Kansas and Oklahoma at a glance
Moving between Kansas and Oklahoma changes more than the scenery. On a $60,000 salary, Kansas leaves $28,860 a year after taxes, rent, food, energy and gasoline; Oklahoma leaves $30,369.
Oklahoma comes out ahead by $1,509 a year ($126 a month). The calculation starts from the same gross pay in both states, subtracts federal tax, Social Security and Medicare, then each state's own income tax, and then the population-weighted cost of a one-bedroom rental, groceries, home energy and gasoline across 2,947,197 people in 105 counties in Kansas and 4,028,634 people in 77 counties in Oklahoma.
Taxes: what each paycheck loses
Federal income tax ($5,072) and FICA ($4,590) on $60,000 are the same on both sides of the border. State income tax takes $2,548 in Kansas and $2,312 in Oklahoma, which leaves take-home pay of $47,790 and $48,026.
At $100,000
At $100,000 take-home pay is $74,121 in Kansas and $74,689 in Oklahoma, a difference of $568. The gap widens with income because graduated state brackets take a growing share.
Living costs
One-bedroom rent averages $1,004 a month in Kansas and $914 in Oklahoma, so Oklahoma is $90 a month cheaper for housing. Food costs $3,436 a year in both, because the USDA Thrifty Food Plan is a national figure; home energy $2,011 and $1,845, and gasoline $1,436 and $1,406. Together the basics cost $18,931 a year in Kansas and $17,658 in Oklahoma.
What the Census adds
Median household income is $74,275 in Kansas and $65,039 in Oklahoma. Homeowners pay a median of $2,798 a year in property tax in Kansas and $1,599 in Oklahoma. Commuters travel 19.7 minutes each way on average in Kansas and 22.4 in Oklahoma.
Method
Taxes use the 2025 rules for a single filer with wage income only and the standard deduction. Housing and living costs are county figures from HUD (one-bedroom Fair Market Rent), the USDA Thrifty Food Plan and state energy prices from the Energy Information Administration, averaged across each state's counties and weighted by population, so large counties count more. Local income taxes are not included. Counties differ widely inside every state, so use the county pages for a specific place.
