A job offer lands with a number like "$27.50 an hour," and the question that follows is almost always the same one: what does that actually come out to for the year? Multiplying by 40 and 52 feels simple enough, until part-time hours, unpaid time off, or a chunk of overtime show up and the quick napkin math stops matching the real number on a pay stub.
Converting an hourly wage into an annual salary is straightforward once the formula accounts for how many hours are actually paid across the year — not just how many hours are scheduled in a typical week. This guide covers the standard formula, how to adjust it for common real-world situations, and the mistakes that quietly throw the number off.
To convert an hourly wage to an annual salary, multiply the hourly rate by the number of hours worked per week, then multiply that by 52 weeks. A full-time schedule of 40 hours a week comes out to 2,080 hours a year, so a $25 hourly rate works out to $52,000 a year before taxes. Adjust the weekly hours figure for part-time schedules, and subtract any unpaid time off for a more accurate total.
What is an hourly-to-annual conversion, and what are the options?
Turning an hourly wage into a yearly figure isn't a single fixed formula — it depends on how many hours are actually worked and paid across the year.
- Standard full-time conversion assumes a 40-hour week across all 52 weeks of the year, for a baseline of 2,080 paid hours.
- Part-time conversion swaps in the actual weekly hours worked, since fewer scheduled hours mean fewer hours in the yearly total.
- Adjusted-for-time-off conversion subtracts unpaid vacation, sick leave, or holidays from the 2,080-hour baseline before multiplying by the hourly rate.
- Overtime-inclusive conversion calculates regular and overtime hours separately, since overtime is typically paid at 1.5 times the base rate.
All four start from the same hourly rate; the difference is entirely in how many hours get counted as paid time across the year.
Why the right calculation matters
Using the wrong hours assumption doesn't produce an error — it just produces a number that sounds plausible but doesn't match reality. That shows up in a few common places:
- Comparing job offers. A salaried offer and an hourly offer can't be compared fairly until the hourly rate is converted using the same weekly-hours assumption both employers actually intend.
- Budgeting and loan applications. Lenders and landlords often ask for annual income, and using the standard 2,080-hour baseline for someone who regularly works fewer hours overstates what's actually available.
- Part-time and seasonal work. Applying the full-time 40-hour assumption to a 20-hour-a-week job doubles the real annual figure.
- Negotiating a raise. Knowing the accurate annual equivalent of an hourly rate makes it possible to benchmark against salaried roles doing similar work.
Step-by-step: converting hourly pay to annual salary
Method 1: Standard full-time conversion
- Start with the hourly rate. For example, $25 per hour.
-
Multiply by the standard weekly hours. A full-time schedule is typically 40 hours a week.
$25 × 40 hours = $1,000 per week
-
Multiply the weekly total by 52.
$1,000 × 52 weeks = $52,000 per year
Method 2: Part-time or custom weekly hours
- Replace 40 with the actual weekly hours worked. For example, 25 hours a week instead of 40.
-
Multiply hourly rate by weekly hours, then by 52.
$25 × 25 hours × 52 weeks = $32,500 per year
Method 3: Adjusting for unpaid time off
- Subtract unpaid weeks from 52. For example, two unpaid weeks of leave leaves 50 paid weeks.
-
Multiply hourly rate by weekly hours, then by the adjusted number of weeks.
$25 × 40 hours × 50 weeks = $50,000 per year
Method 4: Adding overtime pay
- Calculate the base annual pay using regular hours at the standard rate, as in Method 1.
-
Calculate overtime pay separately at the overtime rate, commonly 1.5 times the base hourly rate.
Overtime pay = overtime hours × (hourly rate × 1.5) × weeks worked
- Add the base pay and overtime pay together for the total annual figure.
Common mistakes when converting hourly pay
1. Assuming every week is a full 40-hour, paid week
The standard 2,080-hour baseline assumes 52 fully paid weeks, which overstates the real total for anyone who takes unpaid leave, works a seasonal schedule, or has irregular hours.
2. Using the full-time hours assumption for a part-time job
Multiplying an hourly rate by 40 hours a week when the actual schedule is 20 or 25 hours produces an annual figure that's roughly double what the job actually pays.
3. Folding overtime into the standard rate
Overtime hours are usually paid at 1.5 times the base rate, so treating them as regular hours in the yearly total understates the actual annual income for anyone who regularly works overtime.
4. Confusing gross pay with take-home pay
The hourly-to-annual formula produces a gross figure before taxes and other deductions, so comparing it directly to a take-home number from a pay stub will always look too high.

| Factor | Standard full-time | Part-time | Overtime-inclusive |
|---|---|---|---|
| Base assumption | 40 hrs/week, 52 weeks | Actual weekly hours | 40 hrs/week + extra hours |
| Accounts for unpaid leave | No, unless adjusted | No, unless adjusted | No, unless adjusted |
| Accounts for higher overtime rate | No | No | Yes |
| Best for | Salaried job comparisons, standard offers | Part-time, seasonal, or freelance work | Roles with regular overtime hours |
