Plano costs about 16% more day to day, but Plano has no state income tax while Kentucky does — which can reverse the comparison once you look at take-home rather than sticker prices.
Housing does most of the damage
Housing is the reason two metros differ at all. Everything else — groceries, a haircut, a phone plan — varies far less than rent does. A one-bedroom runs about $1,050 a month in Louisville and $1,450 in Plano — $400 a month apart, or $4,800 a year.
If you plan to buy rather than rent, the numbers move further apart: median prices of $255,000 and $490,000 mean a difference of about $47,000 in up-front cash at 20% down, plus whatever the property tax spread between Kentucky and Texas adds annually.
The price-to-rent ratios diverge enough to change the buy-versus-rent answer: about 20 in Louisville versus 28 in Plano. Under about 15 the math favours owning; over about 20 it favours renting and putting the down payment to work elsewhere. Which means the right answer can genuinely be to buy in one and rent in the other.
Taxes the index leaves out
Income tax is the variable the index ignores, and here it is decisive: Texas charges none while Kentucky does. Budget $4,000–$8,000 a year of difference on a $100,000 salary before comparing rents.
The offset is rarely free, though. States without an income tax usually recover it elsewhere — property tax rates in Texas and sales tax are the usual places to look. If you plan to buy rather than rent, run the property tax number before assuming the no-income-tax state is cheaper.
There is a city-level tax to account for as well: Louisville charges about 2.20% local income tax, while Plano charges none. On $100,000 that is roughly $2,200 a year, deducted before you ever see it and easy to miss when comparing two offers.
Getting around
Louisville is effectively car-dependent; Plano is served by limited transit.
Work, weather, and what else is different
Louisville is a mid-size metro of about 1.4M and roughly flat; Plano is a major metro of about 8.1M and growing steadily.
Both metros have real employment in healthcare, which matters if you want to move without changing careers — your experience is legible to employers in both. Louisville also leans on logistics/air cargo and bourbon & food manufacturing, with employers like UPS (Worldport hub) and Ford. Plano leans on corporate headquarters (telecom, finance, tech), with Toyota Motor North America (HQ) and JPMorgan Chase (regional hub).
Climate belongs in the comparison, not as a footnote. Louisville: Humid continental climate: January lows near 28°F, July highs near 89°F with high humidity. Plano: Humid subtropical climate: January lows near 35°F, July highs near 96°F, humid.
Louisville Metro levies a ~2.2% occupational license (payroll) tax on wages, stacked on top of Kentucky's flat state income tax; UPS's Worldport air hub drives large overnight-shift employment. No state or local income tax; Toyota's 2017 relocation of its North American headquarters to Plano was part of a broader wave of major corporate HQ moves into the Dallas-Fort Worth area.
The index behind the headline ratio is BEA Regional Price Parity data; rents and home prices are market figures, and tax rates are as published by each state and city. How these are compiled and updated.
