The problem: the 2,080-hour number that everyone uses and nobody questions
The standard hourly-to-salary conversion is straightforward: multiply the hourly rate by 40 hours per week by 52 weeks per year. That gives 2,080 hours, and $25 per hour becomes $52,000 per year. This number appears on job postings, salary calculators, and labor statistics. It is also almost always wrong for the individual worker, because it assumes 52 weeks of pay with no holidays, no paid time off, and no sick leave. In the United States, the average full-time worker with benefits receives 8 to 10 paid holidays and 10 to 15 days of PTO. That is 3 to 5 weeks of non-working paid time. The hours actually worked per year are closer to 1,920 to 2,000, not 2,080.
The tool lets you set the actual hours per week and weeks worked per year, so you can compute the real number instead of the textbook one. Understanding the difference between gross and take-home, bi-weekly and semi-monthly, and salary and freelance rates is the difference between comparing job offers accurately and comparing them wrong.
Fastest path
Open the Hourly to Salary Calculator, pick a direction (Hourly to Salary or Salary to Hourly), enter the hourly rate or annual salary, set hours per week and weeks worked per year, and the tool shows all seven pay frequencies: hourly, daily, weekly, bi-weekly, semi-monthly, monthly, and annual. The Both Directions tab shows the two calculations side by side for comparison.
The formula and what each variable means
Annual = hourlyRate × hoursPerWeek × weeksPerYear
Hourly = annualSalary ÷ (hoursPerWeek × weeksPerYear)
- hourlyRate is the gross hourly wage before taxes and deductions.
- hoursPerWeek is the number of hours you actually work. Full-time is typically 35-40. The tool defaults to 40.
- weeksPerYear is the number of weeks you are paid for. The tool defaults to 52, but the hint says "use 50 if taking 2 weeks unpaid vacation." If you receive paid vacation, you are still paid for 52 weeks — the weeks are paid even though you do not work them. If your vacation is unpaid, reduce the weeks.
Worked example: $25/hour, 40 hours/week, 52 weeks.
Annual = 25 × 40 × 52 = $52,000
Monthly = 52,000 ÷ 12 = $4,333.33
Weekly = 25 × 40 = $1,000
Same rate, but with 2 weeks unpaid vacation (50 weeks):
Annual = 25 × 40 × 50 = $50,000
Monthly = 50,000 ÷ 12 = $4,166.67
The $2,000 difference comes entirely from the weeks worked input. The tool does not assume 52 — it lets you set the real number.
Bi-weekly vs semi-monthly: 26 vs 24
These two pay frequencies are commonly confused, and the tool shows both so you can see the difference.
Bi-weekly means every two weeks. There are 52 weeks in a year, so bi-weekly pay produces 26 paychecks. Each paycheck is the weekly rate times 2. The annual total is the same, but the per-check amount is smaller because there are more checks. Bi-weekly pay results in two "extra" paychecks per year compared to semi-monthly — in two months of the year, you receive three paychecks instead of two.
Semi-monthly means twice per month, typically on fixed dates like the 1st and 15th or the 15th and 30th. There are 12 months, so semi-monthly pay produces 24 paychecks. Each paycheck is the annual salary divided by 24, which is larger than the bi-weekly check because there are fewer checks.
$52,000 annual:
Bi-weekly: $52,000 ÷ 26 = $2,000 per check (26 checks)
Semi-monthly: $52,000 ÷ 24 = $2,166.67 per check (24 checks)
Monthly: $52,000 ÷ 12 = $4,333.33 per check (12 checks)
The annual total is identical. The difference is the number of checks and the amount per check. Bi-weekly gives you more frequent, smaller payments. Semi-monthly gives you fewer, larger payments on predictable calendar dates. Some months with bi-weekly pay will have three checks, which is useful for budgeting windfalls but confusing for monthly expense planning.
Converting salary to hourly for freelance pricing
If you earn $75,000 per year and want to know what hourly rate to charge as a freelancer, the naive conversion is $75,000 divided by 2,080 = $36.06/hour. This is the rate that matches your current salary if you work 40 hours per week for 52 weeks. But freelancers do not bill for every hour they work — they spend time on admin, client acquisition, bookkeeping, and non-billable tasks. A common rule is that 60 to 70 percent of a freelancer's hours are billable. To match a $75,000 salary with 65 percent billable utilization:
Total hours: 2,080
Billable hours: 2,080 × 0.65 = 1,352
Required hourly rate: 75,000 ÷ 1,352 = $55.48/hour
That is 54 percent higher than the naive $36.06 rate. The tool's Salary to Hourly tab does the base conversion. Adjusting for utilization, self-employment tax (the employer portion of FICA, about 7.65 percent), and benefits you will need to buy yourself (health insurance, retirement contributions) is up to you. The tool shows gross numbers, not effective rates after these costs.
Gotchas
- The tool shows gross pay, not take-home. A $52,000 salary does not put $4,333.33 in your bank account each month. Federal income tax, state income tax (in most states), FICA (Social Security and Medicare at 7.65 percent), health insurance premiums, 401k contributions, and other deductions reduce take-home pay by 25 to 35 percent for most workers. A $52,000 gross salary typically yields $3,000 to $3,300 per month in take-home pay. The tool does not compute tax or deductions.
- Overtime is not included. Under the FLSA, non-exempt employees receive time-and-a-half (1.5 times the regular rate) for hours over 40 per week. If you work 45 hours at $25/hour, your weekly pay is (40 times $25) plus (5 times $37.50) = $1,187.50, not 45 times $25 = $1,125. The tool computes straight-time pay only. For overtime estimation, multiply the excess hours by 1.5 before entering the weekly hours.
- Daily rate assumes a 5-day workweek. The tool computes the daily rate as hourly times (hoursPerWeek divided by 5). If you work 40 hours over 4 days (10-hour shifts), the daily rate shown is $200 (25 times 8), but your actual daily earnings are $250 (25 times 10). The daily figure is an 8-hour equivalent, not your actual daily pay.
- Benefits change the effective rate. A $25/hour job with employer-paid health insurance, 401k match, and 15 days of PTO is worth significantly more than $25/hour with no benefits. The dollar value of benefits can add $5 to $15 per hour to the effective rate. The tool does not account for benefits — it converts cash compensation only.
- Self-employed workers pay both halves of FICA. Employees pay 7.65 percent FICA and the employer pays another 7.65 percent. Self-employed workers pay both halves (15.3 percent total, called self-employment tax). When converting a W-2 salary to a freelance rate, add at least 7.65 percent to account for the employer half you now pay yourself.
Summary
- The formula is annual = hourly times hours per week times weeks per year. The standard 2,080-hour assumption (40 times 52) overstates real hours for most workers because it ignores holidays and PTO. Adjust the weeks worked input to match your actual paid working weeks.
- Bi-weekly is 26 paychecks per year (every two weeks, with two three-check months). Semi-monthly is 24 paychecks per year (twice per month on fixed dates). Same annual total, different check sizes and frequencies.
- Converting salary to hourly for freelance pricing requires adjusting for billable utilization (typically 60-70 percent) and self-employment tax (7.65 percent extra), not just dividing by 2,080.
- The tool shows gross pay. Take-home is 25-35 percent less after taxes, insurance, and retirement contributions. Overtime, benefits, and self-employment tax are not included.
- Use the Hourly to Salary Calculator for the conversion across all seven pay frequencies, the Compound Interest Calculator for long-term savings growth, the Loan Calculator for debt-to-income budgeting, and the Freelance Rate Calculator for rate pricing that accounts for utilization and self-employment costs.
