Weekly Pay Calculator
Turn an hourly wage into a week of gross pay. Enter your rate in dollars per hour and your hours for the week — anything over 40 is paid at time and a half, the federal overtime standard.
Example: with Hourly rate ($) 20 · Hours this week 42 → Gross weekly pay: $860 per week, pre-tax.
- At this pace$44,720 per year · $3,727 per month
- Overtime portion$60 of that is overtime (2 h at $30.00/h)

Gross pay = rate × hours, with hours over 40 paid at 1.5× (FLSA overtime for nonexempt workers). Taxes are not deducted here.
From an hourly rate to a week of pay
Weekly gross pay is rate × hours for the first 40 hours, then rate × 1.5 for every hour beyond — the Fair Labor Standards Act overtime floor for nonexempt employees. At $20 an hour, a 42-hour week pays $800 regular plus $60 overtime: $860 before taxes.
Overtime is measured per workweek, not per day or per pay period, under the federal rule. A 45-hour week followed by a 35-hour week earns 5 overtime hours even though the two weeks average 40 — employers can't net them out.
Scaling a week up honestly
To annualize, multiply the weekly figure by 52; for a monthly figure, divide the annual number by 12. The tempting shortcut of multiplying a week by 4 understates the month, because an average month contains about 4.33 weeks. And remember everything here is gross — take-home pay drops once federal and state taxes, Social Security, Medicare, and benefits come out.
How it’s calculated
Gross weekly pay = hourly rate × hours up to 40, plus 1.5 × rate × hours over 40 (the FLSA overtime standard for nonexempt employees). Annual = weekly × 52; monthly = annual ÷ 12. All figures are pre-tax gross estimates.
Assumes one pay rate and the federal weekly overtime rule; state variants (California's daily overtime, for example), double-time policies, and exempt salaried roles aren't modeled.
Gross weekly pay at common hourly rates
| Hourly rate | 40 hours | 45 hours (5 h OT) |
|---|---|---|
| $15 | $600 | $712.50 |
| $18 | $720 | $855.00 |
| $20 | $800 | $950.00 |
| $25 | $1,000 | $1,187.50 |
| $30 | $1,200 | $1,425.00 |
Computed as rate × 40 + 1.5 × rate × overtime hours.
Common mistakes
- Multiplying weekly pay by 4 for a monthly figure — months average 4.33 weeks, so use annual ÷ 12 instead.
- Applying overtime after 8 hours in a day; the federal rule is over 40 in a workweek (only some states, like California, add daily overtime).
- Comparing this gross number to a take-home paycheck — taxes and deductions haven't been removed.
- Entering a two-week total (80 hours) as one week, which wrongly triggers 40 hours of overtime.
Frequently asked questions
How is weekly pay calculated?
Gross weekly pay = hourly rate × hours up to 40, plus 1.5 × rate for each hour over 40. At $20/hour and 42 hours: 40 × $20 + 2 × $30 = $860.
How much is $20 an hour per week?
$800 gross for a standard 40-hour week. Over a year that pace is $41,600; each overtime hour at $20 adds $30 more.
What's the difference between weekly and biweekly pay?
Biweekly pay covers two workweeks, so it's roughly double a weekly check — but overtime is still computed week by week within the period, and there are 26 biweekly periods a year versus 52 weekly ones.
Is this my take-home pay?
No — it's gross. Federal and state income tax, Social Security, Medicare, and any benefits or retirement contributions come out before the check hits your account, commonly taking a quarter or more.
Does a salaried job convert the same way?
For comparison, divide annual salary by 52 to get a weekly equivalent. The overtime math here applies to nonexempt hourly workers; most salaried-exempt roles don't earn 1.5× past 40 hours.
