Total Loss or Repair? Do the Math First

A worked example, not just the general rule.

Everyone knows the general rule — if repair costs exceed roughly 70-80% of your car's value, insurance calls it a total loss. But the decision that actually matters is often yours: whether to accept a total-loss settlement or ask to retain and repair the vehicle. Here's the actual math, worked through with a real example, so you can make the call with numbers instead of a gut feeling.

The three numbers you need

1) Actual Cash Value (ACV): what your car was worth immediately before the crash, based on comparable sales. 2) Repair estimate: the written, itemized cost to restore the vehicle. 3) Salvage value: what a salvage buyer would pay for the damaged vehicle. Insurance total-loss math is essentially: if repair estimate > ACV × threshold (commonly 70-80%, varies by insurer), it's declared a total loss.

Worked example

Say your car's ACV is $18,000 and your insurer's total-loss threshold is 75%. The threshold dollar amount is $13,500. If your repair estimate comes in at $12,000, the insurer repairs it. If it comes in at $15,000, it's declared a total loss — you'd receive roughly $18,000 minus your deductible (or minus salvage value if you keep the car), rather than a $15,000 repair.

When keeping and repairing a 'totaled' car makes sense

If you retain the vehicle, your payout is ACV minus salvage value minus deductible, and the title becomes a salvage or rebuilt-salvage title. If you can get an honest, itemized repair quote below that adjusted payout, and you're comfortable with a salvage title's resale impact, repairing can leave you with a functioning car and cash left over. This math only works with a legitimate, thorough estimate — go in with real numbers, not a guess.

Where diminished value fits into the decision

Even a perfectly repaired car (not totaled) loses resale value simply from having an accident on record. In Maryland, you may be able to claim diminished value from an at-fault driver's insurer separately from your repair costs — factor this into whether repair is truly the better financial outcome versus a clean total-loss payout.

Get real numbers before you decide

Before accepting either outcome, get a written, itemized estimate from a shop you trust — not just the insurer's internal number. A thorough estimate that documents hidden damage protects you either way: it gives you an accurate repair cost if you're fixing it, and it can support a higher ACV negotiation if you're not.

Frequently asked questions

Should I fix my car or let insurance total it?

Compare your realistic repair cost to your retain-and-repair payout (ACV minus salvage value minus deductible). If a trustworthy shop's estimate comes in below that adjusted payout and you're fine with a salvage title, repairing can be the better financial move. If not, taking the total-loss settlement is usually cleaner.

What percentage of value makes a car a total loss in Maryland?

There's no single state-mandated percentage — it varies by insurer, commonly falling in the 70-80% range of the vehicle's actual cash value. Some carriers use different formulas, so ask your specific insurer for their threshold.

Can I keep my car if it's declared a total loss?

Usually yes, through an owner-retention settlement. You receive ACV minus salvage value and minus your deductible, keep the vehicle, and the title is rebranded salvage. Maryland's MVA has a specific process for re-titling and re-inspecting rebuilt vehicles.

Is a salvage title a big deal if I'm keeping the car long-term?

For a car you plan to drive for years and not resell, a salvage title matters less day-to-day, though it can affect insurance options and resale value significantly if you do sell later.

Does diminished value factor into the repair-vs-total decision?

It can. Even a fully repaired car loses some resale value from having an accident on record — in Maryland you may be able to recover that separately from an at-fault driver's insurer, which changes the total financial picture if you choose to repair.
