Biweekly Pay Calculator

What This Biweekly Pay Calculator Does

Biweekly pay — being paid every two weeks, resulting in 26 paychecks per year — is the most common pay schedule in the United States. This calculator converts either an annual salary or an hourly rate into your exact biweekly paycheck amount, both gross (before taxes) and net (take-home), using 2026 federal tax brackets, an estimated state tax rate, and standard FICA payroll tax rates.

Whether you're evaluating a new job offer quoted as an annual salary, converting your hourly wage into a predictable biweekly figure for budgeting, or just double-checking that your paystub matches what you expect, this calculator handles both input directions and shows the full breakdown of what's deducted from each check.

How It Works

If you enter an annual salary, the calculator divides it by 26 to get your gross biweekly pay, then calculates federal tax (using the full annual amount run through 2026 brackets and divided back to a per-check figure), an estimated state tax, and FICA — all scaled to the biweekly period. If you enter an hourly rate and weekly hours instead, it first multiplies your rate by your weekly hours by 52 weeks to get an annual equivalent, then runs the same tax calculation from there.

This dual-input approach reflects how biweekly pay actually works in practice: salaried employees think in annual terms, while hourly employees think in terms of rate and hours — but both ultimately need to know the same thing: what will actually be in the next paycheck.

Formula & Methodology

Gross Biweekly Pay = Annual Salary ÷ 26

Or, for hourly employees: Annual Equivalent = Hourly Rate × Weekly Hours × 52

Net Biweekly Pay = (Annual Salary − Annual Federal Tax − Annual State Tax − Annual FICA) ÷ 26

Federal tax is calculated on your full annual income using 2026 projected brackets and your filing status's standard deduction, then divided by 26 to match your pay schedule. FICA applies 6.2% Social Security (capped at the $176,100 annual wage base for 2026 projections) and 1.45% Medicare (uncapped) to your gross wages.

Tips & Best Practices

• Know your "three-paycheck months" — because 26 biweekly pay periods don't divide evenly into 12 months, two months each year will have three paychecks instead of the usual two. Planning for these extra checks (rather than treating them as bonus spending money) is a powerful budgeting habit.
• Don't confuse biweekly with semi-monthly — biweekly is every two weeks (26 checks/year, varying calendar dates); semi-monthly is twice a month on fixed dates like the 1st and 15th (always 24 checks/year). They produce different per-check amounts even for the same annual salary.
• Budget off your smallest expected month — if you build your monthly budget assuming a three-paycheck month, you'll come up short in the ten months that only have two.
• Recalculate whenever your hourly hours change — if you're hourly and your schedule varies, your biweekly gross will fluctuate; use your typical or average weekly hours for the most realistic annual projection.

Biweekly Pay and Monthly Budgeting

The trickiest part of managing biweekly pay is that it doesn't align neatly with the monthly bills most households pay — rent, mortgage, and many subscriptions are due once a month, but biweekly paychecks arrive on a rolling two-week cycle that shifts slightly each pay period. In a typical month, you'll receive two paychecks; in the two "extra" months per year, you'll receive three. Many financial planners recommend building your baseline monthly budget using only the two-paycheck months as your assumption, then treating any third paycheck in a given month as a bonus opportunity to pay down debt, build savings, or cover an irregular expense — rather than baking it into your regular monthly spending plan.

Because the specific months that get a third paycheck shift depending on your employer's exact pay calendar start date, it's worth mapping out your own pay dates for the full year in a calendar or budgeting app so you know exactly which months to expect the extra check.

Converting Between Pay Frequencies

If you're comparing a job offer that pays biweekly against one that pays semi-monthly or monthly, remember that the per-check amount alone doesn't tell you which pays more — you need to compare annualized totals. A semi-monthly job paying $2,708 per check ($65,000 ÷ 24) might look larger than a biweekly job paying $2,500 per check ($65,000 ÷ 26), but if both are based on the same $65,000 annual salary, they're financially identical over the full year — just distributed differently.

Common Mistakes

• Assuming 24 biweekly paychecks instead of 26. Some people mentally default to "twice a month" when they hear biweekly, but biweekly means every two weeks — 26 times a year, not 24.
• Forgetting the occasional 27-paycheck year. Due to how 26 two-week periods align with the calendar, certain years produce a 27th paycheck depending on your specific pay calendar start date. This is uncommon but worth checking with your HR department if your dates seem off.
• Not accounting for the Social Security wage base on high incomes. If your annual salary is well above $176,100, your Social Security withholding will stop once you hit that cap partway through the year, making later paychecks slightly larger.
• Using this calculator for semi-monthly pay by mistake. If your pay stub shows exactly 24 payments per year on fixed calendar dates, you're on a semi-monthly schedule, not biweekly — the per-check math is different.
