How to calculate annual income from hourly, weekly or monthly pay

Almost every money question I get asked starts with a pay figure quoted the wrong way round: a job advert states an hourly rate, a lender wants an annual salary, and a budget needs a monthly number. Converting between them is not hard — it is three multiplications — but each one hides an assumption about hours and weeks that changes the answer if you get it wrong. Here is how to calculate annual income from any pay schedule, how to calculate monthly income on the way back, and the two adjustments that separate the headline figure from the real one.

Start with the two assumptions behind every conversion

Every pay conversion I run stands on two numbers: hours per week and weeks per year. The standard full-time convention, used by the Bureau of Labor Statistics and by every calculator on this site, is 40 hours a week for 52 weeks — a 2,080-hour work year. If you work part-time, seasonally or on a compressed schedule, your personal hours figure replaces the 2,080, and every result below scales with it. I will flag each place the assumption enters, because swapping it silently is how two people with the same wage end up quoting different incomes.

How to calculate annual income from an hourly wage

The recipe is: hourly rate × hours per week × 52. At the standard 40 hours that collapses into a single multiplication — rate × 2,080. Working it through at $25 an hour: $25 × 40 = $1,000 a week, and $1,000 × 52 = $52,000 a year. Run it backwards as a check and $52,000 ÷ 52 ÷ 40 returns exactly $25, which is how I verify every conversion on this page: both directions, every time.

Part-time pay uses the identical recipe with your real hours. At $22 an hour for 25 hours a week: $22 × 25 = $550 a week, and $550 × 52 = $28,600 a year. Notice that nothing about the method changed — only the hours assumption did. If your hours swing from week to week, average the last month or two of schedules first and convert the average; converting a single busy week produces an income you do not actually have.

From a weekly, biweekly or monthly amount instead

If you already know a larger-period figure, skip the hourly step and multiply by the number of periods in a year:

• Weekly pay → annual: multiply by 52. A $1,000 weekly paycheck is $52,000 a year.
• Biweekly pay → annual: multiply by 26. A $2,000 biweekly paycheck is $52,000 a year.
• Monthly pay → annual: multiply by 12. A $4,333.33 monthly salary is $52,000 a year (allowing a rounding cent).

The trap I see most often is the biweekly one: people multiply a biweekly check by 24 because “twice a month” feels like 24. It is 26 — there are 52 weeks in a year, not 48 — and the missing two checks are real money. Our pay calculator runs all of these conversions in every direction at once, so you can watch the figures agree with each other instead of trusting a single multiplication.

The reference table: $15 to $50 an hour

These are the conversions I look up most, all at 40 hours a week and 52 weeks a year:

Full-time convention throughout: 40 hours a week, 52 weeks, 2,080 hours a year. Monthly figures are the annual amount divided by 12.

How to calculate monthly income

Monthly income is where budgets live, so this is the conversion lenders and landlords actually use. The method: take the annual figure and divide by 12. Our $52,000 example gives $52,000 ÷ 12 = $4,333.33 a month. Going directly from an hourly wage, there is a shortcut worth memorising: a month contains, on average, 2,080 ÷ 12 ≈ 173.33 paid hours, so hourly rate × 173.33 lands on the same answer — $25 × 173.33 ≈ $4,333.33. What you must not do is multiply a weekly paycheck by 4: a month is not four weeks, and that shortcut quietly deletes a month of income across a year.

Two adjustments that change the real answer

Paid time off and the effective rate. The conversions above value every scheduled hour. Our pay calculator’s time-off example shows what changes when you count only days actually worked: at $30 an hour, 8 hours a day across 260 weekdays, the headline figure is $62,400 — but with 10 holidays and 15 vacation days (235 working days), the pay for time actually worked is $56,400, an effective rate of $27.12 an hour instead of $30. Salaried staff are paid the same either way; the effective rate is the honest number for comparing two job offers with different leave allowances.

Bonuses and overtime. Gross annual income means everything an employer pays you before taxes and deductions, so a full answer adds the extras to the base: a $52,000 base salary plus a $3,000 annual bonus is a $55,000 gross annual income. Regular overtime belongs in the total too — convert your typical overtime hours at their premium rate and add them the same way. Leaving these out understates your income on exactly the forms, like loan applications, where understating it works against you.

One direction this article deliberately leaves out: turning a salary into its hourly equivalent when you change jobs or go freelance. That is the same arithmetic read backwards, and our salary calculator is built specifically for that comparison.
