How do I convert an hourly wage to an annual salary?

Multiply your hourly rate by the hours you work per week, then by the weeks you work per year. For full-time work that is usually hourly rate × 40 × 52, so $25 an hour becomes $52,000 a year gross before taxes.

What is the Missouri state income tax rate?

Missouri uses a graduated income tax with a top marginal rate around 4.7% as of 2025, applied above a small exempt amount. This tool uses an effective Missouri rate to approximate state withholding on your salary.

What taxes are deducted from a Missouri paycheck?

Federal income tax, Missouri state income tax, and FICA (6.2% Social Security plus 1.45% Medicare) come out of your gross pay. Some Missouri cities like St. Louis and Kansas City also levy a 1% earnings tax that this tool can include.

Does this account for the St. Louis or Kansas City earnings tax?

Yes, optionally. St. Louis and Kansas City impose a 1% local earnings tax on residents and people who work there. Toggle the local tax option if you live or work in one of those cities to see a more accurate net pay.

Is this my exact paycheck?

It is a close estimate using flat effective rates. Your actual paycheck depends on W-4 allowances, pre-tax 401(k) and health contributions, and exact tax brackets, so treat the result as a planning figure rather than payroll-exact.

Switching between an hourly rate and an annual salary is the first step in understanding a job offer — but the number that really matters is what lands in your bank account. This calculator converts your hourly wage to a gross annual salary, then estimates your Missouri take-home pay after federal tax, Missouri state income tax, and FICA.

How it works

Gross salary comes from your rate, hours, and weeks. Net pay subtracts the major payroll taxes:

gross annual = hourly rate × hours/week × weeks/year
federal tax  = gross × effective federal rate
state tax    = gross × Missouri effective rate (~4.7% top)
FICA         = gross × 7.65%  (6.2% SS + 1.45% Medicare)
local tax    = gross × 1%  (St. Louis / Kansas City only)
net pay      = gross - federal - state - FICA - local

Example

$25/hour, 40 hours/week, 52 weeks:

gross   = 25 × 40 × 52 = $52,000
FICA    = 52,000 × 0.0765 = $3,978
state   = 52,000 × 0.047  = $2,444  (approx)

Tips and notes

FICA is a flat 7.65% on most wages, so it is the most predictable deduction. Federal tax is progressive — this tool uses an effective rate, so very high or very low earners should adjust it. If you live or work in St. Louis or Kansas City, enable the 1% local earnings tax for a more accurate net figure. Pre-tax 401(k) or health contributions, not modeled here, will further lower your taxable pay.
