Salary to Contractor Rate: How to Convert
The short answer: multiply your salary by 1.30–1.50 and divide by 1,600 billable hours. A $90,000 salary becomes $73.13–$84.38 an hour; at the standard 1.40 multiplier it is $78.75 an hour, or $630 for an eight-hour day. "I earn $80,000, so I'll contract at $40/hour" — that single sentence loses contractors thousands of dollars a year, because salary ÷ 2,080 ignores benefits, gaps, and the half of payroll tax an employer used to pay. Here's the honest conversion.
Formula: contract hourly rate = salary × (1.30–1.50) ÷ 1,600 billable hours; contract day rate = hourly × 8.
Why salary ÷ 2,080 is wrong
2,080 = 40 hours × 52 weeks. It's the standard full-time year — but a contractor's paid year looks nothing like it. The naive formula ignores:
- Benefits you now fund yourself. Health insurance, retirement match, paid leave, and perks commonly worth $8,000–15,000/year in the US — figures HR consultancies publish annually in total-compensation studies (total comp typically runs 1.25–1.4× salary).
- Unpaid gaps. Between contracts, holidays, and dry spells: realistically 4–8 weeks/year. Even the UK's widely used contractor calculators (e.g., ContractorCalculator) apply a "downtime" discount of 4–8 weeks.
- The employer half of payroll tax. US employees pay 7.65% FICA and their employer pays another 7.65%. Contractors pay both halves via the 15.3% self-employment tax (see the IRS SE tax rules).
The correct formula
Contract hourly rate = (salary + self-funded benefits) × (1 + extra tax burden) ÷ (actual working hours)
Worked example — $80,000 salary, $8,000 benefits, 7.65% extra tax burden, 47 working weeks at 40 hours:
- Gross-up: ($80,000 + $8,000) × 1.0765 = $94,732
- Hours: 47 × 40 = 1,880
- Rate: $94,732 ÷ 1,880 = $50.39/hour
Not $38.46 — that naive figure is what a straight salary-to-hourly division gives (see our salary to hourly calculator for the exact conversion on any schedule). And many contractors add a 10–20% risk premium on top for the lack of job security — pushing an $80k salary to $55–60/hour. Use our salary ⇄ contract converter to run your own numbers.
Worked example: $90,000 to a day rate
Take a $90,000 salary and convert it end to end:
- Base hourly at the contractor year: $90,000 ÷ 1,600 = $56.25/hour
- Apply the standard 1.40 multiplier: $56.25 × 1.40 = $78.75/hour (equivalently $90,000 × 1.40 = $126,000, and $126,000 ÷ 1,600 = $78.75)
- Range at 1.30–1.50: $73.13–$84.38/hour
- Day rate at eight hours: $78.75 × 8 = $630/day, within a $585–$675 range
Compare that with the naive conversion: $90,000 ÷ 2,080 = $43.27 an hour. The gap between $43.27 and $78.75 is $35.48 an hour — at 1,600 hours, $56,768 a year of value handed over because someone divided by the wrong number. These are planning ranges rather than guarantees; your market, downtime and risk decide where in the range you land.
Salary converted at three multipliers
| Salary | ×1.30 (tight budgets, short gaps) | ×1.40 (standard) | ×1.50 (high risk) | Day rate at ×1.40 (8 hrs) |
|---|---|---|---|---|
| $70,000 | $56.88 | $61.25 | $65.63 | $490 |
| $90,000 | $73.13 | $78.75 | $84.38 | $630 |
| $110,000 | $89.38 | $96.25 | $103.13 | $770 |
| $130,000 | $105.63 | $113.75 | $121.88 | $910 |
Every cell is salary × multiplier ÷ 1,600, rounded to the cent; the day column is the ×1.40 rate × 8. Quote from the table, then discount only for genuinely strategic work — never as an opening position.
Why 1,600 hours, not 2,080
2,080 is what an employee is paid for: 40 hours × 52 weeks, weekends and leave already covered. A contractor sells a shorter year. Two clean ways to arrive at 1,600: forty working weeks × forty sellable hours, or fifty weeks × thirty-two. Either way you have reserved roughly a quarter of the year for sales work, admin, downtime between contracts, and the days nobody pays for. Using 2,080 as your denominator doesn't make you cheaper — it makes your rate look bigger than the money that actually arrives, and the shortfall surfaces later as a thin December.
What the multiplier buys
The uplift is not a margin for greed; it is a list of things your employer used to fund:
- Benefits you now buy yourself. Health insurance, retirement match, paid leave and perks commonly worth $8,000–15,000 a year in the US — HR consultancies put total compensation at roughly 1.25–1.4× salary. A practical overview sits in our health insurance guide.
- The employer's half of payroll tax. Employees pay 7.65% FICA and the employer pays another 7.65%; contractors pay both halves through the 15.3% self-employment tax (see the IRS SE tax rules).
- Unpaid gaps. Holidays, sick days, and 4–8 weeks between contracts, on top of the sales time that fills them.
- Business overhead. Software, hardware, insurance, accounting, payment fees, and the hours spent invoicing and chasing payment.
- Risk. No notice period, no severance, no guaranteed next contract. A 10–20% premium above the pure cost calculation is common for that alone.
Choosing your multiplier
Use 1.20–1.30 when contracts are long, downtime is minimal, and you keep an employee-grade benefits package. Use 1.30–1.40 as the default for most independent conversions. Use 1.40–1.60 when you are buying your own health cover, gaps run long, the client offers no pipeline certainty, or you are carrying specialist risk. If a role is inside-IR35 in the UK, or otherwise taxed like employment, start higher — the tax already takes part of the uplift.
A quick sanity check: the rule of 1,000
Recruiters use a rough heuristic: salary ÷ 1,000 ≈ equivalent contract rate ($80k → $80/hour). That rule builds in benefits, gaps, taxes, and margin — it's aimed at high-end consulting. If a recruiter offers you salary ÷ 2,080 as a "conversion," they're offering you a pay cut wrapped in arithmetic.
Using it in reverse
Got a contract offer? Convert it backward to a salary equivalent and compare with your current job. If the equivalent salary comes out lower, you're being paid less for more risk — walk or negotiate. The calculator runs both directions.
Quote shape: hourly, day, or project
The converted number is your floor, not automatically your quote. Hourly billing suits fluid scope and keeps the arithmetic visible; day rates suit presence-shaped work — workshops, embedded sprints, client on-sites — and convert cleanly from this figure (our day rate converter does the multiplication, and the conventions are explained in the day rate guide). Fixed project pricing suits work you deliver faster than the client expects, in which case the same hourly floor divided by your real delivery hours tells you the lowest bid you can afford. In all three shapes the floor is the same: salary × multiplier ÷ 1,600, plus whatever risk premium your situation justifies. Quote below that floor and you have simply recreated employment — with worse benefits.
Contractor vs employee: the structural comparison
Rate math only works once the two deals are compared honestly. Side by side:
| Dimension | Contractor | Employee |
|---|---|---|
| Pay basis | Per hour or project, invoiced on agreed terms | Salary, paid weekly, biweekly, or monthly |
| Tax handling | Self-employed: pays own income tax plus both halves of Social Security and Medicare, with business-expense deductions | Employer withholds federal, state, and payroll tax; receives a W-2 |
| Benefits | Self-funded — health cover, retirement, time off all come from the rate | Employer-provided health, retirement match, and paid leave |
| Job security | None beyond the contract term; gaps between clients are normal | Notice periods, severance norms, unemployment insurance |
| Typical premium | Charges 15–40% above the equivalent hourly wage | Costs the employer 50–70% above salary once loaded (see below) |
The two premium figures measure different things, which is why sources seem to disagree: the 15–40% is what the contractor charges over the wage to stay whole, while the 50–70% is what the employer spends over salary once payroll taxes, insurance, and overhead land. Quote with the first number; hire with the second.
Switching from employee to contractor: pros and cons for you
Conversion math tells you the rate; this decides whether you want the deal. The same inputs behind the 1.30–1.50 multiplier and the 1,600-hour year explain both sides.
- Choose your schedule, clients, and methods. Contracting trades a set rota for control over when, where, and how you deliver, including turning down poor fits.
- Vary the work and widen income sources. Multiple clients replace one employer, building broader experience instead of single-company depth.
- Deduct genuine business costs. Equipment, travel, software, and insurance reduce taxable profit in ways salary cannot.
- Quote a higher headline number. The 15–40% uplift over the wage funds what salary bundled silently.
- Absorb gaps and dry spells. Four to eight weeks a year without billing is normal, which is why the denominator drops to 1,600.
- Buy every benefit yourself. Health cover, retirement, and paid leave worth $8,000–15,000 come from the same rate.
- Carry both tax halves and the admin. The extra 7.65% plus quarterly set-asides, invoicing, and chasing payment sit with you.
Switch when control and variety outweigh gaps and self-funded cover, and only at a rate that survives the 1,600-hour test above — otherwise the freedom reprices as a cut with thinner protection.
Country notes
UK contractors: IR35 status changes the tax math substantially — inside-IR35 contracts need higher rates to net the same. EU contractors: add your country's social-contribution percentage the same way the US adds 7.65%.
