Cost of living in Princeton, Kentucky

Princeton, Kentucky has about 6,241 people. That count is a 2020–2024 Census average, not a headcount from one day.

A typical home is worth about $96,600.

HUD's fair-market rent for a 2-bedroom in Caldwell County is $909 a month. That is the county number, not an apartment listing in Princeton. It runs from October 2026 through September 2027.

Kentucky's prices sit at 90.2 when the U.S. average is 100. This place is not in a metro area with its own index, so this is the state number from BEA for 2024.

Kentucky taxes wages. A typical combined sales tax is 6.0% as of January 1, 2026. That mix is statewide, not Princeton's exact store tax.

Some places in Kentucky add a local wage tax. In 2023 the state average was about 0.93% of income. That is not a Princeton bill.

In July 2026, a typical Kentucky home paid 13.81¢ per kilowatt-hour. That is a state average from EIA, not Princeton's bill.

EIA does not publish a Kentucky gasoline price. For the week of October 12, 2026, the Midwest (PADD 2) all-grades price was $4.237 a gallon. At 12,000 miles a year and 25 mpg, the index counts that as $2,033.76 a year. Those miles are our standard, not a Census figure, and every town in Kentucky shares this price.
