Number Overtime Calculator
Overtime is where paychecks get interesting — and where they get miscalculated. Enter your rate, your regular hours, and the hours you worked at time-and-a-half and double time, and see the week, the month and the year in gross pay.
Under US federal rules, non-exempt workers earn at least 1.5× after 40 hours in a week; some states add daily overtime, and some employers pay 2× for Sundays and holidays. Monthly = weekly × 52 ÷ 12; annual = weekly × 52.
How it works
Three buckets, three rates: regular hours × your rate, 1.5× hours × rate × 1.5, and 2× hours × rate × 2. Add them for the week; the year is the week × 52 and the month is the year ÷ 12. The blended rate — total pay ÷ total hours — is the single number that tells you what your time actually earned, and it is the fairest way to compare a heavy-overtime week against a straight-time one.
Formula & worked example
Formula: Weekly gross = (regular hours × rate) + (overtime hours × rate × 1.5) + (double-time hours × rate × 2). Monthly = weekly × 52 ÷ 12; annual = weekly × 52. Blended rate = weekly gross ÷ total hours worked.
Worked example: At $20 an hour with 40 regular hours and 10 hours at time-and-a-half: $800 + $300 = $1,100 for the week, $4,766.67 a month, $57,200 a year — a blended rate of $22.00 an hour across the 50 hours.
When to use this
- A heavy week just landed and you want the gross figured before the payslip arrives, to check it against.
- You are deciding whether offered overtime is worth the Saturday, in actual dollars at your rate.
- You hold two jobs at different rates and want to see which one's extra hours pay better after the premium.
- You are budgeting on overtime income and need the honest monthly average rather than a good week times four.
How to use it, step by step
- Enter your base hourly rate.
- Enter the regular hours for the week — usually 40.
- Enter the hours paid at time-and-a-half in their own field, and any double-time hours in theirs.
- Read the weekly gross first, then the monthly and annual projections.
- Check the blended rate: it is what the whole week really paid per hour, premiums included.
What the inputs mean
| Input | What it is | Typical values |
|---|---|---|
| Hourly rate | Base rate the premiums multiply | $20 is the page default |
| Regular hours | Hours paid at the base rate this week | 40 in a standard full-time week |
| Hours at 1.5 times | Time-and-a-half hours, paid at rate times 1.5 | Hours past 40 in the week under federal rules |
| Hours at 2 times | Double-time hours, paid at twice the rate | Sundays, holidays or contract hours, depending on policy |
Another worked example
At $25 an hour with 40 regular hours, 6 hours at time-and-a-half and 4 hours at double time: regular pay is $1,000, the 1.5 times hours pay $225, and the double-time hours pay $200, for a weekly gross of $1,425. Held every week that is $6,175.00 a month and $74,100 a year, and the blended rate across all 50 hours is $28.50 an hour — the double-time block is doing more for that figure than its four hours suggest.
Frequently asked questions
How much is 10 hours of overtime at $20 an hour?
Time-and-a-half makes the overtime rate $30, so 10 OT hours pay $300. With 40 regular hours ($800) the week totals $1,100 gross — $4,766.67 a month and $57,200 a year if every week looked like that. Your blended rate across the 50 hours is $22 an hour.
What is the difference between 1.5× and 2×?
1.5× ("time-and-a-half") pays your rate plus half — $20 becomes $30. 2× ("double time") pays twice the rate — $20 becomes $40. Federal law requires 1.5× past 40 weekly hours for non-exempt staff; 2× is usually employer policy, union contract, or specific state/holiday rules.
Is overtime taxed more?
No — that is a myth with a kernel of truth. Overtime income is taxed at the same rates as regular income. A big OT paycheck can be withheld as if you earned that pace all year, which over-withholds in the moment, but it settles up at tax time.
Why is monthly not just weekly × 4?
Because months are not four weeks: a year has 52 weeks and 12 months, so the average month holds 4.33 weeks. Monthly = weekly × 52 ÷ 12 is the honest conversion — weekly × 4 quietly underpays your estimate by about 8%.
💵 Gross is only half the story
The Paycheck Calculator takes gross pay through taxes and deductions to the take-home figure.
Who decides which of my hours land in the 1.5 or 2 times bucket?
Not this calculator — you enter the split, and the split comes from the rules that govern your job. Federal law sets the floor at time-and-a-half past 40 hours a week for non-exempt workers; double time usually comes from an employer's policy, a union contract, or a state or holiday rule. If your payslip splits the hours differently than you expected, that rule source is where the answer lives.
Are salaried employees owed overtime at all?
It depends on exemption status, not on the word salary itself. Non-exempt salaried workers are generally still owed the premium past the threshold; exempt roles — many executive, professional and administrative jobs meeting both a duties test and a salary threshold — are not. This calculator models hourly buckets, so a salaried non-exempt check usually starts by deriving the hourly rate from the salary and the hours it covers.
