Boston-Cambridge-Newton, MA-NH metro area · August 2026 · delivery-platform prices

These are delivery-platform prices. This metro doesn't yet have enough in-store observations to publish a shelf series, so the figures below come from our separately-labeled marketplace series. Delivery listings carry platform markups, so treat the level as a delivery price — never compare it to a shelf price from another market. Month-over-month changes remain valid, because a roughly constant markup cancels out when the same item at the same store is compared to itself. Why we publish both.

The line stops at the break on purpose. From August 2026 the item median is taken over distinct prices rather than every reading, so the index restarts at 100 instead of chaining through July — the step across that gap would measure the change of method, not a change in prices.

Grocery prices in Boston, MA — common questions

Are grocery prices going up in Boston, MA?

The GroceryChop Price Index tracked 563 grocery delivery-platform prices across 23 stores in Boston, MA in August 2026, for a weighted basket cost of $4.87. We publish no month-over-month change for August 2026: from this month the item median is taken over distinct prices rather than every reading, so August is not comparable with July and the index restarts at 100. A comparable change will publish for September 2026.

How much do groceries cost in Boston, MA?

The weighted basket cost — the average unit price of a basket of everyday staples — was $4.87 in August 2026. This is a comparative measure, not a typical weekly grocery bill, and level comparisons between markets are indicative rather than precise because the mix of items clearing our sample thresholds differs by market. The month-over-month change is the like-for-like figure.

Where does GroceryChop's Boston, MA price data come from?

From 23 grocery stores across 7 banners in the Boston-Cambridge-Newton, MA-NH metro area, observed directly rather than surveyed.
