Frequently Asked Questions
Why is a semi-monthly paycheck larger than a biweekly paycheck?
A semi-monthly schedule distributes your salary across 24 paychecks per year, while biweekly distributes it across 26 paychecks. Therefore, each semi-monthly check is approximately 8.3% larger, but you receive two fewer paychecks over the year.
Which schedule is easier for personal household budgeting?
Semi-monthly aligns directly with monthly fixed expenses like rent, mortgages, and utility bills because pay dates occur at predictable calendar dates every month.
