it in different ways. The shared idea is to pause before approving a large repair and weigh it against the car's value, its condition and what else it is likely to need.

A rule of thumb cannot know your car. The repair-or-replace model in the list below compares keeping the car with replacing it, using only the amounts you enter.

Is $100 an hour fair for mechanic labor?

RepairWorth cannot tell you whether a given hourly rate is fair. It has no licensed data on U.S. shop labor rates, and rates vary with the region, the type of shop and the kind of work.

What you can check is how the labor line is built: the hourly rate, the hours for each operation and where those hours come from. Ask each shop for both in writing, then compare hours with hours and rate with rate. Technician wage statistics are not the rate a shop bills, so they are not a benchmark either.

How much does it typically cost to repair a car?

No single figure fits your car: the price depends on the job, the vehicle, the parts chosen, the shop and where you live. Published averages describe a particular sample, such as one kind of repair or one group of vehicles, and are not the price of your repair.

The most reliable number is a written estimate for your vehicle; for a larger job, get two and compare them line by line. For a specific job, the pages listed below by system explain what a complete estimate for that work should contain.

Car repair estimate laws by state.

Checked on September 23, 2026. Method: each state’s statutes and regulations were searched on its official legislature or agency site, then each row was checked against the text of the law, on the official site or, where it could not be read, on a public legal mirror that reproduces it.

This is not legal advice; local ordinances and later amendments are not covered; check the linked text. Each row summarizes the law, and a dash means the checked text gave no value for that column.
