How to calculate take-home pay by hand
Gross pay, minus pre-tax items, minus Social Security and Medicare, minus federal income tax, minus state tax, minus anything taken after tax. Worked on a $52,000 salary in Pennsylvania, the pencil lands on $1,581.72, the same cents as the calculator.
Step 1: the gross check
$52,000 a year, divided by 26 paychecks, is $2,000.00. That is gross pay: the offer letter, cut into slices. Paid weekly, divide by 52; twice a month, by 24; monthly, by 12. Paid by the hour, multiply the rate by the hours instead, with overtime hours at their higher rate. Every line below starts from this number, so if it is wrong, everything is.
Step 2: subtract pre-tax items first
This stub has a $60 health insurance premium taken through a workplace cafeteria plan. $2,000.00 minus $60.00 is $1,940.00. That is the wage the taxes below are measured on, which is why pre-tax items lower tax: they shrink the number the tax is built on.
One catch. A traditional 401(k) lowers the wages for federal income tax, but Social Security and Medicare still count it. A cafeteria-plan premium lowers all three. If you have both, keep two wage figures.
Step 3: Social Security and Medicare
Social Security is 6.2% and Medicare is 1.45%, 7.65% together. $1,940.00 × 6.2% = $120.28. $1,940.00 × 1.45% = $28.13. Social Security only applies up to the 2026 wage base of $184,500 per employer, which this check never approaches. Medicare has no cap; an extra 0.9% starts after $200,000 of wages from one employer.
Step 4: federal income tax, annualized
Federal withholding under IRS Publication 15-T rests on one idea: pretend this paycheck repeats all year. Brackets are yearly, so first make a yearly number. $1,940.00 × 26 = $50,440.00.
Then take off the standard deduction, $16,100.00 for a single filer with nothing else on the W-4, leaving $34,340.00 of taxable income. Publication 15-T splits that deduction differently: Worksheet 1A subtracts $8,600.00 on line 1g (to $41,840.00), and its tax table charges nothing on the first $7,500.00. The two pieces add up to the same $16,100.00, so the arithmetic lands in the same place.
Step 5: walk the brackets
The first $12,400.00 of taxable income is taxed at 10%: $1,240.00. Only the slice above it is taxed at 12%: $34,340.00 minus $12,400.00 leaves $21,940.00, and 12% of that is $2,632.80.
Add the slices: $3,872.80 for the year. Divide by 26, and federal income tax is $148.95 a paycheck. The calculator’s federal line says $148.95. The full 2026 bracket table is on the 2026 federal tax brackets page.
Step 6: state tax
Every state has its own rulebook. Texas and Florida have no wage tax; others use brackets, their own deductions or a flat rate. Pennsylvania is a flat 3.07% of compensation with no standard deduction. $1,940.00 × 3.07% = $59.56.
Pennsylvania also withholds an employee unemployment contribution: 0.07% of wages for 2026, with no wage cap. On this check that is $1.36. Most Pennsylvania municipalities add a local earned income tax as well, which this example leaves out. Your state revenue department publishes its own formula; the Pennsylvania paycheck calculator and every other state page show the line with its source.
Step 7: after-tax items, then the bottom line
Last, anything taken after tax: a Roth 401(k), a garnishment, union dues, some voluntary benefits. This stub has none. When you do have them, they come off the very end and change none of the taxes above.
Now subtract. $2,000.00 minus $60.00, $120.28, $28.13, $148.95, $59.56 and $1.36 is $1,581.72. The calculator’s net pay for the same inputs is $1,581.72. Over a year the engine’s total is $41,124.82, 79% of gross. The video for this page stopped one line early, at $1,583.08; the Pennsylvania unemployment line is the $1.36 difference.
Where hand math usually goes wrong
The wrong number of pay periods, such as 24 instead of 26. Treating every pre-tax item as if it lowered every tax. Using the top bracket as a flat rate on the whole check. Forgetting the W-4 entries: a Step 3 credit, the Step 2 checkbox or extra withholding in Step 4(c) all change the federal line. How to fill out a W-4 shows each one.
Some payroll systems use the wage-bracket tables instead of the percentage formula, so a few cents can differ, and the take-home pay calculator shows each line with its source if you want to compare. Treat hand math as an estimate; the stub is the number that counts. This is not tax advice.

Questions
What is the formula for take-home pay?
Gross pay minus pre-tax deductions, minus Social Security and Medicare, minus federal income tax, minus state and local tax, minus after-tax deductions.
How do I calculate federal withholding by hand?
Annualize the taxable wage (multiply by pay periods), subtract the standard deduction, apply the 2026 brackets slice by slice, then divide by the pay periods. Adjust for any W-4 entries.
Do pre-tax deductions lower Social Security and Medicare?
Cafeteria-plan items such as health premiums do. A traditional 401(k) lowers only federal income tax (and some state taxes).
Why is my hand math a few cents off the stub?
Rounding, a wage-bracket table instead of the formula, or a small line such as a state unemployment or local tax. Compare one line at a time.
