Hourly to Salary Calculator: What $30 an Hour Really Pays in a Year
An hourly to salary calculator turns a pay rate into the yearly figure that actually matters when you compare jobs, sign a lease, or set a budget. It takes the amount you're paid, how often you're paid it, and your weekly schedule, then converts it into every standard pay period: hourly, daily, weekly, bi-weekly, semi-monthly, monthly, quarterly, and annual. The result is one consistent set of numbers, so a $30 an hour offer and a $62,400 salary stop looking like two different jobs and start looking like the same job described two ways.
That conversion sounds simple, and the arithmetic is. What trips people up is everything around it: paid days off, part-time hours, and the difference between what you are paid per hour worked and what you effectively earn per hour of the year. This calculator handles the first two directly, and its adjusted figures handle the third, which is where most mental math goes wrong.
How the conversion works
Every conversion starts from the annual figure. The calculator multiplies your pay amount by the number of pay periods in a year: an hourly rate times hours per week times 52, a daily rate times days per week times 52, a weekly rate times 52, a bi-weekly rate times 26, a semi-monthly rate times 24, a monthly rate times 12, a quarterly rate times 4, and a yearly rate times 1. Once the annual figure exists, every other period is a division of it. The hourly rate is the annual figure divided by hours per week times 52, and the monthly figure is the annual figure divided by 12.
The adjusted figures answer a different question: what is each hour of the year worth once paid days off are counted? Holidays and vacation days are days you're paid for but don't work, so the calculator subtracts them from the year's working hours and divides the same annual pay by the smaller number of hours actually worked. The annual total doesn't change. Only the per-hour, per-day, and per-week rates move, and they move up, because the same pay now covers fewer working hours.
Every input, explained
Pay amount. The number you are paid in one pay period, before tax. Enter it exactly as your offer or payslip states it, without currency symbols or commas. Paid per. The period that pay amount covers: hour, day, week, bi-weekly, semi-monthly, month, quarter, or year. Check it against your contract, not your memory.
Hours per week. The hours you work in a normal week, from 1 to 168. This drives the hourly conversion, so a part-time schedule changes the annual figure a lot. Days per week. The days you work in a normal week, from 1 to 7. It sets the length of your working day, which is hours per week divided by days per week, and that day length is what turns days off into hours off.
Holidays per year. Paid public holidays you do not work, from 0 to 365. Vacation days per year. Paid vacation days you take, from 0 to 365. Together they feed only the adjusted figures. If you leave both at zero, the adjusted column matches the standard column exactly, which is a useful sanity check that you entered everything right.
A worked example: $30 an hour, 40 hours a week, 20 paid days off
A worker is offered $30 an hour, working 40 hours a week across 5 days, with 10 public holidays and 10 vacation days a year. The year holds 2,080 working hours, and the annual pay is $30 times 2,080, which is $62,400. Every other period follows from that one number, and the table shows the full conversion.
| Pay period | Standard | Adjusted for days off |
|---|---|---|
| Hourly | $30.00 | $32.50 |
| Daily | $240.00 | $260.00 |
| Weekly | $1,200.00 | $1,300.00 |
| Bi-weekly | $2,400.00 | $2,600.00 |
| Semi-monthly | $2,600.00 | $2,600.00 |
| Monthly | $5,200.00 | $5,200.00 |
| Quarterly | $15,600.00 | $15,600.00 |
| Annual | $62,400.00 | $62,400.00 |
The adjusted column comes from the days off. Twenty days off at 8 hours a day remove 160 hours from the year, leaving 1,920 hours actually worked. Dividing the same $62,400 by 1,920 gives $32.50 an hour. That's the rate each working hour is effectively worth once paid time off is counted, and it's the number to use when you compare this job with one that offers fewer paid days off but a higher hourly rate.
Two more conversions show how much the schedule matters. A part-time worker at $25 an hour for 25 hours a week earns $32,500 a year, or $2,708.33 a month, barely half the full-time figure despite a rate only $5 lower. A salaried worker on $75,000 a year earns $36.06 an hour on a 40 hour week, $1,442.31 a week, and $6,250 a month. A $5 raise, from $30 to $35 an hour at full time, adds $10,400 a year, which is why hourly differences that look small in a job offer are large in a yearly budget.
Common mistakes
- Multiplying the hourly rate by 2,000 instead of 2,080. A 40 hour week times 52 weeks is 2,080 hours, not 2,000. The shortcut understates annual pay by $2,400 on a $30 rate.
- Mixing up bi-weekly and semi-monthly. Bi-weekly pay arrives 26 times a year, semi-monthly 24 times. A $2,400 bi-weekly paycheck is $62,400 a year, while a $2,400 semi-monthly paycheck is $57,600. Same check size, different salary.
- Comparing gross figures with take-home figures. This calculator converts gross pay before tax. If one offer quotes take-home pay and the other quotes gross pay, the comparison is meaningless until both are put on the same basis.
- Forgetting unpaid time off. The adjusted figures cover paid days off only. Unpaid leave reduces the annual total itself, so a job with generous unpaid leave needs a separate adjustment, not this one.
- Ignoring the schedule behind a salary. Two $62,400 salaries are not equal if one expects 40 hours a week and the other expects 50. Convert both to hourly rates before deciding which pays better.
Practical tips
Use the monthly figure for budgeting and the hourly figure for comparing offers, since rent and bills arrive monthly while job offers are usually quoted hourly or yearly. When an offer includes paid days off, compare adjusted hourly rates, not headline rates: a $30 rate with 20 paid days off beats a $31 rate with none, because $32.50 of effective hourly value beats $31.00. Re-run the conversion whenever your schedule changes, because a move from 40 hours to 32 hours cuts annual pay by a fifth even though the hourly rate never moves.
Frequently asked questions
$30 an hour is how much a year?
At 40 hours a week for 52 weeks, $30 an hour is $62,400 a year, $5,200 a month, and $1,200 a week. With 20 paid days off, the adjusted rate is $32.50 per hour actually worked, though the annual total stays $62,400.
What is the difference between bi-weekly and semi-monthly pay?
Bi-weekly pay arrives every two weeks, 26 times a year, so two months a year bring three paychecks. Semi-monthly pay arrives twice a month on fixed dates, 24 times a year, with no three-paycheck months. The same check size gives a different annual salary under each one.
Why is my adjusted hourly rate higher than my actual hourly rate?
Because paid days off mean you are paid for hours you do not work. The calculator divides your full annual pay by the hours you actually work, which are fewer, so each working hour carries more value. Your annual pay does not change; only the per-hour view of it does.
Does this calculator include taxes or overtime?
No. It converts gross pay across periods only, with no tax, overtime premium, or deduction applied. Use a tax calculator for take-home pay, and treat overtime as a separate addition, since overtime hours are usually paid at a higher rate than the base rate.
How do I convert a salary back to an hourly rate?
Divide the annual salary by your yearly working hours, which are hours per week times 52. A $75,000 salary on a 40 hour week is $75,000 divided by 2,080, or $36.06 an hour. Enter the salary with "year" as the pay period and the calculator does the rest.

A pay rate only means something once it is stretched across a full year and set against the hours it actually buys, and that is where most offer comparisons go wrong: two jobs can quote nearly the same hourly number and still pay thousands apart once schedules and paid days off are counted. Run your own rate through every period, check the adjusted column before you accept, and carry the monthly figure into your budget.
