Semi-Monthly Paycheck Calculator (2026)

How the Semi-Monthly Paycheck Calculator: Take-Home Pay Works

This semi-monthly paycheck calculator shows exactly what you take home from each of your 24 paychecks a year. Enter your annual salary, filing status, state tax rate and any pre-tax deduction per paycheck, and it applies the 2026 federal tax brackets, Social Security, Medicare and your state estimate to give the gross pay, each tax and the net pay for a single semi-monthly check and for the year.

How semi-monthly pay works

Semi-monthly pay means you are paid twice a month, typically on the 15th and the last day of the month, for a total of 24 paychecks a year. It is common for salaried employees in offices, professional services and technology, and it keeps payroll aligned to the calendar, so each check covers a half month regardless of the number of workdays. When the payday falls on a weekend or holiday, employers usually pay on the previous business day.

Overtime, hours and pay dates on a semi-monthly schedule

Because a semi-monthly period does not always contain the same number of workdays, hourly employees may see differences in gross pay from one check to the next, even if their hours per week stay constant. Salaried employees receive the same amount every period, calculated as annual salary divided by 24. Semi-monthly checks are larger than biweekly checks for the same salary, but there are no three-check months. Many states require non-exempt employees to be paid at least twice a month, so semi-monthly is a common way to comply.

Worked example: $65,000 salary paid semi-monthly

A single worker earning $65,000 who takes the 2026 standard deduction has federal taxable income of $48,900 and owes about $5,620 in federal income tax. Social Security is $4,030 and Medicare is $943, so with no state tax and no pre-tax deductions net pay is about $54,408 a year. On a semi-monthly schedule that is $2,708.33 gross and about $2,266.98 net per paycheck, or 83.7% of gross pay. Add a state rate in the calculator to see the effect on each check.

Semi-Monthly take-home pay at common salaries

The estimates below use the 2026 standard deduction and federal brackets.

• $40,000 salary: gross $1,666.67 per paycheck, net about $1,430.00 per paycheck and $34,320 a year (single filer, no pre-tax deductions, no state tax).
• $55,000 salary: gross $2,291.67 per paycheck, net about $1,932.19 per paycheck and $46,373 a year (single filer, no pre-tax deductions, no state tax).
• $65,000 salary: gross $2,708.33 per paycheck, net about $2,266.98 per paycheck and $54,408 a year (single filer, no pre-tax deductions, no state tax).
• $85,000 salary: gross $3,541.67 per paycheck, net about $2,859.48 per paycheck and $68,628 a year (single filer, no pre-tax deductions, no state tax).
• $110,000 salary: gross $4,583.33 per paycheck, net about $3,592.29 per paycheck and $86,215 a year (single filer, no pre-tax deductions, no state tax).
• $150,000 salary: gross $6,250.00 per paycheck, net about $4,741.29 per paycheck and $113,791 a year (single filer, no pre-tax deductions, no state tax).

Because federal tax is progressive, the share of gross pay you keep falls slowly as salary rises. State income tax, local tax and pre-tax deductions change the numbers, so use the calculator with your own details.

Comparing semi-monthly pay with other schedules

The annual salary and annual taxes are the same no matter how often you are paid; only the size of each check changes. For a $65,000 single filer with no state tax:

• Weekly (52 checks): gross $1,250.00, net about $1,046.30 per check.
• Biweekly (26 checks): gross $2,500.00, net about $2,092.60 per check.
• Semi-monthly (24 checks): gross $2,708.33, net about $2,266.98 per check.
• Monthly (12 checks): gross $5,416.67, net about $4,533.96 per check.

Use the paycheck calculator to change the frequency, and see the biweekly vs semi-monthly pay guide for the timing differences.

Budgeting on a semi-monthly paycheck

Budgeting is straightforward: two checks a month make it easy to schedule rent or a mortgage on the first and the 15th. Because monthly bills line up with pay dates, there is no bonus month, and savings goals should be built into every check. Benefit deductions are also usually spread over 24 pay periods, which keeps them even. Compare the net amount with a biweekly schedule in the calculator to see how a change in pay frequency would affect you.

State taxes and pre-tax deductions

State income tax and pre-tax deductions reduce every semi-monthly check. States range from no wage tax to top rates above 10%, and some cities charge additional taxes. Open your state's calculator from the paycheck calculators by state hub for an accurate estimate. A traditional 401(k) contribution lowers federal income tax but not Social Security or Medicare, so each $100 per check costs less than $100 of take-home pay.

Pros and cons of semi-monthly pay

Every pay schedule involves trade-offs for employers and employees:

• Paydays match the calendar, which fits rent and mortgage schedules.
• Each check is larger than a biweekly check for the same salary.
• No three-paycheck months to track.
• Hourly workers may see checks vary because periods contain different numbers of workdays.
• Fewer checks than weekly means a longer wait between deposits.

The best schedule depends on the employer's size, industry and state law, and on your own spending pattern. If you can choose, match payday to when your biggest bills are due and automate savings on the day you are paid.

Hourly wages converted to semi-monthly pay

If you are paid by the hour, gross pay per semi-monthly check depends on hours worked. The list below assumes 40 hours a week for 52 weeks, so it averages to 86.7 hours per semi-monthly check.

• $15 an hour: $31,200 a year, or $1,300.00 gross per semi-monthly check and about $1,135.38 net (single filer, no state tax).
• $20 an hour: $41,600 a year, or $1,733.33 gross per semi-monthly check and about $1,483.57 net (single filer, no state tax).
• $25 an hour: $52,000 a year, or $2,166.67 gross per semi-monthly check and about $1,831.75 net (single filer, no state tax).
• $30 an hour: $62,400 a year, or $2,600.00 gross per semi-monthly check and about $2,179.93 net (single filer, no state tax).
• $40 an hour: $83,200 a year, or $3,466.67 gross per semi-monthly check and about $2,806.72 net (single filer, no state tax).
• $50 an hour: $104,000 a year, or $4,333.33 gross per semi-monthly check and about $3,416.42 net (single filer, no state tax).

Use the hourly paycheck calculator to include overtime and your state tax, and the hourly to salary calculator to convert wages without tax.

When will my first semi-monthly paycheck arrive?

Expect your first semi-monthly paycheck by the next 15th or last day of the month, depending on when you start and the payroll cutoff. Some employers pay in arrears, so the check may cover the previous half-month. Ask HR for the payroll calendar so you can plan around the first deposit. Then review the stub for the right pay rate, hours, deductions and tax lines, and correct any mistake in writing right away. Our guide to reading a paycheck stub and the abbreviations glossary can help you interpret each line.

Semimonthly versus biweekly: the key difference

Semimonthly pay delivers exactly 24 paychecks a year, typically on fixed dates like the 1st and 15th, or the 15th and last day of the month. This differs from biweekly pay, which delivers 26 paychecks tied to a fixed weekday, meaning semimonthly paychecks are usually slightly larger since the same annual salary is divided across fewer pay periods.

Semimonthly pay periods aren't all the same length: a period covering the 1st through the 15th typically has 15 days, while the second half of the month has 13 to 16 days depending on the month, which is why hourly employees on semimonthly pay may notice slightly different amounts even when they work a consistent schedule.

Why semimonthly pay complicates benefit deductions

Many recurring benefit deductions, like health insurance premiums, are set as a flat per-paycheck amount rather than a daily rate, so with only 24 paychecks a year on semimonthly pay, each deduction is proportionally larger than it would be spread across 26 biweekly paychecks.

This is worth checking carefully if you're comparing job offers with different pay frequencies, since the same total annual premium cost can look different per-paycheck depending on whether you're being paid semimonthly or biweekly, even though your true annual cost is the same.

Common mistakes on a semi-monthly schedule

• Budgeting from gross pay. Use net pay per check.
• Forgetting the number of checks. You are paid 24 times a year.
• Ignoring withholding. Review your W-4 with the W-4 calculator.
• Skipping state tax. It can take 3% to 8% of each check.
• Assuming pay dates never change. Holidays can move payday.

Key takeaways

• A semi-monthly schedule pays 24 times per year.
• Annual taxes do not change with pay frequency.
• A $65,000 single filer nets about $2,266.98 per check before state tax.
• Pre-tax deductions lower income tax but not FICA.
• Compare frequencies with the calculator before choosing a budget.
