This semi-monthly pay calculator converts your hourly wage into semi-monthly paychecks along with daily, weekly, monthly, and yearly breakdowns. If you're paid twice a month and want to know exactly what each paycheck should look like — or you're trying to figure out how an hourly rate translates to a semi-monthly schedule — this tool does the math instantly.
Enter your hourly rate, hours per week, and days per week, and you'll see your earnings broken down across every common pay period. It's especially useful if you're switching from hourly to salaried pay, comparing job offers with different pay frequencies, or budgeting around a semi-monthly payroll schedule.
What Is Semi-Monthly Pay?
Semi-monthly pay means you receive a paycheck twice per month — typically on the 1st and 15th, or the 15th and last day of the month. That gives you exactly 24 paychecks per year, regardless of how many weeks are in a given month.
This is different from biweekly pay, where you're paid every two weeks and receive 26 paychecks per year. The distinction matters more than most people realize because it affects your per-paycheck amount and how you budget month to month.
With semi-monthly pay, your paycheck amount stays consistent every month since each month always has exactly two pay dates. This predictability makes it easier to align your paychecks with monthly bills like rent, mortgage payments, and subscriptions.
How Semi-Monthly Pay Is Calculated
The formula for calculating semi-monthly pay from an hourly wage involves a few simple steps:
Step 1: Calculate your annual salary
Annual Salary = Hourly Wage × Hours per Week × 52
For example, at $25/hour working 40 hours per week: $25 × 40 × 52 = $52,000 per year
Step 2: Divide by 24 pay periods
Semi-Monthly Pay = Annual Salary ÷ 24
$52,000 ÷ 24 = $2,166.67 per paycheck
That's your gross (pre-tax) semi-monthly paycheck amount.
The calculator also shows your earnings in other intervals using these formulas:
- Daily Wage = Hourly Wage × Hours per Day
- Weekly Wage = Hourly Wage × Hours per Week
- Monthly Wage = Annual Salary ÷ 12
- Yearly Wage = Hourly Wage × Hours per Week × 52
How to Use This Calculator
- Enter your hourly wage — Type in your hourly rate. If you're evaluating a job offer, use the offered rate.
- Set your hours per week — The default is 40 hours (standard full-time). Adjust this if you work part-time or regularly put in more hours.
- Set your days per week — The default is 5 days. Change this for compressed schedules like four 10-hour days.
- Read your semi-monthly pay — The highlighted result shows your semi-monthly paycheck amount. You'll also see daily, weekly, monthly, and yearly breakdowns for the complete picture.
Semi-Monthly Pay for Common Hourly Rates
This table shows semi-monthly paycheck amounts based on a 40-hour work week:
Hourly Rate | Semi-Monthly Pay | Monthly Pay | Annual Salary |
|---|---|---|---|
$12.00 | $1,040.00 | $2,080.00 | $24,960 |
$15.00 | $1,300.00 | $2,600.00 | $31,200 |
$18.00 | $1,560.00 | $3,120.00 | $37,440 |
$20.00 | $1,733.33 | $3,466.67 | $41,600 |
$22.00 | $1,906.67 | $3,813.33 | $45,760 |
$25.00 | $2,166.67 | $4,333.33 | $52,000 |
$30.00 | $2,600.00 | $5,200.00 | $62,400 |
$35.00 | $3,033.33 | $6,066.67 | $72,800 |
$40.00 | $3,466.67 | $6,933.33 | $83,200 |
$50.00 | $4,333.33 | $8,666.67 | $104,000 |
A quick mental shortcut: multiply your hourly rate by 86.67 to get your approximate semi-monthly paycheck. So $20/hour × 86.67 ≈ $1,733 per paycheck.
Semi-Monthly vs. Biweekly Pay: What's the Difference?
These two pay schedules sound similar but work differently, and mixing them up can throw off your budgeting.
Semi-monthly pay gives you 24 paychecks per year, paid on fixed dates each month (like the 1st and 15th). Each paycheck is slightly larger because there are fewer of them.
Biweekly pay gives you 26 paychecks per year, paid every 14 days. Each paycheck is slightly smaller, but you get two "extra" paychecks compared to semi-monthly. In two months of the year, you'll receive three paychecks instead of two.
Here's how the same $52,000 annual salary breaks down:
Pay Schedule | Paychecks per Year | Amount per Paycheck |
|---|---|---|
Semi-Monthly | 24 | $2,166.67 |
Biweekly | 26 | $2,000.00 |
Monthly | 12 | $4,333.33 |
Weekly | 52 | $1,000.00 |
The annual total is identical — only the per-paycheck amount and timing differ. Semi-monthly is popular with employers because it simplifies benefit deductions (exactly two per month), while biweekly is common because it aligns neatly with two-week work periods.
Why Semi-Monthly Pay Matters for Budgeting
Semi-monthly paychecks align naturally with how most bills work. Rent, mortgage, car payments, insurance premiums, and most subscriptions are billed monthly. When you receive two consistent paychecks per month, it's straightforward to assign one paycheck to cover certain bills and the other to cover the rest.
For example, with a semi-monthly paycheck of $2,167 (based on $25/hour full-time):
- 1st paycheck (received on the 1st): covers rent/mortgage, car payment, utilities
- 2nd paycheck (received on the 15th): covers groceries, insurance, savings, discretionary spending
This kind of split becomes harder with biweekly pay because the pay dates shift each month, and two months out of the year you get a third paycheck that can disrupt your routine.
What to Keep in Mind
These are gross earnings. The amounts shown are before federal and state income taxes, Social Security (6.2%), Medicare (1.45%), and any other deductions. Your actual take-home semi-monthly paycheck will be lower. As a rough guide, most workers take home about 70-80% of their gross pay, depending on their tax bracket and deductions.
Hours matter. If you don't consistently work the same hours every week — maybe you pick up extra shifts some weeks or get sent home early others — your actual semi-monthly earnings will vary from the calculated amount.
Overtime changes the math. If you regularly work more than 40 hours per week, your overtime hours (typically paid at 1.5× your regular rate) will increase your semi-monthly pay beyond what this calculator shows at your base rate.
Part-time adjustments. The calculator works just as well for part-time schedules. Just enter your actual hours per week. Working 25 hours per week at $20/hour gives you a semi-monthly paycheck of $1,083.33 rather than the full-time $1,733.33.
