Converting an hourly wage to an annual salary sounds simple — multiply hours by weeks, multiply by your rate. But the number that actually matters for financial planning is not the gross annual figure: it is the after-tax amount that lands in your bank account each pay period. This calculator handles both steps transparently, using 2025 federal and state tax data so the result reflects reality rather than a rough estimate.
Step 1 — The core multiplication
The formula is: Annual Salary = Hourly Rate × Hours Per Week × Weeks Per Year. At the full-time standard of 40 hours per week, 52 weeks per year, the multiplier is 2,080. A $20/hour worker earns $41,600 gross per year. A $25/hour worker earns $52,000. A $35/hour worker earns $72,800. The 2,080-hour multiplier is the standard used in most job postings when converting between hourly and salaried compensation — but it assumes no unpaid time off, which is a significant caveat covered in the "Weeks Per Year" field below.
The per-period conversions follow directly: divide the annual figure by 52 for weekly pay, by 26 for bi-weekly (the most common pay frequency in the US, used by about 36% of employers), by 24 for semi-monthly, and by 12 for monthly. These gross-pay figures are what appear on your pay stub before any deductions.
Step 2 — Why weeks per year matters more than you think
The single largest hidden variable in hourly-to-annual conversions is the number of weeks actually worked. The 52-week default assumes you receive full compensation for every week of the year — either because you work every week or because your employer provides fully paid time off. For workers without paid vacation, every week taken off reduces actual annual earnings by one week of wages. Two weeks unpaid leave at $20/hr drops annual earnings from $41,600 to $40,000. Four weeks drops it to $38,400 — a $3,200 difference from the headline annual figure that job postings imply.
Gig workers, freelancers, seasonal employees, and independent contractors particularly need this adjustment. A rideshare driver who effectively works 45 weeks per year (accounting for slow periods, maintenance weeks, and time off) should use 45 in this field, not 52. A teacher working a 10-month contract is closer to 43 weeks. Adjusting weeks per year gives a more realistic annual income picture for tax planning and budgeting.
Step 3 — Federal income tax on hourly wages
Once annual gross income is established, federal income tax is calculated using the same progressive bracket system that applies to salaried workers. For 2025, the seven brackets are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The first step is to subtract the standard deduction — $15,000 for single filers, $30,000 for married filing jointly — to arrive at taxable income. Then each bracket's rate applies only to the slice of income within that bracket, not the whole amount.
For a $20/hr full-time worker filing single in 2025: gross = $41,600, taxable income = $41,600 − $15,000 = $26,600. Federal tax: 10% on the first $11,925 ($1,193) + 12% on the remaining $14,675 ($1,761) = $2,954 total federal income tax. Effective federal rate: 7.1%. That is a very different number from the marginal 12% rate, and it matters enormously for financial planning.
Step 4 — State income tax and FICA
State income taxes vary enormously. Nine states impose no income tax on wages: Alaska, Florida, Nevada, New Hampshire (on earned income), South Dakota, Tennessee (on earned income), Texas, Washington, and Wyoming. In these states, the gap between gross and net is primarily FICA taxes plus federal income tax. At the other extreme, California's progressive rates reach 9.3% for income between $68,350 and $349,137, meaning a California worker earning $41,600 faces an additional 2%–6% state tax on top of federal liability.
FICA — the Federal Insurance Contributions Act — funds Social Security and Medicare. Regardless of filing status, state, or deductions, every employee pays 6.2% for Social Security on the first $176,100 of wages (2025) and 1.45% for Medicare on all wages. For a $41,600 annual earner, FICA equals $3,182 per year, or $122 per bi-weekly paycheck. This is why take-home pay is always materially less than gross: even a worker with zero federal income tax liability (which can happen at very low incomes) still owes FICA.
Worked example: $20/hr, single filer, Texas, 40 hrs × 52 wks
Gross: $41,600 → Federal tax: −$2,954 → State tax: $0 (Texas) → Social Security: −$2,579 → Medicare: −$603 → Annual take-home: ≈$35,464 → Bi-weekly net: ≈$1,364
