People type this into search every day: weekly pay to annual salary.
The usual answer is “multiply by 52.” That is the right first move. It still needs the period count, because a $2,400 check is not the same year if it lands every two weeks or twice a month.
This page is a labeled conversion. It is not a tax return, and it is not personalized financial advice.
The IRS counts the periods, then annualizes
IRS Publication 15-T Table 3 is the payroll conversion table. Line 1b asks how many pay periods you have per year. Line 1c multiplies this period’s wages by that count.
The 2026 table uses these counts:
- weekly: 52
- biweekly: 26
- semimonthly: 24
- monthly: 12
- quarterly: 4
- daily: 260
Publication 15 section 8 calls a payroll period “a period of service for which you usually pay wages.” Withhold for that period even if the employee did not work every day of it.
The pay period converter does the same multiply, then splits the year:
pay per period × periods per year
Monthly is that annual figure divided by 12. Weekly is the annual figure divided by 52. Hourly is the weekly figure divided by the hours you type. Every period is treated as the same gross amount. The hourly line uses 52 weeks. Those are the tool’s assumptions.
Fig 1
One check, then the year
The period count is the only multiplier that matters
Gross pay times the IRS period count is the year. Month, week, and hour are that year split again.
The result is gross pay. Deductions, overtime, and unpaid weeks stay out unless you already baked them into the check you typed.
Example 1: the published $2,400 biweekly check
Here are the calculator defaults:
- gross pay per period: $2,400
- pay periods per year: 26
- average hours per week: 40
Annual: 2400 × 26 = $62,400.00
Per month: 62400 ÷ 12 = $5,200.00
Per week: 62400 ÷ 52 = $1,200.00
Per hour: 1200 ÷ 40 = $30.00

One week
$1,200.00
The year is $62,400.00 of the same $2,400 check.
A 40-hour week inside that year is $1,200.00, which is $30.00 an hour.
Example 2: the same year, paid every week
Keep the $62,400 year. Pay it weekly.
- gross pay per period: $1,200
- pay periods per year: 52
- hours per week: 40
Annual: 1200 × 52 = $62,400.00
Month, week, and hour print the same $5,200.00, $1,200.00, and $30.00.

Example 3: twice a month is 24, not 26
Semimonthly pay lands on two calendar dates, often the 15th and the last day. IRS Table 3 counts 24 of those.
- gross pay per period: $2,600
- pay periods per year: 24
- hours per week: 40
Annual: 2600 × 24 = $62,400.00
The month is still $5,200.00. Each check is $200 larger than the biweekly $2,400 because you get two fewer checks.
Example 4: one monthly paycheck
- gross pay per period: $5,200
- pay periods per year: 12
- hours per week: 40
Annual: 5200 × 12 = $62,400.00
Week and hour stay $1,200.00 and $30.00.

| Category | Check | Annual |
|---|---|---|
| Weekly | $1.2k | $62k |
| Biweekly | $2.4k | $62k |
| Semimonthly | $2.6k | $62k |
| Monthly | $5.2k | $62k |
Weekly is 52 checks of $1,200. Biweekly is 26 checks of $2,400.
Semimonthly is 24 checks of $2,600. Monthly is 12 checks of $5,200.
Example 5: daily pay uses 260
Publication 15-T also lists a daily count of 260. That is 52 weeks times 5 weekdays.
- gross pay per period: $240
- pay periods per year: 260
- hours per week: 40
Annual: 240 × 260 = $62,400.00
Hourly is still $30.00. 240 ÷ 8 = 30 if a workday is one fifth of 40 hours.
Example 6: a $800 week
Not every week is $1,200.
- gross pay per period: $800
- pay periods per year: 52
- hours per week: 40
Annual: 800 × 52 = $41,600.00
Per month: $3,466.67
Per hour: $20.00

Example 7: $18 an hour, 40 hours
Start from the hourly rate and go the other way.
- weekly check: 18 × 40 = $720
- periods: 52
- hours: 40
Annual: 720 × 52 = $37,440.00
Per month: $3,120.00
The hourly line prints $18.00, the rate you started with.
Example 8: the common mistake, 26 treated as 24
Here is the common error. Someone is paid $2,400 every two weeks. They multiply by 24 because “twice a month” sounds right.
- pay: $2,400
- periods: 24
Annual: 2400 × 24 = $57,600.00
The real biweekly year is $62,400.00. The gap is $4,800.00.
Monthly on the wrong count is $4,800.00 instead of $5,200.00. Hourly drops from $30.00 to $27.69.

The 24-period mistake

Gross year
26 periods
$62,400
24 periods
$57,600
26 periods, the IRS biweekly count, make $62,400.00.
24 periods make $57,600.00. That is $4,800.00 missing.
The other popular shortcut is weekly pay times 4. $1,200 × 4 = $4,800 for a “month.” A real month is 62400 ÷ 12 = $5,200.00. The ×4 month is short $400.00, twelve times a year.
Example 9: what if the hours change
Hold the $2,400 biweekly check and the 26 periods. Change only the hours.
At 20 hours the year is still $62,400.00. The hour is $60.00, because the same cash is spread over half the time.
At 50 hours the year is still $62,400.00. The hour is $24.00.
The converter does not add overtime premium. The US Department of Labor overtime page is the FLSA rule for time-and-a-half after 40 hours in a workweek, for non-exempt employees. If the $2,400 already includes overtime, the hourly line is an average, not the base rate.

20 hours prints $60.00 an hour on the same $62,400.
50 hours prints $24.00. The year did not change.
Example 10: a $3,500 biweekly check
- pay: $3,500
- periods: 26
- hours: 40
Annual: 3500 × 26 = $91,000.00
Per month: $7,583.33
Per week: $1,750.00
Per hour: $43.75

| 13 | $31k | $46k |
| 20 | $48k | $70k |
| 26 | $62k | $91k |
The $2,400 check is $62,400 after 26 periods.
The $3,500 check is $91,000. Each extra $100 on the check adds $2,600 a year.
Example 11: a 7% raise on the $62,400 year
The raise or pay-cut impact calculator starts from the annual figure, not from the check.
On $62,400 with a 7% raise, 26 periods, and a 28% deduction rate:
New salary: $66,768.00
Gross change per year: $4,368.00
Gross change per biweekly check: $168.00
Estimated net change per month: $262.08
The 28% rate is a planning input, not an IRS table. The raise take-home post walks that limit.
Example 12: 2,080 hours versus 48 working weeks
The salary to hourly pay calculator uses the weeks you actually work. The Office of Personnel Management 2,087-hour divisor is a federal civilian payroll rule, not this converter.
On the same $62,400:
- 40 hours × 52 weeks = 2,080 hours → $30.00 an hour
- 40 hours × 48 weeks = 1,920 hours → $32.50 an hour
The pay-period converter always uses 52 weeks for the hourly line. Use the salary tool when paid time off should change the divisor. The salary to hourly post is that walkthrough.

Open the pay period converter with the check on your stub and the period count from the stub, not from a guess about months. If the question is “what is one working hour worth after PTO,” switch to the salary to hourly tool.
