Weekly Gross Pay Calculator — Every Pay Period, One Answer

Enter your week's regular, overtime and double-time hours and see the gross — then what that week is worth biweekly, monthly and across a year.

In short: combine a week's regular hours at your rate, overtime at 1.5× and double time at 2× into weekly gross pay, then convert it into biweekly, semi-monthly, monthly and annual equivalents (before taxes and withholdings).

Weekly Gross Pay Calculator — And Every Pay Period After It

How It Works — The Rule Behind This Calculator

Gross pay is the full amount earned before anything is withheld: regular hours × rate, plus overtime hours × 1.5 × rate, plus double-time hours × 2 × rate. The period conversions then follow the calendar honestly — a year holds 52 weeks, so biweekly pay is 2 weekly cheques (26 a year), semi-monthly is the annual figure divided by 24, and monthly is the annual figure divided by 12. That is why "monthly" is not simply 4 weekly cheques: 4 weeks is 28 days, shorter than any month but February.

If you need the hours themselves worked out from clock times first, start with the Time Card Calculator and bring its totals here. For take-home (after-tax) questions, remember this page is deliberately gross-only — deductions vary too much by state, filing status and benefits to estimate responsibly here.

Frequently Asked Questions

What is gross pay?

Everything you earn before deductions: regular pay plus overtime and double-time premiums, before income tax, Social Security, Medicare, benefits or garnishments come out. Your pay stub's largest number is the gross.

Why is monthly pay not just 4 times weekly pay?

Because months are longer than 4 weeks. The correct conversion is weekly × 52 ÷ 12. Using ×4 understates monthly gross by about 8%.

How many paycheques do I get in a year?

Weekly: 52. Biweekly: 26 (with two months holding a third cheque). Semi-monthly: 24, always on the same two dates. Monthly: 12.

Does this include taxes?

No — this is a gross-pay calculator by design. Take-home pay depends on federal and state withholding, filing status, pre-tax benefits and more, which a responsible estimate needs far more inputs to model.

Disclaimer: Estimates only — not payroll or legal advice. Your employer's payroll rules and state law control your actual pay. Figures are rounded for display; your pay stub and payroll department are the official record.

How it works — the formula

Enter the week’s hours in three buckets — regular, overtime and double time — and the calculator prices each bucket at its multiplier (1×, 1.5×, 2×) and adds them up. It then scales that single week into the other common pay periods: doubled for biweekly, times 52 for a year, and the year divided by 24 or 12 for semi-monthly and monthly equivalents.

The formula:
Weekly gross = (regular hours × rate) + (overtime hours × rate × 1.5) + (double-time hours × rate × 2)
Biweekly = weekly × 2  ·  Annual = weekly × 52
Semi-monthly = annual ÷ 24  ·  Monthly = annual ÷ 12

Worked example

A week of 40 regular hours, 8 overtime hours and 2 double-time hours at $23.50/hour: regular pay 40 × $23.50 = $940.00; overtime 8 × $35.25 = $282.00; double time 2 × $47.00 = $94.00 — a weekly gross of $1,316.00. Scaled up: biweekly $2,632.00, semi-monthly $2,851.33, monthly $5,702.67, and annual $68,432.00. Those are the exact figures in the calculator’s table for these inputs.

Frequently asked questions

Why is a semi-monthly cheque bigger than a biweekly one?

Because the same annual pay is divided differently: semi-monthly means 24 paydays a year, biweekly means 26. Fewer, larger cheques — in the example, $2,851.33 semi-monthly against $2,632.00 biweekly, from the same $68,432 year.

Do some years have 27 biweekly paydays?

Yes — 26 biweekly periods cover 364 days, so depending on which weekday payday falls, some years fit a 27th payday. This calculator uses the standard 52-week year throughout, so treat its annual figure as the normal-year equivalent rather than a promise about a specific calendar year.

My hours change every week. Are the annual figures still right?

Only as an illustration. Every equivalent on this page assumes the week you typed repeats unchanged for 52 weeks. If your hours vary, run the page for a typical week to get a fair picture, and expect the real year to land above or below it.

Where do double-time hours come from?

Double time (2×) is owed under some state daily rules — California, for example, pays 2× after 12 hours in a day — and under some employer policies and union contracts for Sundays or holidays. Enter in this bucket only the hours that will actually be paid at 2×; what qualifies is set by the law that applies to you and your employer’s policy.

Can I use this to compare two job offers?

Yes — enter each offer’s typical week (its usual regular and overtime hours at its rate) and compare the weekly and annual equivalents side by side. Just remember both figures are gross: taxes, benefits and commuting costs can change which offer is really better.
