Semi-monthly vs biweekly pay calculator
Semi monthly meaning
Semi-monthly means twice a month: 24 paychecks a year, usually on fixed dates such as the 15th and the last day of the month (or the 1st and 15th). Biweekly means every two weeks: 26 paychecks a year, always on the same weekday. The annual salary is the same; only the size and timing of each check change.
Semi monthly pay vs biweekly pay
On a $60,000 salary, a semi-monthly paycheck is $2,500.00 gross and a biweekly paycheck is $2,307.69. Single in Texas, take-home is about $2,099.58 per semi-monthly check or $1,938.08 per biweekly check, $50,390 a year either way after 2026 federal tax and FICA.
Semi monthly paycheck: the two 3-paycheck months
Because 26 biweekly paydays don't divide evenly into 12 months, two months a year usually have three paychecks. With paydays every other Friday starting January 2, 2026, the extra checks land in January and July. Semi-monthly pay never has a 3-check month, so monthly bills line up more neatly; biweekly gives you two "bonus" checks if you budget on two per month.
Semi monthly payroll and biweekly payroll calculator
For employers, semi-monthly payroll means 24 runs a year and pay dates that move around the week; biweekly payroll means 26 runs on a fixed weekday. Hourly employees are usually paid biweekly because overtime is figured by workweek, which semi-monthly periods split. The employer cost per check above adds the employer's 6.2% Social Security (up to $184,500 of wages) and 1.45% Medicare.
Semi monthly salary and net salary
To convert: semi-monthly pay = annual salary ÷ 24, biweekly pay = annual salary ÷ 26, and hourly pay = annual salary ÷ 2,080. Net salary is what's left after federal and state income tax, Social Security, Medicare and pre-tax deductions such as 401(k); the calculator spreads each year's 2026 tax evenly across your checks, so actual withholding can differ by a few dollars.
