Key Takeaways
- If your policy renews in the next six months and you haven’t shopped in the last year, do it now — you’re still in the window before tariff-driven repair costs fully reprice the market.
- Full-coverage auto insurance held at $186/month in May 2026, but Insurify’s updated projection puts the 2026 full-year increase at 4% if tariff-driven parts inflation arrives as expected, up from the original 1% forecast.
- The 25% tariff on imported auto parts took effect April 3, 2025. The industry’s 12-to-18-month lag between cost shocks and filed rate changes means the pricing impact is arriving now, not last year.
- ADAS sensor recalibration now appears on 28.3% of repairable estimates and adds $350 to $500 per repair — a line item reshaping claim severity that most renewal letters won’t explain.
The calm won’t last. Full-coverage auto insurance held at $186 per month in May 2026 according to Insurify’s June rate data, effectively unchanged after months of gradual decline. That flatline looks like stability. It isn’t.
The 25% tariff on imported auto parts took effect April 3, 2025. About 6 in 10 replacement parts used in U.S. repair shops come from Mexico, Canada, and China, according to Insurify’s analysis. Those cost increases have been building in claim severity data for over a year, and the insurance industry typically takes 12 to 18 months to translate new cost structures into filed rate changes. The math on that timeline puts us squarely in the window where carriers are now sitting on a year’s worth of elevated repair data and preparing to file. The stagnation in May isn’t a plateau. It’s the last breath before the next cycle.
Insurify’s February 2026 American Driver Report had already projected a 1% national average increase for full-year 2026, putting the annual full-coverage average at $2,158, up from $2,144. That was before tariff effects fully materialized in claim data. The updated projection adds another 3 percentage points if tariff-driven repair inflation arrives as expected, pushing the 2026 increase from 1% to 4%. For a driver currently paying $186 per month, 4% is roughly $89 more per year. Not catastrophic. But it’s coming off a year when many drivers finally saw relief.
What’s Driving the Cost
The increases showing up in repair shop invoices are severity-driven, not frequency-driven. Claims frequency is roughly flat. The problem is what each claim costs, and that number has been climbing hard. Average repair costs reached $4,818 in 2025. Auto body labor rates climbed approximately 9% over the same period. Imported parts now cost more. And then there’s the ADAS factor.
Advanced driver assistance systems now require sensor recalibration on 28.3% of all repairable estimates, according to CCC’s analysis. Each calibration adds $350 to $500 per repair. That’s a line item that didn’t exist on most estimates a decade ago, and it’s showing up on more than one in four claims now. Combined with parts and labor increases, total repair costs are up roughly 14% to 16% from recent baselines. That’s the number actuaries are filing on. Not the tariff announcement. The actual claim invoices.
The Filing Lag, From the Inside
I wrote auto policies through the 2017 and 2018 hard market, when repair costs spiked after a run of large storm years. What carriers told agents about timeline was consistent: expect 12 to 18 months from the time a cost shock appears in claim data to the time it shows up in filed rates. That wasn’t carrier spin. It was accurate. The actuarial review, the state filing, the review period, the approval, the implementation lag before renewals actually cycle through, all of it takes time. What I saw then was that drivers whose policies renewed in the first wave of increases were often blindsided because the rate hike came at exactly the moment the news cycle had moved on from the underlying cause. The tariff story was big in spring 2025. The rate increases it generates will hit renewal letters in late 2026 and into 2027. Most people won’t connect the two.
On the regulatory side, there is no federal insurance regulator in this picture. Rate oversight is entirely state-level. The California Department of Insurance has not issued any public guidance on expedited review for tariff-related filings. That absence matters. Carriers in California’s review queue face the standard timeline, which under Commissioner Ricardo Lara’s tenure has included extended review periods for large personal auto rate increases. Other states with more permissive review processes will see faster pass-through in both directions.
State-Level Variation Is Significant
The national average masks a lot. Maryland and Rhode Island are the most expensive states for full coverage right now. New Hampshire remains the cheapest. Delaware has returned to the top five most expensive, displacing New York. New Jersey jumped from 15th to 6th most expensive during 2025. Washington D.C. saw an 18% increase in 2025; Rhode Island, 13%; Michigan, 12%.
On the other end, Wyoming, Iowa, and Arkansas each cut average insurance prices by more than 20% in 2025. Drivers in 39 states saw price decreases that year. Insurify projects prices will increase in 35 states and fall in 15 in 2026. That divergence tracks with how different state insurance departments have handled rate filings, faster review cycles produced faster pass-through of both increases and decreases.
For specific carriers, NJM customers are projected to see rates rise by an average of 21.18% at renewal, according to analysis from Aftermarket Matters. Erie is projected at 7.92%. Neither figure is industry-wide, but both signal that tariff-era pricing is already moving through the system for some policyholders, even as the national average looks flat.
What to Do Before Your Next Renewal
The window for favorable pricing is closing. If you’re in one of the 15 states where rates are still projected to fall, and you haven’t shopped your policy in the last 12 months, do it now. Carriers quoting today are working off loss data that predates the full tariff impact. That changes as the year-over-year claim data catches up.
Before your next renewal, check the declarations page for your coverage on rental reimbursement and parts reimbursement. When repair costs rise, carriers sometimes respond by shifting default reimbursement toward aftermarket parts rather than OEM. That change doesn’t always make the headline of the rate filing. It’s in the policy language.
Compare actual car insurance rates in your state rather than treating your current carrier’s renewal quote as the market rate, and check the best car insurance options available before that letter arrives. The $186 national average is a snapshot. The snapshot is about to change.
