What is this calculator for?
The job listing says "$28-35/hour, full-time." You want to know what that means annually, what your biweekly paycheck would be, what your monthly take-home roughly looks like. Or you've been earning $74,000 a year salaried for three years and you're considering switching to hourly contract work — what hourly rate is equivalent. The salary converter handles all directions: hourly to annual, annual to hourly, monthly to biweekly, contractor day-rate to salaried equivalent.
The math: standard full-time year = 2,080 hours (40 hours/week × 52 weeks). $28/hour × 2,080 = $58,240/year. $35/hour × 2,080 = $72,800/year. Biweekly pay (most common US frequency): annual ÷ 26 paychecks. Semi-monthly (24/year): annual ÷ 24. Monthly (12/year): annual ÷ 12. Weekly (52/year): annual ÷ 52. Each pay frequency produces slightly different per-paycheck amounts despite identical annual totals.
This calculator handles all conversions plus contractor-to-employee equivalence: contractors earning $50/hour gross need approximately $50 × 2,080 ÷ 1.4 ≈ $74,000 salaried W-2 equivalent to match net income after accounting for self-employment tax, health insurance costs, and unpaid time off. The "1.4 multiplier" reflects typical contractor cost burden.
How to use this calculator
Pick your conversion direction: hourly to annual, annual to hourly, annual to biweekly, etc. The calculator handles all 16 combinations of hourly/daily/weekly/biweekly/semi-monthly/monthly/annual.
Enter your source amount and source frequency. For unusual hours (part-time, overtime-heavy roles, contractor billing): enter your actual expected weekly hours rather than the default 40.
For contractor/freelancer conversions, enable the contractor toggle. The calculator subtracts self-employment tax (15.3% on net earnings up to Social Security wage base), estimates unpaid time off (10 days vacation + 5 sick + 8 holidays = ~3 weeks unbillable per year = ~6% rate adjustment), and accounts for health insurance ($600-1,500/month for individual ACA plan, $1,400-2,500/month for family). The output is a more honest "what you actually keep" comparison vs a salaried equivalent.
For relocation scenarios: enter your current salary and city, target city, and the calculator can integrate with cost-of-living data to show purchasing-power equivalent in the new location.
Understanding your results
The calculator returns your amount in each common frequency (hourly, daily, weekly, biweekly, semi-monthly, monthly, annual). For contractor mode: gross hourly rate, after-SE-tax hourly, after-health-insurance hourly, and W-2 salaried equivalent.
How to read it. $30/hour full-time = $62,400/year = $5,200/month = $2,400 biweekly = $1,200 weekly = $240 daily. Same total, different cadences. People sometimes underestimate or overestimate compensation when seeing it in unfamiliar frequencies — a "$2,400 biweekly" job is identical to a "$62,400 annual" job, but the biweekly number sounds smaller emotionally.
The contractor calculation. $50/hour contractor with no benefits: gross $104,000/year (2,080 hours). SE tax: 15.3% on first $176,100 (2026 Social Security cap) + Medicare on excess = roughly $14,500. Health insurance: $900/month family plan = $10,800/year. Unpaid PTO/sick/holiday (15 days/year): $6,000 of unbilled time. Effective W-2 equivalent: $72,700 — the gross of $104K reduces to about $72K of "fair comparison" against a salaried role. Contractors pricing themselves below 1.3-1.4× the equivalent salary rate often realize too late they're underpaid.
The annual-to-hourly insight. $85,000 salary ÷ 2,080 = $40.87/hour standard. But many salaried professionals work 45-55 hours/week, not 40. Real hourly equivalent: $85K ÷ (50 hours × 52 weeks) = $32.69/hour. When a salaried professional considers a $45/hour contract role with similar total hours, the contract's hourly rate doesn't look as impressive if you account for the actual hours worked at the salaried job. The Mubboo perspective: salaried jobs commonly hide their effective hourly rate behind the "we don't track hours" framing.
Reality check on offers. Job offer comparison should use hourly rates accounting for actual expected hours, plus benefits value (health insurance is worth $10K-25K depending on family situation; retirement match is worth $3K-15K depending on income), plus equity (RSUs, options, stock plans) annualized over vesting period, plus geographic cost-of-living adjustment. A $130K offer in San Francisco vs $115K in Austin is a Austin-wins comparison after these adjustments. The Mubboo total-compensation calculator handles the full math.
A worked example
James, 32, currently makes $78,000 salaried at a marketing agency. He's evaluating a contract role at $55/hour, 40 hours/week, with no benefits. He wants to know if it's a raise or a pay cut after factoring in self-employment tax, health insurance, and lost time.
Contract gross: $55 × 40 × 52 = $114,400/year. Looks like a $36K raise.
Contract net adjustments:
Self-employment tax: 15.3% on first $176,100, Medicare 2.9% above + 0.9% Additional Medicare above $200K. On $114,400: ~$15,800 SE tax. (W-2 employees pay only 7.65% FICA; employer covers the other 7.65%; contractors pay both halves as SECA.)
Health insurance: He has ACA Silver plan for himself + wife, $750/month = $9,000/year. (Currently free at his W-2 job.)
Unpaid time off: 10 vacation days + 5 sick + 8 holidays = 23 unpaid days = $10,120 of unbilled time.
Retirement: His current job offers 4% 401(k) match on $78K = $3,120 free. Contract has no match (he'd need to fully self-fund an SEP-IRA or Solo 401(k) for similar tax-advantaged retirement).
Effective contract take-home: $114,400 − $15,800 − $9,000 − $10,120 − $3,120 (lost match) = $76,360. Comparable to the W-2 $78,000.
The contract is roughly a wash — perhaps a slight pay cut once everything is netted. James decides to negotiate the contract rate up to $65/hour to make the math work. At $65/hour × 2,080 hours = $135,200 gross, minus SE tax (~$18,300), minus health ($9K), minus PTO ($11,960), minus lost match ($3,120) = $92,820. Now meaningfully ahead of W-2 by $14,800. He counter-offers; client agrees to $62/hour. Final calculation puts him about $9K ahead of W-2 — modest but real raise plus more flexibility. He accepts.
The lesson: contract hourly rates need to be 1.3-1.5× the apparent salaried hourly equivalent ($78K / 2,080 = $37.50/hour at W-2; contract at $55 is only 1.47× — barely enough; $62 = 1.65× provides real margin). Below 1.3× is a pay cut despite the higher headline number.
