Hourly Pay Calculator

Your paycheck should be simple: hours worked times hourly rate, plus a little extra for overtime. In practice, paychecks confuse millions of workers every week. Overtime rules, the split between regular and overtime hours, and the gap between gross and take-home pay turn a supposedly simple calculation into guesswork. Many employees never verify their pay stubs at all, trusting that payroll got it right, even though payroll errors are surprisingly common and almost always favor the employer, never the worker waiting on that check.

The free Hourly Pay Calculator on this page puts the math back in your hands. Enter your total hours worked, your hourly pay rate, and your overtime hours, and it instantly breaks your earnings into regular pay, overtime pay at time-and-a-half, and total pay. This guide explains how hourly pay and overtime work, walks through the calculations step by step, and shows you how to use the results to check every paycheck with confidence.

How Hourly Pay Works

Hourly pay compensates you for each hour you work at an agreed rate. If your rate is $22.50 and you work 40 hours, your regular earnings are $900. The system is transparent by design: more hours means proportionally more pay, and the rate is stated upfront so both sides know the deal.

Overtime is where the rules get interesting. In the United States, federal law requires most hourly workers to receive at least 1.5 times their regular rate for hours worked beyond 40 in a single workweek. So those same $22.50 hours become $33.75 once you cross the 40-hour line. Some states and some employers are more generous, with double time after 12 hours in a day or on the seventh consecutive workday, but time-and-a-half past 40 is the national baseline.

Crucially, overtime is calculated on overtime hours specifically, not on all hours. A common misunderstanding is that working 45 hours means all 45 are paid at the higher rate. In reality, 40 hours are paid at the regular rate and only the 5 extra hours get the 1.5 multiplier. The calculator enforces this split automatically, which is exactly why its regular-pay figure uses total hours minus overtime hours.

Regular Pay vs Overtime Pay

Regular pay covers your non-overtime hours at your base rate. If you worked 45 hours total with 5 overtime hours, your regular hours are 40 and your regular pay is 40 times your rate. Overtime pay covers just the overtime hours at 1.5 times the rate, so 5 hours at time-and-a-half. Total pay is the sum of the two.

This split matters beyond curiosity. Overtime pay is often taxed the same as regular pay, despite the persistent myth of a special overtime tax, but it can push you into situations like higher withholding on a particular check. Understanding the split also lets you evaluate trade-offs: five overtime hours at $22.50 base pay earn you $168.75 extra, which prices your weekend time precisely.

Some employers average hours across two weeks to dodge overtime, but federal law generally forbids that: each workweek stands alone. If you worked 45 hours this week and 35 last week, you are owed 5 hours of overtime even though the two-week average is 40. Knowing the rule helps you spot violations.

The Math Behind the Hourly Pay Calculator

The calculator uses three straightforward formulas. Regular pay equals total hours minus overtime hours, multiplied by the hourly rate. Overtime pay equals overtime hours multiplied by the rate multiplied by 1.5. Total pay equals regular pay plus overtime pay.

With 45 total hours, a $22.50 rate, and 5 overtime hours, the math runs: regular pay is 40 times $22.50, or $900.00; overtime pay is 5 times $22.50 times 1.5, or $168.75; total pay is $900.00 plus $168.75, or $1,068.75. Every figure is rounded to two decimal places to match real payroll presentation.

The calculator validates your inputs before computing. Total hours cannot be negative, the rate cannot be negative, overtime hours cannot be negative, and overtime hours cannot exceed total hours. These guards catch the typos, like entering 50 overtime hours against 45 total hours, that would otherwise produce nonsense results.

How to Use the Hourly Pay Calculator

Checking a paycheck takes less than a minute:

1. Enter your total hours worked for the pay period’s week, for example 45.
2. Enter your hourly pay rate in dollars, for example 22.50.
3. Enter your overtime hours, meaning hours beyond 40 in the week, for example 5.
4. Click Calculate to see your regular pay, overtime pay, and total pay.

Compare the total pay figure against the gross pay line on your pay stub. If they match, payroll is correct. If they differ, you have a precise, documented discrepancy to raise with your employer.

Worked Example 1: A 45-Hour Week at $22.50

You worked 45 hours this week at $22.50 per hour, with 5 of those hours qualifying as overtime. Here is the calculator’s step-by-step work.

First, it separates the hours: 45 total minus 5 overtime leaves 40 regular hours. Regular pay is 40 times $22.50, which equals $900.00. Next, overtime pay: 5 hours times $22.50 times 1.5. The overtime rate is $33.75 per hour, and 5 times $33.75 equals $168.75. Finally, total pay is $900.00 plus $168.75, which equals $1,068.75.

Those 5 overtime hours earned you $168.75 instead of the $112.50 they would have paid at the straight rate, a $56.25 premium for the extra time. Annualized, working 5 overtime hours every week at this rate adds $8,775 a year to your income, which reframes “just a few extra hours” as serious money.

If your pay stub shows gross pay of $1,068.75 for this week, everything checks out. If it shows $1,012.50, payroll likely paid your overtime at the straight rate, and you are owed the $56.25 difference. That is the kind of catch the calculator makes routine.

Worked Example 2: A 38-Hour Week With No Overtime

Now take a lighter week: 38 hours at $18.75 per hour with zero overtime hours. The calculator handles no-overtime weeks just as cleanly.

Regular hours are 38 minus 0, or 38. Regular pay is 38 times $18.75, which equals $712.50. Overtime pay is 0 times $18.75 times 1.5, which is $0.00. Total pay is $712.50 plus $0.00, or $712.50.

This example confirms an important detail: the calculator never invents overtime. Entering 0 overtime hours yields exactly the straight-time result, so the tool works for part-time schedules, short weeks, and salaried-style checks just as well as for overtime-heavy weeks.

It also shows the value of tracking partial weeks. Two hours short of 40 at $18.75 costs you $37.50 in gross pay, plus any overtime premium you might have earned. When hours fluctuate, running each week through the calculator builds an accurate picture of what your month really earned.

Why Paychecks Often Differ From Your Estimate

When the calculator’s total does not match your pay stub, do not panic; several legitimate reasons explain small gaps. The most common is the pay period: the calculator works per workweek, but your stub may cover two weeks, a half month, or a month. Multiply or divide accordingly before comparing.

Withholding is the next suspect. The calculator shows gross pay, while your bank receives net pay after federal and state taxes, Social Security, Medicare, and deductions for insurance or retirement. A stub showing less than the calculator’s total is normal; the gross-pay line on the stub is the figure to compare against.

One more subtle cause is the overtime threshold itself. If your employer’s defined workweek runs Wednesday to Tuesday but you think in Monday-to-Sunday weeks, hours you consider one week’s overtime may fall into two different official workweeks. Always confirm the official workweek definition before declaring a discrepancy. Rounding and rate quirks cause tiny differences too. Some payroll systems round hours to the nearest quarter, and shift differentials or holiday premiums change the effective rate for specific hours. If the gap is a few dollars, ask payroll how those hours were classified. If the gap is large and unexplained, escalate in writing.

Know Your Overtime Rights

Not every worker is entitled to overtime. Federal law exempts certain salaried, managerial, and professional roles, and the salary threshold for exemption changes over time. If you are classified as exempt, your employer is not required to pay overtime no matter how many hours you work, which makes your classification worth understanding.

Misclassification is a real and common problem. Some employers label workers as exempt or as independent contractors to avoid overtime obligations they legally owe. If you are paid hourly, supervised closely, and working over 40 hours without premium pay, your classification deserves scrutiny regardless of your job title.

Keep your own hours log. Phones, apps, or a simple notebook all work. When your records disagree with the employer’s, contemporaneous personal logs carry real weight in disputes. The calculator plus your own log turns every paycheck into a verifiable fact rather than a leap of faith.

Shift Differentials, Holiday Premiums, and Blended Rates

Real paychecks are rarely as clean as the base example. Night shifts often carry a differential, an extra dollar or two per hour, and weekend or holiday shifts can carry premiums of their own. When your hours mix different rates, overtime gets calculated on a blended regular rate: total straight-time earnings divided by total hours worked, times 1.5 for the overtime hours. The calculator’s single-rate math is your starting point; for mixed-rate weeks, compute each rate block separately and add them.

Holiday pay deserves special care. Many employers pay extra for working a holiday, sometimes double time, but those holiday hours only count toward the 40-hour overtime threshold if you actually worked them. Paid time off for a holiday you did not work generally does not create overtime by itself. If your week mixes holiday premium hours and regular hours, run each group through the calculator separately with its own effective rate, then add the totals.

Bonuses and commissions can also feed the overtime calculation. Non-discretionary bonuses, those you earn by hitting targets rather than gifts from the boss, must be folded into the regular rate before computing overtime. This is one of the most underpaid areas in payroll: workers receive the bonus but never see the overtime recalculation it triggers. If you earn regular production bonuses and work overtime in the same period, ask payroll whether the bonus was included in your overtime rate.

Tips for Getting Every Dollar You Earned

1. 1. Verify every paycheck against the calculator. — Run your hours, rate, and overtime through the tool and compare its total to the gross-pay line on your stub.
2. 2. Track overtime hours separately. — Log overtime distinctly from regular hours so the 1.5 multiplier is applied to the right hours.
3. 3. Learn your state’s overtime rules. — Some states mandate daily overtime or double time that exceeds the federal baseline, and you should claim every premium you are owed.
4. 4. Confirm your exemption status. — Make sure you are classified correctly, because misclassified workers lose thousands in unpaid overtime.
5. 5. Keep your own time records. — Personal logs protect you when the employer’s records are wrong or conveniently incomplete.
6. 6. Price overtime before volunteering. — Multiply the premium by your hours to see exactly what extra shifts are worth before saying yes.
7. 7. Watch the workweek boundary. — Overtime resets each workweek, so hours cannot legally be averaged across weeks to erase the premium.
8. 8. Raise discrepancies in writing. — A dated written query about a pay shortfall creates a record and usually gets faster correction than a hallway mention.

1. How is overtime pay calculated?

Multiply your overtime hours by your regular rate times 1.5. Five overtime hours at $20 an hour pay 5 times $30, or $150.

2. After how many hours do I get overtime?

Under federal law, hours beyond 40 in a single workweek qualify for time-and-a-half. Some states require it sooner, such as after 8 hours in a day.

3. Is overtime taxed at a higher rate?

No. Overtime is taxed as ordinary income at your normal rates. The myth comes from higher withholding on bigger checks, which evens out at tax time.

4. What if I work 45 hours but my stub shows no overtime?

First check whether you are classified as exempt. If you are non-exempt, calculate the shortfall with the calculator and raise it with payroll in writing.

5. Can my employer average my hours over two weeks?

Generally no. Federal law treats each workweek independently, so 45 hours one week and 35 the next still earns 5 overtime hours.

6. What is double time?

Double time pays twice your regular rate and applies in some states after 12 hours in a day or on the seventh consecutive workday, depending on local law.

7. Do salaried workers get overtime?

Only if they are non-exempt. Many salaried workers are exempt, but salary alone does not determine exemption; duties and pay level matter too.

8. How do I check my pay stub with the calculator?

Enter the week’s total hours, your rate, and overtime hours, then compare the calculator’s total pay to the gross-pay line on your stub.

9. What counts as the workweek?

Any fixed, recurring 168-hour period your employer defines. Overtime is measured within each workweek, not across calendar weeks or pay periods.

10. Are breaks paid at the overtime rate?

Short paid rest breaks count as hours worked, but unpaid meal periods do not. Only actual hours worked feed the overtime calculation.

11. Can I refuse overtime work?

Usually your employer can require it, but they must pay the legal premium for it. Check your state law and any union contract for specific limits.

12. Does holiday pay count toward overtime?

Only hours actually worked count toward the 40-hour threshold. Paid holiday hours where you did not work generally do not trigger overtime by themselves.

13. What should I do about a pay shortfall?

Document it with your own hours log and the calculator’s figures, then raise it with payroll in writing and keep copies of everything.

14. Are independent contractors owed overtime?

No. Overtime law covers employees, not genuine independent contractors, which is why misclassification disputes matter so much.

15. How much is 5 overtime hours worth at $22.50?

At time-and-a-half, 5 hours times $33.75 equals $168.75, which is $56.25 more than those hours would pay at the straight rate.

CONCLUSION

Your pay is too important to take on faith. The Hourly Pay Calculator splits any week’s work into regular pay, overtime pay, and total pay in seconds, giving you a precise benchmark for every pay stub. Learn your overtime rights, log your own hours, verify each check against the gross-pay line, raise discrepancies in writing, and never let a busy payroll department be the only one doing your math. A one-minute check per paycheck is the cheapest insurance your earnings will ever have, and the workers who check are the workers who get paid correctly.
