: Ads on phones, a faster home page and a link to ClickyTools
Phones now see the Adsterra native banner as well as the slim A-ADS one, and calculator, state and guide pages carry up to three clearly labeled "Sponsored" banners (two on a phone). The home page loads faster on phones: the Google tag waits until the page has loaded, the home banners no longer move the page when they appear, and the heaviest hero effects now run only on wide screens. The "Previous" button under the calculator list now matches its spoken name, and the footer underlines its links. The footer and the calculator list also link to ClickyTools, a companion site with more free utility tools.
: New home page, ads strip and a new hourly pay video
The home page has a new look: a moving hero, a looping strip of calculators, four "what do you want to work out" tiles with small animations, and calculators and guides in pages of nine and six. It also carries three clearly labeled "Sponsored" banners: a slim A-ADS banner above the introduction (written into the page itself so the network can verify it), an Adsterra banner right under it and an Adsterra native banner between the calculators and the states (a phone gets only the slim A-ADS one). Ads never float or cover the page, stay out of the lists and policy pages, and are not shown to visitors in Europe or with a privacy signal. The privacy policy was updated to say where ads appear. We also made a 30-second video that shows how the Hourly to Salary Calculator turns $25 an hour into a yearly salary and take-home pay.
: Six new guides
New guides on how gross pay turns into take-home pay, what a move to a state with no income tax really saves, how credit card interest works, the new federal tips and overtime deductions, the state payroll programs that take a share of pay (disability, paid leave and long-term care) and where a $60,000 salary goes furthest.

: Six new calculators
New calculators for the salary you need to take home a set amount, for comparing two states, for how much house you can afford, for refinancing a mortgage, for paying off a credit card and for the new federal deductions for tips and overtime. Each one has a worked example, its formula, its assumptions and its sources, and is tested against independent calculations.

: State paycheck pages use official pay and rent data
Every state page now shows median earnings, rent, home values and property tax from the U.S. Census Bureau (2024 American Community Survey), the median pay of 12 common jobs from the Bureau of Labor Statistics (May 2025), the salary needed to take home $2,500 to $10,000 a month, where the state ranks among the 51, and the 2026 payroll programs that take a share of pay in 15 states (such as California SDI and Washington Paid Leave), taken from each state’s own agency. The page title now starts with the state name and the words salary calculator.
: Hourly to Salary calculator shows take-home pay
Choose a state and filing status to see take-home pay after federal, state and FICA tax, next to the yearly, monthly and weekly pay. The page also has a table of what $25 an hour takes home in ten states.
- Hourly to Salary Calculator: Turn an hourly wage into yearly pay, or a salary into an hourly rate.
: Guides link to the new calculators
Six existing guides now point to the matching new calculator: how much house you can afford, the refinance break-even point, credit card minimum payments, understanding your paycheck, take-home pay by state and how to calculate overtime pay.

: Hourly pay tables and city taxes on state pages
Each state page has a table of $15 to $50 an hour with take-home pay and an answer to how much tax is taken out of a paycheck. The pages for Pennsylvania, New York, Michigan, Missouri, Ohio, Colorado and Oregon list city taxes (Philadelphia, New York City, Detroit, St. Louis, Kansas City, Columbus, Denver and Portland) with official rates. The FICA calculator page lists the Social Security wage base for 2021 to 2027, and the auto loan calculator has a field for title, registration and dealer fees.
: Bonus tax and 15 vs 30 year mortgage calculators
Two new calculators: how much of a bonus you keep after federal, state and FICA tax, and the interest and payment difference between a 15-year and a 30-year mortgage.

- 15 vs 30 Year Mortgage Calculator: Compare the payment, interest and balance of a 15-year and a 30-year mortgage.
: Figures re-checked against their sources
The 2026 state and local tax deduction cap ($40,400), the FDIC national savings and CD rates and the average Social Security retirement benefit were compared with the agencies’ own pages, and the guides that quoted older figures were corrected. Each guide now shows one review date.
: FICA tax and overtime calculators
Two new calculators: Social Security and Medicare tax for employees and the self-employed, and overtime pay with the rule for pay that raises the regular rate.
- FICA Tax Calculator: See your Social Security and Medicare tax, and what your employer adds.
- Overtime Pay Calculator: Work out your overtime pay and your total pay for the week.
: State pages: minimum wage, overtime and payday rules
Every state page lists the minimum wage, overtime rules and payday rules from the U.S. Department of Labor, and what changed on January 1, 2026 from the Tax Foundation. All 50 states and Washington, DC are open to search engines.
: Guides reviewed against official sources
Every guide was checked claim by claim against official sources and now lists them. Fourteen new guides and an Emergency Fund calculator were added, and every calculator page has a methodology and sources section.
: Paycheck calculators for every state
Paycheck calculators for the 50 states and Washington, DC, built on the 2026 state tax tables, were added in daily batches. All guides were rewritten in plain English, and every calculator page got a worked example.
Every calculator and guide also shows its own review date. See the editorial policy for how pages are reviewed and kept up to date.
