Biweekly vs. Semimonthly Pay: Which Budget Template Fits?
Biweekly means every two weeks. Semimonthly means twice a month. They can look similar on a bank statement, but the dates follow different rules. A paycheck budget should use the schedule you actually receive.
Compare the schedules
| Question | Biweekly | Semimonthly |
|---|---|---|
| What repeats? | A 14-day interval | Two pay dates each month |
| Example dates | March 6, March 20, April 3 | March 15, March 31, April 15 |
| Is the gap always 14 days? | Yes, for the unadjusted schedule | No; it depends on the dates and month |
| Usual annual pay periods | 26; some calendars have 27 | 24 |
These dates illustrate the schedules, not a specific employer’s payroll. ADP explains the distinction between biweekly and semimonthly pay. Confirm your actual pay dates with your employer, including any holiday adjustments.
See why the date matters for a bill
Suppose a $1,000 bill is due April 1. On the example biweekly schedule, March 20 is the last payday before the bill; April 3 is too late to fund a payment due April 1 from that new paycheck. On the example semimonthly schedule, March 31 falls before the due date.
The bill amount is identical, but the paycheck that arrives before it changes. Check when funds become available and when a payment must clear. A spreadsheet does not change those dates or pay the bill.
Use the Biweekly Budget for every-14-day pay
Sheetlark’s free Biweekly Budget template for Google Sheets is designed for pay arriving every 14 days. In your own copy:
- Read Start Here and try Example before adding your information.
- Enter your first payday and take-home pay in the indicated yellow input cells.
- Add the bill amounts and due dates, plus your living and savings reserve.
- Check the generated dates in Paychecks against your actual payroll calendar.
- Review the projected closing balances in Overview and Dashboard.
The workbook’s rolling 365-day planning range includes 27 payday dates. This is its planning capacity, not a claim that every calendar year contains 27 payments. Do not replace a twice-monthly schedule with generated 14-day dates just to make it fit.
Use a monthly view when that is the question
If you need to compare category budgets with the month’s actual spending, use Monthly Budget. It summarizes the month; it is not a semimonthly paycheck allocator and does not assign a bill to a particular twice-monthly paycheck.
Keep your actual pay dates available when timing matters. At present, Sheetlark does not offer a dedicated semimonthly paycheck workbook. Choose a monthly summary only when that matches the task you want to do.
Check a projected shortfall
A negative projected balance shows that the entered income, reserves and bills do not fit within that period. Check your inputs before relying on the plan. It does not provide money, move a due date or connect to your bank.
