What does adding a newly licensed driver cost?
In the Massachusetts Division of Insurance’s own example household, adding a driver licensed one year raises the filed premium from about 32% at one carrier to about 118% at another.
The source
Where the number comes from
Every private-passenger auto rate filing submitted to the Massachusetts Division of Insurance has to include premiums for the same set of standardized example households. Two of them differ in exactly one way. One has two experienced drivers and two cars. The other is that same household with a third driver added: licensed one year, driving occasionally.
Set a carrier’s filed premium for the household with the added driver against its premium for the household without, and the difference is what that carrier’s filing says the driver adds. We read that difference, as a percentage, for each major carrier whose filing we could compare on these two examples, in every town its filing lists, and took the middle one: the typical town. The filings took effect between March 2024 and August 2026.
These are percentage changes in carriers’ filed examples, not a price for any household. No real family matches the example exactly, and a percentage says nothing about the dollars a household starts from.

What it means for your household
Carriers weigh the same driver very differently.
The added driver is the same at every carrier. What differs is how each one weighs a newly licensed driver. In a filed example, the same added driver raises the premium by about a third at one carrier and more than doubles it at another. The Division’s example defines this driver by years licensed, not age, so a teen is the common case, not the only one.
Your carrier’s answer is one answer among many.
If your current carrier tells you what adding your teen will do to your premium, that is one answer from one carrier. The filings show how far apart the answers can run. We can’t tell you where yours falls without looking at your household, and a percentage from a filing is not a number to expect for yourself.
Start with your current carrier, then get on the list.
Talk to your current carrier before the license date and ask what adding the driver will do to your premium. We can’t place policies before January. If a closing or renewal can’t wait, handle it with your current carrier for now, tell us the date, and your household goes first when we open. When your turn comes, the review runs overnight, covers everything you hold, the new driver included, and tells you plainly whether to switch or stay. More on this moment on the Teen Driver page.
The wider reading
This is one of four findings. Carriers also disagree about what experience is worth, about which towns cost more, and about what a home policy changes on the auto side.
Figures above are read directly from each carrier’s own rate filings with the Massachusetts Division of Insurance, against the Division’s own standardized example households. They describe how each carrier’s filed rate structure behaves, not any real household’s price, and are not an offer or estimate for any individual. We read the major carriers’ filings closely enough to set them side by side; together they write most of the private-passenger auto insurance in Massachusetts, out of roughly three dozen carriers. More are added as their filings are read.
