Annual income is a conversion, and the number that does the converting is how many of whatever period you are paid in fit into a year. Pick the period, enter the amount that comes with it, and this page multiplies. An hourly rate is multiplied by 2,080; a daily rate by 260; a weekly rate by 52; a monthly rate by 12. Those four numbers are conventions rather than facts, and the page shows you which one it used so you can see the assumption rather than inherit it silently. A weekly rate of 1,250 gives 65,000 a year, which is 5,416.67 a month and 250 a day, and the weekly row comes back as 1,250.00 because the weekly figure is the one you typed. Two of those four conventions are worth knowing about because they are the ones that do not divide evenly. A year is not exactly 52 weeks; it is 52 weeks and a day, two in a leap year, so a rate quoted per week and paid per week does not line up with the calendar the way the table suggests. And a month is not four weeks, which is why 65,000 a month divided down gives 5,416.67 rather than the 5,000 that four weeks of 1,250 would suggest. If the number you are starting from is an hourly rate and what you also know is how many hours a week and how many weeks a year you actually work, this is the wrong page: the two pages that take those as inputs are the ones that let you change the assumption instead of accepting it. The table below lists the four periods with the count each one uses and, in the last column, what makes that count move.
How many of each period fit into a year
| Period | Periods in a year | What makes it change |
|---|---|---|
| Hourly | 2,080 | Two thousand and eighty periods in a year, which is forty hours a week for fifty-two weeks. It is the convention behind nearly every salary-to-hourly conversion, and it is not the only figure in use: a divisor of 2,087 is used where the leap-year drift matters. It moves whenever your weekly hours change, and it moves a lot — a four-day week at eight hours is not 80 percent of this number, it is a different number entirely. |
| Daily | 260 | Two hundred and sixty periods in a year, which is five weekdays a week for fifty-two weeks. What this count does not change for is holidays and paid leave, because a paid day off is still a paid day; it changes the moment you work a four-day week, or a season rather than a year. It is also the count that gets mistaken for the number of days in a year, which is why the daily row of a monthly rate can look surprisingly small. |
| Weekly | 52 | Fifty-two periods in a year. This is the one count in the table that is not exact: a year is 52 weeks and a day, and two days in a leap year, which is why a rate paid every week produces 53 paydays in some years. Nothing on this page accounts for that — it divides the year into fifty-two equal parts and says so, and the page about biweekly pay is where the extra payday is dealt with. |
| Monthly | 12 | Twelve periods in a year, and the count that causes the most confusion. Fifty-two weeks divided by twelve is 4.33, not four, so a monthly figure is not four weekly ones and a weekly figure is not a quarter of a monthly one. A monthly contract is quoted this way for that reason: the payment lands on the same date every month, and the length of the month is not part of the deal. |
The middle column is what this page multiplies by, and it is printed so the assumption is visible rather than buried. The last column is the one worth reading, because it separates the two counts that are conventions from the two that are exact arithmetic and still surprise people. Weekly and monthly are the awkward pair: a year is 52 weeks and a day, and a month is not four weeks, so a rate quoted in one of those periods does not convert cleanly into the other. Both errors are small enough to ignore in a single year and large enough to notice when you compare two offers or run the figures over a decade. Nothing else on this page changes those counts. They follow from the period you pick and not from the amount, so a zero amount still shows a count, and a very large one does not change it either.
Formula
Annual income ＝ amount per period × periods in a year
- amountPerPeriod
- The amount that comes with one period — one hour, one day, one week or one month, whichever you selected. It is deliberately not an annual figure: this page multiplies, so the annual figure is what comes out, not what goes in. Entering an amount of zero is allowed and produces zero everywhere, because earning nothing in a period is a real situation rather than an error.
- amountPeriod
- Which period the amount belongs to, and the one field that changes the arithmetic rather than the wording. An hourly rate is multiplied by 2,080, a daily rate by 260, a weekly rate by 52, and a monthly rate by 12. Choosing the wrong one here does not produce an error; it produces a plausible number that is wrong by a factor of five or twelve, which is why the last row of the panel prints the count that was used.
- periodsPerYear
- How many of your chosen periods this page decided fit into a year. It is looked up rather than calculated, so it stays the same whatever amount you type — a zero amount still shows 260 if you chose a daily rate. It is on the panel for one reason: the assumption should be visible. If it is not the assumption you want, the two pages that take hours a week and weeks a year as inputs are where to go.
- annualIncome
- The result, and the figure this page exists to produce. Everything below it is derived from it rather than computed separately, so the monthly, weekly and daily rows are three views of this one number rather than three independent calculations. That is why they can disagree in the last decimal with the amount you typed: once the annual figure has been rounded, dividing it back down does not always return where you started.
- monthlyIncome
- The annual figure divided by twelve. It is the row most people are actually after, and it is also the row that most often looks wrong: a monthly rate of 4,200 and a weekly rate of 1,250 are close to the same annual income, but the monthly row of a weekly rate is not four times the weekly one. Twelve months do not divide into fifty-two weeks evenly, and this row is where that shows up.
- weeklyIncome
- The annual figure divided by fifty-two. If you entered a weekly rate this row returns exactly what you typed, which makes it the one line on the panel you can check without a calculator. For every other period it is a derived figure, and the figure is what a year of your income averages to per week — not what any particular week pays, since no work schedule is that even.
- dailyIncome
- The annual figure divided by 260, the number of weekdays in a year. It is a rate rather than a schedule: it spreads the whole year over working days, so it does not know about public holidays, paid leave or a four-day week. It is useful for comparing a daily rate against an annual salary, and misleading if you read it as what a day actually pays.
Use it when you know what you are paid per period and want the yearly figure — a job advert quoting a daily rate, a contract quoting a monthly one, a side job quoting an hourly one. Use it also to compare two offers quoted in different periods, because converting both to a year is the only way the comparison is fair. Do not use it when what you actually know is your hours a week and your weeks a year: those are inputs this page does not have, and the pages that do take them will give you a different answer that is the one you want. Do not use it for take-home pay either. Nothing here subtracts tax, a pension contribution or an insurance premium, and every figure on the panel is before any of them.
Worked examples
Default case: 1,250 a week
- Periods in a year: 52（weekly rate）
- Annual income: 1,250 × 52 ＝ 65,000
- Monthly: 65,000 ÷ 12 ＝ 5,416.67 Weekly: 65,000 ÷ 52 ＝ 1,250.00 Daily: 65,000 ÷ 260 ＝ 250.00
The weekly row gives back exactly what was typed, because the figure it divides is the one that came from multiplying it. The monthly row does not: 5,416.67 is not four weeks of 1,250, and it is not supposed to be. Twelve months and fifty-two weeks are two different ways of cutting the same year, and they only agree to two decimal places.
Hourly: 30 an hour
- Periods in a year: 2,080（40 hours a week for 52 weeks）
- Annual income: 30 × 2,080 ＝ 62,400
- Monthly: 62,400 ÷ 12 ＝ 5,200 Weekly: 62,400 ÷ 52 ＝ 1,200 Daily: 62,400 ÷ 260 ＝ 240
These are the same numbers the hourly to salary page produces from the same rate, because the assumption underneath is the same one: forty hours a week, fifty-two weeks a year. That page is the one to use if either of those is not true for you, since it takes both as inputs. This one takes the convention, and here it is spelled out.
Monthly: 4,200 a month
- Periods in a year: 12（months）
- Annual income: 4,200 × 12 ＝ 50,400
- Weekly: 50,400 ÷ 52 ＝ 969.23 Daily: 50,400 ÷ 260 ＝ 193.85
A monthly rate is the case where the weekly row is least intuitive. 969.23 a week looks low next to 4,200 a month until you multiply it back: 969.23 × 52 is 50,399.96, a little short of the 50,400 the page started from. The four cents are rounding, not an error, and the page does not try to hide the seam by making one row agree with another.
Nothing earned: zero a day
- Periods in a year: 260（weekdays）
- Annual income: 0 × 260 ＝ 0
- Monthly, weekly and daily: all 0
A zero amount is a valid input rather than an empty one, so the panel fills with zeros instead of going blank. Note that the last row still reads 260: the count of periods comes from the period you chose, not from the amount, and it would be a mistake to read that row as part of the calculation.
Limitations
This page multiplies and does not do anything else. It does not know how many hours a week you work or how many weeks a year you work, and if those are the numbers you have, the two pages that take them as inputs are where you should be — this one would answer a question you did not ask, with an assumption you did not choose. It does not subtract anything: no income tax, no social insurance, no pension contribution, no student loan repayment, no union dues. Every figure on the panel is gross. It does not model a schedule. The daily and weekly rows are averages over a year, so they know nothing about public holidays, paid leave, a four-day week, seasonal shutdowns or overtime. It treats a period as a fixed amount, so a variable income — commission, tips, piecework, a fluctuating freelance month — has to be entered as its own average, and the answer is only as good as that average. It does not convert between currencies or attach a currency to anything, which is deliberate: the arithmetic is the same in every one, and a unit would only invite reading the figures as being about a particular place. It does not decide whether the income is taxable, or what counts as income for a particular form; the amounts are whatever you say they are. The two conventions that do not divide evenly are worth repeating here because this page inherits rather than fixes them: a year is 52 weeks and a day, and a month is not four weeks. Both show up as small discrepancies between rows, and both are the reason the pages that let you set the work-year assumption exist.
Frequently asked questions
- Is annual income the same as annual salary?
- Not quite, and the difference is what this page is careful about. A salary is one figure for one job. Income is every amount that comes in, and this page converts one period amount into a year of it. If you have more than one source, convert each and add them; if you want one job's contracted figure, the pages that start from a salary are a better fit.
- Why does the monthly row not equal the weekly row times four?
- Because a month is not four weeks. Fifty-two weeks divide into twelve months at 4.33 weeks each, so multiplying a weekly figure by four understates a month. The page divides the annual figure by twelve instead, which is the convention a monthly contract uses. The gap is small but it grows with the amount, and it is why an offer quoted monthly and an offer quoted weekly have to be converted before they can be compared.
- How many hours are in a work year?
- This page uses 2,080, which is forty hours a week for fifty-two weeks. It is a convention rather than a fact, and it is not the only one in use: 2,087 is the divisor the United States federal government uses for converting salaries to hourly rates, because it accounts for the extra day in leap years over a long span. The difference is about 0.3 percent, which is small per hour and visible per year.
- Should I use 260 days or 365 for a daily rate?
- 260, which is five weekdays a week for fifty-two weeks, because that is what a working day means when a rate is quoted per day. Dividing by 365 would spread the income over days you do not work, and would give a daily figure roughly a third smaller. The row is a rate for comparing against other rates, not a statement about what any particular day pays.
- Can I use this for a take-home figure?
- No. Nothing on this page subtracts tax, social insurance, a pension contribution or anything else, so every number is gross. Take-home pay depends on where you live, what you have declared and what you have opted into, and none of that is in these two fields. Convert to gross here, then apply whatever deductions actually apply to you.
- What if my income changes every period?
- Then enter an average, and read the result as an average rather than a prediction. A fluctuating income has no single annual figure, so the honest one is a mean over a period long enough to include the quiet months. If what varies is the number of hours rather than the rate, the two pages that take hours a week and weeks a year are a better shape for the question, because they let the assumption move with your schedule.
