Base Calculations

Annual Working Days (Unadjusted):
Annual Days = Days per week × 52 weeks
Annual Working Hours (Unadjusted):
Annual Hours = Hours per week × 52 weeks
Hours per Day:
Hours per Day = Hours per week ÷ Days per week

From Hourly Rate

Daily = Hourly Rate × Hours per Day
Weekly = Hourly Rate × Hours per Week
Biweekly = Hourly Rate × Hours per Week × 2
Semi-monthly = (Hourly Rate × Hours per Week × 52) ÷ 24
Monthly = (Hourly Rate × Hours per Week × 52) ÷ 12
Quarterly = (Hourly Rate × Hours per Week × 52) ÷ 4
Annual = Hourly Rate × Hours per Week × 52

Vacation & Holiday Adjustments

Total Time Off Days = Holidays per Year + Vacation Days per Year
Hours Lost to Time Off = Total Time Off Days × Hours per Day

Adjusted Annual Hours = (Hours per Week × 52) − Hours Lost to Time Off

Adjusted Hourly = Annual Salary ÷ Adjusted Annual Hours

Adjusted Daily = Adjusted Hourly × Hours per Day
Adjusted Weekly = Adjusted Hourly × Hours per Week
Adjusted Biweekly = Adjusted Hourly × Hours per Week × 2

Working Days Calculation

Unadjusted Annual Working Days = 52 × Days per Week
Adjusted Annual Working Days = (52 × Days per Week) − (Holidays + Vacation)

Payment Frequency Conversions

To Annual from Any Frequency:
• Hourly: Annual = Hourly × Hours per Week × 52
• Daily: Annual = Daily × Days per Week × 52
• Weekly: Annual = Weekly × 52
• Biweekly: Annual = Biweekly × 26
• Semi-monthly: Annual = Semi-monthly × 24
• Monthly: Annual = Monthly × 12
• Quarterly: Annual = Quarterly × 4

Between Pay Periods

Biweekly to Semi-monthly:
Semi-monthly = (Biweekly × 26) ÷ 24

Weekly to Biweekly:
Biweekly = Weekly × 2

Monthly to Biweekly:
Biweekly = (Monthly × 12) ÷ 26

Payment Periods Explained

Hourly Pay

The most basic unit of compensation, paid per hour worked. Typically used for part-time and hourly workers. Unadjusted value does not account for holidays/vacation.

Daily Pay

Payment calculated per working day. Usually equals hourly rate multiplied by hours per day (typically 8 hours). Useful for contract and gig workers.

Weekly Pay

Payment for one week of work. With standard 40-hour weeks, this equals hourly rate × 40. Some employers use weekly pay periods for easier payroll management.

Biweekly Pay (26 times/year)

The most common pay frequency in the US. Employees receive 26 paychecks per year, every 2 weeks. Each check covers 80 hours of work at standard 40-hour weeks.

Semi-monthly Pay (24 times/year)

Two paychecks per month, typically on the 15th and last day. Results in 24 paychecks annually. Semi-monthly checks are typically larger than biweekly due to fewer total checks.

Monthly Pay (12 times/year)

One paycheck per month, common in professional and salaried positions. Requires careful budgeting as each payment is larger but less frequent.

Quarterly Pay (4 times/year)

Four paychecks per year, used by some contractors or seasonal workers. Requires significant financial planning and expense management.

Annual Salary

The total compensation for one year of work. This is the standard way salaries are quoted for full-time positions (e.g., "$50,000 annual salary").

Unadjusted vs. Adjusted

Unadjusted values ignore holidays and vacation days, assuming 260 working days per year. Adjusted values account for time off, resulting in lower per-period payments but representing true working time compensation.

Calculation Methodology

Standard Assumptions

📌 Default Values Used:
• 52 working weeks per year
• 260 working days per year (52 weeks × 5 days)
• 2,080 working hours per year (52 weeks × 40 hours)
• 10 federal holidays per year
• 15 vacation/PTO days per year

Step-by-Step Calculation Process

Step 1: Identify the input salary amount and its frequency (e.g., $50/hour).

Step 2: Convert the input to an annual salary using the base formula (Hourly × 40 × 52 = Annual).

Step 3: Calculate unadjusted values for all payment frequencies from the annual amount.

Step 4: Calculate hours/days lost to holidays and vacation (e.g., 10 days + 15 days = 25 days × 8 hours = 200 hours).

Step 5: Adjust annual working hours (2,080 − 200 = 1,880 adjusted hours).

Step 6: Calculate adjusted hourly rate using adjusted hours (Annual ÷ 1,880 = adjusted hourly).

Step 7: Calculate adjusted values for all payment frequencies using the adjusted hourly rate.

Important Notes

💡 Hourly & Daily are Unadjusted: These are treated as base rates not affected by time off. Adjusted values show the effective rate per working period.
💡 Biweekly vs. Semi-monthly: Biweekly (26/year) is different from semi-monthly (24/year). The same annual salary results in different per-check amounts.
⚠️ Part-time Schedules: For part-time positions, adjust the "Hours per Week" field accordingly. A 20-hour/week employee earns half of a 40-hour/week employee at the same hourly rate.

Examples

Example 1 - $50/hour:

  • Annual: $50 × 40 × 52 = $104,000 (unadjusted)
  • Monthly: $104,000 ÷ 12 = $8,667 (unadjusted)
  • With 25 days off: 2,080 − 200 = 1,880 hours
  • Adjusted hourly: $104,000 ÷ 1,880 = $55.32
  • Adjusted annual: ~$94,000 (accounting for time off)

Example 2 - $100,000 annual salary:

  • Biweekly (26 checks): $100,000 ÷ 26 = $3,846.15
  • Semi-monthly (24 checks): $100,000 ÷ 24 = $4,166.67
  • Monthly (12 checks): $100,000 ÷ 12 = $8,333.33
  • Hourly (40 hrs/week): $100,000 ÷ 2,080 = $48.08

Frequently Asked Questions

What's the difference between biweekly and semi-monthly pay? +
Biweekly pay occurs every 2 weeks (26 paychecks/year). Semi-monthly pay occurs twice per month (24 paychecks/year). With the same annual salary, biweekly checks are smaller ($3,846 vs. $4,167 for $100k salary). Biweekly is more common in the US.
How many working hours per year? +
Standard full-time employee: 2,080 hours/year (40 hours/week × 52 weeks). This calculator defaults to 260 working days and allows adjustments for holidays and vacation. With 25 days off, adjusted hours would be 1,880 (2,080 − 200).
Why are hourly and daily rates unadjusted? +
Hourly and daily rates are base rates paid per unit of time worked. Holidays and vacation are paid time off (you're paid but don't work), so they don't affect the hourly rate. The adjustment affects total annual earnings, not the base rate.
How do I calculate net pay after taxes? This calculator shows gross pay only. Net pay depends on tax withholding (federal, state, local), FICA taxes, and deductions. Typically, employees take home 75-85% of gross pay. Use a paycheck calculator to estimate net pay.
Can I customize work schedules? +
Yes! Adjust "Hours per Week" and "Days per Week" for any schedule. Part-time (20 hrs/week), compressed schedules (10 hrs/day, 4 days), or shift work can all be entered. The calculator adapts automatically.
What about overtime and bonuses? This calculator shows base salary only. Overtime (typically 1.5× or 2× hourly rate) and bonuses aren't included. Add them separately to your annual salary, or use the "Salary Amount" as a base and calculate overtime effects separately.
Is this calculator accurate for international salaries? +
Yes, the formulas work universally. However, working days per year vary by country (Canada: 260, UK: 260, Australia: 260, etc.). Adjust the "Days per Week" and "Holidays per Year" for your location. The calculations are currency-neutral.
Why does adjusted salary differ from unadjusted? Unadjusted assumes you work every single day of the year (no days off). Adjusted accounts for realistic time off (holidays, vacation). The difference shows how much of your annual salary goes to paid time off. Adjusted values are typically 5-12% lower than unadjusted.
Can I use this for freelance/contract work? +
Yes! Freelancers can use this to convert between hourly rates and annual revenue targets. For example, if you bill $100/hour and want to earn $50,000/year, the calculator shows you need ~500 billable hours (roughly 10 hours/week for 50 weeks).
