Simple Salary Calculator: Hourly to Annual ConversionUnderstanding how your hourly wage translates into an annual salary is useful whether you’re negotiating a job offer, budgeting, or comparing full-time and part-time opportunities. This guide explains the math behind converting hourly pay to yearly earnings, factors that affect the calculation, tax and deduction considerations, and provides examples and a simple salary calculator you can use immediately.
Why convert hourly to annual?
Many job listings show pay as an hourly rate, while bills, budgets, and salary offers are often discussed annually. Converting hourly to annual pay helps you:
- Compare jobs that use different pay structures.
- Estimate take-home pay and plan a budget.
- Negotiate salary or hourly raises with clear targets.
The basic formula
To convert an hourly wage to an annual salary, use this core formula:
Annual Salary = Hourly Rate × Hours per Week × Weeks per Year
Common assumptions:
- Full-time work is typically 40 hours per week.
- A standard year is often assumed as 52 weeks.
Using these assumptions:
- Annual Salary = Hourly Rate × 40 × 52 = Hourly Rate × 2,080
So an hourly wage of $20 becomes:
- \(20 × 2,080 = **\)41,600 per year**
Adjusting for part-time or overtime
If you work part-time or have varying hours, plug your average weekly hours into the formula.
Example: 25 hours/week at $20/hour:
- Annual Salary = \(20 × 25 × 52 = **\)26,000**
Overtime: If overtime is paid (e.g., time-and-a-half for hours over 40), calculate regular pay for 40 hours and add overtime pay separately.
Example: $20/hour, 45 hours/week with overtime at 1.5×:
- Regular: \(20 × 40 = \)800/week
- Overtime: \(20 × 1.5 × 5 = \)150/week
- Total/week = \(950 → Annual = \)950 × 52 = $49,400
Weeks worked per year: vacation, unpaid leave, and holidays
Not everyone works all 52 weeks. Adjust the formula for paid time off or unpaid leave:
- If you get 2 weeks of unpaid leave: use 50 weeks.
- If you have paid vacation, you can still use 52 weeks for gross pay (paid time off is included in salary).
Example: $20/hour, 40 hours/week, 2 weeks unpaid:
- Annual Salary = \(20 × 40 × 50 = **\)40,000**
Taxes, deductions, and take-home pay
Gross annual salary is before taxes and deductions. To estimate take-home pay, subtract estimated taxes and other deductions:
Common deductions:
- Federal income tax
- State income tax (varies or zero in some states)
- Social Security (U.S. 6.2% up to wage base)
- Medicare (U.S. 1.45%)
- Retirement contributions (e.g., 401(k))
- Health insurance premiums
A simple rough estimate: assume 20–30% of gross pay goes to combined taxes and typical deductions (this varies widely).
Example: $41,600 gross with 25% deductions:
- Take-home ≈ \(41,600 × (1 − 0.25) = **\)31,200**
For precise numbers, use your tax bracket, state rates, and specific deductions.
Benefits and non-wage compensation
When comparing jobs, include non-wage benefits:
- Employer retirement match
- Health insurance value
- Paid time off
- Bonuses, commissions, and stock options
These can add significantly to total compensation and should be converted to annual values when comparing offers.
Hourly to annual calculator (step-by-step)
- Choose your hourly rate.
- Enter average hours per week.
- Enter expected weeks worked per year.
- Multiply: Hourly rate × Hours/week × Weeks/year = Annual gross pay.
- Subtract estimated deductions (taxes, benefits) for net pay.
Quick example form:
- Hourly rate = $18
- Hours/week = 30
- Weeks/year = 52
- Annual gross = \(18 × 30 × 52 = **\)28,080**
- Estimated net (20% deductions) = $22,464
Examples for different scenarios
- Part-time student job: \(12/hour, 15 hours/week, 30 weeks/year → \)12 × 15 × 30 = $5,400
- Full-time with vacation: \(25/hour, 40 hours/week, 52 weeks/year → \)25 × 2,080 = $52,000
- Freelance with seasonal work: \(40/hour, 20 hours/week, 40 weeks/year → \)40 × 20 × 40 = $32,000
Common questions
-
Q: Does the formula account for taxes?
A: No — it gives gross pay. Subtract taxes/deductions for net pay. -
Q: How to include bonuses or commissions?
A: Convert them to annual amounts and add to the gross salary. -
Q: What about hourly pay with varying schedules?
A: Use an average weekly hours figure based on recent months.
Quick reference table
| Scenario | Formula | Example result |
|---|---|---|
| Standard full-time | Hourly × 40 × 52 | \(20 → **\)41,600** |
| Part-time | Hourly × Hours/week × 52 | \(18, 25 hrs → **\)23,400** |
| Overtime | Regular + OT pay × 52 | \(20, 45 hrs → **\)49,400** |
| Reduced weeks | Hourly × Hours/week × Weeks/year | \(20, 40 hrs, 50 wks → **\)40,000** |
Final tips
- Use 2,080 hours/year for standard full-time conversions.
- Adjust weeks/hours for unpaid leave, seasonal work, or overtime.
- Include benefits and taxes when comparing total compensation.
